CASE 009
:
THE CASE OF THE EMPTY CELL
Cell 14 was locked. The bars were intact. The cameras showed nothing. The alarms were silent. By every measure Daniel Vanek was still inside Hartwell Prison. But at 6:03 AM he was gone — and the only evidence he left behind was what the forensic team almost missed entirely.
CASE BRIEFING
At 6:03 AM on a Thursday morning, Officer Raymond Costa conducted the morning headcount at Hartwell Maximum Security Prison.
Cell 14 — Daniel Vanek — empty.
Costa checked the cell door. Locked. He checked the window. The three steel bars were intact, undamaged, and firmly set in original concrete. He checked the camera feed. Nothing unusual had been recorded between the 11 PM headcount and 6 AM.
He called the duty supervisor.
Within twenty minutes the entire facility was in lockdown.
A full search of all 340 cells, the exercise yard, the kitchens, the laundry, the workshops, and the medical wing found nothing. Daniel Vanek — inmate number HW-4471, serving 22 years for armed robbery and assault, model prisoner for 14 months — was not inside Hartwell Prison.
He was simply gone.
The warden — Director Margaret Osei — stood in the doorway of Cell 14 and looked at the neatly made bed, the folded prison uniform on the chair, and the personal photographs arranged on the shelf above the desk.
"He planned this," she said. "Every detail. The question is how long — and whether anyone helped him."
The forensic investigation team arrived at 8:45 AM.
Lead investigator Dr. Yemi Adebayo walked into Cell 14, crouched beside the bed, and immediately found the first clue.
A faint smear of reddish-brown soil on the underside of the bed frame — in a cell block built entirely on concrete foundations.
Natural soil had no business being in Cell 14.
"He didn't go through the door," Dr. Adebayo said. "He went through the floor."
Your investigation begins now.
A locked cell. An intact window. A silent alarm system. And a prisoner who vanished between the 11 PM headcount and 6 AM without triggering a single alert.
The soil on the bed frame is your first clue. The engineering that follows will reveal fourteen months of extraordinary planning — and one person inside the prison who made it possible without ever knowing they did.
Examine all five Evidence Files. The physics of soil, sound, structure, and space have preserved a record of everything Daniel Vanek did. Can you reconstruct the escape — and identify the person whose unwitting routine made it possible?

EVIDENCE FILE 01 — CELL 14 FORENSIC EXAMINATION
Case Reference: HWP-2024-0118
Location: Hartwell Maximum Security Prison — Cell Block C — Cell 14
Prepared By: Dr. Yemi Adebayo, Forensic Investigation Unit
Date: Thursday — 9:15 AM
BACKGROUND
Cell 14 is a standard maximum security single occupancy cell — 2.8 metres wide, 3.6 metres long, 2.4 metres high. Reinforced concrete walls, floor, and ceiling. One steel door with electronic locking mechanism. One window — 60 centimetres wide, 30 centimetres high — fitted with three hardened steel bars set in the original concrete. The cell has been occupied by Daniel Vanek for 14 months.
The forensic examination began at 8:45 AM — approximately two hours and forty minutes after the empty cell was discovered.
FINDING 1 — SOIL TRACES
A smear of reddish-brown soil was identified on the underside of the bed frame — specifically on the inner face of the frame's lower crossbar, closest to the floor.
The soil is inconsistent with any material present in the cell or the cell block. Hartwell Prison is constructed entirely on a concrete foundation. No natural soil is present anywhere within the cell block structure.
A sample was collected for laboratory analysis.
Additional soil traces — smaller, partially wiped — were identified along a 40-centimetre section of the floor beside the bed's left leg.
Finding: natural soil was brought into Cell 14 from below.
FINDING 2 — THE BED
The bed frame is a standard issue welded steel unit — bolted to the floor at four points using tamper-resistant fixings.
Dr. Adebayo noted that the two floor bolts on the left side of the bed showed unusual wear patterns on the bolt heads — consistent with repeated removal and replacement using an improvised tool rather than the original installation tool.
The bolts were removed. The left side of the bed frame lifted cleanly from the floor.
Beneath the left side of the bed — concealed by the frame — a section of floor approximately 60 centimetres by 45 centimetres had been removed. The edges were clean and precise. The concrete had not been broken — it had been cut.
FINDING 3 — THE FLOOR SECTION
The removed floor section was found wedged beneath the bed's mattress base — a single concrete panel approximately 8 centimetres thick, cut from the floor using a tool that left smooth edges.
The underside of the panel showed dried soil and scratch marks consistent with repeated handling.
The panel had been cut, removed, used as an access point, and replaced repeatedly over an extended period. The surface of the panel — the side facing up into the cell — had been disguised with a mixture of concrete dust and an adhesive substance to conceal the cut lines.
From above — with the bed in its normal position — the floor appeared completely intact.
FINDING 4 — IMPROVISED TOOLS
A thorough search of the cell revealed the following concealed items:
Behind the rear panel of the desk unit — which had been partially detached and reattached — a collection of improvised tools was found wrapped in cloth torn from a prison-issue towel:
A cutting implement fashioned from a hardened steel bracket — identified as a component of the cell's original ventilation grille, removed and resharpened over time.
Two steel spoons — both with their bowl ends filed to a chisel edge.
A small mirror fragment — from a standard-issue shaving mirror — mounted on a toothbrush handle. Function: to examine the floor area beneath the bed without lying down.
A cloth bag constructed from a prison-issue pillowcase — drawstring fashioned from unravelled sock material. Function: consistent with soil transport.
FINDING 5 — THE DUMMY
The bed, when discovered at 6:03 AM, appeared occupied from the cell door observation window.
The shape beneath the blanket was constructed from:
A prison-issue pillow positioned lengthwise beneath the blanket.
Rolled clothing — two prison uniforms — arranged to create body volume and leg shape.
A head form constructed from a third pillow stuffed into a prison-issue wool hat — positioned at the correct height relative to the body shape.
The construction was sufficient to deceive a visual check through the cell door observation window — a narrow, wire-reinforced glass panel — at low light levels. It would not have survived a cell entry inspection.
The 11 PM check was a visual check through the observation window. The 6 AM check was a full cell entry headcount.
Vanek had a seven-hour window.
YOUR TASK
The forensic examination of Cell 14 has established the following:
Daniel Vanek cut a concealed access panel in his cell floor. He removed and replaced it repeatedly over an extended period — bringing soil up into the cell in a cloth bag and concealing it elsewhere. He constructed a dummy sufficient to deceive the 11 PM visual check. And he descended through the floor between 11 PM and 6 AM on Thursday morning.
What does the evidence tell you about how long this escape was planned? Research how the Alcatraz escape of 1962 was executed — the methods used bear a remarkable similarity to what Dr. Adebayo found in Cell 14.
Consider what questions remain unanswered: where did 14 months of excavated soil go, how did Vanek cut through concrete without being heard, and where does the tunnel lead?
Evidence File 02 will begin to answer those questions.

EVIDENCE FILE 02 — TUNNEL DISCOVERY AND ENGINEERING ANALYSIS
Case Reference: HWP-2024-0118
Evidence Item: EV-02 — Subterranean passage survey
Prepared By: Dr. Yemi Adebayo, Forensic Investigation Unit
Date: Thursday — 1:30 PM
BACKGROUND
Following the discovery of the concealed floor access panel in Cell 14, investigators lowered a camera and lighting equipment into the void beneath the floor.
What they found was not a void.
It was a tunnel.
TUNNEL — PHYSICAL DIMENSIONS
Length: 41.3 metres — measured by laser rangefinder
Width: 58 centimetres — sufficient for a person to crawl through on their elbows
Height: 52 centimetres
Depth below prison floor: 1.1 to 1.4 metres — varying slightly along its length
Direction: bearing 312 degrees — northwest
The tunnel runs in a precise straight line from the access point beneath Cell 14's floor to its exit point — emerging beneath a storage shelf unit in the prison supply corridor outside the secure cell block perimeter.
TUNNEL CONSTRUCTION
The tunnel walls, floor, and ceiling showed evidence of careful engineering.
Wall support:
At intervals of approximately 90 centimetres along the tunnel's length, wooden support frames had been installed — constructed from materials that will be addressed in Evidence File 03. Each frame was precisely fitted to the tunnel's dimensions, preventing collapse of the surrounding soil and concrete rubble.
Floor surface:
The tunnel floor had been smoothed and compacted — creating a surface that allowed crawling movement without noise from shifting loose material.
Direction maintenance:
At the tunnel entrance — immediately below the Cell 14 access panel — investigators found a small compass rose scratched into the concrete wall. Two reference marks 90 centimetres apart along the tunnel's initial section allowed Vanek to maintain a consistent bearing using a compass throughout the excavation. A standard magnetic compass — undetectable by security equipment — is sufficient to maintain tunnel direction over 41 metres with this method.
TUNNEL EXIT
The tunnel exits beneath a heavy steel storage shelf unit in the prison supply corridor — a service area outside the secure cell block perimeter but inside the outer prison wall.
The shelf unit — approximately 2 metres tall, 1.8 metres wide, 60 centimetres deep — is bolted to the floor at its base. However the bolts on the shelf's rear left corner showed identical wear patterns to the bed bolts in Cell 14 — consistent with repeated removal and replacement.
The shelf had been functioning as the tunnel's exit hatch for an undetermined period.
From the supply corridor Vanek had access to the outer prison service yard — used by maintenance contractors — where a drainage channel runs beneath the outer perimeter wall.
The drainage channel measures 55 centimetres wide and 48 centimetres high — sufficient for a person to crawl through.
It exits on the eastern embankment outside the prison perimeter.
ENGINEERING ASSESSMENT
Dr. Adebayo requested an independent structural assessment from civil engineer Dr. Peter Osei — no relation to the prison director.
Dr. Osei's findings:
"The tunnel represents a significant engineering achievement under severe constraints. The builder correctly identified the soil composition at this depth — a mixture of compacted clay and gravel — and selected an appropriate support interval to prevent collapse. The 90-centimetre frame spacing is consistent with published guidance for temporary mine support structures.
The tunnel maintains a consistent depth of approximately 1.1 to 1.4 metres — deep enough to avoid detection by footfall vibration on the surface above but shallow enough to minimize excavation volume.
The bearing of 312 degrees was maintained with sufficient precision to exit within 30 centimetres of the intended target — the shelf unit in the supply corridor. Over 41 metres this represents an angular error of less than 0.4 degrees. This is not luck. This required planning, measurement, and repeated correction during excavation.
Whoever built this tunnel understood what they were doing."
TIMELINE ESTIMATE
Based on the tunnel's volume — approximately 1.24 cubic metres of material excavated — and the realistic rate at which one person working in confined conditions with improvised tools could excavate compacted clay and gravel, Dr. Adebayo estimated:
Working rate: approximately 3 to 5 litres of material per hour under safe noise conditions
Total excavation time: approximately 250 to 400 hours
Spread over 14 months of occupation: approximately 18 to 29 hours per month — less than one hour per day on average
This is consistent with opportunistic excavation during specific periods when conditions allowed — rather than continuous nightly work.
YOUR TASK
The tunnel runs 41.3 metres from Cell 14 to the prison supply corridor — precisely directed to exit beneath a specific shelf unit, through which Vanek accessed the service yard and the drainage channel to freedom.
Two questions now require answers.
First — where did 1.24 cubic metres of excavated soil and concrete rubble go? It did not come up through the cell floor — only trace amounts were found in Cell 14. Research how the Great Escape prisoners of Stalag Luft III disposed of excavated soil — the method used here bears comparison.
Second — the tunnel required wooden support frames installed at 90-centimetre intervals. The prison supply system accounts for every piece of wood entering the facility. Where did the timber come from?
Both questions will be addressed in Evidence File 03.

EVIDENCE FILE 03 — MATERIALS AND SOIL DISPOSAL ANALYSIS
Case Reference: HWP-2024-0118
Evidence Item: EV-03 — Construction materials identification and soil disposal investigation
Prepared By: Dr. Yemi Adebayo, Forensic Investigation Unit
Date: Thursday — 4:45 PM
BACKGROUND
Evidence File 02 established that the tunnel required two things that Daniel Vanek could not simply possess in a maximum security cell — a significant volume of timber for support frames and a method of disposing of approximately 1.24 cubic metres of excavated soil and concrete rubble without detection.
Both questions are answered by the same investigation.
PART ONE — THE TIMBER
Each support frame consisted of three pieces of wood — two uprights and one crosspiece — cut and fitted precisely to the tunnel's dimensions.
Investigators counted 46 frames along the tunnel's 41.3 metre length.
That represents 138 individual pieces of timber — each approximately 60 centimetres long and 4 centimetres wide.
A quantity of timber this significant cannot be smuggled into a maximum security cell in one or two pieces. It had to come from inside the prison — and it had to come gradually.
Identification of timber source:
Laboratory analysis of wood samples taken from three tunnel frames identified the timber as medium-density fibreboard — MDF — a manufactured wood product composed of compressed wood fibres and resin binder.
MDF is not present in any cell furnishing at Hartwell Prison.
It is however the material used for the internal shelving panels of the prison-issue desk units installed in every cell in Cell Block C.
Each desk unit contains six MDF shelf panels — each panel 90 centimetres long, 30 centimetres deep, and 1.8 centimetres thick.
Vanek's desk unit was examined. All six panels were present and appeared intact.
They were not intact.
Each panel had been carefully split along its length — separating the MDF into two thinner layers of approximately 0.9 centimetres each. The outer layer was replaced in the desk unit, maintaining its appearance. The inner layer was cut into support frame components and used in the tunnel.
From outside the desk the shelves appeared completely normal.
Over 14 months Vanek harvested six full desk panels — producing 12 usable layers — and cut them into 138 support components without ever appearing to have modified his cell furniture.
PART TWO — SOIL DISPOSAL
1.24 cubic metres of excavated material — compacted clay, gravel, and concrete rubble — had to go somewhere.
It did not leave through Cell 14 in significant quantities — only trace amounts were found in the cell itself.
Investigators examined the tunnel exit point and the supply corridor shelf unit in detail.
Behind the shelf unit — in the space between the shelf's rear panel and the corridor wall — investigators found a compacted deposit of fine soil and concrete dust approximately 12 centimetres deep across the full width of the shelf base.
This accounted for a portion of the material — but not all of it.
The remaining disposal method was identified through examination of the prison exercise yard.
Exercise yard soil analysis:
Hartwell Prison's exercise yard is a compacted gravel surface — maintained by the prison's facilities team and topped up with fresh gravel annually as part of routine maintenance.
Soil core samples taken from the exercise yard at 10 locations revealed an anomaly in four samples taken from the southwestern corner of the yard — the corner closest to Cell Block C.
These four samples showed a distinct layer of reddish-brown clay — identical in composition to the tunnel excavation material — embedded approximately 8 to 12 centimetres below the current gravel surface.
The layer was not present in samples from any other part of the yard.
The disposal method:
Vanek transported excavated material from the tunnel through Cell 14 in the cloth bags identified in Evidence File 01 — carrying small quantities at a time concealed beneath his prison clothing.
During exercise yard time — one hour per day — he deposited the material in the southwestern corner and worked it into the existing gravel surface with his feet during normal walking movement.
Over 14 months — at an estimated disposal rate of 0.3 to 0.5 litres per exercise session — the volume is consistent with the total excavated material.
The annual gravel top-up — applied in March each year — covered the deposited material and reset the surface appearance.
By the time investigators took core samples the most recent clay layer was 8 centimetres below the current surface — consistent with having been deposited before the most recent annual gravel top-up.
ONE DETAIL THAT DID NOT FIT
Investigators noted one inconsistency in the disposal timeline.
The tunnel's estimated excavation rate — 18 to 29 hours per month — and the estimated disposal rate — 0.3 to 0.5 litres per exercise session — are consistent with each other for most of the 14-month period.
However soil core analysis suggests a significantly higher volume of material was deposited in the exercise yard during one specific six-week period — approximately eight months before the escape.
During that same six-week period Hartwell Prison records show that Cell Block C's exercise yard sessions were extended from one hour to ninety minutes per day — due to a scheduling change caused by maintenance work on the indoor recreation facility.
The additional thirty minutes per session provided significantly more disposal capacity.
The tunnel's deepest and most difficult section — where it passes beneath the foundations of the cell block perimeter wall — was excavated during that six-week period.
Vanek did not create the opportunity. He recognized it and used it.
YOUR TASK
The materials analysis has established how the tunnel was built and how the excavated material was disposed of — gradually, invisibly, exploiting every available opportunity over 14 months.
Split desk panels provided 138 timber support components without any apparent modification to cell furniture. Exercise yard time provided daily disposal capacity that scaled with available time. The annual gravel top-up erased the surface evidence once per year.
Research how the Stalag Luft III prisoners disposed of tunnel soil during the Great Escape — the method Vanek used follows the same principle. Consider what the six-week exercise yard extension tells you about how Vanek planned — not just the engineering but the timing.
One question remains unanswered — and it is the most important one.
The tunnel required excavation work inside a maximum security cell. Concrete cutting. Repetitive digging. Material movement. Over 14 months.
How did Vanek work without being heard — and Evidence File 04 will reveal that the answer involves someone who had no idea they were helping him.
EVIDENCE FILE 04 +
EVIDENCE FILE 04 — ACOUSTIC ANALYSIS AND SENSOR INVESTIGATION
Case Reference: HWP-2024-0118
Evidence Item: EV-04 — Sound environment analysis and alarm system review
Prepared By: Dr. Yemi Adebayo, Forensic Investigation Unit / Dr. Clare Finch, Acoustic Engineer
Date: Friday — 10:00 AM
BACKGROUND
The tunnel required 250 to 400 hours of excavation work — concrete cutting, digging, material movement — conducted inside a maximum security prison cell where guards patrol every 30 minutes and the cell block is monitored by both camera and acoustic sensors.
Two questions required answers:
How did Vanek work without triggering the acoustic sensors that monitor Cell Block C for unusual sounds?
How did he work without being heard during guard patrols?
The answers required both an acoustic engineering analysis of the cell block environment and a detailed review of the prison's sensor and patrol records.
PART ONE — THE ACOUSTIC SENSORS
Cell Block C is monitored by an acoustic sensor network — 14 sensors mounted at ceiling level throughout the block. The sensors are designed to detect unusual sounds — fighting, tool use, structural interference — and alert the duty officer automatically.
Dr. Clare Finch reviewed the sensor specifications and conducted acoustic testing in Cell 14 and the surrounding block.
Sensor threshold:
The acoustic sensors activate when sustained sound above 62 decibels is detected for more than 3 consecutive seconds within a 4-metre detection radius.
For reference:
Normal conversation: approximately 60 decibels
Scraping metal on concrete: approximately 72 to 85 decibels
Concrete cutting with an improvised steel tool: approximately 68 to 78 decibels
The cutting and digging work required to excavate the tunnel would — under normal conditions — have triggered the acoustic sensors repeatedly.
But the sensors were not triggered once during 14 months.
Acoustic testing findings:
Dr. Finch conducted controlled acoustic tests in Cell 14 — reproducing the sounds of concrete scraping and soil digging at the estimated working intensity.
When Cell 14's ventilation fan was running — the standard forced-air ventilation system installed throughout Cell Block C — the ambient noise level inside the cell measured 58 to 64 decibels.
With the ventilation fan running and the cell door closed the scraping and digging sounds produced at floor level — where the tunnel access was located — measured 59 to 63 decibels at the sensor position in the corridor outside.
Below the 62-decibel threshold for sustained activation.
The ventilation system — a standard prison infrastructure component — provided sufficient ambient noise to mask the tunnel excavation sounds from the corridor sensors when work was conducted at floor level with the cell door closed.
Dr. Finch noted one additional factor.
The sensor in Cell Block C's corridor — the one closest to Cell 14 — had been logging intermittent low-level alerts since month 3 of Vanek's occupation. Each alert lasted less than 3 seconds — below the sustained threshold for duty officer notification.
Over 14 months the sensor logged 847 sub-threshold alerts from the Cell 14 direction.
No alert ever reached the duty officer. The system was working exactly as designed — filtering out brief sounds below threshold.
Vanek had learned the sensor threshold and worked within it — pausing every 2 to 3 seconds to stay below the sustained detection window.
PART TWO — THE GUARD PATROLS
Cell Block C guards conduct visual patrols every 30 minutes — walking the corridor and checking each cell through the observation window.
Vanek's working window during each 30-minute patrol cycle was approximately 26 minutes — accounting for the time between a guard passing Cell 14 and the sound of approaching footsteps from the corridor end giving advance warning.
Prison shoe soles on the concrete corridor floor are audible from approximately 15 metres away under normal cell block conditions.
Cell 14 is located 22 metres from the Cell Block C entrance — providing approximately 8 to 10 seconds of advance warning before a guard reached observation window distance.
Sufficient time to replace the floor panel, move the bed back into position, and be in the bed under the blanket before the guard looked through the window.
PART THREE — THE WEEKLY NOISE WINDOW
The acoustic analysis produced one finding that answered the most important question — how Vanek cut through the concrete floor in the first place.
Concrete cutting — even with an improvised tool — produces impact sounds significantly louder than scraping and digging. The initial floor penetration and the cutting of the 60-centimetre by 45-centimetre access panel would have required sustained effort well above the sensor threshold under any masking condition.
Dr. Finch identified one recurring period when this work would have been possible.
Every Thursday evening between 7:30 PM and 9:00 PM Cell Block C hosts a scheduled communal television session in the recreation room at the block's far end. Attendance is voluntary. Noise levels during the session — measured by Dr. Finch — reach 74 to 82 decibels at the corridor sensor locations throughout the block.
Well above the threshold — but the sensors are programmed to automatically suppress alerts during scheduled communal activity periods to avoid false positives from legitimate noise.
During the Thursday evening television session the acoustic sensors in Cell Block C were effectively blind.
Vanek conducted his concrete cutting work exclusively on Thursday evenings.
Prison attendance records show that Daniel Vanek never once attended the Thursday evening television session during 14 months of occupation.
He was always in his cell.
THE SHELF UNIT
There is one detail that connects the acoustic analysis to a specific person.
The Thursday evening television session runs from 7:30 PM to 9:00 PM.
Prison supply records show that Officer Patricia Nolan — assigned to Cell Block C supply management — conducted her weekly supply corridor stock check every Thursday evening between 7:45 PM and 8:30 PM.
Her route took her through the supply corridor past the shelf unit above the tunnel exit point.
During her stock check Officer Nolan moved the shelf unit 18 inches from the wall to retrieve supply forms stored behind it — a procedural shortcut she had adopted because the forms were easier to access from behind the shelf than from the front.
She replaced the shelf each week — but not always in precisely the same position.
Over 14 months the shelf unit had migrated an average of 3 centimetres per week from its original bolted position — the repeated movement gradually working the rear left bolt loose over time.
By month 11 the rear left bolt was loose enough for Vanek to remove it from below with his improvised tool during Thursday evening sessions — giving him access to the supply corridor exit point.
Officer Nolan's weekly shelf movement — a minor procedural shortcut taken every Thursday for convenience — had over 14 months created the exit mechanism for the tunnel.
She had no idea.
YOUR TASK
The acoustic analysis has revealed how Vanek worked undetected for 14 months.
The ventilation fan masked routine excavation sounds below the sensor threshold. The 30-minute patrol cycle gave him a reliable working window. The Thursday evening television session — during which acoustic sensors were suppressed — provided the only window for high-impact concrete cutting work.
And Officer Patricia Nolan's weekly shelf movement — entirely innocent, entirely routine, taken for convenience — gradually loosened the bolt that became the tunnel's exit mechanism.
Consider what the acoustic evidence tells you about how Vanek planned. He did not fight the prison's systems. He understood them — the sensor threshold, the patrol timing, the Thursday suppression window — and worked within them.
What does Officer Nolan's role tell you about the difference between an accomplice and an unwitting enabler? And what single piece of evidence would confirm that Vanek knew about her Thursday routine before he chose the exit point for his tunnel?
That confirmation is waiting in Evidence File 05.
EVIDENCE FILE 05 +
EVIDENCE FILE 05 — RECORDS ANALYSIS AND TIMELINE RECONSTRUCTION
Case Reference: HWP-2024-0118
Evidence Item: EV-05 — Prison records, behavioral analysis, and timeline reconstruction
Prepared By: Dr. Yemi Adebayo, Forensic Investigation Unit
Date: Friday — 3:30 PM
BACKGROUND
Evidence File 04 established that Officer Patricia Nolan's weekly Thursday shelf movement — entirely innocent and entirely routine — had over 14 months created the exit mechanism for Daniel Vanek's tunnel.
One question remained.
Did Vanek choose the supply corridor exit point because it was the most structurally convenient — or because he already knew about Officer Nolan's Thursday routine before he began excavating?
If he chose the exit point first and discovered the shelf movement later — it was coincidence exploited.
If he knew about the routine before he chose the exit point — the tunnel was targeted from the beginning.
The difference matters. One is opportunism. The other is something considerably more calculated.
Dr. Adebayo requested full access to Hartwell Prison's records for the 14 months of Vanek's occupation — visitor logs, library records, medical appointments, work assignments, behavioral reports, and staff rotation schedules.
FINDING 1 — LIBRARY RECORDS
Daniel Vanek requested and borrowed the following titles from the prison library during his 14-month occupation:
Month 1: Introduction to Structural Engineering — a general engineering textbook
Month 1: The Great Escape — Paul Brickhill — the account of the Stalag Luft III tunnel escape
Month 2: Soil Mechanics — Principles and Practice
Month 3: Understanding Acoustics — an undergraduate physics textbook
Month 4: Practical Woodworking
Month 5: Navigation for Beginners — covering compass use and bearing calculation
Month 6 onward: Fiction only — no further technical titles requested
Dr. Adebayo noted that the technical reading stopped in Month 6 — after which Vanek borrowed only novels.
"He had learned what he needed. After Month 6 he stopped leaving a paper trail."
FINDING 2 — WORK ASSIGNMENT
For the first three months of his occupation Vanek was assigned to the prison laundry — standard new prisoner work placement.
In Month 4 he applied for a transfer to the prison facilities maintenance team — citing a background in construction work prior to his conviction.
The application was approved.
His work assignment for Months 4 through 14 was the facilities maintenance team — responsible for minor repairs, cleaning, and supply management across the prison.
His assigned area: Cell Block C and the adjacent supply corridor.
In this role Vanek had legitimate supervised access to the supply corridor on Wednesday afternoons — conducting routine maintenance checks alongside a supervising officer.
Prison maintenance logs show that Vanek consistently requested to check the supply corridor's shelf storage units as part of his Wednesday rounds — logging minor observations including a note in Month 6 that the rear left bolt of the large shelf unit appeared to be showing early signs of loosening.
He logged it. He did not fix it.
The supervising officer signed off the log without action — a minor loose bolt in a supply corridor shelf was not a priority repair.
Vanek identified the loose bolt in Month 6. The tunnel was begun in Month 3.
He had targeted the shelf unit before the bolt was loose — and then documented its loosening through official channels to create a legitimate record of his awareness of it.
FINDING 3 — STAFF ROTATION RECORDS
Officer Patricia Nolan was assigned to Cell Block C supply management from the beginning of her posting — four months before Vanek's arrival.
Her Thursday evening supply corridor stock check was a documented routine — recorded in the Cell Block C duty log every Thursday for the duration of her posting.
The duty log is accessible to facilities maintenance team members conducting their Wednesday rounds — as it is kept in the supply corridor administrative folder that Vanek routinely handled during his Wednesday maintenance checks.
Vanek had access to Nolan's documented Thursday routine from Month 4 onward.
The tunnel's exit point — positioned precisely beneath the shelf unit that Nolan moved every Thursday — was chosen in Month 3.
One month before Vanek had official access to the duty log.
FINDING 4 — VISITOR RECORDS
Daniel Vanek received one visitor during his 14-month occupation.
His brother — Stefan Vanek — visited in Month 2 for a standard 45-minute supervised visit.
The visit was recorded and partially monitored in accordance with standard procedure. The monitoring transcript shows a largely personal conversation — family matters, health, finances.
One exchange was noted by the monitoring officer as unremarkable at the time:
Stefan Vanek mentioned he had recently started a new job — "logistics, supply chain, warehouse work."
Daniel Vanek responded: "That's good. You always knew how systems worked. How people move through them."
The conversation moved on.
Dr. Adebayo noted that Stefan Vanek's employment history — checked as part of the investigation — shows no record of logistics or warehouse work at any point before or after the visit.
FINDING 5 — THE COMPASS
A standard magnetic compass was not found in Cell 14 during the forensic search.
A compass is not a prohibited item at Hartwell Prison — it is available through the prison canteen as part of a geography education pack sold to prisoners enrolled in distance learning courses.
Daniel Vanek enrolled in a GCSE Geography distance learning course in Month 2 of his occupation.
He withdrew from the course in Month 4 — after the standard 12-week enrollment period during which the course materials — including a compass — were legitimately his to keep.
His course withdrawal was recorded as voluntary. His course materials were not recalled.
The compass was never found.
It left with him.
FINAL TIMELINE — RECONSTRUCTED
Month 1
Arrives at Hartwell Prison. Immediately begins technical reading — structural engineering, soil mechanics, acoustics. Borrows The Great Escape from the prison library.
Month 2
Brother Stefan visits. Exchange about systems and logistics recorded by monitoring officer as unremarkable. Vanek enrolls in GCSE Geography distance learning — legitimately obtaining a magnetic compass as part of the course materials.
Month 3
Tunnel excavation begins. The exit point — beneath the supply corridor shelf unit — is already chosen before Vanek has official access to staff duty logs.
Month 4
Transfers to facilities maintenance team. Gains legitimate supervised access to the supply corridor. First access to the Cell Block C duty log — which documents Officer Nolan's Thursday evening routine in writing. Withdraws from geography course. Retains the compass.
Month 5
Stops borrowing technical titles entirely. Switches to fiction only. The learning phase is complete. The execution phase is underway.
Month 6
During a routine Wednesday maintenance check Vanek officially logs the loose bolt on the supply corridor shelf unit. He does not repair it.
Month 8
The indoor recreation facility closes for maintenance. Exercise yard sessions extended from 60 to 90 minutes daily for six weeks. Vanek uses the additional yard time to accelerate soil disposal — excavating the tunnel's deepest and most difficult section beneath the cell block perimeter wall during this window.
Month 11
The shelf unit's rear left bolt — loosened progressively by Officer Nolan's weekly Thursday movement over 14 months — is now sufficiently loose for Vanek to remove it from below using his improvised tool during Thursday evening sessions.
Month 14 — Thursday evening
Acoustic sensors suppressed for the scheduled television session. Officer Nolan completes her shelf stock check and leaves the supply corridor at approximately 8:30 PM. At some point between 8:30 PM and 11:00 PM Daniel Vanek descends through the Cell 14 floor panel, crawls 41.3 metres through the tunnel, surfaces beneath the shelf unit in the supply corridor, crosses the service yard, and exits through the drainage channel beneath the outer perimeter wall.
At 11:00 PM the duty guard conducts the visual check through Cell 14's observation window. The dummy is in the bed. The check is marked clear.
At 6:03 AM Officer Costa opens Cell 14 for the morning headcount.
The cell is empty.
YOUR TASK
You now have all five Evidence Files.
The forensic examination revealed the tunnel entrance. The engineering analysis revealed the tunnel itself. The materials analysis revealed how it was built and how the soil was disposed of. The acoustic analysis revealed how Vanek worked undetected. And the records analysis has revealed the full scope of what was planned — and when.
Using evidence from all five files — reconstruct Daniel Vanek's escape. Was Officer Nolan an accomplice — or an unwitting enabler? What does the timeline tell you about when Vanek chose his exit point relative to when he gained official knowledge of Nolan's routine? And what did the brother's visit in Month 2 actually establish?
The escape required engineering knowledge, acoustic awareness, materials improvisation, soil disposal logistics, compass navigation, and fourteen months of disciplined patience.
Build your case. The records have preserved everything. Can you piece it together — and determine exactly how much of this was planned before Daniel Vanek spent his first night in Cell 14?
