Four Burglaries at Maple Ridge: Reading a Pattern Before Naming a Suspect
Over nine days, four burglaries are reported at Maple Ridge Apartments, a 60-unit building with one keypad-entry front lobby, a camera covering only that lobby, and an unmonitored rear stairwell connecting the ground-floor parking garage to each floor's exterior balcony walkway.
The reports share these features: all four units are on the second floor; all four occurred on weekdays between 09:00 and 11:30; entry was made by prying a sliding balcony door; taken were a laptop, two game consoles, and prescription medication; nothing was taken from living rooms visible through the front windows; front doors were locked and undamaged.
The lobby camera shows no unfamiliar faces during the four time windows. Three victims work weekday day shifts. The fourth is a retired man who was home during two of the burglaries but heard nothing.
The property manager says the keypad code was changed after the second burglary, and that a contractor replaced third-floor balcony railings during the same period.
1. Which feature of these reports is least consistent with a stranger forcing a ground-level balcony door, and what does the pattern point toward instead?
Read the worked answer
The least consistent feature is the combination of second-floor balconies, weekday-morning timing, and a resident who was home and heard nothing.
A stranger working from the ground would need a ladder, which is conspicuous in daylight in a parking area and leaves marks below the balcony. Nothing in the reports describes that. A pry on a second-floor balcony door is better explained by access along the balcony walkway from the unmonitored rear stairwell - which requires nothing more than walking up.
The timing points the same way. Four burglaries inside a two-and-a-half-hour weekday window is not random; it is a schedule. Someone selected units whose occupants were predictably away, and the retired man hearing nothing during two of them suggests the entry was quiet and unhurried - behavior consistent with someone who knew the building and expected not to be interrupted.
The front-door detail supports this: no forced front doors and nothing taken from rooms visible through front windows means the offender avoided the side of the building with a camera.
2. Name the single record you would pull next and explain what result would support the insider hypothesis and what result would weaken it.
Read the worked answer
Pull the contractor's work log and site sign-in for the nine-day period, cross-referenced against the keypad or stairwell access records for the four time windows.
Why this record first: it is the only one that can place a non-resident inside the building legitimately, on weekdays, during business hours, with a reason to be near third-floor balconies - and third-floor railing work means ladders and staging that reach the second-floor walkway. It is also a small, finite list, unlike the resident roster.
Supporting result: the same worker or crew signed in on all four burglary dates, with entry times falling inside the 09:00–11:30 windows. That is a coincidence that needs explaining.
Weakening result: no contractor on site during one or more of the windows, or the work order showing the railing job confined to a different elevation. That does not exonerate the building's residents or staff; it removes one candidate and shifts attention to the keypad logs and to who knew the code before and after the change.
Either way, the keypad record matters, because the code change after burglary two did not stop burglaries three and four.
3. The property manager asks you to write in your report that "a resident is responsible." What is unsafe about that conclusion, and what can you state instead?
Read the worked answer
It is unsafe because the evidence is consistent with, not probative of, a resident. The same facts fit a contractor, a staff member, a former tenant who kept the old code, or a non-resident who tailgated through the lobby and used the rear stairwell. "A resident is responsible" also names a category of person without identifying one, which in a report reads as an accusation against sixty households.
A second problem: the lobby camera showing no unfamiliar faces is not evidence of an insider. It is evidence that the camera covers only the lobby. Anyone using the garage or the rear stairwell never appears on it.
What you can state:
"The four incidents share a consistent time window, floor, entry method, and property profile. Entry was not made through the front door, and the lobby camera did not record any of the incidents. Investigative steps include the contractor work log for the period and the keypad and stairwell access records."
That records the pattern, the limits of the camera, and the next step - without naming a suspect class the evidence cannot support.
