Witness Accounts at the Loading Dock
A warehouse loading dock reports a stolen pallet of electronics at 0145. Three witnesses give statements. Witness A says she saw a white van leave at 0140 and that the driver wore a red cap. Witness B says the van was silver and left at 0155, and that no one was wearing a cap. Witness C says she heard a engine start around 0145 and saw a van leave but did not note the color or time precisely. The dock camera shows a vehicle leaving at 0142 but the footage is grainy and color cannot be confirmed. The gate log shows a white van entered at 2330 and no exit was recorded. A second gate log entry shows a silver van exited at 0205.
1. Apply Deductive Reasoning: which witness statements are supported, contradicted, or neither by the physical evidence?
Read the worked answer
- Witness A's time (0140) is close to the camera time (0142) and is supported within a few minutes; the color white matches the gate log entry for a white van, though the camera cannot confirm color. Her red-cap detail is unverified by any physical evidence.
- Witness B's time (0155) conflicts with the camera (0142) and with the gate log's 0205 silver exit; the silver van exit at 0205 could match B's color but not B's claimed time. B's statement is partly contradicted.
- Witness C's approximate time (0145) is consistent with the camera (0142) and she makes no color claim, so nothing contradicts her; her statement is neither confirmed nor contradicted on color.
Conclusion: A is best supported on time and plausibly on color; B is contradicted on time; C is consistent but vague.
2. A supervisor concludes the white van is the suspect vehicle. What gaps remain before that conclusion is reliable?
Read the worked answer
The white van entered at 2330 with no recorded exit, which is suspicious but not proof of the theft. The camera confirms a vehicle left at 0142 but cannot confirm color. The silver van's 0205 exit is a competing data point. Before concluding, the supervisor needs: (1) confirmation of the white van's exit time, (2) a check of whether the 0142 vehicle matches the white van's plate or description, and (3) reconciliation of the missing exit entry, which could be a logging error rather than a theft. The conclusion is plausible but not yet reliable because the color link rests on the gate log alone and the exit record is incomplete.
