The Impossible Drive

The case file

Between 5:15 PM and 5:40 PM, the hallway camera caught motion near the break room -- and a vending machine was smashed open. Four people were nearby that evening. Whose alibi falls apart?

The rule: All four findings come from verified records -- logs, cameras, receipts. Exactly one suspect's story contradicts the evidence.

The clues

1. Silas Reed: A camera at riverside park recorded Silas Reed at 5:04 PM. The toll transponder on Silas Reed's car pinged at river toll plaza at 5:51 PM.
2. Sam Okafor: Phone tower records place Sam Okafor near river toll plaza at 5:06 PM. The keycard log shows Sam Okafor badging into the office at 5:42 PM.
3. Lena Brooks: A camera at the break room recorded Lena Brooks at 5:24 PM. A camera at the office recorded Lena Brooks at 5:48 PM.
4. Theo Marsh: A camera at riverside park recorded Theo Marsh at 5:07 PM. The register tape shows Theo Marsh ringing up a sale at the mall at 5:54 PM.

Who did it?

1. Silas Reed
2. Theo Marsh
3. Lena Brooks
4. Sam Okafor
