Two Places at Once

The case file

Between 6:30 PM and 7:00 PM, the stand's motion sensor tripped -- and a cash box went missing from the concession stand. 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. Peter Aldis: A camera at north garage recorded Peter Aldis at 6:26 PM. Phone tower records place Peter Aldis near riverside park at 7:06 PM.
2. Tessa Quinn: The shift log shows Tessa Quinn clocked in at the office at 7:02 PM. Phone tower records place Tessa Quinn near riverside park at 7:10 PM.
3. Derek Sloane: The register tape shows Derek Sloane ringing up a sale at downtown at 6:15 PM. The toll transponder on Derek Sloane's car pinged at river toll plaza at 7:03 PM.
4. June Park: A camera at north garage recorded June Park at 6:29 PM. The shift log shows June Park clocked in at downtown at 7:03 PM.

Who did it?

1. Peter Aldis
2. Derek Sloane
3. June Park
4. Tessa Quinn
