The Night Log

The case file

Someone broke into the warehouse last night. The logs below are all verified -- the order has to be reconstructed. What happened first?

The rule: Every finding below comes from a verified log. Reconstruct the order of events.

The clues

1. The sensor log shows the storage-room motion sensor firing at 2:31 AM, after the hallway camera flagging motion.
2. The floodlight log shows the loading-dock floodlight switching on at 2:05 AM, after the alarm tripping.
3. The keycard log shows the keycard reader logging an entry at 2:18 AM, before the hallway camera flagging motion.
4. The phone log shows the 911 call being placed at 1:19 AM, after the alarm tripping.

Who did it?

1. the 911 call being placed
2. the keycard reader logging an entry
3. the loading-dock floodlight switching on
4. the alarm tripping
