Level Two

The case file

Someone broke into a car in the parking garage overnight. The logs below are all verified -- the order has to be reconstructed. What happened last?

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

The clues

1. The elevator log shows the elevator call button being pressed at 11:42 PM, after the exit barrier lifting.
2. The door sensor log shows the stairwell door sensor tripping at 11:15 PM, before the exit barrier lifting.
3. The alarm log shows the car alarm sounding at 11:01 PM, before the level-two camera flagging motion.
4. The radio log shows the attendant's radio check being logged at 11:52 PM, before the level-two camera flagging motion.

Who did it?

1. the attendant's radio check being logged
2. the level-two camera flagging motion
3. the stairwell door sensor tripping
4. the exit barrier lifting
