Almost everyone who encountered murdered defense contractor John Wheeler in the days before his death says he was acting crazy. New surveillance video doesn't dispute this. Wheeler wanders around a parking garage with one of his shoes in his hand.

The video was taken last Wednesday in a parking garage in Wilmington, Delaware. Wheeler was looking for his car there, and the attendent who spoke to Wheeler in the video said he told her his briefcase had been stolen. She didn't "notice any odor of alcohol," according to the Washington Post.

Wheeler's body was found two days later in a landfill a few miles from his home in New Castle, Delaware. His car was found parked at its usual spot in a different garage near the Amtrak station.
