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.

John Wheeler, the defense contractor who served in three Republican presidential administrations and was found dead in a landfill on New Year's Eve, was acting crazy before his death — and may have tried to burn his neighbor's house down.

The body of John Wheeler, a Vietnam veteran and presidential aide to Ronald Reagan and both Bushes, "was found dead in a landfill a few miles from his New Castle, Delaware home this weekend." Police have ruled it a homicide.
