Authorities say officers found a backpack with a ski mask and burglary tools in a U-Haul connected to the man suspected of shooting and wounding a San Francisco Bay Area transit officer.

Bay Area Rapid Transit Deputy Police Chief Jeffrey Jennings says the backpack also had a BB gun.

Charles Goetting was also shot Friday when a second Bay Area Rapid Transit officer returned fire. BART police say they later discovered a man's body inside a U-Haul truck that Goetting was pushing.

The vehicle's license plates had been switched. Jennings said the handgun Goetting used was stolen.

Authorities also say Goetting was on probation following drug and burglary convictions.

Goetting was listed in stable condition Friday. The wounded officer was treated and released from a hospital.
