San Antonio Officer James Brennand was fired after shooting Erik Cantu, 17, on Oct. 2 in a McDonald's parking lot, police training commander Alyssa Campos said in a video statement released Wednesday, which included the officer's bodycam footage of the incident."While Sunday's shooting of an unarmed teenager by a then-San Antonio Police officer remains under investigation, the facts and evidence we have received so far led us to reject the charges against Erik Cantu for further investigation," Bexar County District Attorney Joe Gonzales said.Brennand, who had been on the force for less than one year, violated his training and police procedures after approaching the car, Campos said.Cantu, in the officer's body camera video, looks toward Brennand while holding a hamburger, then backs the car away, striking the officer with the open door.Gonzales, the district attorney, said no decision had been made on whether to pursue charges against Brennand, pending the outcome of a police investigation into the shooting."
