Teen shot by police officer at McDonald's remains on life support as questions grow over incident

Erik Cantu, the 17-year-old shot by a police officer in a McDonald's parking lot in San Antonio, Texas, remains on life support with more surgeries scheduled, his family said. 

Body camera video shows police officer James Brennand walking toward a parked car on Oct. 2. The officer opens the driver side door and orders Cantu out of the vehicle. Cantu looks surprised and reverses the car. 

Roughly five seconds after opening the door, the officer fires five rounds into the car. He then shoots five more times as the car drives away.
