A Bexar County Sheriff's deputy fired on a fleeing suspect in a road rage incident after the suspect rammed his car into the deputy's patrol vehicle early Sunday morning.

The incident began at 5:39 a.m. Sunday when a driver reported a road rage incident near Loop 1604 and Marbach Road on the west side of San Antonio, according to a preliminary report from the Bexar County Sheriff's Office.

The deputy searched for and found the other car involved at a nearby dead end. The suspect turned the vehicle toward the patrol deputy at a high rate of speed, striking the patrol vehicle and the deputy, according to the report.

The deputy used his Taser toward the suspect, but it was ineffective. The deputy then fired his weapon, striking the suspect, the report said.

The suspect fled the location, striking another driver on the road before a second patrol unit found the suspect on the access road of US Highway 90 and Kriewald Road and collided with the suspect's vehicle, ending the pursuit. Both vehicles were left inoperable.

The 17-year-old male suspect was in critical condition at a local hospital Sunday morning. A female passenger also received minor injuries, and the driver of another car he struck also was transported to the hospital.

The deputy involved in the shooting will be placed on temporary administrative duty, pending further investigation.
