Bexar County deputies are looking for a driver who fled on foot after running a red light and striking two other cars Friday morning.
Two pickups were stopped next to each other at a red light on Highway 87 near FM 1516 in China Grove, deputies said.
A silver Dodge Ram pickup did not stop, striking one pickup from behind and sideswiping another, according to deputies.
The driver who caused the crash, a New Mexico man, fled on foot before deputies arrived.
First responders took another driver with serious injuries to the hospital.
The case was ongoing Friday.
