What appears to be a case of road rage has left a man dead. San Antonio Police say it happened near 1604 and O'Connor Road when a vehicle pulled up beside a pickup truck carrying a camper trailer and fired one shot into the driver's window, hitting and killing the driver. The truck kept going until it struck an off-duty police officer's vehicle that was parked at a construction site. A woman who was also in the truck was taken to the hospital with injuries from the wreck. The officer was not in the car at the time his vehicle was hit. Police are continuing to investigate.
