DPS tells KXAN Trooper Chad Walker is in a critical condition in a Waco hospital after the shooting outside Mexia, northeast of Waco, at about 8 p.m. on Friday night.

Walker had stopped to help a driver in a disabled vehicle on FM 2838, when the driver allegedly got out of the vehicle and shot him multiple times.

DeArthur Pinson, Jr. has been identified as the suspect who allegedly shot at Walker. DPS says Pinson, 36, was found dead at a residence on Highway 84, which is west of Mexia, Saturday evening with what police believe is a self-inflicted gunshot wound.

DPS issued a warning that Pinson was wanted and instructed the public to call 911 if anyone had information on where he might be.

Early on Saturday morning, DPS issued a Blue Alert for Pinson. Blue Alerts are issued for people who are accused of killing or seriously injuring a law enforcement officer.
