The Illinois State Police has released the identity of the suspect who shot and wounded a trooper in Staunton Saturday afternoon after an alleged carjacking.

Billy Walker Jr. of Hillsboro, Missouri, was pronounced dead at 4:45 p.m. Saturday by the Macoupin County Coroner. He died from gunshot wounds he received while in a shootout with an officer.

According to the police, Walker, 53, was involved in an alleged carjacking near Sam's Club in Glen Carbon. The suspect allegedly fired shots during the incident, and fled the scene as troopers were arriving. The suspect drove north on Interstate 55 to the Staunton exit. After driving into Staunton, the man drove off the roadway and got the car he was driving stuck in the median near the intersection of Staunton Road and I-55. He then exited the vehicle and fled on foot while a trooper chased him. Police said Walker brandished a handgun and fired at the trooper, who returned fire and shot the suspect.

The 36-year-old trooper, whose identity has not been released, was wounded and was taken to a regional hospital with non-life threatening injuries. He is an 11-year veteran of the state police.

Walker had an outstanding warrant for a probation violation resulting from weapons offenses prior to the Glen Carbon carjacking, according to the state police. He was considered armed and dangerous prior to the incident. The carjacking remains under investigation by the Glen Carbon police department. No further information is being released at this time.
