Investigators say a motorist who died after a shootout with police along a busy Missouri interstate had threatened to kill co-workers and a relative, and was wearing a bulletproof vest.

Jefferson County Sheriff Dave Marshak on Monday identified the driver as 31-year-old Jerrod Kershaw of Pacific, Missouri. He says Kershaw also had several weapons in the vehicle.

Marshak says the incident started when Kershaw wrecked his vehicle about 9 a.m. Monday near the intersection of Interstate 55 and Interstate 270 in neighboring St. Louis County. Kershaw then carjacked a vehicle when a man stopped to help him.

Moments later, police received two calls. Marshak says one was from Kershaw’s mother, who said her son was heading to a nearby city to kill a relative and himself. Another caller said Kershaw made “homicidal and suicidal threats” against his workplace, which was not disclosed.

Police used stop strips to disable his vehicle. Marshak says Kershaw shot at police, and officers returned fire.

Kershaw was later found dead in the car. Police haven’t released a cause of death.
