A man apparently stole a gun and car from his girlfriend Monday night before he fatally shot his mother and stepfather in a St. Louis home, police said.

The man then shot and killed himself, according to police.

The body of Kenneth Murray, 44, was found along with those of his mother, Eunice Cain, 60, and his stepfather, Reginald Wilkes, 59, about 3:50 a.m. Tuesday after police were called the couple’s home in the 5500 block of Era Avenue. The home, near Goodfellow Boulevard and West Florissant Avenue, is in the Walnut Park West neighborhood.

The victims were pronounced dead at the scene. Police say they found two guns at the scene.

Police believe Murray stole a gun and car from his girlfriend the night before in Hanley Hills.

St. Louis County police say they went to a domestic violence call in the 7400 block of Balfour Drive in Hanley Hills about 9:30 p.m. Monday. They met with Murray’s girlfriend there, who said Murray had come to her home and the two had fought. He stole her handgun and car and fled, she told police.

Murray, of the 4200 block of Penrose Street, was listed that night as wanted for stealing a firearm, domestic peace disturbance and taking a motor vehicle without the owner’s consent.
