NASCAR’s star Bobby East has died after reportedly being stabbed at a gas station. 

Police confirm that the deceased was 37 years old and died in California on the 13th of July.

That evening, officers responded to the 76 gas station in Westminster, Calif., about 30 miles south of Los Angeles, to investigate a report of a stabbing, according to a press release from the Westminster Police Department Detectives. Cops found East on the ground, suffering from a serious stab wound to the chest are. The officers attempted to save his life, but East was too weak to move. Paramedics were called and transported him to the local trauma center where he died.

Unknown motives for the attack remain. A murder suspect emerged two days later. Trent William Millsap—a 27-year-old homeless man known to frequent the area, according to local authorities—was arrested in nearby Anaheim, police confirmed in the press release. The press release stated that the West County SWAT Team was asked to serve his warrant due to the violence he displayed.
