Bobby East, a three-time US Auto Club (USAC) national champion driver, has died after being stabbed at a Southern California petrol station earlier this week. He was 37.

The Westminster Police Department issued a statement identifying Robert John East of San Dimas as the person stabbed in the chest on Wednesday.

The statement said the stabbing suspect, Trent William Millsap, was shot and killed in Anaheim on Friday as officers tried to arrest him.

Police say they have no motive for the stabbing and the investigation into both deaths is ongoing.

They said they arrived at the gas station shortly before 6pm to find East suffering from a stab wound.

He was taken to University of California, Irvine Medical Center, where he died.

East, whose father was a noted short-track car builder, won USAC’s National Midgets title in 2004 and Silver Crown championships in 2012 and 2013.

He had 56 USAC-sanctioned feature victories, 48 of them in national divisions.

He was just 16 in 2001 when he became the youngest driver to win a feature USAC National Midget race.

He won 15 USAC races in 2004 before dabbling in a short NASCAR career.

He made 11 career starts in what is now NASCAR’s Xfinity Series and had two top-10 finishes in 31 career Truck Series races.

“We extend our deepest and heartfelt condolences to the family and friends of Bobby, a true racer.”

“Very sad to hear of the tragic incident involving Legend USAC driver Bobby East. He was one heck of a wheelman,” tweeted former Truck Series champion Todd Bodine.

Westminster police said Millsap, 27, was on parole for armed robbery and had an outstanding warrant for his arrest for an unrelated parole violation.
