A conflict between two motorists apparently escalated into a fatal shooting and collision early Sunday morning in West Covina, police said.

Officers responding shortly before 1 a.m. at the 100 block of South Glendora Avenue found a gunshot victim dead in the driver's seat of a vehicle that had crashed into a pole.

Homicide investigators with the West Covina Police Department said the victim was a man in his 20s.

"It appears there was a conflict between the occupants of two different vehicles, which led to the shooting," Lt. Travis Tibbetts said. "The suspect vehicle fled the area after the shooting and at this point is only described as a sedan."

Detectives asked anyone with information to call the West Covina Police tip line at 626-939-8688.
