Huntington Beach police are looking for a hit-and-run driver they believe was involved in an early-morning crash that killed a pedestrian from Costa Mesa.

The Orange County coroner’s office identified the victim as 28-year-old Matthew Aguilar.

Police said Aguilar was in the middle of Pacific Coast Highway near Brookhurst Street in Huntington Beach when a Cadillac sedan hit him at about 4:30 a.m.

After the initial crash, a second car struck Aguilar, according to police.

“The second vehicle and its driver fled the scene and has not been identified,” police said in a news release. “The vehicle would likely have damage to the front end and undercarriage.”

The Cadillac’s driver, a 55-year-old man from Huntington Beach, was uninjured and stayed at the scene where police interviewed and released him.

The Cadillac was traveling northbound on Pacific Coast Highway when it struck Aguilar, who was lying in the roadway when officers and paramedics responded, police said.

Paramedics pronounced him dead at the scene.
