A San Diego maintenance worker is on the run after police say he repeatedly ran over his estranged wife with his pickup truck, killing her.
Police believe the suspect, 37-year-old Cesar Castillo, may have fled to Mexico.
Witnesses told police they heard screaming before seeing a white pickup truck hit a woman in Chula Vista, California, just before 7 p.m. Friday. The driver then circled back and struck her again, according to Chula Vista Police Sgt. Rustin Rea.
Police said the woman, who has not been identified, died at the scene from head and internal injuries.
A neighbor told NBC 7 he walked out of his house as soon as he heard the truck crash through a fence in a yard. He came out in time to spot the vehicle driving up on the sidewalk and away.
"I called 911 as soon as I saw that," he said. "I wish I had taken video tape or pictures or something. It was brutal."
Investigators believe Castillo intentionally ran over his estranged wife, who was standing in a front yard. The truck also hit two fences and a vehicle in the yards.
"I feel bad that it happened, especially after Thanksgiving, and it was horrific," the neighbor said.
The suspect is employed as a maintenance worker in the Mission Bay area, according to police officials.
Police say Castillo is driving a white 1998 Chevy Silverardo with California license plate 6H89420 and right front-end damage.
Police called in a helicopter to help with the search Friday night. Anyone with information on Castillo's whereabouts is asked to call them at 619-585-5665.
