The Los Angeles County Sheriff's Department responded to a call in the 3700 block of Sierra Highway on Monday around 4:45 p.m. According to LASD, a woman – who was driving a gray compact car – was being chased by her ex-boyfriend, a 26-year-old man who was driving a white Chrysler sedan.
The tense chase led to the cars hitting each other at least once. Both cars eventually stopped in the middle of Sierra Highway near Avenue S. LASD was told the ex-boyfriend tried to break into the woman's car as she was calling for help from family members who had called 9-1-1 for her.
The woman's father pulled up to the scene in a white Ford Ranger pickup truck, got out of the vehicle, and shot the ex-boyfriend in the head, ultimately killing him.
The dad, later identified as Jose Mendoza, took off from the scene and remains on the run. LASD warned the public to not approach Mendoza, who is believed to still be armed after the deadly shooting.
Mendoza is believed to be from Littlerock, a neighborhood just southeast of Palmdale.
On Thursday, it was revealed Mendoza swung by a police station after the deadly shooting to turn himself in. However, he left the building after briefly waiting inside.
Anyone with information on Mendoza is asked to call LASD's homicide bureau at 323-890-5500.
