A man shot and killed his daughter's ex-boyfriend after he chased her with his car in Palmdale, California on Monday, Nov. 21.

Officers from the Los Angeles County Sheriff's Department reportedly responded to a call in the 3700 block of Sierra Highway at around 4:45 p.m. on Monday, Nov. 21. When the officers responded to the scene, they found 26-year-old Giovannie Gutierrez lying unresponsive in the middle of a highway with a gunshot wound to his head. He was taken to a hospital for treatment. However, despite the efforts, Gutierrez died of his injuries, Law & Crime reported.

According to the authorities, Gutierrez was reportedly chasing his ex-girlfriend's gray compact car with his white Chrysler sedan. During the tense chase, the cars collided with each other at least once. 

After a brief chase, both cars eventually stopped in the middle of Sierra Highway near Avenue S. After stopping, Gutierrez got out of his car and 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.

Following this, the woman's father, later identified as 59-year-old Jose Mendoza, pulled up to the scene in a white Ford Ranger pickup truck. He then got out of the vehicle and approached Gutierrez. Mendoza then pulled out his gun and shot Gutierrez in the head, ultimately killing him, FOX 11 Los Angeles reported.

After shooting Gutierrez dead, Mendoza took off from the scene and remains on the run. Meanwhile, the officers stated that Mendoza is believed to be armed and warned the public to not approach him.

Mendoza is believed to be from Littlerock, about 10 miles from Palmdale in northeast Los Angeles County. He is described as Hispanic with black hair and brown eyes, with a height of 5-foot-6 and a weight of 140 pounds.

On Thursday, Nov. 24, Mendoza reportedly swung by a police station to turn himself in. However, he later left the building after briefly waiting inside and is on the run.

Investigators are asking the public for help in locating Mendoza.
