According to a preliminary investigation, a Hawthorne police officer was on patrol when a woman driving a car pulled up and said she was being followed. The officer told the driver to pull up in front of him and he would investigate, sheriff’s officials said.

Investigators say a white Cadillac then pulled up next to the officer and the woman.

“The right front passenger of the suspect vehicle got out and began firing at the driver and passenger in front of the police officer. The police officer immediately got out. And an officer-involved shooting occurred,” Los Angeles County sheriff’s Lt. Dave Coleman said.

A passenger in the front seat of the shooter’s car was killed, and the male driver and a man in the rear seat were arrested.

A 12-year-old boy was in the victim’s car.

“The child ran to a different location, and being treated now at a local hospital for gun shot wounds,” Coleman said.
