Los Angeles detectives are investigating after a male driver was found shot to death and a female passenger sustained serious injuries inside a car on Thursday.

Authorities were called to the 1600 block of Van Ness Avenue around 12:45 a.m. after receiving reports of a shooting.

There, they discovered a car with a man and woman inside suffering from multiple gunshot wounds, along with two small uninjured children, the Los Angeles Police Department said.

The children were both under the age of four, Capt. David Kowalski said during a press conference.

The man was pronounced dead at the scene and the woman was transported to the hospital in unknown condition, according to the LAPD.

She was treated and released from the hospital later that day, police said.

The shooter is described as a 20 to 25-year-old man last seen wearing a white shirt and running south on Van Ness Avenue, Kowalski said.

“We challenge the community to come forward with information that may help solve this murder,” said Kowalski. “We have no known motive. This man’s family needs your help and we need your help in solving it.”

Anyone with information about this shooting is asked to call the Los Angeles Police Department at 213-382-9470.
