One person was killed and three were injured in a shooting in Panorama City Wednesday afternoon, officials said.

Just before 2:30 p.m., police responded to reports of a 20-year-old man who was suffering from a gunshot wound, as well as additional victims, according to Officer Tony Im of the Los Angeles Police Department.

The LAPD said in a press release later Wednesday that the initial call was for a traffic collision, which was then updated to a shooting, and when officers arrived, they found “four victims suffering from multiple gunshot wounds.”

On Thursday, police announced they had discovered anther victim, a man who was taken to a local hospital and is in stable condition.

The Los Angeles Fire Department also responded to the reported shooting near Parthenia Street and Tobias Avenue for a reported five patients, though the LAPD later put the total number at four patients.

“The Los Angeles Fire Department responded and pronounced one male victim deceased at scene. A second male suspect was transported to a local hospital in stable condition. A third male victim was transported to a local hospital in unknown condition. A fourth male victim was treated at the scene,” the release said.

As of Thursday, both of these victims who were taken to the hospital are in stable condition, police said.

The man who died was identified by police as 37-year-old Jonathan Santillano of Sylmar.

Police later determined that three vehicles were involved in a crash, and while the participants were exchanging information, an “unknown suspect approached the group and began shooting at them,” police said.

At about 3:30 p.m., police said the suspected shooter was last seen heading south on Van Nuys Boulevard and provided a description of a man about 20 years old in a new BMW. But by Wednesday night, police said they had no suspect information to release beyond that he had fled on foot in “an unknown direction.”

Anyone with information is asked to call Detective Steve Castro at 818-374-3247.
