A man who was working as a security guard was fatally shot near a downtown Los Angeles movie set Thursday night.

The shooting occurred in the 1900 block of Bay Street, near Alameda Street, around 11 p.m. when, according to detectives, a man in his 30s was shot in an alley.

An off-duty Los Angeles police officer who was working at the set of a movie being filmed roughly one block away heard the gunshots and called 911, police told KTLA.

The victim was pronounced dead at the scene. Police say the incident was not related to the movie production and did not involve any cast or crew members.

No suspect description was available.

The victim’s family told KTLA he was a security guard who worked in the area. They said the suspect was trying to break into cars when the victim approached the suspect and was shot in the head.

His family identified him as 34-year-old Jairo Ortiz.

Police say a second man was shot in the leg a few blocks north of the initial scene and was driven to a hospital with a non-life-threatening wound.

Detectives are trying to determine if the two shootings are connected.

Anyone with information about the shootings is urged to contact the LAPD tip line at 1-877-527-3247. You can also submit an anonymous tip online.
