A young man and woman were found fatally shot at a home in Winnetka late Monday morning, and the shooter is at large.
The call came in just after 11 a.m. from the 7800 block of Oso Avenue, according to Los Angeles Police Department Officer Sal Ramirez.
The woman's mother discovered the bodies, according to officials. She sobbed at the scene, hugging one of her sons.
Police said the victims appeared to be in their mid-20s. They were pronounced dead on scene.
The female victim lived in the home with her mother, according to LAPD Lt. Scott Harrelson.
The male victim was a recent acquaintance of the female victim, police said in a news release. The shooter is believed to know one or both victims.
"Homicide detectives are on scene now and are actively working the investigation," Harrelson said. "But we don't believe anyone in the near area is in any danger."
Neighbors said police had frequently responded to the home. Police said neighbors called 911 after hearing gunshots around 11 a.m.
Witnesses said a man ran north, away from the home. He was described as thin, Hispanic, of medium height, and wearing a white hoodie, green shirt and shorts.
Aerial video from Sky5 showed officers entering a home with Halloween decorations up. One body, underneath a bloodied sheet, was at the rear door to the home.
A woman appeared to be handcuffed in the back of a patrol car. She was later placed on the curb, where a Fire Department official talked to her as she was visibly disturbed.
