MONTEBELLO >> A teenage girl remained hospitalized in critical condition on Friday, two days after she was shot by her neighbor in what was believed to be an accidental shooting at an apartment complex, police said.

The suspected accidental shooting took place shorty after 4 p.m. on Wednesday in the 200 block of North 6th Street, Montebello police Lt. Larry Jackson said.

Police responded to reports of a shooting and encountered a teenage girl suffering from a gunshot wound, he said.

“Preliminary investigation revealed the neighbor was manipulating a firearm in his apartment,” the lieutenant said. The handgun went off, sending a bullet through the wall separating the apartments, and striking the girl in the abdomen.

Rescuers took the wounded teen to a hospital, where she was listed in critical condition after undergoing emergency surgery, Jackson said.

The neighbor, a man, was not arrested as the investigation continued, he said. The man attempted to help the injured girl and called 911 immediately after the shooting.

Once complete, detectives will turn over their findings to the Los Angeles County District Attorney’s Office for consideration of charges.
