Girl, 8, hit by stray bullet in West Los Angeles apartment complex

A girl is in stable condition after she was hit by a stray bullet while inside a West Los Angeles apartment complex, according to authorities.

The Los Angeles Police Department said the 8-year-old was inside her residence when a live round entered through a wall and struck her around 2:45 p.m. Sunday on the 4700 block of Slauson Avenue in Del Rey.

She was transported to a local hospital in stable condition after she was hit in the head by the bullet, family members said. 

Her family says that she was sitting on the couch in their living room as they enjoyed an afternoon at home when they heard the gunfire. Marisela Jacinto Ambrosio said that she looked up and saw her daughter's head bleeding. She yelled for her husband, and within minutes, they were rushing her to the hospital. The girl, who hasn't been publicly identified, has since returned home after she was treated at the hospital.

The Ambrosio family says that they're hopeful for justice for what happened to their little girl, who is now terrified to live in their apartment. 

Police say that the bullet came from a neighboring apartment.

Though no one has yet been taken into custody, an investigation into the matter is already underway. They believe the girl was struck by a bullet from a 22mm gun, which they recovered in the apartment next door. Police also found a shell casing inside of the Ambrosio family's unit, and believe that the weapon was being cleaned when it misfired. 

"When we are able to make an arrest, we will make an arrest," said LAPD Captain Eric Eppolito. "We take it very seriously when anyone is shot, especially an 8-year-old. So, it is at the top of my list."

Investigators have interviewed several people of interest in the shooting, they told CBS Los Angeles. On Tuesday, officers confirmed that one person was taken into custody for negligent discharge of a firearm. They have not yet identified the person who was arrested.
