COMPTON (CBSLA) — A Hispanic man has been arrested on murder charges in a shooting that killed his longtime girlfriend and critically wounded the couple’s 8-year-old daughter early Saturday morning at their Compton home.

Juan Rodriguez, 29, was arrested on charges of murder and assault with a deadly weapon.

The shooting was reported at 1:42 a.m. Saturday at a home in the 12400 block of South Grandee Avenue.

The Los Angeles County Sheriff’s Department reports that Rodriguez and his girlfriend Myra were engaged in a verbal argument when he produced a gun and fired several shots at her, striking her in the chest.

The couple’s three children, an 8-year-old girl, 3-year-old girl and 1-year-old boy, were home at the time. The 8-year-old girl was accidentally struck by the gunfire, the sheriff’s department said.

Deputies responded to the home to find the mother dead at the scene. They also located two of her children, the 1-year-old boy and 3-year-old girl, unhurt.

However, shortly after, deputies learned the father had rushed their third child, the 8-year-old girl, to a nearby hospital with gunshot wounds. At last report she was in critical condition, LASD said.

A source told CBSLA’s Greg Mills that the girl was first taken to Martin Luther King Jr. Community Hospital and then brought to Harbor-UCLA Medical Center which is the closest trauma center.

Rodriguez was arrested after being interviewed by homicide detectives. The couple had been together for about nine years, the sheriff’s department said.

Rodriguez is being held without bail. Anyone with information on the shooting should call LASD at 323-890-5500.
