Rapper J $tash allegedly killed his girlfriend as her three children watched before turning the gun on himself, People reports.

The rapper, whose real name is Justin Joseph, allegedly shot and killed his girlfriend Jeanette Gallegos, 27, in Temple City, California. According to the New York Post, the couple got into an argument before Joseph led Gallegos into her bedroom, where police found their bodies.

Police responded to a domestic violence call at the home the morning of New Year's Day.

"The female victim sustained multiple gunshot wounds, while the male victim sustained an apparent self-inflicted gunshot wound," police officials said, People reports.

"Right now, the evidence at the scene and the preliminary information we have from the children in the home is that it's a murder-suicide," Lt. Derrick Alfred told KTLA.

The victim's three children, ages 5 to 11, were not harmed during the shooting, the Associated Press reports. In its official release, the sheriff's department detailed that all three were taken away from the home and placed with relatives.

One of the children called their grandmother, who advised the child to call 911, according to the Post.

Gallegos was dating the California rapper for about a year, and he has no relation to any of the children. The investigation is ongoing.
