What's missing in this report?

Los Angeles police say a 9-year-old boy playing with a loaded gun accidentally shot and killed his 2-year-old brother.

Police said in a statement Saturday that officers and paramedics found the toddler with a bullet wound to the torso after they were called to the boys' home in the San Fernando Valley.

Police say the 2-year-old died at a hospital Friday night.

The statement says homicide detectives interviewed family members and determined that the gun had gone off while the 9-year-old was playing with it.

Police say no criminal charges are pending.

The parents are missing. Who owned this gun? How did it get in the hands of the boy? It just appeared and was fired at the baby? There is a crime in this incident, but it's prevented from reaching the surface of the story.
