Fullerton, Calif., police found two men and a woman dead inside a home after a young girl called police dispatchers Saturday morning and said her parents had died, authorities said.
The cause of the three adults' deaths is under investigation but the case is being treated as a multiple homicide, said Fullerton police Sgt. Jon Radus.
Two children, including the girl who called police, were found unharmed at the home, he said.
The names, ages and relationship among the three adults who were found dead are under investigation, Radus said.
Police received the child's call at 8:21 a.m. and the first officers arrived at the home at 8:26 a.m.
"This is obviously a tragic event," Radus said in a statement. "The Fullerton Police Department has committed all its resources to identify who is responsible for committing this act."
