PHOENIX (Reuters) - A man shot to death four family members at a house in Phoenix early on Tuesday and died in a confrontation with police officers who entered the home, police said.
Police responded to a 911 call from someone at the property and arrived to hear gunshots and find part of the house on fire, said Phoenix police spokesman Trent Crump.
Firefighters battled the blaze while a police tactical team entered the house and shot the armed suspect, who may have shot himself as well during the confrontation, Crump said.
The suspect, the adult son of at least one of those killed, was pronounced dead at the scene, Crump said.
"We have no idea what the motive is, or what sparked this," he said.
Four of the suspect's family members were fatally shot, with two of them, including a girl, dying at the hospital, Crump said.
The names of the suspect and the victims were not immediately released.
