On Saturday four people died in an Aurora, Colorado shoot out.
Police were called to the home where the shoot out happened early in the morning. After hours of failed negotiations, they shot the gunman and entered the home.
Family members say he was 33-year-old Sonny Archuleta. A police background check shows he had been arrested at least three times before on weapons charges. Family members also say they think he had a drug problem.
The victims include Archuleta's sister-in-law, 29-year-old Stacie Philbrook, and her step father, 56-year-old Anthony Ticali. The third victim has not been identified.
The shoot out is still under investigation.
