Five people were found shot to death in a murder-suicide inside an Arizona home Tuesday night were all members of the same family, police say.

Police said 25-year-old Christopher Carrillo killed his family before turning the gun on himself.

The others killed were 58-year-old Raul Carillo, 53-year-old Karen Saari, 32-year-old Erik Carrillo and 17-year-old Isela Rodriguez.

The bodies were found Tuesday evening by a man who went to the single-story house, police say.

Sgt. Pete Dugan told The Associated Press that officers found the bodies in the home at about 6 p.m. local time.

Dugan told the AP that all of the victims had "obvious signs of gunshot trauma."

The shootings occurred in a blue-collar neighborhood on the south side of Tucson that residents said has seen an uptick in drug dealing recently.

The home had a no-trespassing sign on the door, and two tricycles and a small basketball court out front. An abandoned home stood on one side of the residence.

Neighbor Araceli Zatarain said a family of four has lived in the home for more than 20 years. She said police officers arrived at the home with guns drawn and demanded that one of the family's sons come out. Police later went inside, where they found the bodies.
