Authorities have confirmed the identities of three burned bodies found inside an SUV in the desert south of Phoenix in a murder-suicide.

Tempe police said Friday that dental records showed they were 16-year-old Malissa Butwin, 14-year-old Daniel Butwin and 7-year-old Matthew Butwin.

Authorities say the records were needed because the bodies were burned beyond recognition.

The bodies of the childrens' parents — James and Yafit (yuh-FEET') Butwin — were identified Thursday.

Authorities say the woman and three children were killed by gunshot wounds, and the father died from a self-inflicted gunshot wound.

A U.S. Border Patrol agent found the five bodies in the burning SUV in a desert area Saturday in Pinal County, some 35 miles south of Phoenix.

The family was from Tempe, a suburb east of Phoenix.
