OROFINO, Idaho (AP) — Authorities in northern Idaho have released the names of five people they believe died in a house fire Saturday morning in Orofino pending positive identifications through autopsies.

The Orofino Police Department yesterday identified the victims as 39-year-old Rosemary Wooster, 31-year-old Allen West, 17-year-old Trevor Wiley, 13-year-old Zachary Wooster, and 13-year-old Colby Stedman. Four of the victims lived at the home, while Stedman was staying overnight as a friend of Zachary Wooster.

The boys shared a birthday several days earlier. Investigators say all five likely died in their sleep from smoke inhalation, and none attempted to flee the fire and the bodies were badly burned. Fire investigators say an overloaded extension cord on the porch likely caused the fire, and that no smoke alarms were found in the home.
