OROFINO, Idaho -

The Orofino Police Department in Clearwater County have identified the five people killed in Saturday's house fire and believe all five died in their sleep.

The victims include a family of four and a friend who was staying over at the house for a birthday celebration. They are: Allen West, 31, Rosemary Wooster, 39, Trevor Wiley, 17, Zachary Wooster, 13 and Colby Stedman, 13.

Investigators say based on the position of the bodies and other factors it is believed that all five victims died in their sleep as a result of smoke inhalation. It is not believed that any of the victims attempted to flee from the fire.

An official cause of death will be determined in autopsies that have not been scheduled as of Sunday morning. They are expected to take place during the upcoming week.

A neighbor reported the fire at 1:38 a.m. Saturday. The home, located at 261 Cedar Street, was engulfed in flames when the fist fire crews arrived on scene at 1:43 a.m.

The cause of the fire was determined to be an overloaded power cord on the front porch that was plugged into an electric grill, according to the Orofino Fire Chief. The chief also said that there were no working smoke detectors in the home, but the fire damage was so extensive that he could not be certain that they did not exist.
