DETROIT (AP) - Authorities have confirmed the identity of the 2-year-old boy who died in a house fire in Detroit. Wayne County Medical Examiner spokeswoman Lisa Croff said Monday the cause and manner of Kamari Livingston's death haven't been determined. He was the only person not to survive the fire early Friday near the city's border with Hamtramck. Fire officials said last week four other children were rescued from the home and two adults were taken to the hospital with burns and smoke inhalation. Two Hamtramck firefighters burned while they and Detroit firefighters were rescuing children were treated at a hospital and released. The cause of the fire also remains under investigation, but firefighters say it might have been due to an electrical problem.
