GRAND RAPIDS, Mich. -- A fast-spreading fire gutted a home, killing seven family members ranging in age from 3 to 74, officials said Thursday. The 1 1/2-story, wood-frame home was engulfed in flames, and there were no signs of life when firefighters arrived about 11:20 p.m. Wednesday, fire battalion chief Gerard Salatka said. The bodies were found on both floors. Officials do not believe anyone escaped, he said. The cause of the blaze was not immediately determined. It was unclear whether the home had working smoke detectors. Firefighters did not hear any.
