Authorities have found eight people dead in a Michigan home after a fire, with some victims having gunshot wounds. Police and fire officials responded to the blaze in Grand Haven Township on Friday. They discovered the bodies of two adults and six children. Investigators have not fully identified the victims or determined the official cause of death for them. The Ottawa County Sheriff's Office said they are not looking for outside suspects and that one theory is a murder-suicide. Arson investigators are assisting with the investigation.
