Four other family members, including two children, were staying at their homes as guests, police said. When the victims were found, one of those guests rushed outside to seek help, found someone who was passing by and l ''. called at 911.
Police have identified apparent gunshot wounds to each of the victims, but autopsies will be conducted to determine the cause of each of their deaths, the statement said. A police spokesman said that there appeared to be no threat to other members of the community.
"This tragedy will have an impact on family, friends, co-workers and all those who know this family," said Sgt. Dan Wade with the West Des Moines Police Department. "We are continuing our work during this investigation and will continue until we have answered as many questions as the evidence allows."
