Authorities in Iowa are investigating the fatal shootings of six people. They believe a relative, Ryan Willis McFarland, killed them before taking his own life when confronted by police Monday. Police were called to a home in Muscatine, where they found four people fatally shot. Officers later found McFarland on a trail in the city. Two other men also believed to be McFarland’s relatives were found fatally shot elsewhere in the city. Authorities have not released the victims’ names. The police department continues to investigate and has asked anyone with information to contact them.
