Authorities in Iowa are investigating the fatal shootings of six people who they believe were killed by a relative who took his own life when confronted by police Monday.

Police were called Monday to a home in Muscatine, about 50 miles southeast of Cedar Rapids, where they found four people fatally shot, Muscatine Police Chief Anthony Kies said during a news conference.

Officers later found the suspect, 52-year-old Ryan Willis McFarland, of Muscatine, on a trail in the city, Kies said.

“While talking to Ryan Willis McFarland, he took his own life,” he said.
