June 1 (UPI) -- At least six people were killed Monday in a series of shootings in an Iowa city that authorities said stemmed from a domestic dispute.

The suspect was identified as Ryan Willis McFarland, 52, of Muscatine, located along the eastern Iowa border with Illinois, and also died from a self-inflicted gunshot wound that was fired after being confronted by police on the Riverfront Trail near a pedestrian bridge.

Authorities said he shot six people, all believed to be family members.

"Today, I simply do not have the words [for] this act of evil and what it has done to our community," Muscatine Police Chief Anthony Kies told reporters at a press briefing.
