At least six people are dead and two are in critical condition after a gunman went on a seven hour shooting spree across three Michigan locations early Sunday morning.

The suspect, 45-year-old Jason Dalton, was arrested early Sunday morning after a shooting spree in the parking lots of a Michigan apartment complex, a restaurant, and a car dealership. Authorities believe the shooting began Saturday evening and the suspect shot the victims at random.

AP reports:

Kalamazoo County Undersheriff Paul Matyas described a terrifying rampage that began about 6 p.m. outside the Meadows Apartment complex in Richland Township, on the eastern edge of Kalamazoo County, where a woman was shot multiple times and seriously wounded. She was scheduled for surgery Sunday morning.

A few hours after the woman was shot, a father and son were killed while looking at cars in a car dealership. Fifteen minutes after, five people, including a teenage girl, were shot in a parking lot of a Cracker Barrel restaurant.

Dalton did not resist arrest, according to sources. ““This is every community’s nightmare — when you have someone going around just randomly killing people, no rhyme, no reason. Obviously, we’re going to interview the individual and we’re hoping to gather … what he was thinking, what type of methodology he used, if any, in these killings,” said Matyas.

This is a developing story.
