SPRINGFIELD, Mo. (AP) – Springfield police say a man who was wounded in a pay-by-the-week motel shooting that killed three others has died from his injuries.

The Springfield News-Leader reports 24-year-old Christopher Freeman of Springfield had been in critical condition since he and the three others were found shot in a room at the Economy Inn on Saturday. Forty-four-year-old Lewis Green, 43-year-old Trevor Fantroy and 29-year-old Danielle Keyes were pronounced dead at the scene.

Police suspect that the victims had been in the motel room for longer than a day and were shot with a handgun. It’s unclear how they knew each other.
