(DETROIT) — Detroit police are investigating why a murder suspect had to turn himself in twice before he was arrested.

The 36-year-old man walked into a fire station two hours after he allegedly shot four people at a party early Saturday morning, police said in a statement. Two of the victims died, while the other two were seriously wounded, police said.

The suspect, who was not identified, told firefighters at 3:20 a.m. Saturday that he was connected to the shootings, police said.

Fire fighters called the Detroit Police Department, but they were told all available officers were on high priority runs and that no one would be able to be dispatched to the station, ABC News affiliate WXYZ-TV in Detroit reported.
