A MAN SUSPECTED of fatally shooting two men and seriously wounding two others had to turn himself in twice before Detroit police would arrest him, authorities said.

Detroit police said the 36-year-old man got into an argument at a party yesterday, retrieved a gun and opened fire. Four people were shot, and two died.

The man turned himself in at a fire station about two hours later, and fire officials called police, but no officers turned up.

Police said in a statement that “due to area patrol units being busy handling high priority runs, no units were dispatched to the location.”

The man eventually went to a police station, where he was arrested.

Police Chief Ralph Godbee said he has ordered an investigation into why no patrol car was sent to the fire station. Police should have made “every effort to ensure that this person was taken into custody,” he said in a statement last night.

Police spokeswoman Sgt Eren Stephens said the department would examine what police units were doing at the time the suspect tried to surrender, including whether they might have been involved in other aspects of the shooting investigation.

Police did not immediately release the name of the suspect or the victims or provide details on the shooting investigation. They said the men who were shot ranged in age from 19 to 37.
