Adris McCullough, Detroit man who surrendered twice to authorites, now facing first-degree murder charges

(CBS/AP) DETROIT - First-degree murder charges have been filed against an ex-con who had to turn himself in twice before Detroit police would arrest him in connection with a double slaying.

Authorities say 36-year-old Adris McCullough got into an argument at a party Saturday, retrieved a rifle and opened fire.

The say he shot four people, killing a 37-year-old and 23-year-old. McCullough tried to surrender at a fire station two hours later and fire officials called police, but no officers arrived. McCullough eventually went to a police station and was arrested.

Police Chief Ralph Godbee has ordered an investigation into what went wrong.

Wayne County prosecutor's spokeswoman Maria Miller says McCullough also is charged with assault with intent to murder and felony firearms counts. Miller says she doesn't think he has a lawyer.
