MINNEAPOLIS (AP) — A Minneapolis man accused of assaulting a 75-year-old man as he got off a Metro Transit bus is now charged with murder after the victim died.

Hennepin County prosecutors amended the charge against 23-year-old Leroy Davis-Miles to second-degree unintentional murder on Tuesday. Davis-Miles originally was charged with first-degree assault.

Minneapolis police said they were notified by the Hennepin County Medical Examiner’s Office that the victim died Tuesday afternoon.

According to the original complaint, the victim boarded a Metro Transit bus last Wednesday as did Davis-Miles and his companions. Bus surveillance video showed the victim asking the group to not be so loud.
