Prosecutor drops charges in death of Detroit college officer

Prosecutors dropped murder charges Wednesday against a man in the killing of a Detroit college police officer who was shot in the head while on duty.

Wayne County Prosecutor Kym Worthy said charges against DeAngelo Davis, 31, of Detroit, were dropped. Davis was accused of shooting Wayne State University Officer Collin Rose on Nov. 22. Davis had been jailed without bond since his arrest that night. He faced charges of first-degree murder and murder of a police officer.

Davis became a suspect in Rose's shooting almost immediately. In a statement after he was charged, Worthy said Davis was riding a bicycle when Rose stopped him. Rose was shot shortly after requesting help from other officers.

Detroit Police Chief James Craig said at the time that Rose was investigating possible thefts of navigation systems from vehicles.

Wayne State, which has more than 27,000 students, employs about 65 officers. Rose, 29, died a day after the shooting and was posthumously promoted to sergeant. He is the only Wayne State officer killed in the line of duty.
