DETROIT (AP/WOOD) — 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 and he is no longer a suspect at this time. Davis was accused of shooting Wayne State University officer and West Michigan native 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.

NBC-affiliate WDIV-TV, citing sources close to the investigation, reports Davis was shown on video in a business at the time of the shooting.

“As you can imagine the officers from the task force including the Michigan State Police and the Detroit Police Department have been working diligently and literally, literally, around the clock along with members of my office on this case,” said Worthy. “We all remain deeply committed to making sure justice is done in this case, to make sure the perpetrator for the killing of Officer Rose is brought to justice. We will continue to work hard on this case.”

The prosecutor would not take questions following the press conference. Officials also announced that the reward in the case has been increased to $15,000.

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.

Rose was a graduate of Gull Lake High School and started his career in law enforcement in the village of Richland in Kalamazoo County. Funeral services were held last week.
