The DNA recovered from the shooting of two Detroit Police Department officers has been matched to the murder of Sgt. Collin Rose, said DPD chief James Craig during a press conference on March 17.
Raymond Durham, 60, was arrested on March 15 as a person of interest in the shooting of the DPD officers on Ash and Tillman Street.
Sgt. Rose was fatally shot on Lincoln and Brainard Street on Nov. 22, 2016. The gun, a .38 caliber revolver, was the same type of weapon used in both shootings.
DPD is currently conducting ballistic testing to see if the same kind of bullet was used.
Craig said the DNA confirmation was done by Michigan state police, and is just one component of the investigation. He said there are other facets in the investigation that he cannot talk about.
"Our work is not at all over," Craig said. "We will continue and we're certainly optimistic. We are calling him a suspect and that is a big first step."
He said the Wayne County Prosecutor's office will make an evaluation based on evidence presented by DPD as soon as possible.
"We anticipate charges forthcoming," he said.
On March 17, Wayne County Prosecutor Kym Worthy charged Durham in connection with the DPD shooting. He was charged with two counts of assault with intent to murder, two counts of resisting and obstructing the police causing serious impairment, one count of felon in possession of a firearm and five counts of felony firearm.
