DETROIT – Thursday will mark a somber anniversary for the family and friends of Wayne State University Police Sgt. Collin Rose.
It's the one-year anniversary of the night Rose was gunned down. Loved ones gathered Wednesday evening for a vigil to honor the fallen officer.
They started with a traditional radio call, followed by a moment of silence and funny and heartwarming stories about Rose.
Sgt. Rose murder case
Rose was shot in the head Nov. 22, 2016 while stopping a man on a bicycle in Detroit's Woodbridge neighborhood. Rose was investigating car break-ins in the neighborhood. He died nearly 24 hours later in a hospital surrounded by family.
The 29-year-old officer was engaged to be married in October 2017.
Police thought they had his killer. DeAngelo Davis, 31, was arrested Nov. 22 and charged with shooting and killing Rose. He was charged Nov. 25 with first-degree murder, a felony firearms violation, murder of a police officer and being a felon in possession of a firearm.
But the charges against Davis were dropped after surveillance video revealed that Davis was in a local business at the time of the shooting, sources close to the investigation said.

"All murder charges against DeAngelo Davis will be dismissed today," Wayne County Prosecutor Kym Worthy said. "He is no longer a suspect at this time. 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."
Detroit police released surveillance video of a person who they believe might have witnessed the deadly shooting. Watch here.

The Detroit Police Department confirmed that DNA found at the scene of Rose's shooting matches DNA tests of Durham, who is accused of shooting of two officers near Ash and Tillman.
Craig said police received "telephonic confirmation of a positive DNA match" between Durham and the suspect in Rose's murder.
"We are calling him a suspect in this matter, so that is a big first step," Craig said.
He said this DNA match is one component of the investigation and that police will continue to investigate, gathering evidence and conducting interviews.
Craig also said he plans to check up on the two officers who are still recovering in the hospital. He said they were in good spirits and were even laughing with him when he visited them.
"I think they will be happy," Craig said. "The one officer who had the more significant injuries, he said to me as I leaned over his bed, 'I believe that the suspect who shot us is the suspect who shot Collin Rose.'"
