Police believe new video shows man who killed WSU Sgt. Collin Rose

DDOT bus video shows man running minutes after fatal shooting

DETROIT – Local 4 has obtained new surveillance video that police believe shows the man who fatally shot Wayne State University Officer Collin Rose Nov. 22 in Detroit.

The video, taken by a camera on a Detroit Department of Transportation bus about 10 minutes after the shooting, shows a man running, walking and running again in front of the bus.

"The new video shows the same person which we tracked running from the scene crossing Grand River in the area of Grand River and Rose Parks after the shooting," Michigan State Police homicide task force Sgt. Phillip Duplessis said.

You can see the video below:

"Look at the posture," DPD Officer Lance Sullivan said. "Look at the way they are walking and look at the clothing that the person is wearing and see if you know who it is."

Sullivan and Duplessis are part of the task force trying to find Rose's killer.

"Right now we're investigating every possible lead," Duplessis said.

Rose was shot in the head while he patrolled the streets of Detroit just off Wayne State's campus at Lincoln and Seldon streets.

The killer left behind a blue and yellow mountain bike, a flashlight and gloves. Evidence has been recovered from the items, but to whom they belong is still a mystery.

"We're worried that this isn't going to be the only time that this person commits one of those kinds of atrocities," Randy Rose, Collin Rose's father, said.

Rose's parents live 140 miles away in the small town of Richland. A tree in the city park is decorated with blue ribbons in Rose's honor.

Karen and Randy Rose spend a lot of time with one of their son's dogs. They haven't talked to the media about their son's death until now.

"We're stepping out a little bit of our comfort zone to make a plea that says, 'Hey, if anyone knows anything, please share the information with the police,'" Randy Rose said.

Anyone who knows something about the bike or the person who was riding it in the days before Rose was killed could help police in the investigation, the Roses said.

"It's tough to move on," Randy Rose said. "We still have kind of an open wound."

The Rose family said the outpouring of support from officers and K9 units at the funeral service was unbelievable.

"We just didn't realize how many people he touched," Karen Rose said. "He loved what he was doing. He loved it. He loved his job and he died doing what he loved."

"He loved Detroit, he really did," Randy Rose said.

The couple said it's their job to keep pushing for answers, begging for someone to come forward for justice.

"We all grew up in neighborhoods," Randy Rose said. "You kind of know who belongs in your neighborhood and who doesn't."

But to find a killer on the loose, someone who might know the person could unlock the key to the mystery.

"No matter how insignificant they might think that that tidbit of information would be, we beg them, we're pleading to them to please call the task force," Karen Rose said.

"We want the community to be safer," Duplessis said. "We want more people to feel like they can go outside and walk, drive, ride, play and not have to worry about a police killer out on the street."

Crime Stoppers is offering a reward of $105,000 for information leading to the arrest of Rose's killer.

Case background: 

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.
