Wayne State University Police say Officer Collin Rose has died after being shot on Tuesday night.

Wayne State University President M. Roy Wilson released this statement:

I am saddened to report that a short time ago, Wayne State University officer Collin Rose died from the gunshot wound he suffered while working in the line of duty yesterday evening. This is a tragedy felt by all of us -- Collin and his family and friends, his fiancée, and our campus and community. Please keep Collin and his fiancée and family in your thoughts and prayers. Collin served Wayne State with distinction, and we owe those he left behind our deepest sympathies and our strong support. Please keep all our police officers in your thoughts as well. Collin is the first and only Wayne State officer ever to fall in the line of duty. Our officers mourn with us, but these dedicated, professional men and women continue to serve us courageously, every day. We can honor Collin’s memory best with our ongoing gratitude and support for all of our officers.

Rose, 29, was on life support at Detroit Receiving Hospital after he was shot in the head after stopping someone on a bicycle near Lincoln and Brainard around 6:30 p.m. Tuesday. He died just after 5 p.m. Wednesday.

Rose's family has issued the following statement:

"The family members of Collin Rose want to thank everyone for their outpouring of support. Collin loves working at Wayne State and has enjoyed the challenges of being a canine handler. We're thankful his two canine partners were not harmed and appreciate the regional law enforcement response to the crime scene. We are optimistic about his recovery and ask for your prayers during this time."

Rose was a canine officer who named his partner "Wolverine" in memory of fallen DPD Officer Patrick Hill. "Wolverine" was Hill's code name. He died in October 2013 after being shot in the line of duty by a murder suspect in April of that year.

Rose was with the Wayne State University Police Department for five years.

"This is a tragedy of immense proportions," said Dr. M. Roy Wilson, president of Wayne State University.

Officials say a Wayne State University police officer has not been shot in 36 years.

Original story on Hill's death.

Rose was on duty, but off campus at the time of the shooting.

Rose reportedly stopped someone on a bicycle right before the incident. Police released a picture of a unique bicycle that the suspect was riding at the time of the shooting. Officers say that picture led them to Davis because he was identified as having been seen riding the bike.

Davis was taken into custody at Michigan and Selden and driven to the Detroit Detention Center for questioning.

According to officials, it's is not clear exactly why Rose made the stop.

Chief James Craig says Wayne State University police made several arrests in the area where the shooting occurred last night. Those arrests were related to a recent rash of car break-ins, where items were stolen.

Police say Rose was investigating those break-ins, but it's not clear why he stopped the bicyclist.

Rose was discovered by another police officer who responded to the scene.

The ATF is offering a $5,000 reward for information leading to the recovery of the gun used in the shooting, which is still missing. Anyone with information can call 888-ATF-TIPS.
