DETROIT (AP) — Michigan Gov. Rick Snyder and state Attorney General Bill Schuette are offering condolences to fellow officers and the family of slain Wayne State University police Officer Collin Rose.

The 29-year-old Rose died Wednesday evening in a Detroit hospital from a gunshot wound to the head.

He was shot Tuesday night in Detroit’s Woodbridge Estates neighborhood while conducting a theft investigation. Rose radioed to say he was investigating possible thefts of navigation systems from vehicles and that he was about to speak to someone on a bike. Officers who arrived on the scene found Rose injured on the ground.

Schuette said in a statement that Rose “was doing his job, serving his community and protecting all of us, when he was tragically gunned down.”

Snyder says Michigan residents are “collectively mourning his loss.”

A Detroit man was arrested Tuesday night as a suspect in the shooting, but no charges have been filed.

Rose was a five-year veteran of the university’s police force, is the only Wayne State officer killed in the line of duty.
