ST. CLAIR SHORES - The St. Clair Shores police officer was trying to pull over a different vehicle when he slammed into the bike on Eight Mile Road between I-94 and Beaconsfield.
The police cruiser was not chasing the third, uninvolved vehicle when the crash occured at the St. Clair Shores and Harper Woods border.
"I just heard the noise and when I came out I saw the guy on the ground," said neighbor Shawn Holcomb. "The police officer was right there. I was thinking they were here fast - then I found out it was the cops that actually hit him."
Bush, from St. Clair Shores, died about 45 minutes later at the hospital.
"I brought a rose from my daughter's wedding and placed it over there."
Michigan State Police tell FOX 2 that it could take a couple days before a formal report will be issued.
