Tributes
I served 1985 to 1993. You served too, before the badge - different uniform, same idea. You go where you are sent and you do not get to pick the call.
Police Officer Mach gave the Detroit Police Department 2 years.
Thank you for your service to the Detroit community, and for your service before it. Gone but never to be forgotten.
Rest easy, brother.
