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.
Deputy Sheriff I Demos gave the Milwaukee County Sheriff's Office 15 years.
Thank you for your service to the Milwaukee community, and for your service before it. Gone but never to be forgotten.
Rest easy, brother.
