In tribute

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 Sack gave the Peoria County Sheriff's Office 20 years.

Thank you for your service to the Peoria community, and for your service before it. Gone but never to be forgotten.

Rest easy, brother.

— S. Vincent Anthony, U.S. Army 1985-1993
