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.
Deputy Sheriff Nelson gave the Pima County Sheriff's Department 1 year.
Thank you for your service to the Tucson community, and for your service before it. Gone but never to be forgotten.
Rest easy, brother.
— S. Vincent Anthony, U.S. Army 1985-1993
