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.

Corporal Koscelnick gave the Pennsylvania State Police 7 years.

Thank you for your service to the people of Pennsylvania, and for your service before it. Gone but never to be forgotten.

Rest easy, brother.

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