Jonathan Randall Koleski.
Deputy Sheriff Jonathan Koleski and Deputy Sheriff Marshall Ervin were shot and killed while serving a felony theft warrant at 2474 Hampton Glen Court in Marietta shortly before 8:00 pm.
They were taking the subject into custody when another subject inside the home confronted them with a firearm. Both deputies gave commands for the man to drop the firearm before an exchange of shots. Both deputies suffered fatal wounds. The wanted subject and the shooter both barricaded themselves in the home but were both taken into custody later in the night.
The man who shot Deputy Ervin and Deputy Koleski plead guilty to murder in December 2022 and was sentenced to two life terms in prison.
Deputy Sheriff Koleski was a United States Army and Georgia National Guard veteran and had served with the Cobb County Sheriff's Office.

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 Koleski gave the Cobb County Sheriff's Office 15 years.
Thank you for your service to the Marietta community. Thank you for your service before it. Gone but never to be forgotten.
Rest easy, brother.
— S. Vincent Anthony, U.S. Army 1985-1993
