Maine Gov. Janet Mills formally appointed Patrick Polky on Thursday, July 28, as the new sheriff in Knox County.

Polky, who had been the chief deputy under Tim Carroll, will serve the remainder of Carroll’s term that runs through the end of the year.

Polky is also uncontested on the Nov. 8 ballot for a full four-year term as sheriff.

Carroll stepped down as sheriff to take the job of Rockland Police Chief. State law requires the political party of the former sheriff to make a recommendation to the governor who then makes the appointment.

Polky started his law enforcement career in 1999 as a parking officer in Camden. He worked for the town for several years as a patrol officer and patrol sergeant.

In 2013, he left to pursue further education.

He returned to law enforcement in 2014 with the Knox County Sheriff’s Office as a patrol deputy on North Haven. In 2015, he was promoted to patrol supervisor sergeant. In 2017, he was promoted to patrol administrator lieutenant and in November 2018 was named by Carroll as the chief deputy.

In 2016, Sheriff Donna Dennison honored Polky for life-saving measures in preventing a despondent man from committing suicide.

Polky retired from military service after 21 years in 2016. He enlisted in 1995, leaving the active service in 1998. He entered the Maine Army National Guard as a sergeant and was assigned as a technical engineer. He was reassigned to positions such as squad leader, detachment non-commissioned officer and platoon sergeant.

He was deployed to Afghanistan in 2006 and 2010. He received the Bronze Star medal, Meritorious Service medal, Joint Services Achievement medal, and Distinguished Order of Saint Martin.
