MONMOUTH — After serving the town for over a decade, police Chief Kevin Mulherin has resigned.

In his letter of resignation, he thanked the town for the opportunity to serve. Mulherin’s last day was Nov. 12.

“Over the past 10 plus years I have enjoyed the many challenges of my position with the Town of Monmouth along with the positive interactions with the citizens of Monmouth,” wrote Mulherin.

Town Manager Linda Cohen said the former chief has already moved onto a new job. She said the job was not in law enforcement, and that she did not specifically know where he went.

Mulherin could not be reached for comment this past week.

“We’re sorry to see him go, but happy to see him move on to his next phase,” she said. “He was a good guy; it will be a loss to us.”

Before serving as Monmouth’s police chief, Mulherin worked as a lieutenant with the Auburn Police Department, where he served for 24 years. He also worked as a patrolman, criminal investigator and briefly as an agent with the Maine Drug Enforcement Agency.

Peter Struck, deputy chief of the Winthrop Police Department, will serve as Monmouth’s interim police chief until a replacement can be found.

Struck did not immediately respond to a request for comment.
