ST. GEORGE, Maine — Gunner has done it again.

The tracking dog for the Knox County Sheriff’s Office helped Friday night in tracking down a man suspected of committing a domestic violence assault.

Joel Swain, 39, of St. George was arrested shortly after midnight and charged with domestic violence assault and disorderly conduct, according to paperwork filed in Knox County Unified Court.

Sheriff Donna Dennison said the department responded twice Friday night to a residence in St. George. The first time the alleged victim refused to cooperate and Swain was not there when officers arrived after receiving a call from the residence.

On the second call, the woman said she had been assaulted by Swain and cooperated with officers. Deputy Jeremy Joslyn, who is Gunner’s handler, responded along with Sgt. Matt Elwell.

Gunner was able to track Swain’s scent using a piece of clothing and found him hiding in bushes on the neighbor’s property, the sheriff said.

Swain was taken to the Knox County Jail and is being held without bail until he makes an initial appearance on the charges in court on Wednesday afternoon.

The woman did not require medical treatment, according to the sheriff.

Gunner has successfully tracked down other suspects in his service to the sheriff’s office.
