Police arrested two individuals allegedly involved in separate domestic violence incidents over the weekend.

At 3:46 p.m. on May 26 Belfast police officers responded to call about an argument between Gage J. Gagnon, 19, of Belfast and his girlfriend. After arriving at the residence, officers observed red marks on the victim’s neck, Belfast Police Chief Mike McFadden said, that appeared to indicate she was assaulted.

After conducting interviews and gathering additional evidence, McFadden said officers determined Gagnon allegedly choked his girlfriend to the point that blood vessels in her eyes burst.

Gagnon was arrested and charged with aggravated assault and taken to Waldo County Correctional Center, the chief said.

Officers responded to another domestic incident early in the morning of May 27. At 2:15 a.m., police were contacted by a male victim who said his girlfriend was assaulting him. Responding officers determined that Shelly A. Trisch, 39, of Belfast allegedly struck the victim, who was able to capture the assault on his cellphone while it was happening, McFadden said. McFadden said he did not believe the victim suffered any serious injuries.

Trisch, who has prior domestic violence convictions, was arrested and charged with domestic violence assault, the chief said.
