GARDNER — A Groton man charged with animal cruelty for allegedly killing an Ashburnham goat is still being held at the Worcester County House of Correction after failing to post a $500 cash bail, according to court officials.

Dominick Tidd, 18, who is homeless, was ordered to undergo a mental-health evaluation during his arraignment in Winchendon District Court on Monday.

In an investigative report of the incident, a former classmate of Tidd’s told police that the 18-year-old was living in the woods around West Groton, and has mental-health and substance-abuse issues.

The classmate told police he saw Tidd on Friday after the teenager allegedly removed one of three goats from a pen he cut open in the backyard of an Ashburnham homeowner and killed the animal.

Tidd told the classmate how and why he had done it, according to court documents.

The Nigerian dwarf goat was reported missing and found dead Thursday with stab wounds and its throat slashed. A rectangular hole was cut into its pen.

Pat Stewart, who raises Nigerian dwarf goats at Hames & Axle Farm on Kraetzer Road in Ashburnham, said she sold the three-month-old female goat to a family.

The family’s child named the animal “Marshmallow” because of its white coloring, she said.

Steward said the two male goats the family also purchased from the farm may also be impacted by the animal’s death.

“They’re mourning the loss of that little goat,” she said. “They form friendships.”

Tidd is also facing charges related to stealing the goat and destruction of property for cutting a hole in the pen.

His next court appearance is scheduled for July 13.
