DOVER, N.H. — A man facing three murder charges in late June’s knife slayings in northern Maine says he’s “vicious” when he’s drinking.

The New Hampshire Union Leader says Donald Hiltz ran into the suspect, 20-year-old Thayne Ormsby, while Ormsby was staying with a friend at an apartment in Dover after the killings in Amity, Maine.

Hiltz, who lives in the Dover apartment complex, says he struck up a conversation with Ormsby in the parking lot. During the conversation, Hiltz said Ormsby started “talking about how he was an alcoholic and he gets very vicious when he drinks.”

Ormsby was arrested Friday at the Dover police station and is to be arraigned Tuesday in Dover District Court. He’s charged in the deaths of 55-year-old Jeffrey Ryan, Ryan’s 10-year-old son Jesse, and 30-year-old Jason Dehahn.
