In a press release, police said that officers responded to multiple 911 calls placed at around 8 p.m. on Sunday night reporting a fight in a suburban Middleborough neighborhood. They arrived to find Pomerleau suffering from “multiple stab wounds” and immediately transported him to a nearby hospital where he was pronounced dead.

According to police, Horsman and Pomerleau were having an argument in the moments leading up to the alleged stabbing. Police said there were several witnesses to the argument, and family members told local ABC affiliate WCBV that there had been a longtime feud between Horsman and his mother’s boyfriend that reached a head over the weekend.

Local CBS affiliate spoke to Jeff Burr, a neighbor who said he knew Pomerleau for “30 years” and told the outlet, “I’ll tell you, he was like a gentle giant. He was a great guy. He’d give you the shirt off his back. You know, he really would.”

Pomerleau’s family said in a statement obtained by WCVB, “My dad was a deeply loving father. He had a way of making everyone feel like family and was endlessly dedicated to his kids and grandchildren.”

Details about the nature of the argument between Horsman and Pomerleau were not made public.

Police said that Horsman was identified by witnesses at the scene and taken into custody without incident. He was scheduled to be arraigned on Monday at Wareham District Court after being charged with murder by the Plymouth County District Attorney’s Office.
