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.

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.”
