Middleboro stabbing suspect indicted for murder by Plymouth County grand jury

MIDDLEBORO — A Plymouth County grand jury indicted Andrew Horsman, 41, on one count of murder in connection with the fatal stabbing of 66-year-old Paul Pomerleau in Middleboro.

Plymouth County District Attorney Timothy J. Cruz announced Horseman’s indictment for the murder charge Friday, Sept. 26. According to the district attorney’s office, Horseman is being held without bail, and will return to the Brockton Superior Court to be arraigned “at a later date.”

The grand jury brought the charge against Horseman after prosecutors gave evidence of the June 28 fatal stabbing that occurred at the Fairview Street residence where the two men lived in Middleboro.

Horseman stabbed Pomerleau over 17 times, and poured lighter fluid on the victim’s body in an attempt to “light him on fire,” according to written statements from responding officers. According to court documents, Middleboro Police Detectives interviewed several on-scene witnesses who reported an argument over a steak and sausage dinner led to the fatal stabbing.

After witness interviews, police determined Horsman as the suspect and he was taken into custody near the scene of the stabbing. He was located near the former Middleboro Department of Public Works building on Wareham Street, where Police said he called 911 shortly before his arrest and told a dispatcher he wanted to “turn himself in.”

Pomerleau had been in a relationship with Horsman’s mother for more than 20 years. According to family members, the two men had ongoing tensions, which primarily revolved around Horsman’s lack of employment and residence at the house. 

Pomerleau was transported to Morton Hospital in Taunton, where he was pronounced dead of his injuries, June 28.
