MILLIS, Massachusetts — A surprise family birthday party turned into a bloodfest when a deranged man ran in and attacked his parents with a knife, just after allegedly killing his girlfriend in the apartment they shared, police said.
Family members were preparing a round of toasts in a banquet room at the Primavera restaurant Saturday night, when 24-year-old Benjamin Walsh charged in and stabbed his mother in the stomach and slashed his father.
Relatives then tackled Walsh and tied him up until police arrived, the Boston Herald reported. Investigators later went to Walsh’s apartment in nearby Needham, where they discovered the body of his 20-year-old girlfriend, Olivia Bergstrom, with numerous stab wounds.
Benjamin Walsh has struggled with mental health and substance abuse issues, his father told WFXT-TV, and was “out of his mind” when he attacked.
“It just seems like he came here on one mission,” the injured father said. “I think when Ben realizes what he did, he will be devastated.”
Benjamin Walsh was hospitalized after being taken into custody, prosecutors said.
