He Attacked His Parents With A Knife. But It Wasn't Until Cops Visited His Home That They Found His Most Disturbing Crime.

He stabbed his 20-year-old girlfriend to death and then went to a bar yelling he was going to “kill everyone” and attacked his parents.

Now, he won’t hurt anyone for decades.

Recently, a judge in Massachusetts sentenced Benjamin E. Walsh to life in prison for the killing of 20-year-old Olivia Bergstrom in 2018. He will eligible for parole after 25 years, according to WHDH.

Walsh pleaded guilty to second-degree murder after he was initially charged with first-degree murder, according to WHDH. The plea agreement was supported by Bergstrom’s parents, prosecutors said.

“This brings its own finality to the proceeding,” Norfolk County District Attorney Michael Morrissey said, and WHDH reported. “The outcome of a trial is never assured, and appeals procedures in murder cases span many years. I cannot imagine the pain of Olivia’s parents, and my thoughts are very much with them today.”

Shortly before Valentine’s Day in 2018, Walsh stabbed his girlfriend, Bergstrom, in their Needham, Massachusetts, apartment. He then went to a restaurant and stabbed his parents during a family birthday party.

Police found a blood scene at the restaurant when they arrived, according to CBS Boston. Witnesses said that Walsh walked in and yelled profanities. He then lunged at his mom, stabbing her, and then stabbed his father in the abdomen.

Walsh was yelling, “I want to kill you! I’m going to kill everyone!” investigators said and CBS Boston reported.

Five men restrained Walsh until police arrived, according to the report. He then yelled at the officers and threatened to kill them as well.

Walsh had wrapped the knife in a tablecloth and gave it to police. Investigators suspected Walsh was under the influence and that he had a history of mental illness.

Officers were initially called to the restaurant and when someone expressed concern for Bergstrom, police went to the apartment to findd her dead, CBS Boston reported.

Shortly after the murder, Oliva’s grandfather, Paul Bergstrom, released a statement, CBS Boston noted.

“Devastated does not even begin to describe how we feel about losing our Olivia. Olivia was a smart, vibrant, beautiful young woman with a bright future ahead of her. She was a beloved daughter, sister, granddaughter, niece, and friend. Olivia was a lover of animals who never met a horse she couldn’t win over. She was passionate about living a healthy life,” it read.” She had a dog named Scarlett. She loved her family fiercely. Our hearts are broken at the thought of Olivia not being in our lives, taken from us and her future in a way we cannot comprehend. We know her spirit remains with us and we will do everything in our power to keep her memory alive and celebrate the short time we had the privilege of having her in our lives.”
