A not guilty plea was entered on Walsh's behalf and he is being held without bail.

Investigators say he stabbed his girlfriend, 20-year-old Olivia Bergstrom, in the apartment they shared in Needham then went to a restaurant in Millis and stabbed his parents during a family birthday party.

Jerry Gaita, the owner of Primavera, was driving away from the business when he received a call about the stabbings from an employee.

"I turned back into the parking lot ran in the front door to make sure the manager was on the phone calling the police. That's when I went into the room and saw the mom on the ground," he said.

According to court documents released Monday, police found a bloody scene at Primavera Saturday evening.

Witnesses say Walsh walked in, armed with a knife, yelled profanities and lunged at his mother, stabbing her in the stomach and then his father, also in the stomach.

The witnesses told investigators Walsh was yelling 'I want to kill you! I'm going to kill everyone!"

Court papers said five men restrained Walsh when police arrived. He allegedly yelled profanities at the officers and threatened to kill them as well.

Gaita said he wrapped the knife up in a table cloth and gave it to police.

Laura Walsh was in serious condition at Brigham and Women's Hospital in Boston Monday.

Walsh's father was treated and released.

Police said Walsh's mother Laura was on the floor bleeding with people pressing restaurant linens on her stomach. Then someone at the restaurant expressed concerns for Walsh's girlfriend, which led police to the couple's apartment.

Bergstrom was found with over a dozen stab wounds and pronounced dead.

"My family and I are so lucky to have so much love an(d) support thru all of this," Bergstrom's father, David Stoffregen, wrote on Facebook Monday. "Please everyone hug everyone you love today and then give them an extra one from all of us."

Paul Bergstrom, Oliva's grandfather, also released a statement on behalf of the entire family

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. 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. We ask for our privacy and your respect at this time as our family begins the long journey of rebuilding our lives.
