A Massachusetts man allegedly stabbed his parents in a Millis restaurant on Saturday evening after apparently stabbing his girlfriend to death in a Needham apartment.
Twenty-four-year-old Benjamin Walsh is currently in custody of Millis police, Norfolk District Attorney Michael Morrissey said Sunday morning, adding that Walsh has not been charged yet in the death of his girlfriend.
The victim has been identified as 20-year-old Olivia Bergstrom of Needham.
Investigators were still collecting evidence from the third floor apartment on Marshall Street Sunday morning.
Morrissey said Millis police officers responded to a report of a stabbing at Primavera restaurant on Pleasant Street, where they found Walsh's parents suffering from stab wounds.
Jerry Gaita, the owner of Primavera, says Walsh's family was celebrating a birthday at the restaurant when Walsh showed up and suddenly attacked, stabbing his mother and father until family members could pull him off.
"I went over to where Benjamin was laying down on the floor, they had him down and Millis police arrived with EMTs."
After taking Walsh into custody, officers learned they had to do a well-being check at his girlfriend's Marshall Street apartment, which is when Bergstrom was found dead, Morrissey said.
The district attorney would not comment on how many times the victims had been stabbed.

Walsh's mother was taken to a Boston hospital, where she's still in serious condition. His father was also treated a hospital, and is in stable condition.
Walsh is scheduled to be arraigned in Waltham District Court on Monday on the charges related to the Millis stabbing of his parents. The exact charges he is facing will be announced at the arraignment.
Subsequent to Walsh's arraignment in Wrentham, he is expected to be arraigned in Dedham District Court for the Needham murder.
It's unclear if Walsh has an attorney.
