A Moss Beach man who sawed his high school sweetheart's neck with a serrated knife in their mobile home more than two years ago was sentenced to 15 years to life in state prison on Tuesday after pleading no contest to several related charges, prosecutors said.

David Vanalstine, 59, was denied probation in connection with the savage attack Dec. 2, 2010 that left his former girlfriend with a 10-centimeter laceration on her neck, San Mateo County District Attorney Steve Wagstaffe said.

Prosecutors believe the abusive Vanalstine, who had been living with victim in the Pillar Ridge mobile home for three years, was enraged that the victim had reported him to police for driving under the influence. On the day of the attack, he reportedly waited for the victim to return home from work.

Valastine “came from his room, pulled out a knife, held her down on the couch by her hair and began sawing at her neck with the serrated knife,” Wagstaffe said.

The attack stopped when the victim's friend arrived, allowing the victim, who was losing massive amounts of blood, to grab the phone, run outside and call 911, Wagstaffe said.

San Mateo County sheriff's deputies initially described the woman's injuries as life threatening. She underwent surgery at Stanford Hospital and luckily survived the attack.

Valastine's blood-alcohol level three hours after the attack tested at a whopping .59, well above the state's .08 legal limit, Wagstaffe said.Bay Area NewsCrimeCrime & CourtsDavid VanalstineMoss BeachSteve Wagstaffe
