Accused Neck Slasher Found Competent to Stand Trial

A Moss Beach man accused of brutally sawing his high school sweetheart’s neck with a serrated knife in 2010 missed his court date six times since then because he was not medically well enough to show up.

 

Criminal proceedings continue for the Moss Beach man who allegedly sawed a 10-inch laceration into his girlfriend's neck in 2010, the San Mateo County District Attorney's Office said Monday.

David Vanalstine, 57, was scheduled for a jury trial on April 8, 2013, after a San Mateo County Court judge found him competent to stand trial based upon doctors’ reports. However, two witnesses are unavailable that date, so the case will be continued Sept. 3, 2013.

In December 2011, Vanalstine's lawyer Frank Bell asked the court for permission to receive a mental competency evaluation for his client after Bell expressed doubts regarding the 57-year-old's competency.

Vanalstine — who is facing charges for attempted murder, assault with a deadly weapon and aggravated battery — is accused of sawing his high school sweetheart’s neck with a serrated knife in their mobile home on Dec. 2, 2010. He missed his court date six times since then because he was not medically well enough to show up, according District Attorney Steve Wagstaffe.

Vanalstine had originally been scheduled for a jury trial in county court in January 2012. His case was delayed yet again as the court was yet to receive the doctors' reports about his mental competency.

Prosecutors say Vanalstine’s motive for the gruesome attack may have been connected to a DUI criminal case that was resolved on Nov. 29, 2010. His 55-year-old girlfriend called cops reporting that he had been driving while intoxicated, Wagstaffe said.

The couple had dated in high school, but later reconnected and had been sharing a home in Pillar Ridge mobile home park for the last three years. When the girlfriend came home from work one night, Vanalstine “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.

Vanalstine allegedly stopped attacking his girlfriend when the victim’s friend arrived, Wagstaffe said. The girlfriend, who was losing a ton of blood, then grabbed the phone, ran outside and called 911, he said. She was transported to Stanford Hospital, where she underwent surgery, and after receiving treatment, she made a full recovery.

Vanalstine was taken into custody at the scene, but then rushed to the hospital with medical problems unrelated to the alleged attack.

The defendant is in custody on no bail status. He faces multiple felony charges, including attempted murder and assault with a deadly weapon.

With so many good Mexican restaurants in the area, why bother?

I enjoy an occasional Taco Bell, but in the same shopping center as Happy Taco with far better,Read More authentic LOCAL Mexican food! Nah! I do enjoy the Combo locations that have KFC & TACO BELL. (Face it, Americans like to have choices!). With no drive-through, perhaps it will be better than the average suburban stores along the El Camino. As for another chain restaurant in Half Moon Bay...What did you expect? Demographics will continue to dictate that we can still expect to keep our "Fast-Food-Free-Zone" between Linda Mar and HMB while "City Councils or Planning Departments in the Cities will attract them....for their tax base.

Seriously? Taco Bell? Next to New Leaf? How did this happen? Not happy about this addition and notRead More looking forward to seeing Taco Bell trash all over the place. Not sure about KFC ... we already have a fast food chicken place at Popeyes so we certainly don't need another. The high school students will probably frequent Taco Bell the most and keep it in business but I will not be going there that's for sure.

Misha, I understand where you're coming from, but that's what we don't want to do. One reason thatRead More all dog owners are being discriminated against is those few who don't follow the rules. It doesn't matter that there are bicyclists and horseback riders who don't follow rules, they're "OK," it's the dog owners who pay the price. We want an area where our dogs can exercise freely and legally, where we won't be bothered by people who are afraid of dogs or dislike them, and where they're not at risk from horses who spook. For those of us who live surrounded by Rancho land especially, we don't want to have to drive miles to a small, fenced lot with crowds of others seeking to exercise their dogs in the same small area. We're paying for this open space with our tax dollars, and we want to have access to it. There's plenty of room for everyone.

To be honest I would probably just let my dog run around without a leash anyway, except there's soRead More much darned poison oak around these hills. I don't want her to get contaminated and then I hug her and trouble ensues.

I don't own a dog now but empathize with the dog owners who have been deprived of the right toRead More allow their dogs to run free in the national recreation area that we as taxpayers own. As a taxpayer, I want to know the rationale for this policy. If it is to protect horses from being frightened by dogs what is the basis for that? How many horses use the open space? It appears that dozens of people who have been able to enjoy walking with their dogs in the open space adjoining their neighborhood are now being grossly inconvenienced because some faceless bureaucrats are creating rules that may have no basis in reality.
