"Preliminary investigation shows that both speed and alcohol were factors in the accident," Police Chief Alexander Scott said in a press release Wednesday.
Luke Garlinger, 29, of Mansfield, Mass., was arrested and charged Wednesday with negligent homicide for the fatal collision that occurred shortly after midnight on Sunday.
Shellie Blaisdell of Windsor, VT., was killed in the crash. A 13-year-old male passenger in Blaisdell's vehicle, who was seriously injured, has since been released from the hospital and is recovering at home, Scott said in a press release Wednesday.
According to police, the collision occurred when a Toyota Tacoma pickup headed east on Main Street suddenly veered into the opposite lane and hit the Pontiac minivan near the Tractor Supply Store on Main Street.
Scott said Monday it appears the Toyota pickup, driven by Garlinger, was speeding at the time of the crash.
Blaisdell, who had been driving the minivan, died early Sunday morning at Valley Regional Hospital, as the result of injuries she suffered in the accident.
Her 13-year-old passenger was treated at the hospital for serious injuries.
Garlinger was taken to Valley Regional and then transported to Dartmouth Hitchcock Medical Center. He was listed in fair condition Monday afternoon, medical center officials said.
Wednesday Scott said, "Garlinger was traveling east on Main Street well in excess of the posted speed limit when the Toyota Tacoma pick-up truck he was driving crossed the double yellow line and collided head-on with a Pontiac Minivan driven by Shellie Blaisdell."
Garlinger is expected to be arraigned in the 5th Circuit Court, Claremont District Division Thursday at 10 a.m.
He is currently being held at the Sullivan County House of Corrections pending his arraignment.
