LIVERMORE – Following an extensive search that lasted more than two hours, authorities found the driver of a car that caused a head-on crash that sent two people to the hospital by helicopter Saturday morning.

Christian Brown-Barbioni, 30, of Livermore, was found hiding in a shed at his girlfriend’s home and arrested Saturday afternoon, police said. He was charged with driving without a license, an unspecified warrant out of Franklin County and aggravated leaving the scene of an accident. Deputy Craig MacMillan of the Androscoggin County Sheriff’s Office said that the final charge was elevated to a felony due to the serious nature of the accident. Alcohol was ruled out as a factor in the accident, but additional charges may be filed, pending the results of a toxicology report, he said.

MacMillan said that the crash occurred at 10:37 a.m. on Saturday. Brown-Barbioni was driving a 1999 Buick four-door southbound on Route 4 when he crossed the centerline and hit a northbound 2006 Toyota SUV driven by Wayne Bouchard, 53, of Rumford. MacMillan said that Bouchard and his wife, Joanne Bouchard, 54, were taken to Central Maine Medical Center via helicopter after the head-on collision. He said they were listed in stable condition Sunday.

The vehicle Brown-Barbioni was driving was owned by his girlfriend’s mother, Shelia Hamlin, 49, of Livermore Falls, MacMillan said. Brown-Barbioni took the car, which was not covered by insurance, without permission, but was not being charged with theft.

Amie Jacques, 33, of Rumford, that was traveling northbound behind Bouchard and was unable to stop her vehicle in time and rear-ended Bouchard’s SUV. Neither Jacques nor her passenger, Felicia Bell, 24, of Rumford, was injured.

After the accident, Brown-Barbioni took off on foot into a wooded area, MacMillan said. Authorities from the Sheriff’s Office and Maine State Police searched for him for more than two hours before locating him in a shed at his girlfriend’s home on Route 108 in Livermore — about two miles from the scene of the accident. In addition to the Sheriff’s Office and state police, MacMillan said Maine Game Wardens were on their way to assist.

“A lot of people stopped to help with the crash,” MacMillan said, thanking several people who assisted authorities and emergency personnel immediately after the accident, including two nurses and a man who helped with the search for Brown-Barbioni.
