CORNVILLE – The sole survivor of a weekend crash that killed three people has been too unstable to be interviewed by police, a Maine State Police official said Monday.

A sport utility vehicle passed some motorcycles on East Ridge Road shortly after 8 a.m. Saturday, then ran head-on into another sport utility vehicle, police said.

Initial reports blamed the crash on excessive speed and improper passing.

Police said Marc Courtemanche, 29, of Athens was the driver of a Jeep that struck another SUV at the crest of a hill.

That SUV was driven by Ralph Holt, 21, of Cornville. He and his passenger, Zachariah Holt, 14, also of Cornville, died in the crash.

Jose Holliday, 21, of Waterville, a passenger in Courtemanche’s vehicle, also was killed.

Courtemanche was flown by emergency helicopter to Eastern Maine Medical Center in Bangor, where he had surgery, according to Stephen McCausland, spokesman for the state Department of Public Safety.

On Monday, a nursing supervisor at the Bangor hospital could not provide any information on Courtemanche.

Blood alcohol tests were conducted, Lancaster said, but the results were not known Monday.

Maine State Police Lt. Dale Lancaster, who is commander of Troop C in Skowhegan, said he had not received an update Monday on Courtemanche’s condition.
