AUBURN – A Lewiston woman who handed her car keys to a man who later crashed the car on a Poland road killing six people, including himself, has changed the terms of her plea -bargained sentence.

Samantha Montana, 20, pleaded guilty in March to a misdemeanor charge of permitting an unlawful use. She was given a deferred disposition, meaning the charge will be dropped and she can withdraw her plea after a year if, in the meantime, she volunteers 100 hours of community service and steers clear of the law. At that time, she could admit to a civil infraction for her conduct and pay a $1,000 fine.

If she fails to keep clean and do the work, she could face a sentence of up to six months in jail.

Montana had agreed to volunteer at Healthy Androscoggin in Lewiston on issues of youth and alcohol. But that nonprofit group said she was unable to help out there. Montana was back in Androscoggin County Superior Court Thursday to change the terms of her plea bargain.

The Androscoggin County District Attorney’s Office OK’d a new agreement that would have Montana volunteer at American Red Cross United Valley Chapter. She presented a letter to the judge from the nonprofit organization Thursday stating that said she could volunteer there.

Montana had shared an Auburn apartment with Michael Cournoyer, 20, in 2006. She let him use her car on the night of Dec. 23, 2006. Cournoyer drove it to a party in Poland, then left with three passengers after drinking. The Nissan Altima he was driving crossed the center line of Route 122, colliding with another car. That car’s driver, Stephen Walton, 27, and his passenger and fiancee, Laura Caron, 25, were killed. Cournoyer and passengers Robert Bruce, Jacob Roy, 20, and Matthew Manley, 18, also were killed.

Police said Cournoyer’s blood-alcohol content was .14 percent at the time of the crash, nearly twice the legal driving limit. Police said alcohol was a factor in the crash.

The indictment charging Montana was later changed to specify that she let Cournoyer drive her car even though his license had been suspended.
