The Maine truck driver whose tractor-trailer last summer struck the rear of a YMCA van, killing a 12-year-old Westport girl on board, has lost his appeal of a three-year suspension of his drivers' license, according to the Kennebec Journal, a Maine newspaper.

State officials in Maine on Tuesday upheld the decision to suspend the license of Charles Willey of Dexter, Maine.

Tess Meisel died last Aug. 17 when the tractor-trailer truck Willey rear-ended the van in which Meisel was a passenger on Route 2 in Farmington, Maine. The Westport girl, a Coleytown Middle School student, was the only person killed in the crash. Two other campers in the van, including fellow Westporter Samantha Galvao, survived the accident and reportedly did not suffer serious injuries.

The YMCA van was traveling from Acadia National Park in Maine to a park in Vermont, according to Farmington police.

Willey and his lawyer, Thomas Marjerison, argued at a May 31 hearing that the suspension should be lifted, according to the Kennebec Journal.

But Maine Bureau of Motor Vehicles hearing examiner Frank Naiman disagreed, stating in a written decision that Willey "negligently operated a motor vehicle in a manner so as to cause the death of another person," according to the Kennebec Journal.

Willey has 30 days to appeal the hearing examiner's June 21 finding to a Maine superior court judge, the newspaper's article added.

No criminal charges were filed against Willey in connection with the crash.
