PARIS – No charges are to be filed in the Feb. 19 death of a Falmouth woman who was struck by another skier at the Sunday River ski resort.

District Attorney Norman Croteau said Wednesday that he had reviewed the case, and concluded that it would be impossible to prove that a crime had been committed.

“The facts were not sufficient to allow us to be able to prove beyond a reasonable doubt that the conduct was criminal in nature,” said Croteau, who handles cases in Androscoggin, Franklin and Oxford counties.

Jane McCormack, 39, died of head injuries at Central Maine Medical Center in Lewiston after being struck by another skier.

The second-grade teacher at Reiche School in Portland was standing at the intersection of Heat’s On Trail and Jibe Trail on White Cap peak between noon and 1 p.m. on Feb. 19 when a 14-year-old boy from Dover, Mass., came down Jibe Trail and struck her, said Oxford County Deputy Brian Landis. He spent eight weeks investigating the incident.

Neither skier was wearing a helmet. The boy, whose name was never released, had minor injuries.

“We have to prove either criminal negligence or recklessness, and the facts of the case simply did not rise to the proof,” Croteau said.

Assistant District Attorney Richard Beauchesne said that both he and Assistant District Attorney Joseph O’Connor had reviewed the case before sending it to Croteau.

“I believe that (Croteau’s) decision is consistent with our decision. Deputy Landis did a thorough investigation. He did a very good job, but there was insufficient evidence to proceed to the grand jury,” Beauchesne said Wednesday in Paris.

Croteau said he spoke to McCormack’s family and attorney, and shared with them the investigative findings.
