Androscoggin County prosecutors will consult with outside experts before deciding whether to file charges in connection with an October hayride crash that killed one teenager and injured 22 other riders.

Andrew Matulis, an assistant district attorney, said his office received a final investigation report on the crash from the Office of the State Fire Marshal around Thanksgiving, but needs more information before deciding if charges will be filed against the owners of Harvest Hill Farms in Mechanic Falls. He said his office will consult with experts outside his office and the State Fire Marshal’s Office, but declined to discuss what kind of experts or what information is needed, citing the ongoing investigation.

Matulis said all files connected to the case have been sealed and a copy of the report cannot be released.

Cassidy Charette, 17, of Oakland, was killed in the Oct. 11 accident at the popular hayride attraction. A 1979 Jeep CJ-5 that was pulling a trailer has been the focus of the investigation. Police have said the jeep went out of control while going down a long, steep hill and crashed into trees.

Matulis anticipates the District Attorney’s Office will make a decision about the case by February.
