MECHANIC FALLS — The Androscoggin County district attorney says a grand jury is ready to begin seeing more evidence in the case of a Maine haunted hayride that turned fatal last fall.

District Attorney Andrew Robinson says the grand jury will reconvene on Tuesday and will likely meet through Friday. The grand jury has already viewed some evidence about the possibility of criminal conduct related to the Mechanic Falls hayride crash that killed 17-year-old Cassidy Charette in October.

The Oct. 11 accident at Harvest Hills Farm also injured more than 20 people. Authorities have said it appears a mechanical problem caused the accident. A Jeep towing a wagon full of passengers careened down a hill into the woods and slammed into a tree.
