AUBURN — A Maine grand jury is expected to decide by July 8 whether criminal charges should be brought in relation to a fatal haunted hayride.

Androscoggin District Attorney Andrew Robinson says the jury will reconvene for a third session on July 7 and wrap up the following day. The jury is weighing the possibility of criminal charges stemming from the death of 17-year-old Cassidy Charette. She was killed during a haunted hayride at Harvest Hills in Mechanic Falls last October.

The accident also injured more than 20 people. Authorities have said it appears a mechanical problem caused the accident.

The grand jury first met on the case in May and held a second session in June.
