NORWICH – The District Attorney’s Office dismissed a felony indictment against a co-conspirator in a drug case Friday and allowed her to plea to a lesser offense when she agreed to cooperate with police investigators.

Leah M. Stone, of Plymouth, pleaded guilty to seventh degree criminal possession of a controlled substance, a misdemeanor, and was sentenced to three years probation. She was originally charged with a B class felony, third degree criminal possession of a controlled substance, which could have carried a maximum sentence of 25 years in state prison.

District Attorney Joseph A. McBride asked Chenango County Supreme Court Judge Kevin M. Dowd to dismiss the felony indictment in favor of a misdemeanor offense, saying Stone “had successfully complied with all her terms.”

“To be clear Ms. Stone, like Mr. McBride has said, you did everything you needed to do, so I’m content with that,” said Dowd. “A part of this agreement is that you will truthfully cooperate in future prosecutions in the drug trade, in any form.”
