BOSTON — A Fall River woman who was formerly married to an inmate in a Massachusetts prison has pleaded guilty to being part of a drug smuggling scheme.

The Massachusetts U.S. Attorney's Office says Lisa Guillemette, 42, of Fall River, pleaded guilty Tuesday in U.S. District Court in Boston to one count of conspiracy to distribute Suboxone and Alprazolam. Guillemette will be sentenced on August 22.

In September 2018, Guillemette was charged along with her ex-husband, William Guillemette, 39, and Chad Connors, 42, both inmates at Massachusetts Correctional Institute - Cedar Junction in South Walpole. Guillemette's former mother-in-law, Margaret Guillemette, 58, also of Fall River, was charged as well.

William Guillemette and Connors were inmates in MCI-CJ's Departmental Disciplinary Unit. Connors was romantically involved with a nurse in the unit, Christine Ramos. Ramos agreed to Connors' request to smuggle contraband, including drugs, into the prison by receiving them from Lisa and Margaret Guillemette in P.O. boxes that Ramos had to set up through a third party. Connors sent letters and money to Ramos at the P.O. boxes, with Lisa and Margaret sending Suboxone and Alprazolam to the P.O. boxes. Ramos would smuggle the drugs into the Departmental Disciplinary Unit and deliver them to Connors who, with William Guillemette, would distribute the drugs to other inmates. Connors would then send checks to Lisa and Margaret Guillemette as payment.

William and Margaret have already pleaded guilty to charges they face in connection to the case. They await sentencing. Ramos has been sentenced to two years of probation after she pleaded guilty to one count of conspiracy to distribute Suboxone and Alprazolam.
