FALL RIVER — A former state corrections officer was sentenced to 3 1/2 years in state prison for selling heroin in his hometown of Swansea, the DA's office said.

Stephen Lebreux, 43, pleaded guilty last week in Superior Court to a multi-count indictment charging him with two counts of trafficking heroin and three counts of distribution of heroin, according to Gregg Miliote, a spokesman for Bristol County District Attorney Thomas M. Quinn III.

In January of 2016, Fall River Detective John Lapointe received information from confidential informants about a Department of Corrections officer who was selling heroin in and around Fall River, he said. After some investigation, investigators identified the dealer as Lebreux.

An undercover state police sergeant texted Lebreux, who agreed to meet up with him and sell him heroin, he said. Lebreux sold heroin to the undercover sergeant in the parking lot of the McDonald’s in Swansea on Jan. 27 (two bundles of heroin for $120); Feb. 2 (four bundles for $240); Feb. 10 (10 grams of heroin for $800); and Feb. 12 (20 grams for $1,600).

Lebreux was arrested on Feb. 16 on his way to sell heroin to the sergeant, according to Miliote. He was arrested with 19.46 grams of heroin to sell, and approximately six grams of heroin in his pocket and the console of his vehicle.

The case was prosecuted by Assistant District Attorney Michael Cahillane, and Judge Renee Dupuis imposed sentencing.

In addition to the state prison term, the judge also sentenced Lebreux to an additional year of supervised probation to start upon his release from prison.

“This defendant sold heroin while employed as a correctional officer. His drug dealing contributed to the serious opioid problem, and was a breach of the public’s trust because of his position,” DA Quinn said. “I want to thank the various agencies involved in this investigation for working together to bring this case to a successful conclusion.”
