FALL RIVER —  A Fall River narcotics trafficker was sentenced to serve four to six years in state prison on Tuesday in Fall River Superior Court.

Bristol County District Attorney Thomas Quinn III says 42-year-old Michael Klein pleaded guilty to indictments charging him with trafficking in excess of 36 grams of cocaine, possession of suboxone and possession of lorazepam.

“I am pleased that the defendant has been taken off the streets for drug trafficking for up to six years,” District Attorney Quinn said.

“He has a history of drug dealing and is contributing to the drug epidemic in our city.”

In the fall of 2018, the Southeastern Massachusetts Gang Task Force received information that Klein was involved in dealing large quantities of cocaine. The task force requested and received court-authorized GPS search warrant to track Klein because of his sophisticated levels of counter-surveillance while conducting street deals.

On December 3, 2018, warrants were executed at the defendant’s stash house on Corey Street and the rental car the defendant used for dealing narcotics. Approximately 56 grams of cocaine were seized along with indicia of distribution.

The case was prosecuted by Assistant District Attorney Michael Cahillane and the state prison sentence was imposed by Judge Sharon Donatelle.

Klein will also be placed on probation for an additional two years after his release from prison.
