A father-son duo were convicted of conspiring to distribute marijuana as part of a multimillion-dollar ring in western Maine.
A 12-person jury returned a guilty verdict late Tuesday night for all counts against Lucas Sioris, the leader of the conspiracy. It returned one guilty and one not guilty verdict for Robert Sirois, the father.
Lucas Sirois was found guilty of conspiracy to distribute marijuana; conspiracy to defraud the U.S. and impede and impair the Internal Revenue Service; bank fraud; and tax evasion.
Robert Sirois was found guilty of conspiracy to distribute marijuana and not guilty of possession with intent to distribute controlled substances.
The conspiracy charge each man faced involved more than 1,000 kilograms of marijuana, according to the jury’s verdict.
The guilty verdicts are for the last two people who were part of a conspiracy to sell pot illegally in Maine that ultimately led to charges against 13 people in 2021. A local selectman, an assistant district attorney and two former Franklin County Sheriff’s Office deputies eventually pleaded guilty to felonies as part of the scheme.
Multiple people who had pleaded guilty testified during the trial. Lucas Sirois’ defense argued during the four-day trial that he was growing hemp, not marijuana. The U.S. Attorney’s Office called that “revisionist history.”
The jury also returned a guilty verdict of maintaining a drug-involved premise for businesses Lakemont LLC, Sandy River Properties LLC and Spruce Valley LLC.
Lucas Sirois remains in custody of the U.S. Marshal Service until his sentencing. Robert Sirois will remain out on bond.
