Lucas Sirois, 45, and his father, Robert Sirois, 71, both from Farmington, Maine, were convicted on November 18 in U.S. District Court in Bangor of several charges related to a long-running conspiracy to grow and distribute large amounts of marijuana. The convictions followed a five-day jury trial.
Evidence presented at the trial showed that Lucas Sirois led a conspiracy from at least 2016 through July 2020. He managed the cultivation and distribution of more than 8,000 kilograms of marijuana from one industrial grow site operated through corporate entities Lakemont LLC, Sandy River Properties LLC, and Spruce Valley LLC. Each company was found guilty of operating premises for drug activities.
Robert Sirois was also convicted for his role in the operation at a facility known as the Shoe Shop on High Street in Farmington. Witnesses testified that this location produced up to 50 pounds of marijuana weekly during the period in question.
Five co-conspirators testified during the trial. One stated that over three years he bought more than 30 pounds of marijuana per week from Lucas Sirois for between $900 and $1,500 per pound and supplied it to dealers in Massachusetts and New Hampshire.
Lucas Sirois was also found guilty on two counts of tax fraud and one count of bank fraud. Testimony revealed that his tax preparer, Kenneth Allen—who had previously pleaded guilty—created false transactions among Sirois’s companies to eliminate over $400,000 in federal taxes owed for 2017 and 2018. Other witnesses said Lucas Sirois lied to a local credit union about his business activities when opening accounts used to process millions in proceeds from marijuana sales.
Robert Sirois was acquitted on one charge: possession with intent to distribute marijuana.
Sentencing has not yet been scheduled. Lucas Sirois faces a minimum sentence of ten years up to life imprisonment and fines up to $10 million. Robert Sirois could receive up to twenty years in prison and a fine up to $1 million. Sentences will be determined after presentence investigations are completed by the U.S. Probation Office.
The case advanced after an evidentiary hearing regarding the defendants’ attempt to halt prosecution; review by the First Circuit Court of Appeals upheld findings that they did not comply with Maine’s medical marijuana laws during the time period involved.
Several others have already been convicted for their roles: Randal Cousineau, Alisa Sirois, Brandon Dagnese, Kenneth Allen, former Rangeley Assemblyman David Burgess, former sheriff’s deputies Derreck Doucette and Bradley Scovil, and former prosecutor Kayla Alves (convicted in 2022 for destroying evidence).
The investigation involved multiple agencies including the U.S. Drug Enforcement Administration (DEA), IRS Criminal Investigation Division, FBI, as well as state and local partners.
This prosecution is part of an Organized Crime Drug Enforcement Task Forces (OCDETF) investigation aimed at dismantling major drug trafficking organizations through coordinated efforts among federal, state, and local law enforcement agencies.
