Sirois, who made his initial court appearance Thursday in Bangor, worked with his tax preparer to file false income tax returns to hide hundreds of thousands of dollars in income, prosecutors said. While Cousineau had a 50% stake in the business, the leader of the operation was allegedly Lucas Sirois, 41, of Farmington, prosecutors said. Randal Cousineau, 69, of Farmington, pleaded guilty Wednesday to conspiracy to illegally cultivate and sell more than a ton of marijuana and more than 1,000 marijuana plants, according to the documents. “The Maine Chiefs of Police Association has always stood for equal application of the laws to everyone in the state of Maine and we are confident in the next phase of the judicial system to adjudicate this case accordingly,” said Augusta Police Chief Jared Mills. The president of the Maine Chiefs of Police Association said the alleged involvement of officers was “very upsetting.” The prosecutor allegedly tipped off a corrupt police officer about the investigation, and two other officers allegedly warned the Franklin County deputies they were under surveillance, the complaint said. The Franklin County deputies accepted ownership interests and cars in exchange for confidential information, according to the complaint.
