I was looking for Maine cases regarding instances in which someone had been charged with "possession of firearms" that were actually owned by someone else; and I found a 2003 Maine Supreme Court case Maine v. Roland G. Pouliot.
The State of Maine confiscated eighty-eight firearms from the Pouliot family! The defendant's wife, Sylvia, and her son operate a discount store in Machias, Maine; and son Jamie operates a pawnshop. She confirmed that all but one gun, a black powder rifle, were returned to Jamie, who was a third party intervenor. I spoke with Sylvia Pouliot today and she said her husband did spend 90 days in county jail for the charge, but there was no fine. They hired their own lawyer, and she said costs were about $30,000.
