It might be the first time in St. Lawrence County history that law enforcement officials dealt with two alleged meth labs in one day.
Police Chief Richard Polniak tells 7 News two residents of the duplex - Sarah Lajoy House and Victor Green - are expected to face charges.
In a separate case Thursday afternoon, sheriff's deputies responded to a reported domestic incident in the Jamison Trailer Park in the town of Canton and found what was described as "an active meth lab."
Myers was arraigned in Canton town court and taken to jail on $5,000 bail.
