Three people were indicted Thursday morning at Tompkins County Court for manufacturing and possession of methamphetamine.
Beverley Stevenson, 56, Daniel Swansbrough, 34, and Brian Schmidt, 42, were arrested in Enfield on June 16 after a warrant brought police upon more than two ounces of substances containing methamphetamine.
A fourth person, Robert Farrell, 55, was previously charged with a connection to the crime.
Police say the three were also found with possession of multiple materials intended for meth-making purposes, such as sodium hydroxide, sulfuric acid and other laboratory equipment. Records show they had also been knowingly disposing hazardous materials.
All defendants were charged with second-degree criminal possession of a controlled substance, third-degree unlawful manufacture of methamphetamine, and unlawful disposal of methamphetamine laboratory material.
