Three people are accused of manufacturing methamphetamine in a residence less than 2,000 feet from Rebecca Boone Elementary School.Truesdale police said Michelle L. Cameron, 42, Mary Lucrezia Long, 41, and James W. Martin, 29, Truesdale, were arrested when police executed a search warrant June 1 at 7 a.m. at their home in the Belaire Trailer Park.Police located a variety of chemicals used to manufacture methamphetamine, including liquid camp fuel and a glass jar containing “an unknown solvent.” Police also found at least one coffee filter containing a substance that tested positive as methamphetamine.Checks of a database that tracks sales of pseudoephedrine, a medication used to make methamphetamine, showed that each suspect had multiple recent purchases.All three are now charged with manufacturing a controlled substance, a Class C felony that can carry a three- to 10-year prison sentence if convicted. Cameron also is charged with felony drug possession and possession of drug paraphernalia.All three have hearings set for June 14 at the Warren County Circuit Court.The sale of pseudoephedrine is monitored through the National Precursor Log Exchange (NPLEx), a real-time electronic logging system used by pharmacies and law enforcement to track sales of over-the-counter cold and allergy medications containing precursors to the illegal drug methamphetamine.NPLEx, coupled with the work of law enforcement officers and retailers across the state, is one of the many reasons that there has been a consistent decline in meth labs in the state of Missouri.Michelle CameronMary Lucrezia LongJames W.
