MENTONE, Ind. (WOWO): Two people are in jail after Indiana Conservation Officers discovered meth-making materials in Kosciusko County.

As an officer was patrolling areas of the Tippecanoe River in Mentone, 20-year-old Christopher Carroll and 21-year-old Shanelle Byrer were found with materials in their vehicle that are known as precursors to producing methamphetamine.

Carroll and Byrer sped through a stop sign and when the officer pulled them over, he found meth in the car, as well as chemical reagents, such as Pseudoephedrine.

Police say the ingredients are used in the “one pot” method of cooking methamphetamine.

Both Carroll and Byrer are currently on felony probation for methamphetamine related prior arrests.
