(WATERLOO) - A trash fire at a unoccupied house in Waterloo led to the arrest of three people on methamphetamine charges on Saturday. Waterloo Town Marshal Jay Oberholtzer says Officer Aaron Fike was investigating the trash fire in the 800 block of West Railroad Street when he detected an odor commonly associated with the making of methamphetamine. He saw two persons inside of the empty home. An active and bubbling one pot ammonia reaction vessel under pressure was also found inside of the home as well as other items required for the making of meth. Arrested on Class B felonies for dealing in meth were 21-year-old Allen Michael Johnson of Auburn, 20-year-old Shelby Lee Combs of Auburn and 46-year-old Everett Lynn Furrow of Waterloo. All three were being held in the DeKalb County Jail on a $10,000 bond. Waterloo firefighters were sent to the scene as were the Indiana State Police Clandestine Laboratory Team to dispose of the active reaction vessel and clean up the chemicals. The DeKalb County Sheriffs Department also assisted.
