According to officials, at approximately 4:30 p.m., Monday, residents of Northview Country Estates called the sheriff's department regarding a "strange odor," in the area.
Officials said residents in the area had smelled the odor before, but it was more "isolated" Monday.
Deputies said they eventually narrowed it down to Lot 4.
Officials stated after several attempts to get someone to open the door to the mobile home, the occupants eventually exited the residence, when deputies also noticed a "cloud of smoke" coming from the home.
The investigation led deputies to discover more than one methamphetamine lab inside the mobile home.
According to officials, several items were allegedly discovered inside the home, which were consistent with the manufacturing, possession and ingestion of methamphetamine.
Officials then arrested Jerry D. Wells Jr., 34, Terre Haute, and Malena Shumaker, 29, Brazil.
Both were preliminarily charged with Manufacturing/Dealing Methamphetamine (a class B felony) and Possession of Methamphetamine (a class D felony).
Shumaker was also preliminarily charged with Maintaining a Common Nuisance (a class D felony).
As of Tuesday afternoon, both Shumaker and Wells were still incarcerated at the Clay County Justice Center. Shumaker was being held on a $25,000 bond, with no 10 percent allowed, while Wells was being held on a $50,000 bond, also with no 10 percent allowed.
The alleged methamphetamine lab was processed and handled by members of the Indiana State Police Clandestine Methamphetamine Laboratory Team.
Other agencies responding to the scene included the Brazil Police Department.
