Large meth lab bust in Osage County

A Belle man faces multiple drug-related charges after authorities found a meth lab complete with an underground bunker.

Members of the Osage County Sheriff's Office and the Lake Area Narcotics Enforcement group searched the residence at 149 County Rd. 739 in Belle around 10:30 Friday night.

There they found suspected methamphetamine, other drugs and drug paraphernalia.

Further searches of the property revealed a hidden underground bunker-style room underneath one of the sheds.

Inside that underground room, deputies found around ten tanks that stored anhydrous ammonia along with numerous chemicals, components and drug precursors.

57-year-old Michael Baumgartner Sr. has been charged with manufacturing methamphetamine and two counts of possession of a controlled substance.

Osage County Sheriff Michael Dixon says that this lab is one of the largest anhydrous ammonia methamphetamine labs seized in the recent history of the Sheriff's Office.

Sheriff Dixon says investigators rarely see labs of this type due to more restrictive laws pertaining to the purchase of pseudoephedrine.
