A meth making conspiracy lands several Tri-Cities residents in federal prison.

U.S. District Judge Leon Jordan sentenced the last of seven defendants for their roles in the conspiracy. 

The group was indicted in March for conspiring to manufacture methamphetamine. 

Police say they found meth labs or meth equipment at four sites in Johnson City earlier this year.

The seven individuals include: Thomas Bugg, 52, of Johnson City, who was sentenced to 92 months in prison; James Brandon Kimes, 27, of Gray, who was sentenced to 200 months in prison; Stephen Eric Burgner, 32, of Johnson City, who was sentenced to 96 months in prison; Monroe Eugene Lowe, 27, of Jonesborough, who was sentenced to 72 months in prison; Allen Casey Story, 28, of Johnson City, who was sentenced to 60 months in prison; Carla Nicole Lowe, 23, of Elizabethton, who was sentenced to 46 months in prison; and Terra Beth Bugg, 41, of Watauga, who was sentenced to 37 months in prison.

"Tennessee continues to have one of the highest rates of meth addiction in the United States. Meth has no legitimate uses and it destroys lives, families, and communities," U.S. Attorney William C. Killian stated in a press release. "We will continue to devote resources to rid our communities of the scourge of meth by vigorous prosecution and meaningful prison terms."

The investigation involved officers from several different departments across Northeast Tennessee.
