Carpenter and Jacob Adam Parkey were sentenced in federal court in Greeneville for conspiring to distribute methamphetamine. Each co-conspirator pleaded guilty to conspiracy to distribute 50 grams or more of methamphetamine.
Why it matters
The sentences underscore federal prosecutors' focus on organized methamphetamine distribution networks operating in rural East Tennessee communities. For Tennessee readers, the case shows how local police work coordinated with federal task forces can dismantle multi-person trafficking operations.
All five defendants were sentenced in federal court in Greeneville after pleading guilty to conspiracy to distribute 50 grams or more of methamphetamine. Atkins will serve five years of supervised release after his 113-month term, while the seizure totals of 1,200 grams and roughly two pounds underpin the charges.

Federal Task Force Model

Its sentences fall within the multi-year federal ranges typically imposed for methamphetamine conspiracies involving 50 grams or more.
