Just before midnight Friday evening, Roane County deputies went to a boat ramp area on Culton Lane off Gallaher Road for suspicious activity. A K-9 was deployed to walk around eight vehicles at the scene after the smell of marijuana was detected, leading to a probable cause search. One SUV presumably had two loaded firearms, bags of marijuana and nearly $900 in cash on one subject. Deputies arrested 26-year-old Tyler Lamar Wright, 20-year-old Austin Dakota Shope, 20-year-old Hunter Scott Lee Centers and a juvenile male. Each were charged with manufacture, sale and delivery of drugs and possession of a firearm during the attempt to commit a felony.
