A routine traffic stop turned into a $500,000 drug bust in Williamson County Monday morning.
Authorities confiscated 80 pounds of hydroponically grown marijuana from California during the stop on Interstate 65 south.
It was intercepted on it's way to Alabama.
Corporal Debbie Rogers, a 20 year veteran officer, noticed the suspect driving too closely to another vehicle.
“I think he was just in a hurry to get back to where he is going,” Rogers said.
Once pulled over, 40-year-old Alabama native Oakley Simpson acted nervous as he told Rogers he was in Nashville to visit his father's grave.
His story, however, was full of inconsistencies and he couldn't give the name of his father's cemetery.
Rogers decided to run her K9, Gunner, around the car and he alerted at the trunk. Gunner is trained to sense five odors.
Rogers asked Simpson if there was anything inside his car, and he said no.
She then opened the door and immediately finds $1,400 in cash and four sealed boxes.
Simpson told her that the boxes contained candy, but once he was read his rights, he came clean.
“We don't even have to go through all this. I'm going to tell you flat out. You might as well put the cuffs on me,” Simpson said. “Marijuana is in there.”
Deputies found 71 packages of high grade marijuana inside the four boxes amounting to 80 pounds of hydroponically grown California pot.
Rogers told Nashville's News 2 Investigates that Simpson was hired to pick it up in Nashville and return it to Alabama for a payment of $2,000.
Simpson was arrested but has since posted his $100,000 bond and is out of jail.
