Around $30 million dollars in THC Oil is now in the custody of the Wichita County Sheriff’s Office after what could be the largest drug bust in the county’s history Thursday afternoon.

According to Wichita County Sheriff David Duke, the bust came after a traffic stop around 3:30 p.m. when two deputies stopped a silver Suburban on 287 southbound at the FM 1739 exit.

The male driver appeared to be nervous when questioned and he denied his consent to search, Duke said.

After that, authorities said the Wichita County Drug Interdiction Unit deployed K-9 Cain and he made several hits. They reported finding 12 large cardboard boxes with THC Oil weighing 680 pounds. Duke said the man is from California and was traveling from Arizona, but the suburban was a rental car from Amarillo. Investigators believe the driver was headed to Dallas or Houston.

He will be charged with manufacture and delivery, a first-degree felony. His name has not been released.
