Sheriff’s Deputies in Jay, Oklahoma, have arrested a 64-year-old Grove man after they found crystal meth hidden in his prosthetic leg. The man, identified as Larry Clinton Harper, was arrested at his business, which was supposed to be selling stuff completely unrelated to drugs, Harper’s Used Cars and Body Shop.

A search of Harper turned up drugs inside a covering resembling a sock inside his prosthetic leg, said Delaware County Sheriff’s Captain Larry Barnett.

“They just tumbled out, and he just laughed,” Barnett said. “He said he thought he was pulling the wool over our eyes, but we had the last laugh.”

The arrest came after successful drug purchases from Harper’s business, according to Barnett.
