The Knox County Sheriff’s Office says a drug investigation led to two arrests this week. Deputies arrested 40 year old Johnathan L. Hall at his home on Click Hill Lane in Barbourville. Hall was charged with trafficking in a controlled substance-methamphetamine. Officers also arrested 31 year old Jessica A Webb of Pineville. She was wanted on a Knox County warrant for failure to appear on drug charges and two counts of contempt of court. Hall and Webb were lodged in the Knox County Detention Center.
