The Wilkes Sheriff's Office is investigating a couple of thefts from local houses where only prescription medication was stolen.  The first report is from John McGrady Road, North Wilkesboro.  The victim returned home to find that someone had been inside her house.  Only her prescriptions were taken from a lock box in the closet.  Then a report came in from a residence on Vannoy Road in McGrady where Sheriff's Deputies responded to a burglar alarm.  The homeowner told Deputies that prescription medications were the only things stolen in the break-in.  No suspects were listed with either report.
