OTTAWA–The case against two defendants arrested in an alleged mobile meth lab case in Wellsville has been continued at the request of the prosecution. A status conference hearing for 37 year old Chad McCracken and 35 year old Shawna Marie Culbertson was set for September 14 at 11:45 am. The Franklin County Attorney’s office says key evidence has not yet come back from the lab. The two defendants were arrested in Wellsville August 20 after officers say a drug dog indicated drug material was in the vehicle they were riding in.
