Etowah County investigators have joined the search for a missing Pickens County woman. Christy Lynne Cook has not been seen nor heard from since last Tuesday afternoon. The man she was with, Anthony McClellan was found disoriented and taken to a local hospital where he was treated and released. The black GMC truck they were in was recovered Friday near Stephens Gap Road in Etowah County, but an Excel ski boat that was believed to be attached to the truck has not been found. Cook is potentially in danger and law enforcement encourage anyone with information to contact local authorities.
