12 hours after Holly was abducted the searches began. They began with a 5 mile square area using canines, ATV's, Air, horseback, and on foot. For the next 4 weeks searches continued in different areas.
New equipment was used in her search. The Tennessee Wildlife Resource Agency began using site-imaging technology to look for clues in local lakes and bodies of water.
Looking at the search maps it seems like they skipped around during the searches and possibly skipped some areas. I don't understand searches so I'm probably wrong but I'd love the hear from someone who knows how they knew where to search, why they would change directions in a search, and how effective ATV's, horses, and Air searches were/are in dense wooded areas.
What were they seeing during the search that led them to change directions?
