IIRC, wasn't it Hank Jr. who took/led police to the lake near the Mondex? It seems LE focused on this area for quite some time, even finding items related to Haleigh's case in that pond. Sooo... Why would Joe P bring up the party, if it was not true? Why would Nay mention a party and iirc, she denied it occurred? Why would Hank Jr. lead LE to the pond? Imo, something happened in that area, that LE felt was credible enough to drain the whole entire pond.
