Thank you. I shared this information with the family.The family should contact Texas Equusearch if they believe she might still be in the area of the cabin (i.e.: deceased in the woods). Tim Miller has extensive experience with water searches and I believe his group would know the best way to search any swampy areas too. They won't do a search without LE's consent but they usually do try to help if the family requests a search and LE okays it (they are not only for cases in Texas, they go everywhere).
