Texas Equusearch has joined in the effort to find out what happened to Jim Martin, who was last seen August 6.
Searchers using horses and ATV were out for a first day of searching Friday afternoon.
The 39-year-old Normangee resident was last seen in Normangee, though his pickup was found in Centerville on August 9. Authorities in Madison County are heading up the investigation, and have said Martin's disappearance may be due to foul play.
