Another search for Hallman turns up nothing
Crews attempted to find clues for Matthew "Matt" Hallman by conducting a horseback patrol since the area was too vast and the weather too hot to conduct a foot search.
Investigators are also following up on a lead which indicated Hallman purchased a large amount of camping equipment from a local store on the day he disappeared.
The L-3 employee was last known to be at his Greenville residence on July 23. Hallman's wallet and other personal effects were found with his vehicle at the home.
