Officials say Jason Landry went missing Dec. 14 on Salt Flat Road outside of Luling while he was heading home to the Houston area.
The search teams will utilize K-9s, horse mounted search crews and people on foot. They are going to visit each of the areas of interest identified when the 21-year-old disappeared.
"A lot of aerial imagery has been taken from drones," Matt Woodruff with TEXSAR said. "That imagery has been processed through an artificial intelligence system to try to identify shapes and colors consistent with possibly a missing person."

So far, there have been six major searches for Landry. The last search took place in February.
"I think they started with 4,000 to 6,000 areas of interest, and they've got it down to under 100, so that's enough to have the search teams go out and try to look at all of those at one time," Jason's father, Kent Landry, said.

Kent said he is cautiously optimistic that search crews may find something to give his family answers about what happened.
