The family of a missing SMU professor announced another widespread search four months after he went missing while hiking in Georgia.

DALLAS — Four months after an SMU Law professor went missing while hiking on the Appalachian Trail in Georgia, another widespread, professional search is planned. 

Charles Hosch, a 67-year-old Dallas lawyer and professor, was last seen on Nov. 11 descending the Appalachian Trail by two separate witnesses near the peak of Blood Mountain, according to his family. 

March 11 marks four months since Hosch initially went missing. His loved ones are planning a large-scale professional search operation on March 14 and 15.

“As spring foliage returns to the mountain, search conditions will become increasingly difficult,” an update from the team continually searching for Hosch reads. “Professional search and rescue groups familiar with both Blood Mountain and working in coordination with Union County are encouraged to join the effort.”

Hosch, a Harvard Law School graduate, is the co-founder of Hosch & Morris, PLLC, in Dallas. He is also an adjunct professor at the SMU Dedman School of Law.

His students at SMU mourned his absence in the classroom shortly after he went missing, WFAA previously reported. 

The search for Hosch has been particularly challenging due to the terrain on Blood Mountain, officials said. 

“The terrain is extremely challenging—dense brush and thick rhododendron cover obscure the ground, while boulders, cliffs, and rocky outcroppings create countless hidden space,” the search team said. “The mountain’s rugged landscape means that much of the terrain remains obscured and hard to search thoroughly, despite everyone’s best efforts.”
