Unicoi County Sheriff Mike Hensley said Monday night that divers went down into the quarry pond. However, due to the “murky water” and brush and trees in the water, divers were unable to find anything.

A cadaver dog was also brought in. The sheriff said the dog did alert around the pond, and they decided it was “feasible to drain” the water.

Luc Vance is a father and restaurant owner who went missing October 30.
