Workers continued to load logs onto trucks and mill about Tuesday as Catawba County Sheriff Coy Reid and about a half dozen deputies walked around outside a large metal warehouse, continuing the search for 70-year-old Ken Mohler.
The search has been focused inside in the warehouse and around the grounds.
"We've searched east and south and West. The dog will start north in a while," said sheriff Reid. "We are looking at foul play."
Mohler went missing Thursday as he was working on a waterline at G&G Lumber, and has not been heard from since. His truck was still at the lumber company Friday and a co-worker later found his truck keys and cell phone in the dirt.
Mohler's family members said that he was not the type of person to just walk off and they fear he may have happened upon a burglary and been abducted or killed.
Sheriff Reid said that two engines that were supposed to be inside the warehouse were outside when workers came to work on Friday. That has Mohler's son fearful that his father may have come into contact with someone trying to steal the engines and other items from the warehouse.
"He would do anything for anybody. If he had $20 in his pocket and you wanted it, he would give it to you," said his son Ken.
