"What we do is, we start at the home and fan out from there. There are a number of outbuildings, barns, [and] that type of thing, and we have searched those time and time again and we are continuing to search everything," Williamson County Sheriff's Office spokeswoman Sharon Puckett told News 2.
Officials are asking property owners in the Rocky Fork Road and Rocky Springs Road area with trail cameras to check for images of Smithburg.
"We want to be sure if there is any piece of information, any piece of evidence out there, we want to be sure to find it," Puckett explained.
Authorities say they have no reason to believe Smithburg ran away.
"We have no reason to believe he's anything but a missing person," Puckett said when asked if Smithburg might have been abducted. "That's how we have it classified."
The Smithburg family has ties to Baton Rouge, Louisiana where Christopher attended elementary and middle school until moving to Tennessee nearly two years ago.
Authorities have reached out to Baton Rouge officials to help with the search.
"We have no reason to believe he's there in Baton Rouge or the Baton Rouge area but we are covering everything we can possible cover," Puckett said.
Smithburg's family told News 2 they are thankful for the community's support and are leaning on that during this difficult time.
A vigil will be held at Nolensville First United Methodist Tuesday at 7 p.m.
Smithburg is five feet, four inches tall and weighs 110 pounds. He has black hair and brown eyes and was last seen wearing a tan Carhart jacket, jeans and boots.
Anyone with information on his whereabouts is urged to call the Williamson County Sheriff's Office at 615-790-5550.
