Divers began searching a Williamson County pond Monday in the effort to find missing 16-year-old Christopher Smithburg, who has not been seen since Thursday morning.
The pond is located on the property where Christopher lives with his family on Rocky Fork Road.
Christopher is homeschooled, and his parents say he was doing chores when he disappeared.
Wind and rain made search conditions difficult in the first two days. On Thursday night, K-9's had to stop because of the rain, deputies said.
"We start at the home and fan out from there," said Williamson County Sheriff's Office public information officer Sharon Puckett. "That's the way we've operated the past two and a half days," she added.
More than 100 people helped in the search efforts Saturday. Teams from the Williamson County Sheriff's Office, Rutherford County Sheriff's Office, Tennessee Highway Patrol, Nolensville Fire Department, Brentwood Fire Department, Williamson County Emergency Management Agency and the Tennessee Emergency Management Agency all pitched in.
Police put out a flyer over the weekend as a way for residents in the area to help.
"We're asking property owners in the area of Rocky Fork Road and Rocky Springs Road, if they have property in that area, and they have what we call wildlife trail cameras, would they please check their cameras for images of Christopher or information that may help us find him?" Puckett requested.
The Tennessee Bureau of Investigation has opened an investigation into Christopher's disappearance at the request of the Williamson County Sheriff's Office and the district attorney's office.
The TBI says it can't say anything about the scope of that investigation at this time, only that they're also trying to find out what happened to the teenager.
Christopher Smithburg's mother, Susan Smithburg, says she wants to thank everyone for their help and support in the effort to find her missing 16-year-old son.
If you have any information on Christopher Smithburg's whereabouts, you are urged to call the Williamson County Sheriff's Office at 615-790-5550. Search efforts will pick back up early Sunday morning.
