Law enforcement agencies were conducting a ground search for evidence in the Shelley Mook case in areas of northern Marshall and western Bedford counties Wednesday.
The areas included the Clay Hill Community of Marshall County and Haskins Chapel Road in Bedford County, according to Kristin Helm of the Tennessee Bureau of Investigation.
"We just had some information that leads us to believe that she may be in this area," Helm said. "They just have a certain area they want to cover.
"They're searching areas where cars can pull off the road, areas with river access."
State and some county agencies established command headquarters at Henry Horton State Park. Bedford County Sheriff Randall Boyce set up his search headquarters at Haskins Chapel.
TBI agents and area law enforcement personnel are looking for clues, such as any personal belongings, Helm said.
The Marshall, Bedford and Rutherford County sheriff's departments, including Rutherford County's mounted patrol, Bedford County Emergency Management Agency, Bedford County Fire Department, the Franklin County Emergency Management Agency, Henry Horton State Park rangers, including Chief Ranger Shane Petty and his bloodhound, and the Tennessee Highway Patrol participated in the TBI search, Helm said.
Mook, a reading teacher at Harris Middle School in Shelbyville, was last seen Feb. 28 as she dropped off her daughter at her ex-husband's house north of Shelbyville. Her car was found burned later that night near Murfreesboro.
A $10,000 reward is being offered for information leading to the recovery of Mook.
