LOOKOUT VALLEY, HAMILTON COUNTY (WRCB) - Deputies are following up on a fresh lead in a six-year-old cold case.

Investigators are conducting a ground search at 1580 Canyon Road, where human bones were discovered in December 2004.

Forensic analysis determined the bones belonged to 33-year-old Melissa Ward, who was reported missing by her family on November 2, 2004.

The Hamilton County Sheriff's Office says interviews are being conducted with persons of interest.

In December 2005, a couple shopping for a plot of land near the Tennessee River found the body of Ward in a remote area.

Ward had several run-ins with the Chattanooga Police Department for prostitution and drug charges.

Ward's disappearance and murder were the subject of a January 2004 Crime Stoppers.
