Additional charges have been filed against a former deputy with the Putnam County sheriff's office, who had already been arrested for issuing checks on a closed bank account. Authorities now say 30-year-old David Shannon Blackwell of Salem Church Road is charged with two counts of theft and one count of burglary in cases being investigated by both the Cookeville police department and the county sheriff's department. Cookeville Police Detective Tim Terry alleges that Blackwell broke into the Firestone store on S. Jefferson Avenue, and then "staged the crime scene to make it appear as if someone else had committed the burglary." He also allegedly broke into a safe at the business, making off with some $6,000 worth of cash and merchandise. Meanwhile, sheriff's Detective Shane Higgenbotham took out a warrant that claims Blackwell stole more than $7,500 worth of jewelry from his brother's home on Chimney Springs Road. That jewelery was later pawned, police say.
