SULLIVAN COUNTY, Tenn. -

Sullivan County sheriff's investigators say a meth maker was using the national forest as a place to dump meth labs.

The dump site was found along Big Creek Road.

"During the search they found several different dump sites," said public information officer Leslie Earhart. "There were two that were larger than the others. Total, there were about nine one-pot cook bottles located, as well as around 30 gas generator bottles, and numerous items used in the meth-making process.

Earhart tells us detectives, working with the U.S. Forest Service, are following up on some evidence they found at the scene of one of the dump sites.

The sheriff's department has an ongoing investigation into who is responsible for dumping the labs.
