A substitute teacher for Anderson Community Schools was arrested yesterday for a marijuana lab in her home. Kathrin Bryan and her husband are facing charges after pounds of pot and marijuana wax was found in their home. They’re suspected of extracting the THC from the marijuana to be used in other forms. Bryan worked as a sub over a dozen times at Anderson High School. She passed a background check when she began subbing nearly 4 years ago. She will not be allowed back in school due to the pending criminal charges.
