The Smith County Sheriff's Department has closed its investigation of Chapel Hill ISD Superintendent Joe Stubblefield.
One of Stubblefield's employees had accused him of "abuse of official capacity." The sheriff's department says that charge was unfounded.
However, Smith County District Attorney Matt Bingham says he has requested the Texas Rangers look into another allegation against Stubblefield. The district's police department is accusing Stubblefield of tampering with documents he sent to a government agency.
