KENOSHA COUNTY, Wis. (CBS 58) -- The Union Grove High School superintendent who is charged with possession of child pornography, appeared in court Thursday morning, Nov. 12. 

Thomas Johnson, 51, was taken into custody last week but posted bond. 

In court Thursday, Johnson waived his preliminary hearing and pleaded not guilty. 

He's facing two felonies after an investigation began in Racine County earlier this month. 

The Racine County Sheriff's Office received a letter concerning rumors that Johnson had sent inappropriate texts to students. 

While investigators did not find those messages, court records describe Johnson's two phones as "suspiciously clean," but another search of one of his phones reportedly uncovered sexually explicit photos of young girls. 

“Tom Johnson is entitled to the presumption of innocence. We’re very early in the process and we look forward to presenting his side of the story once the time is appropriate but right now, we’re very early and don’t have all of the information and we need to be able to do that," said Johnson's attorney, Patrick Cafferty. 

Johnson has since been placed on unpaid leave. He will appear next in court on Jan. 4.
