A former Wanette math teacher charged in April after deputies investigated complaints involving inappropriate text messages with a student appeared in court Wednesday and pleaded not guilty.

Charles Clay Dawson, 43, of Purcell, is charged in Pottawatomie County District Court with felonies of instigating sexual conduct with a minor by use of technology and possession of juvenile pornography.

In the first count, Dawson is accused of engaging in communications with a minor. For the possession of juvenile pornography count, he is accused of having digital images on his cell phone of a child under 18.

Both counts are alleged to have occurred between March 22 and March 31, at which time Dawson taught 6th through 11th grade math classes. Deputies confirmed he formally resigned his teaching position at Wanette in April.

Dawson entered the not guilty plea before District Judge John Canavan; his next court date is scheduled Oct. 27.

Back in April, Pottawatomie County Sheriff Mike Booth said his office launched an investigation when a 16-year-old Wanette student reported incidents involving text messages with her teacher.

According to court paperwork, the student told deputies that through instant text messages on a social media application called KIK, Dawson, her teacher, asked her to send him nude pictures of herself.

The affidavit shows the teen used a cell phone provided by Dawson to take pictures of herself while at her home.

The teen, who indicated Dawson made the request twice, told authorities she sent two nude pictures because she was afraid the teacher would fail her in class if she didn’t.

As part of the ongoing investigation deputies interviewed Dawson Wednesday at the school, with Dawson allegedly admitting that he asked the teen for the nude pictures and that he looked at them on his phone before deleting them.

The document also shows he allegedly received three nude photos from another 15-year-old student that he looked at but didn’t request.

Dawson told investigators that he had been messaging both students on his personal cell phone through the KIK app, the paperwork shows.

“Charles Dawson admitted that he knew these actions were wrong but did not report the incidents to anyone or any authorities,” the investigator’s affidavit reads.
