CAMERON, Mo. (AP) — A Cameron teacher and volunteer has been charged with child sex crimes.

William “Derek” Williams, of Cameron, was charged Wednesday with statutory sodomy and three counts each of possession of child pornography and sexual exploitation of a minor. No attorney is listed for him in online court records.
Williams worked with Cameron High School’s multimedia class for one hour a day. He also directed school musicals and plays.
According to the Clinton County Sheriff’s Office, on Sept. 6, a report was taken from a victim which opened up an investigation against Williams.
School District Superintendent Matt Robinson issued a statement Wednesday.
“The Cameron R-1 School District was notified today of serious charges filed against W. Derek Williams. At the time the District first became aware of this matter, an immediate and thorough investigation was done, and the District has determined that there is no evidence that any alleged acts were perpetrated on District property. We want to assure our staff and students that we responded to the allegations appropriately and we have fully cooperated with law enforcement’s efforts in this matter. We will continue to do so as this matter proceeds. Since the time we became aware of allegations, Mr. Williams has not been on District property and will not be permitted to return. Although we are limited in what we can say about individual personnel matters, above all else, we want to assure you that the safety and well-being of District students is our primary concern. Should your student require support of any kind, the District’s counseling staff is always available. Likewise, please do not hesitate to contact Dr. Matt Robinson should you or your student have any questions or concerns.”
Earlier this month, Robinson put Williams on administrative leave, pending the Clinton County Sheriff’s Office investigation. Robinson says a process will now start with the Board of Education to determine Williams’ future with the district.
Williams also volunteered at several community organizations, including Camp Quality Northwest Missouri, a camp for children with cancer.
