Man Arrested in Kansas & Charged with Possession of CSAM

Posted on by

Fairfax County, VA – Detectives from our Major Crimes Bureau’s Child Abuse Squad have charged a man on multiple counts relating to the possession and production of Child Sexual Abuse Material (CSAM).

Detectives from our Child Abuse Squad began investigating William Riddell, 40, of Chantilly after it was reported he may have had an inappropriate sexual relationship with a minor in Fairfax County. During the investigation, detectives uncovered electronic evidence of CSAM belonging to Riddell. The initial report of an inappropriate relationship with a minor is still under investigation.

Detectives obtained warrants for one count of Possession of Child Pornography 1st offense, nine counts of Possession of Child Pornography 2nd offense, one count of Reproduction of Child Pornography 1st offense, and three counts of Reproduction of Child Pornography 2nd offense.

On March 30, Riddell was arrested by the Salina Police Department in Kansas and is being held pending his extradition to Fairfax County.

Previously, Riddell privately taught as a music teacher in the Chantilly area. Riddell was also employed with Loudoun County Public Schools between 2008 and 2013 as a part-time substitute teacher. In 2012, Riddell was a paid Booster clinician, a non-FCPS employee, at Chantilly High School.

Detectives are concerned there may be more victims and are looking to speak with anyone who believes they, or their children, may have been involved in an inappropriate relationship with Riddell.
