Overview
- Matthew Maddison, 37, who was arrested Tuesday, faces 10 counts of sexual exploitation of a minor in Summit County.
- He is being held without bail at the Summit County Jail as the case moves forward.
- Detectives say a home search turned up a large cache of child sexual abuse material on his devices, and they report he shared more than 30 files on a social site.
- The probe began March 16, 2025 after a social platform sent a CyberTip to the National Center for Missing and Exploited Children, which led Utah’s Internet Crimes Against Children Task Force to the account.
- Investigators say Maddison admitted owning the flagged social media account, and USA Climbing placed the speed team manager on unpaid leave while noting its SafeSport compliance and staff background checks.
