South Carolina Attorney General Alan Wilson has announced the arrest of River Allen Mathis, 26, from Cayce, South Carolina, on a charge related to the sexual exploitation of minors. The Lexington County Sheriff’s Department, part of the Internet Crimes Against Children (ICAC) Task Force, carried out the arrest with assistance from investigators in the Attorney General’s Office.
Authorities report that a CyberTipline alert from the National Center for Missing and Exploited Children led them to Mathis. According to investigators, Mathis is accused of distributing files containing child sexual abuse material.
Mathis was taken into custody on July 31, 2025. He faces one count of sexual exploitation of a minor in the second degree (§16-15-405), which is classified as a felony and carries a potential penalty of up to ten years in prison.
The Attorney General’s Office will prosecute this case.
Attorney General Wilson stated: “All defendants are presumed innocent unless and until they are proven guilty in a court of law.”
The term child sexual abuse material (CSAM) is now used instead of “child pornography” because it more accurately describes materials depicting abusive crimes involving children. The older term can suggest consent by minors, which is not possible; thus, CSAM has become standard language globally for these offenses.
