South Salt Lake detectives say a 25-year-old already accused of sexually abusing a teen is now facing fresh felony charges after investigators combed through his electronic devices and found hundreds of alleged child sexual abuse files. Prosecutors say the stash linked to Jonathan Allen Hansen includes material tied to a notorious Tennessee offender, along with videos they allege Hansen recorded himself.
New charges and alleged victims
Hansen was charged Wednesday in the 3rd District Court with aggravated sexual exploitation of a minor, a first-degree felony, and sexual exploitation of a minor, a second-degree felony. He had previously been arrested in May and charged with five counts of forcible sexual abuse involving a 16-year-old he allegedly met on social media. He was later charged in the 4th District Court with distributing harmful materials to a minor after allegedly sending explicit photos to a 15-year-old, according to charging documents and court filings cited by KSL.
Files tied to a Tennessee case
Among the hundreds of files cataloged by investigators were images described in court records as part of the so-called "Matt Estes" series, which prosecutors say circulates among collectors of child sexual abuse material. Matthew Estes pleaded guilty to producing child pornography and later received a 60-year prison sentence, according to a press release from the U.S. Attorney's Office for the Eastern District of Tennessee.
What investigators say
Charging documents allege detectives also discovered videos in which Hansen recorded himself sexually abusing a teen. After his May arrest, investigators say Hansen called the same victim from the Salt Lake County Jail and engaged in grooming behavior during a recorded phone call.
Prosecutors told the court that the investigation is still active and that law enforcement is continuing to review a large volume of images and videos taken from multiple devices. They said they expect to amend the case with additional first- and second-degree felony counts as that review continues, KSL reports.
Legal context
Under Utah law, aggravated sexual exploitation of a minor is a first-degree felony that typically carries an indeterminate prison term of five years to life. Sexual exploitation of a minor is commonly charged as a second-degree felony, with a sentencing range of one to 15 years in prison. Distribution of harmful materials to a minor is often filed as a third-degree felony, which can carry a sentence of up to five years. These ranges are set out in the state's criminal penalties guidance, according to Utah Courts.
What happens next
Prosecutors say the state will continue examining the seized files and may seek additional charges as the forensic review wraps up. Future hearings and scheduling will be handled through the district court. As of the latest records reviewed, the defense had not yet filed a public response. Authorities say they plan to release further updates as the investigation develops and new court dates are set.
