CAÑON CITY, Colo. — Prosecutors will not file charges in a sexting scandal that involved several Cañon City High School students who shared nude photos of each other, the Fremont County District Attorney’s Office said Wednesday.

No aggravating factors were found in the investigation, District Attorney Thomas LeDoux said.

“Today’s decision does not condone or excuse the behavior of the individuals involved,” he said.

The scandal broke out last month after an anonymous tip led administrators to find more than 350 photos had been exchanged among more than 100 students.

Students shared the photos on so-called “ghost apps,” which are disguised as common applications such as calculators or sound managers. A user types in a secret code and the app then reveals a hidden screen containing photos, videos or other files.

LeDoux said there was no evidence any adults were involved or any retaliatory sharing of the photos.

Under Colorado law, any teenager who takes, receives or shares a nude photo of someone younger than 18 could have faced felony chaild pornography charges and sex offender status.

“The mere possession of these materials does constitute an ongoing crime,” LeDoux said in November. “We certainly have no intention of requiring under the law, a juvenile to register as a sex offender unless it is absolutely necessary.”
