An anonymous tip jump-started an investigation into a Douglas County sixth-grade teacher’s interactions with his students last year. Now, the man has been sentenced to a decade in prison for sexually exploiting children.
David Feil was sentenced Monday to 10 years in the Colorado Department of Corrections for child sex exploitation, a felony, which will be followed by 10 years of a sex offender , court records show.
Feil took a deal and pleaded guilty in March to two counts of child sex exploitation, dropping four felony charges of sexual assault on a child by one in a position of trust from his case, according to court records.
Douglas County School District received a Safe2Tell tip in March 2025 from a student in Feil’s class at Roxborough Intermediate School about the man sending students inappropriate videos and connecting with children on social media, police said. The students nicknamed Feil “Mr. Pedophile,” according to his arrest affidavit.
Feil had previously received a written warning about having personal relationships with students, but continued to interact with them on social media and message them outside of class, the affidavit stated.
The man was hired at Roxborough Intermediate School in 2015, became a sixth-grade classroom teacher in 2017 and was fired in 2025.
“Feil’s actions followed a clear pattern of grooming, manipulation, and abuse of trust,” 23rd Judicial District Deputy District Attorney Brynn Chase . “He targeted vulnerable students, blurred boundaries over time, and worked to keep them silent. Thanks to the bravery of these victims, his exploitation of students has been put to an end.”
Douglas County District Court Judge Daniel Warhola called Feil’s behavior “unacceptable in this community and to this court,” during Monday’s sentencing hearing, according to the District Attorney’s Office.
