A Fort Collins High School teacher was arrested Thursday on suspicion of child sex exploitation and sex assault that occurred almost three years ago, according to police officials.
Detectives began investigating David Duane Miles, 48, in February and allege he began talking with a juvenile girl through a phone app, sent explicit pictures of himself to her and exchanged other explicit images in June 2022.
He met her at her Fort Collins home where they had “sexual contact,” , and she later recognized him as a teacher.
The victim is now an adult.
Detectives also served a search warrant on Miles’ phone that uncovered evidence of sexual assault, according to the agency.
In a statement, officials called the allegations “deeply troubling” and said Miles was put on administrative leave immediately after district officials found out.
“The safety and well-being of our students is our highest priority. We are committed to maintaining a safe, supportive learning environment and to responding with transparency and care,” district officials said Thursday.
Miles worked as a substitute teacher in the school district in 2001 and was hired as a teacher in 2007, Principal Jennifer Roth said in an email to families.
A since-deleted page on the school’s website lists Miles as the school’s band director and a music teacher.
Miles is facing three counts of child sex exploitation related to exploitative material and allowing a child to engage in explicit sexual conduct and one count of sex assault, all felonies, according to police.
He is being held without bond and is set to appear in court Tuesday
