The Littleton man arrested Monday on charges of child sex assault groomed his students on social media to gain their trust and “ultimately committed unspeakable acts for his own benefit,” Douglas County investigators stated in his arrest affidavit.
David Feil, 49, faces two felony charges of sexual assault on a child by one in a position of trust that stem from one incident where he allegedly allowed a student to sit on his lap while he had an erection and another where he held another child’s buttocks during a conversation, according to the affidavit.
Douglas County School District officials received a Safe2Tell tip in March from a sixth grader at Roxborough Intermediate School in Feil’s class.
The anonymous student said Feil added many boys on video game platforms and girls on social media, according to the arrest affidavit. The student also said Feil routinely sent students inappropriate videos on Snapchat, including multiple where he was shirtless or blowing kisses toward the camera.
Detectives interviewed three of Feil’s former students who were “treated differently” by the man, according to the affidavit.
Feil allegedly spoke to those students about pornography, a converstation he told them not to tell their parents about or he would “get in trouble and go to jail”; brought them gifts to school; gave them “hand massages”; touched their buttocks and friended them on multiple social media platforms, sheriff’s officials said in the arrest affidavit.
“Now, looking back at it, I understand it was weird, but at the time I just thought it was normal,” one of Feil’s former students told investigators during an interview at the Douglas County Sheriff’s Office.
Another student told detectives that Feil would pick them up, toss them and sit down with them on his lap or hold their phones above their heads and make them jump for it, sheriff’s officials said.
At one point, according to the arrest affidavit, the sixth-grade students nicknamed Feil “Mr. Pedophile.”
When the school district took Feil’s computer and searched it in March, they found photos of students in prom dresses, students wrestling and one student painting a mural on a ladder with Feil standing below.
Feil was previously given a written warning about having personal relationships with his students, specifically about having students added to his social media accounts, according to court documents.
Roxborough principal Megan Ofer told investigators Feil was given a “letter of direction” during the 2021-2022 school year that barred him from following children “on any sort of social media platform,” the affidavit stated. She reportedly described Feil’s behavior as “creeper vibes.”
Ofer confirmed Monday that Feil is on administrative leave pending the results of both the criminal investigation and an internal investigation within the school district.
A long-term substitute teacher will replace Feil in the classroom through the end of the year, Ofer said in an email to parents.
Investigators said Feil ignored the written warning and continued to follow, interact with and message the children on Snapchat and Instagram, calling them “sweetheart” and saying they “could never be replaced.”
He also exchanged texts, phone calls and video calls with students, according to the affidavit.
“Teachers are in charge of and see their children often more hours in the day than the parents do,” investigators stated in the affidavit. “The role of the classroom teacher is the ultimate position of trust, especially when students are 11-12 years old. David Feil was trusted to teach these students and instead developed personal and inappropriate relationships in which lines were blurred and ultimately crossed.”
