After a two-day sting operation conducted by the Denton County Sheriff’s Office, a now former Denton High School employee has been arrested and a mom from another school district said she tried to sound the alarm on the educator. 

Justin Wallace Carter, 27, was among 23 individuals arrested by the Denton County Sheriff’s Office on June 14. He has been charged with online solicitation of a minor. 

According to his social media, Carter was an assistant football coach at Denton High School. Court records also revealed that he worked in the school’s special education department.

An arrest affidavit obtained by WFAA shared the details of his arrest. Undercover investigators found that Carter used an anonymous social media app called Whisper. He allegedly used the app to communicate with who he believed to be a minor for a sex act. However, it was an undercover investigator. The detective pretending to be a minor gave Carter an address to show up to. When Carter arrived he asked the minor to come out of the house, where he was met with deputies who arrested him.

Court records show that Carter is out of jail on a $25,000 bond. As conditions for his bond, Carter is not allowed to accept new employment, supervise, or participate in any program that would bring him into contact with a person under the age of 18. However, Carter “may keep his current position.”

Previously, Carter worked in Ponder Independent School District where he coached at Ponder Middle School in 2023. A mom from Ponder, Krystyn Comeaux, is now telling her story about her daughter’s inappropriate encounter with Carter. 

“I am angry because there were red flags and they were ignored,” Comeaux told WFAA.

Comeaux’s daughter, Krystyn Mahmood is also speaking out alongside her mother in case other girls were victims of inappropriate contact from Carter. 

“I want them to know it’s okay for you to speak out, it’s not a bad thing,” Mahmood said.

Mahmood recounted that Carter would walk her to class and occasionally wink at her while she attended Ponder Middle School as an eighth grader. During the last days of school, Carter allegedly pulled Mahmood aside and asked for her Snapchat. Mahmood received the friend request and Carter approached her again saying he added her on the app.

Mahmood expressed she was nervous about the incident and felt it was “really wrong.” She eventually told a close friend and the school’s principal. 

Comeaux then received a call from the principal and informed her of the inappropriate contact, and she stopped the attempted interaction before it could go further. 

“It could’ve been bad,” explained Comeaux. “It didn’t get very far. We stopped it before it developed into something. The only reason she is not a true victim is because she had a friend who was willing to speak up to protect her, to do something. That takes a lot of courage.”

A spokesperson for Ponder ISD told WFAA that Carter resigned in May 2023. 

Denton ISD also confirmed that the district hired Carter as a provisional employee in 2024, where he had worked for less than a year. 

According to Comeaux, she called Denton High School to share her daughter’s alleged story and warn them about Carter. However, she claims “nobody did anything.” 

Denton ISD told WFAA that his charge was non-school related, but failed to clarify whether Carter was terminated or resigned from his position at the school.

According to state records, Carter’s teaching certificate is valid until July 31, 2026. 

Texas Scorecard has continued to expose Texas teachers who are accused of having inappropriate contact with students.
