Chester Clay Cox sentenced to 50 years for 15 sex crimes in Arizona

Chester Clay Cox will spend 50 years in prison without the possibility of release for good behavior after pleading guilty to 15 sex crimes in Yavapai County. The 31-year-old former Cottonwood elementary school teacher entered his guilty plea on October 26, according to the Yavapai County Attorney’s Office, bringing a resolution to a criminal case that exposed hidden cameras and historical abuse in a small Arizona community.

Based on the conditions of the plea deal, Cox pleaded guilty to offenses encompassing sexual conduct with a minor under the age of 15, child molestation, numerous counts of sexual exploitation of a minor under the age of 15, and multiple counts of surreptitious photographing or videotaping. Once his prison term concludes, if he remains alive, Cox will be required to register as a sex offender and be placed on lifetime sex offender probation.

The Investigation and Discovery of Hidden Devices

The Yavapai County Sheriff’s Office launched the investigation in June 2026 after a parent reported that Cox had molested her child multiple times between 2017 and 2020. While Cox was a teacher at a local elementary school in Cottonwood, investigators determined that this specific victim was not one of his students, and that the abuse occurred at a home while Cox was working as a youth coach.

As deputies gathered evidence on the initial molestation allegations, the investigation widened. Authorities received a tip from an alumnus suggesting that Cox might have utilized a concealed camera at the institution to film pupils while they changed clothes for athletic activities. A search of Cox’s cell phone uncovered multiple images and videos of students getting dressed and undressed, as well as using the restroom. Investigators also searched his car, recovering several recording devices, including a digital camera with tape and an antenna.

Official Reaction and Legal Framework

“Mr. Cox’s crimes are shocking and despicable,” McGrane said. “All too frequently, we hear about teachers and other trusted members of society harming children for their selfish sexual desires.”

McGrane also addressed Arizona’s current statutory limits regarding capital punishment for sex offenses against children, calling on residents to petition lawmakers for legal reform. Until such statutes change, McGrane emphasized that anyone who sexually harms a child in Yavapai County will receive a lengthy prison sentence.

Cox is scheduled to be sentenced on November 23, 2026, at 4 p.m.
