A 34-year-old math teacher and athletic coach from a Jacksonville private school, Temple Christian Academy, has been arrested and charged with over 50 criminal counts, including the transmission of harmful material to a minor and the unlawful use of a communication device. The case began in December 2025 when a 12-year-old student reported receiving a constant stream of sexually explicit messages and images from an unknown source. Authorities traced the digital activity back to the teacher, Johnny Robinson III, who allegedly gained the victim's trust by posing as a fellow student.

Why it matters

This case highlights the growing threat of digital predators targeting minors, as well as the importance of robust cybersecurity measures and vigilance within educational institutions to protect vulnerable students. It also raises concerns about the potential for teachers to abuse positions of trust and authority.

The details

According to investigators, Robinson allegedly utilized Voice over Internet Protocol (VoIP) technology to mask his identity and generate multiple phone numbers to continue harassing the victim, even as she tried to block the numbers. A forensic sweep of Robinson's cell phone uncovered child sexual abuse material (CSAM), leading to additional charges. Temple Christian Academy has terminated Robinson's employment and stated that the current allegations do not involve any of their enrolled students.

  • In December 2025, the 12-year-old victim reported the harassment to a School Resource Officer.
  • From November 2025 through January 2026, the digital stalking and harassment allegedly persisted.
  • On April 15, 2026, Robinson was arrested and taken into custody.
  • On April 16, 2026, additional charges were added after the discovery of CSAM on Robinson's device.
