A state appellate court panel has vacated sexual misconduct charges against a former Granite Hills High School teacher, Gerald Lopez, who was accused of engaging with a minor student in 2022. The court reversed Lopez's conviction on a child sex abuse material possession charge and a charge of child molestation, but said he can be retried for child molestation.

Why it matters

This case highlights the complexities around prosecuting teacher-student relationships, the challenges of using digital evidence, and the importance of ensuring a fair trial process that protects the rights of both the accused and the alleged victim.

The details

Lopez, who taught English and coached sports at the East County school, was arrested in 2022 by El Cajon police for what prosecutors alleged was flirtation that escalated to physical touching. Prosecutors introduced into evidence more than 8,000 texts and 930 photos between Lopez and the then-17-year-old student. However, the appellate court said there was insufficient evidence to support the child sexual abuse material conviction, which concerned a photograph the victim sent to Lopez. The panel also ruled that jurors were allowed to hear several days of "irrelevant and prejudicial testimony" from the victim, while the defense was denied an opportunity to present rebuttal evidence.

  • Lopez was convicted by an El Cajon jury in 2024.
  • The appellate court overturned the conviction on March 30, 2026.
