California- An athletic trainer at Tustin High School has been arrested on suspicion of engaging in unlawful sex acts with a student at the school, an Orange County sheriff’s spokesman said Wednesday.

Hope Jacoby, 23, who has worked with athletes at the school for the last year, was arrested last week on suspicion of oral copulation of a minor and unlawful sex with a minor, said Sheriff’s Department spokesman Jim Amormino.

Sheriff’s deputies were informed of the unlawful acts by someone who saw a text message photograph, Amormino said. The boy was between 14 and 17 years old.

Jacoby, who lives in San Juan Capistrano, was jailed in lieu of $100,000 bail, Amormino said. Investigators believe there may have been other victims, he said.

Sheriff’s officials arrested Jacoby because she abused a “position of trust,” Amormino said. “Even though the age gap may be fairly close, it’s still illegal and we will arrest,” he said.
