On Friday, a high school track-and-field coach at Trabuco Hills High School in Mission Viejo was arrested in Laguna Niguel on suspicion of possession of child pornography, according to the Contra Costa Times. Raymond William Henry, 57, who rented a car, allegedly left what appeared to be his iPad in the car when he returned it, prompting the person who discovered the pictures of naked girls ages 11-13 to contact police on Thursday.

Members of the sheriff’s Special Victims Unit spoke to the person who found the iPad, who told them it “contained photos of naked females ranging in age from 11 to 13 years old, exposing their genitals,” KTLA reported.

In addition to the photos of the prepubescent girls, investigators also allegedly found pictures of underage girls in Trabuco Hills High School uniforms participating in track and field activities.

Orange County Sheriff’s Lt. Jeff Hallock told the Orange County Register that Henry was arrested by the Orange County Child Exploitation Task Force and Orange County Sheriff’s Department’s Special Victims Unit.

On Friday, Henry was being held on $20,000 bail and booked into the Orange County jail. His court appearance is scheduled for Tuesday.
