A former high school security guard was sentenced Friday to eight years in prison for sexual exploitation of a student at the school.
Gary Postell, 51, pleaded guilty Aug. 17 to sexual exploitation of a child and child abuse negligently causing serious bodily injury, both felonies, according to a Douglas County District Attorney’s Office news release.

The guilty plea and sentence stem from a Nov. 28, 2016, incident at Ponderosa High School. Postell, of Castle Rock, was arrested the next day.
Judge Shay Whitaker also sentenced Postell to 10 years of sex-offender probation on the sexual exploitation of a child conviction. Other charges were dismissed as part of a plea agreement.
The mother of the victim addressed the court during Friday’s sentencing.
“How sick do you have to be to attack a 15-year-old child?” she asked. My daughter “was not protected by the security guard. … Adults are obligated to look after children and take care of them, not prey on them.”
