A security officer at Ponderosa High admitted to touching a student in a bathroom in the school’s athletic complex, according to court documents obtained by 9Wants To Know.

Gary Postell, 49, was arrested on suspicion of three counts of sexual assault on a child and was suspended without pay by the Douglas County School District, where he has worked since September 2014.

According to an arrest affidavit, the girl went to the hospital with her mother after alleging that she was sexually assaulted. When she was interviewed there, she told a detective that she and Postell were shooting hoops in a gym when he started making comments about her body.

The two then retreated to a darkened area of the gym, where the girl said she allowed Postell to touch her and that he also exposed himself to her.

Later, the girl told the investigator that Postell sent her a message through Facebook and told her to meet him in the gym hallway at noon. She then said she went with him to the bathroom where he allegedly touched her again.

The girl showed investigators text messages on her phone and then agreed to send him a message while detectives were with her.

She wrote: “are you there baby” and it was answered shortly thereafter by “I’m here. What cha doin” – a message allegedly sent by Postell.

The two exchanged several more messages while the girl was in the presence of detectives.

Later that night, according to the affidavit, Postell was questioned by investigators and alleged that the girl exposed herself to him and that she tried to get him to touch her.

“Nothing happened today,” he said.

Eventually, according to the affidavit, he acknowledged that the two went into a bathroom near the gym and admitted that he touched her.

Postell was released after posting $5,000 bail. He is scheduled to return to court Jan. 6 for a decision about the formal filing of charges.

“This allegation is certainly concerning and we take any reports of this nature seriously,” said school district spokeswoman Paula Hans. “Douglas County School District does not tolerate inappropriate staff conduct towards our students. Due to privacy laws and the law enforcement investigation surrounding this allegation, we are unable to discuss this matter specifically.

“However, if we receive allegations of this nature, we immediately contact law enforcement, begin our own investigation and possibly place the staff member on administrative leave during the investigation. We do not condone any inappropriate staff conduct, and we cooperate fully with our law enforcement partners.”
