CLEVELAND COUNTY, Oklahoma - Charges were filed against a former Norman High student accused of raping an unconscious classmate.

Tristen Killman-Hardin, 18, was arrested Tuesday and booked into the Cleveland County Jail.

The 16-year-old alleged victim told police she was intoxicated and got a ride with Tristen after a party.

She said she remembers very little after that, but an affidavit said Tristen raped her in his truck and recorded it. According to court documents, “a short time later via her phone and social media, the victim received a copy of a video that appeared to depict her being sexually assaulted in Killman-Hardin's vehicle.”

Rape allegations led to several protests by students who feel Norman Public Schools did not take appropriate action.

So far, three young ladies came forward accusing Killman-Hardin of raping them while they were under the influence of drugs or alcohol.

“We were confident that they were going to have enough evidence to bring charges,” said Stacey Wright, with the protest group, ‘YES ALL DAUGHTERS.'

Student-led group ‘YES ALL DAUGHTERS' has been relentless in its fight for justice.

“Everybody is really relieved tonight,” said Wright. “Overwhelming relief.”

Killman-Hardin was charged with two felony counts of first degree rape of his unconscious 16-year-old classmate.

In an audio recording obtained from news website ‘Jezebel,' Killman-Hardin admitted to a friend that he “had sex” with the teen after a party the night before.

Friend: “So she was down with it at first and then like when you went to her…”

Tristen Killman-Hardin: “No, she wasn't.”

Friend. “At all?”

Tristen Killman-Hardin: “No.”

Friend: “At all.”

Tristen: “She was asleep. I was just like… she was like incoherent. Like you could not talk to her at all. She was like, **inaudible.** I was like alright. (explicit audio) I don't know how to explain it, it just happened, she passed out.”

“There's a long, long road ahead with the criminal prosecution and that's going to be an emotional process for these families, and these girls as well,” said Wright.

No word at this time when or if charges will come down in the two other rape cases.

Norman police said those investigations continue.
