NORMAN, Okla. – A convicted rapist is back in jail after he violated his probation.

Now, a petition has been launched, calling for Tristen Killman-Hardin to go back to prison.

It’s been nearly two years since the emotional protests outside Norman High School.

That’s when the ‘Yes All Daughters’ movement began.

Students and families called for justice after a videos surfaced of Killman-Hardin sexually assaulting a 16-year-old girl inside a car.

The victim was allegedly raped twice while she was unconscious.

It happened after she’d been drinking at a party and accepted a ride home from Killman-Hardin.

Prosecutors charged him with two counts of first degree rape.

He pleaded no contest last year and went to prison.

People in the community were relieved.

But, now, he’s free and a registered sex offender.

That’s why police arrested him last week for entering a safety zone around Norman North.

Killman-Hardin reportedly told police he was waiting for a friend.

He’s out of prison because eight years of his 10-year sentence were suspended.

He did 85 percent of his time and got out.

Now, a petition is up, calling for Killman-Hardin to be sent back to prison for the full 10 years.

The ‘Yes All Daughters’ founders launched it, writing this:

“We are outraged that his punishment did not fit his crimes. Killman-Hardin is a serial rapist and a danger to our community. We demand he serve the remainder of his sentence.” – Yes All Daughters

District Attorney Greg Mashburn told NewsChannel 4 he’ll look at the case this week and plans to ask a judge to put Killman-Hardin back behind bars.

Killman-Hardin is in the Cleveland County jail on a $25,000 bond.
