A married teacher in Oklahoma was arrested Wednesday after having a sexual relationship with an underage student.

Hunter Day, 22, a science teacher at Yukon High School, was arrested by the Canadian County Sheriff’s Department on complaints of second-degree rape, facilitating sexual contact with a minor and possession of child pornography, KWTV said. She reportedly is married to the school’s football coach.

Authorities said they investigated the relationship after being notified by the boy’s parents and finding explicit pictures and messages on his phone, the report said.

On the day of the arrest, the sheriff’s department said Day and the teen had planned to meet at her house, KWTV reported. Deputies arrived at the residence and reportedly texted the teacher from the boy’s phone, saying he’d arrived. Day responded to the message saying, “The doors [sic] unlocked as usual,” the report said.

When investigators entered the home, Day was sitting on the floor of her living room with candles lit and all the lights off, authorities said. She also reportedly was wearing a Christmas cat T-shirt and workout shorts.

The teacher confessed to sending the boy illicit “bra and panty” pictures and said he’d also sent her pictures of his genitals, KWTV reported.

“I’m no longer surprised by the people who commit these crimes, because predators come from all walks of life,” Canadian County Sheriff Chris West told the outlet.

“This is a classic case of a serious breach of public trust,” he said. “School teachers are entrusted to protect and educate our children, not to engage in an unlawful sexual relationship with them.”

According to a statement released on Twitter, administrators from the high school said “the safety and well-being of our students is our number one priority,” and there was no indication in Day’s record that she would make such a “very poor decision.”

The school said it was working with authorities in their investigation and couldn’t discuss details of the case, according to the post.

Day was incarcerated in the Canadian County Jail and bond was set at $85,000, KWTV reported.
