He interviewed the underage girl the next day, when she told him she'd given Hunt her locker combination and found the iPod in her locker on the last day Hunt was in their school.
This type of iPod allows people to exchange text messages and other media.
On some of those texts, Hunt indicated that she understood that such communications violated the court order.
"No matter what, if they find out that we talked, I'm going to jail until the trial starts," she wrote, according to Shepherd.
Pictures on the iPod showed the young couple together and a nude Hunt. There was also video of a naked Hunt touching herself in a sexual manner, the detective testified.
Authorities determined these images originated at Hunt's home in the weeks and months after the no-contact order had been issued, said Shepherd.
Graves, in her Wednesday statement, upbraided prosecutors for using frank and graphic detail in a court filing.
"What happened to a (statements) like 'numerous texts and inappropriate language' without details?" she wrote.
With the school year starting, she said, "I can only imagine the chatter at the school."
In the end, Graves wrote, two teen students were "involved in a consensual relationship."
"Yes one that under the current law is a crime, but still consensual. It was brought to an abrupt end and the older 'adult' teen faces up to 30 years in prison."
She said the younger girl "cannot comprehend the seriousness of the matter because it was something she consented to."
"Her opinion is ignored by the State," Graves said. The girl has been "interrogated by the Sheriff's Department, taken to a church that labels being gay a sin, has the Bible thrown at her, all of her things in her room boxed up and taken from her, is apparently hit by her parents, and clearly yelled at for lying by her father in the presence of Detective Shepherd at the school in a subsequent interview."
Under the circumstances, she's been confused, scared, and feels no one is listening to her, Graves said.
"She already tried to speak to Kaitlyn's mother Kelley who shut her down. So she turns to the only person who could (possibly) understand in her eyes and a person she clearly does not want to see hurt and that is Kaitlyn. She wants to try to save her and in doing so she just causes the walls to continue to tumble down."
Hunt, who turned 19 last week, was booked into detention Monday night after her bail bond company declined to secure her $5,000 bond any longer and picked her up.
Her family has not commented on the latest developments in the case.
The original charges against Hunt carry a maximum of 15 years in prison upon conviction.
Based on the newly revealed evidence, prosecutors filed a new charge against Hunt for "transmission of material harmful to minor by electronic equipment."
