Man allegedly held teen captive in basement, forced her to remove braces with pliers after Snapchat meeting

The missing Utah teenager found alive in Oregon nearly 18 months after her disappearance was allegedly beaten repeatedly and forced to remove her braces with pliers to hide her identity, according to disturbing new details in the case.

Kylie Arellano, now 17, vanished from Garden City, Utah, on May 29, 2025, when she was 15. Federal authorities have now charged a 39-year-old man in her alleged captivity.

In court documents reviewed by Fox News Digital, Adam Hunter Harmel allegedly became "very violent and aggressive, often hitting" the teen and further forced her to remove her braces with pliers so that she could not be identified.

The federal complaint also paints a chilling picture of captivity inside Harmel's home, where Harmel allegedly confined the teenager to the basement, where the two shared a bed.

To prevent her from escaping, the complaint says, Harmel also "kept a knife under his pillow and made MV [minor victim] sleep against the wall."

Investigators said Harmel had expressed a desire to start a family with the teenager, stated that he was interested in minors and repeatedly sexually assaulted her in 2025 and 2026, according to the complaint.

Harmel allegedly transported Arellano across state lines with the intent to engage in criminal sexual activity.

That wait ended Nov. 1, when law enforcement rescued the teenager from a home in Oregon following a tip from the parent of another player of the online game "Among Us."

According to an affidavit written by FBI Special Agent Andrea Elder, Arellano's family first reported in 2025 that she had been groomed online, with communications beginning on gaming platforms before moving to other social media apps.

According to a law enforcement source, the suspect allegedly before her disappearance.

During the investigation, the FBI also learned that Arellano was allegedly groomed on platforms that are often used by Nihilistic Violent Extremist (NVE) Groups members to solicit sexually explicit photos and maiming photos, according to a release issued by the Department of Justice (DOJ).
