HAZARD, Ky. (WMDJ) — A Perry County man charged with murder in connection to a deadly UTV crash has pleaded guilty in a separate federal case.

Court officials say 26-year-old Noah Back, of Vicco, entered a guilty plea Friday to transporting a minor across state lines for illegal sexual activity.

He faces a sentence ranging from ten years to life in prison. Sentencing is scheduled for September.

According to court documents, the federal investigation began after a UTV crash on February 28 in the Vicco area. Four people were in the vehicle, including two 16-year-old girls. One of them, Emilynn Clark, died from her injuries.

Investigators later reviewed social media posts following the crash that raised concerns about a relationship between Back and one of the surviving teens.

An affidavit states the FBI conducted a forensic interview with the minor in March. The teen told investigators the relationship began when she was in middle school and involved ongoing communication and in-person contact.

Court records also allege Back transported the minor to locations outside Kentucky, including trips to Georgia.

Authorities say records were used to verify ages and travel details as part of the investigation.

Back is scheduled to be sentenced in federal court in September. The state murder case connected to the crash remains pending.
