WALTHILL, Neb. -- A 22-year-old Walthill man was sentenced on Tuesday to 4.5 years in prison for sexually abusing an incapable victim. 

The Acting U.S. Attorney announced that Kason Cline was sentenced in Omaha for one count of sexual abuse of an incapable victim. 

Cline was sentenced to four and a half years in prison and will serve five years on supervised release. There is no parole in the federal system. 

The court said the case was started in July of 2022 by the Omaha National Law Enforcement Services after getting a call from Twelve Clans Unity Hospital in Winnebago about a patient who wished to report a sexual assault. 

The Omaha Nation Tribal Police responded and spoke with the victim who said she had been drinking with Cline on the Omaha Nation Indian Reservation, when she passed out and fell asleep in Cline's bed. 

It was reported that when she woke up, Cline was sexually assaulting her. 

The court said that because the victim was asleep at the time of the sexual act, she was unable to consent or decline participation. 

A search warrant was executed at Cline's residence to recover evidentiary items related to the assault. 

Cline was interview and ultimately admitted to the assault. 

This case was investigated by the FBI.
