A Hill City man was sentenced Thursday in Ellis County District Court to 21 years in prison on a charge of aggravated criminal sodomy.

The sentence will run concurrent with the same sentence he received Tuesday in Graham County District Court.

Kevin Michael Cross, 25, pleaded guilty to a charge of aggravated criminal sodomy in each county for a crime that occurred between October and December 2016 involving two 9-year-olds related to him.

He is subject to lifetime post-release supervision and sex-offender registration in each sentencing.

The case was investigated by the Hill City Police Department with assistance from the Ellis County Sheriff’s Office.
