A Sioux Falls man’s jury trial on rape charges has been postponed for a third time this year. 23-year old Mason Buhl is charged with four counts of second degree rape in Hughes County. He initially pleaded not guilty to each count in September 2021 with trials scheduled for February, May, and October of this year. The prosecution requested the latest postponement. The alleged rapes took place between June 2020 and July 2021. In September 2015, Buhl shot Harrisburg High School Principal Kevin Lein in the arm. A 25-year prison sentence was suspended on the condition that Buhl follow all laws and be on good behavior. Now that case will be reopened as a result of the rape proceedings.
