SIBLEY, Iowa (AP) — A 39-year-old former football coach and teacher accused of sexually assaulting a child in northwest Iowa has been convicted of a similar crime in Nebraska.

Court records say Kyle Ewinger was found guilty Tuesday of sexual assault in Omaha. Prosecutors say that in 2012 and 2013, he assaulted the 9-year-old son of a woman he was dating. Ewinger’s sentencing is scheduled for March 28.

Iowa records say the Sibley-Ocheyedan coach was fired after the district superintendent found Ewinger sleeping in his classroom next to a 10-year-old in October 2015.

Ewinger has pleaded not guilty to sexual assault. His trial in Osceola County is set to begin April 10.
