Sheriff’s deputies responded Saturday morning to the home near Rockford after Ruckman’s ex-wife reported she wasn’t able to contact him. They found the two boys shot in separate bedrooms, while the man was in a third bedroom

The Rockford Register Star reports Ruckman was a long-time political science professor at Rock Valley College and an instructor at Northern Illinois University. Ruckman last taught a course at NIU in spring 2017, said Lisa Miner, senior director of communications for the university.

The boys were both students at Rockford Christian schools.
