DEKALB, Ill. (AP) — Steven Kazmierczak’s quiet, dependable and fun-loving exterior masked troubling details from his past that emerged as a stunned community struggled to understand what caused the 27-year-old to open fire on a class at Northern Illinois University, leaving six people dead.
A former employee at a Chicago psychiatric treatment center said Kazmierczak was placed there after high school by his parents. She said he used to cut himself, and had resisted taking his medications.
