MASSACRE MADE IN USA

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 6 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. He also had a short-lived stint as a prison guard that ended abruptly when he didn't show up for work. He was in the Army for about six months in 2001-02, but he told a friend he'd gotten a psychological discharge.

On Thursday, Kazmierczak, armed with 3 handguns and a pump-action shotgun, stepped from behind a screen on the lecture hall's stage and opened fire on a geology class. He killed 5 students before committing suicide. Kazmierczak had become erratic in the past 2 weeks after he stopped taking his medication.

Kazmierczak spent more than a year at the Thresholds-Mary Hill House in the late 1990s. His parents placed him there after high school because he had become "unruly" at home. On Feb. 9, Kazmierczak walked into a Champaign gun store and picked up 2 guns — a Remington shotgun and a Glock 9mm handgun. He bought the 2 other handguns at the same shop — a Hi-Point .380 on Dec. 30 and a Sig Sauer on Aug. 6. Kazmierczak (pronounced kaz-MUR-chek) grew up in the Chicago suburb of Elk Grove Village.

At NIU, 6 white crosses were placed on a snow-covered hill around the center of campus, which was closed Friday. They included the names of 4 victims — Daniel Parmenter, Ryanne Mace, Julianna Gehant, Catalina Garcia. The 2 other crosses were blank, though officials have identified Kazmierczak's final victim as Gayle Dubowski.

We hope that this will be the last time, but, the reality goes in other way. So, where are the next victims?.
