DEKALB, Illinois (CNN) -- Eric Mace says he thought he was giving his daughter good advice by asking her to sit up front in class. Ryanne Mace was 19 when she was killed last year in a shooting rampage at Northern Illinois University. "I'd like you to sit in the front row of every class that you're in and constantly drag information out of these people, and if you don't understand what they're talking about, raise your hand and say, 'I don't get it' until you get it," Mace recalled telling her. His daughter, 19-year-old Ryanne, took that advice. Now, he wishes she would have sat somewhere else.

Because @placeholder had not been in a mental facility for more than five years, he was legally able to purchase those weapons in Illinois -- and on the firearms application form Kazmierczak filled out, he stated that he had never been adjudicated "mentally defective" and had never been "committed to a mental institution."
