The girlfriend of the gunman who killed five people and then himself at Northern Illinois University last Thursday told CNN that there was "no indication he was planning something."
Jessica Baty said her boyfriend, Steve Kazmierczak, gave no warning of the terror he planned to unleash at NIU.
"He wasn't erratic. He wasn't delusional. He was Steve; he was normal," Jessica Baty tearfully said in an exclusive interview Sunday.
Baty, 28, had been dating and living with Steven Kazmierczak for two years.
"He was a worrier," she said. He once told her he had "obsessive-compulsive tendencies" and that his parents committed him as a teen to a group home because he was "unruly" and used to cut himself.
He had been seeing a psychiatrist, Baty said, and was taking an anti-depressant to treat depression. But Kazmierczak had stopped taking the medication three weeks ago, "because it made him feel like a zombie," she said.
"He wasn't acting erratic," she said. "He was just a little quicker to get annoyed."
She knew he had purchased at least two guns. He told her they were for home protection.
On Valentine's Day, Baty was in class at the University of Illinois in Urbana-Champaign where she and Kazmierczak were graduate students studying criminal justice. The students began to talk about a mass shooting taking place at Baty and Kazmierczak's alma mater, NIU in DeKalb.
She didn't think much of it, and her mind drifted to where her boyfriend told her he would be that day -- with his godfather in another town in Illinois.
