Johanna Justin-Jinich, a 21-year-old northern Colorado woman studying at Wesleyan University in Connecticut, was a "disciplined, fearless young woman of great promise," writes The New York Times . Her suspected killer, 29-year-old Stephen Morgan, seemed to be a "disturbed" man "with shaky relationships," a "malevolence toward Jews," and a pattern of threatening others on campus. Morgan turned himself in to police last night--a day after the campus reeled from fear following the fatal shooting of Justin-Jinich at the bookstore near campus, where she worked, according to 3 Eyewitness News  in Connecticut. Police say the two met during a six-week summer course at New York University, where Justin-Jinich filed a complaint against Morgan over harassing e-mails and phone calls--although Justin-Jinich later declined to pursue prosecution. Morgan has ties to Colorado, according to a spokesman the University of Colorado, who confirmed to 9News  that Morgan was a student in the spring and fall of 2007. Meanwhile, in Fort Collins yesterday, Justin-Jinich, who grew up in Timnath and called Fort Collins home, was remembered as a vibrant young woman who was "passionate about every living thing," writes the Coloradoan . Justin-Jinich's father is a doctor in Fort Collins and chairman of the board of directors of the Larimer Humane Society. Her mother is a doctor in Denver.
