Student stabbed in Colorado high school

A 14-year-old boy calmly walked into the entrance of Montrose High School in Montrose, Colo., Tuesday morning, grabbed a girl from behind and slit her throat in front of her sister and dozens of classmates. The sophomore girl, Mallory Haulman, 17, underwent several hours of surgery and is now recovering in an area hospital. By Tuesday night, teary-eyed fellow students gathered outside the hospital, held up lit candles and chanted, "Mallory, we love you." The suspect in the apparently random attack is being held in a juvenile-detention facility for investigation of first-degree assault
