Columbine remembered

A look back at the April 20, 1999, shootings at Columbine High School in Littleton, Colo.

Eric Harris, left, and Dylan Klebold, carrying a TEC-9 semi-automatic pistol, are pictured in the cafeteria at Columbine High School, in Littleton, Colo., during their April 20, 1999, shooting rampage where they killed a teacher and 12 students. Both gunmen later killed themselves in the school library.

Columbine students embrace as they enter the high school after a "take back the school" rally Aug. 16, 1999. With cheers and words of hope, nearly 2,000 students, many wearing T-shirts declaring "We are Columbine," returned to school for the first time since the deadly rampage.

Five months after the attack, Pat Ireland does physical therapy with Brain Trzaskos, RPT, at Craig Hospital in Denver. Ireland gained fame as "the boy in the window" after he made a life-saving plunge out of the school library. Shot twice in the head and once in the foot, Ireland landed in the arms of Lakewood SWAT team rescuers.
