A quarter-century after Columbine killings, survivors and community members gather to process...

Thirteen chairs sat on a dark chancel in the sanctuary of the First Baptist Church in downtown Denver Friday evening. A small candle was lit in each chair representing those who were shot and killed at Columbine High School 25 years ago this weekend.

Survivors, family, friends and advocates gathered in the church to honor those 12 students and one teacher on the eve of the anniversary of the tragedy in Littleton.
