Columbine honors 13 lost with community service, ceremony

LITTLETON, Colo. — Community members in suburban Denver marked the 20th anniversary of the Columbine High School shooting Saturday by volunteering at shelters, doing neighborhood cleanup projects and laying flowers and cards at a memorial to the 13 people killed.

A remembrance ceremony was planned for later in the day. The events end a three-day slate of somber gatherings honoring the victims and lending support to their families, survivors of the April 20, 1999, attack and the school’s students and staff.
