Colorado ? Thanks to an anonymous donor, a memorial to the 13 people killed at Columbine High School will be completed this summer.

“It’s great news. It is going to be finished in July,” Don Fleming said Sunday. His 16-year-old daughter, Kelly, died with 11 other students and a teacher on April 20, 1999. The two teenage gunmen also died.

The memorial’s total cost, including donated labor and material, is $1.5 million.

Bob Easton, chairman of the memorial committee, would not say how much the anonymous donor delivered, but the memorial’s Web site still shows it short $167,000.

Memorial organizers chose to minimize publicity about the donation because it was made, coincidentally, on April 16, the day of the Virginia Tech shootings.

The memorial, on a hill above the school south of Denver, includes a stone Inner Ring of Remembrance with a station for each of the 13 victims. Parents and siblings of victims will be allowed to post remembrances of their lost loved ones on the inner ring. Others in the community, including the wounded, will put their thoughts on the outer Healing Ring.
