A memorial for the 12 students and one teacher slain at Columbine High School seven years ago is finally moving toward construction.
On Friday, former President Clinton is scheduled to appear at a groundbreaking ceremony for the memorial in Cement Park next to the suburban Denver school.
Officials hope his visit will help raise the 400-thousand dollars still needed to build the one-point-five million dollar memorial.
Clinton helped raise 300-thousand dollars at a Denver gala in July 2004.
It has taken years to get to this point in part because parents wanted to focus first on building a new school library to replace what was the main killing field for suicidal gunmen Dylan Klebold and Eric Harris.
The memorial will include an inner Ring of Remembrance and an outer Ring of Healing.
