But several schools in Colorado and other states were closed by perceived threats of violence, and a student in Ottawa, Canada, stabbed four classmates. The motive was unknown. At Clement Park, one man dressed in camouflage was asked to leave, but the memorial ceremonies were otherwise held without incident or arrest. About 11,000 people came to the park throughout the day and night, a much smaller turnout than school and law-enforcement officials had anticipated. Rick Kaufman, a spokesman for Jefferson County schools, said the projected crowd of 100,000 was based on the number who commemorated the first anniversary of the Oklahoma City bombing.
Many people mark the anniversary in their own way.
The names of the killers were not mentioned during the remembrance ceremony. After the massacre, memorial crosses were temporarily erected on Rebel Hill, the grassy summit in Clement Park overlooking Columbine High. He left 15 roses - 13 white and two red. At Chapel Hill Memorial Gardens in Littleton, where three of the victims are buried, balloons were released in the name of hope. My hope is that Columbine will not only be known for tragedy, it will also be known for triumph.
