I KNOW A SECRET THAT NEEDS TO BE RECORDE SOMEWHERE

Several years ago I had an office window overlooking the North end of the State Capitol grounds.  There, were trees donated to OKC from the people of Iowa commemorating the victims of the Oklahoma City bombings.  One day, probably after 5 p.m., I watched a crew dig a hole at the base of that tree memorial, place a square concrete vault in the ground and then in the vault place a large case with a plaque on the lid and they close the vault and cover it with dirt and then sod.  There were no marking place there about what was below. After the bombing there were literally thousands of small pieces of human remains that could not be identified because of contamination that preclude DNA testing.  I believe that is their burial site.
