the central feature of the memorial is a dry streambed containing smooth river stones engraved with the names of victims of homicide. the stream flows from a large, granite lens, "tragic density," that symbolizes the enormous weight of sadness and grief experienced and endured by the survivors. the streambed moves through the garden and culminates in a cascade of water into a pool out of which rises "ibis ascending", a skyward sculpture representing hope. the seat walls throughout the garden, also engraved with victims' names, offer a place to sit and reflect.
