Rossi: When we arrived on the scene, before any of the other units got there, I could hear them. Before I even got out of the car. It was a warm morning and the windows were open in the upstairs bedroom. And their voices floated out into the street. They were crying and calling for their mommy and daddy. Three terrified children screaming for their murdered parents. I've seen so much death and pain, but it's been 20 years and I can still hear them screaming every night. Crying. If I can't tell them for sure that whoever is responsible will never do it again, that screaming might never stop.
