He refused to reveal his motives for his crimes. Nothing has ever been found to show he even knew the victims.
Judging by what I saw at the sentencing, he is cold, calculated, and has no remorse for his crimes. He didn't have the basic humanity to say anything that might help the families to understand why he did this.
At least the families had some closure, knowing he was the one that committed the crimes. No killer was ever caught in my brothers brutal murder. He was 12. No one could then, nor even now, come up with the slightest idea why he was killed.
I will never have any closure in that regards. I have, over the years, stopped living in fear, worrying about his killer coming after me.
My husband reassures me that, since no one was ever suspect and no evidence was found, that if the killer is still alive, they will stay silent and avoid any contact. Still I will wonder and will until I die, why it happened and what kind of human could do such a horrible thing, for no apparent reason. Watching the killer of the Idaho students in court, helped answer that last question, at least in part.
