My heart is broken for poor Kiaya. A sweet little girl. I watched some of her Youtube videos and they were very sad. She seemed so lonely. Almost NEVER was there a single other person in her videos. I noticed that she had a significant amount of extra weight, which often a sign of sexual abuse in a child. God only knows if the 'stepbrother' had also been molesting her or raping her. It certainly would add a motive, maybe she threatened to tell. I have sympathy most of all for Kiaya, who was only TEN years old. A young child. Very sad for all families involved, but I feel there may be much more to the story, many dark and shameful secrets, which will come to light in court. 

If the 15 year old premeditated this murder, he needs a serious amount of time in REHABILITATION, not locked behind bars. I wish they had European-style jails, working farms and programs to help offenders learn useful skills so that they can come out of confinement BETTER people, not worse. May Justice Prevail.
