This is tragic but everyone needs to keep in mind that these two young men invented nothing. These exact crimes keep happening again and again and again.
Look up the story of Michael Russell:
CA~Michael Russell murder trial/stabbed to death by teen satanists - Websleuths Crime Sleuthing Community
Dystiny Meyers:
CA-Murder victim, 15, identified as Santa Maria girl - Websleuths Crime Sleuthing Community
A group of young Russian teens who murdered their friends:
Russian teen Satanists sentenced for murdering/cannibalizing 4 teens - Websleuths Crime Sleuthing Community
The unfortunate Elyse Pahler of San Luis Obispo:

Also an excellent overview is this story on an unfortunate boy in Carl Junction, MO in 1988. Steve Newberry just wanted to be liked. His friends just wanted to kill:

Nothing is new. The crimes and the details remain the same. If you do a search on satanic or ritual murder here on WS many more will come up. I will not be satisfied until the motive is closely examined in these cases. As it stands, even when teens admit that they were involved in the occult or satanism, it is brushed aside to get at the bare facts.
IMO, until we truly look at the commonalities of motivation and drive to commit these heinous acts by our young people, we're never going to move toward protecting future victims.
