Thanks for posting. The police silence as to the motives for the killing would seem to indicate Joshua was a Grand Jury Witness.
At some point someone will leak the information as to whether Joshua was or was not a witness.
Please read my post #21 for info. I’d bet anything that if he had been a GJ witness, his family would’ve known that, and would’ve spilled the beans in their grief. They believed he wasn’t into drugs. His FB page suggested otherwise.
