A quick search turned up another story that this young man was a drug dealer. I don’t know if that’s true or not, but...
If it’s true, then maybe he was shot for being friends with a “snitch,” or maybe he was shot by another dealer looking to eliminate the competition. How convenient to commit murder while the city is out of control.
Correction: I see that he himself fits the profile of a witness who testified. So, maybe he was shot for being a “snitch” himself, or maybe something else happened.
Joshua’s Facebook page showed several pictures of him flashing lots of cash, and in another he was blowing smoke, and the caption made a reference to “dope”. I saw this last night when I first heard about it. Now that is circumstantial that he is a dealer, but it seems like he was trying to give that impression to his friends.
