Here what I see without knowing anything specific:
A. Kelvin is with 5-ish guys. They beat up a dude talking smack. We know that happened.
B. Later, some collection of the guys who beat him up come back and shoot the man dead.
C. Kelvin is not the shooter, and his defense is he had no knowledge they were coming back to do that.
This means that…
D. This is first degree murder. First degree means it was premeditated, it’s not a result of impulse in the moment. They went somewhere, then came back to search for the specific person to kill. So even if Kelvin really had no knowledge this was about to happen, he was hanging out with a dude or dudes who were In the middle of planning to kill someone.
I personally cannot fathom how you could be with a group prepping to do that and be entirely oblivious to it. Why did he think they were going back to the nightclub? The shooter needed to brandish the weapon and have it loaded before they rolled up, how does Kelvin not see this if he’s in the front seat? What effort did he make to stop the shooter?
Such a crazy scenario, I wonder how this will play out
