1) Alabama has criminal conspiracy and complicity laws which seem at first glance to me to make conspirators and accomplices participants in whatever crime they are conspiring to commit. You might want to try to make sense of it HERE.
2) I am uncertain what is meant in Alabama law by "causes the death of any person." Who caused the young thug's death? Was it his intended victim, his accomplices, or both?
I recall waaaay back in Criminal Law reading some cases where a defendant was convicted of the death of a co-actor, but we don’t get too many of those in my little municipal court...
