Who Killed Deon?

A new set of videos on YouTube & Facebook from the Metropolitan Police, promoting the concept of 'Joint Enterprise':

"Joint Enterprise means that if your presence, knowledge or actions lead to a serious crime such as murder you too could be charged with murder.
You don’t have to pull the trigger or stab somebody to be charged with murder. It could be supplying the weapon or driving the killer to the crime scene knowing that something bad is going to happen.
Always think about company - who you’re with and what their intentions are, the choices you make and the consequences of not making the right decision."

Watch the first video, then watch the individual stories of each of the main players.  Can you guess who killed Deon?  & who's getting charged with murder?

(In fact you can only watch the individual videos on Facebook...)
