Quick question I came across a while ago the men dead laying on truck and ground with “jason” hockey masks on …who are they and how do they fit in …were they robbers as the truck has a bunch of safes in it armour truck robbery type thing ?? can someone shed light on this query please :smiley:

Robbery gone bad in the first hours of the Fnix Uprising.
Any survivors were eventually killed by the machines, but it seems both parties died from bloodloss in the spot.
