I saw this on YouTube last night:
All of the perpetrators have been caught. The store owner is alive, but he is rather aged and had a heart attack, almost certainly as a reaction to this.
I think the thing that always floors me about these kinds of robberies of small markets and convenience stores is that, by design, they're not very lucrative targets for a robber. Four armed robbers for a tiny store with an aged clerk? How much money were they expecting to get?
Reservoir Dogs, they ain't. They wouldn't even be good enough for The Gang That Couldn't Shoot Straight.
