The cane was the concealed weapon(weapon concealed in the cane). It was homemade, so likely it was given to him after they put the collar on him. This suggests that there were 2 persons, with guns drawn, at the encounter that put the collar on him.

My guess is that one or more persons at the pizza place were involved with criminal types, and came up with this scheme. One had dated the bank employee, and so figured he knew enough about that bank to target it(or maybe the bank employee was in on it, too.) Having worked with the delivery guy who would end up being killed by the bomb, they figured that they knew enough about his personality to count on him reacting in a certain manner.

What I want to know is if the pizza employee who dated the bank employee was the one found dead in his home. Either way, he likely was killed by the criminal types to silence him before he ratted out the whole scheme.

The one found dead in his home apparently had a history of recreational drug abuse, and had refused medical help a few hours before he died. Perhaps the perps are drug dealers and he was client of theirs, but I doubt there's any more connection than that. Dopeheads tend to die prematurely.
