There are two silenced weapons. MP5 from the Colony and Bert's Beretta. Peg's has not been on guard duty. Gratuitous. So, it is important to the plot as a red herring or a piece of the puzzle. As an aside, if Hope has been killed the shooter is not likely a male. Hate to be crass, but a breeding age female is too important to lose when facing extinction.

Bill may have been the Hoarder or he may have been setup. A hoarder has lots of psycological problems. Could he steal everything and be so quick to give away his best booze?

The Rat does not have to be the Hoarder. They are two independent events. They could have been done by differenet people.

The Shooter. Again, could be independent events. But a case can be drawn for Rat/Shooter with a maller connection. A case can be made from Hoarder/shooter. The Shooter shot the prisoner and the blind girl. The hoarder could picture each as a drain on resources.

Alternatively, anyone of the above events could be a conspiracy with more than one resident. Burts armory goes off to investigate, but the shooter slips past.
