I think the request for reward money is multi faceted.
It gets (already has if you count comments on MSM FB pages) people talking; friends, associates, family as well as the community in general. Talking provides a catalyst to jog the memory about what they have seen, heard and suspect.
It draws attention from the media. It also could provide LE with additional information by giving them another list of names to look at, both as those who donated and those who didnt, and may give them information to allow them to pursue
connections that they might otherwise not know about.
I also think the use of the word hoodlums is being used to elicit a specific response, but without truly knowing what LE does know, its difficult to speculate on what that is.
As others have already said it could be to insult the perp into making a mistake.
It could also give someone who may want to protect their own reputation from being damaged a reason to dissociate themselves with someone who may be thought of in that manor, which could lead to a change in behavior that will attract attention, leading to newfound information.
It could also be to get the local community talking about who fits the description of a hoodlum based on their interpretation of the word, and LE may hear about someones
propensity for certain behaviors that would not otherwise be discussed.
The newly released information about LE having fingerprints, hairs, fibers and other forensic evidence is, in my opinion, to make the perp extremely anxious. Anxious behavior will stand out to those around them.
The release of the information about two different weapons, and the fact that LE thinks that SDs body was not planned to be found, and especially the fact that they went back to the house for another look see is possibly to cause the perp to actually react.
That reaction could be one of many different things; dispose of the murder weapon(s), or try to put it back. Maybe move the head or check to see it has been found. Move, sell something, close a bank account, etc. Do something that will cause a big enough stir or even to entice them to ask some questions that only the perp would think about. Anything that may draw LE attention as odd or out of the ordinary.
Basically my thoughts are pretty much the same as what many have already commented on.
