7) Vampyre-Slayer? News reports are coming in, from all across town, that someone is shooting up the place with the
strangest weapons!... The perpetrator hasn't been seen, but odd things have been turning up, like piles of dust with rumpled clothes, penetrated by a multitude of broken toothpicks... Other incidents have involved blasts of silver, as if from a shotgun, laced with garlic; broken glass; bloody two-by-fours sharpened to a point; some odd sorts of crossbow bolts; wooden 9mm slugs, and... wheelchair tracks?
If the PCs cant figure it out, some more modern-day do-gooder is also battling the overbites, but doing it with firearms, infrared night vision scopes with IR, explosives, a wheelchair, and a VERY bad attitude! Can the PCs find him before the cops and/or the vamps do?
If not, headlines will appear, from a few days to a few weeks later, detailing the rantings of a newly-arrested "crazy old man" who claims that vampires are common place in the city, and turn to dust when "toothpicked". The police will be very hush-hush about his methods, and the PCs will be unable to get in to see him, or his equipment... which (oddly enough) seems to have been "misplaced" by the Evidence Room!
A week or two after that, the "crazy old man" will "disappear during transport", becoming a two-week wonder, and then be forgotten...
By everyone except the Initiative, that is! They have "acquired" him, using his inventiveness to help along their weapons program, and he has used them to learn new and better ways to kill the vamps... AND avoid the authorities! The PCs may run into him, again!
Alternately, the PCs (or police) may come across a lifeless, bloodless body in a dust-and-clothes-filled alley, somewhere, and gain his equipment. Analyzing it might give some clues on new ways to stop the fang-gangs.
Or, the PCs might actually get to him before anyone else, either rescuing him while out on patrol, or being saved/aided by him... Can they convince the crotchety old coot that they're the good guys, and all can work together? (Beware, if Angel, Spike, or any other vampire is in the party!)

(Link added for the "final" encounter, if the PCs don't interfere! "Grampa" T. Rex Jones will be hauled off to jail at the end of this scenario, if the PCs do not intervene.)
