Last Night was the series finale of CSI Vegas but from a recent article on TVLine there was a teaser for a potential season 4 that got edited out because of the show being cancelled 

and what was edited out was a teaser only shown in press screeners teased a new killer who preys on the unhoused with a hand scythe/sickle which we will now not get to see unless everyone keeps signing and sharing this petition and maybe get the attention of another network to pick CSI Vegas up
