In short:

The VCTF Team = The CBI Team

Jack murders Samantha's husband.
Samantha joins the VCTF as a consultant and together they hunt down Jack for a couple of seasons.
At some point they catch a fake Jack.
They hunt for him some more. They compile a list of possible suspects.
They discover Jack's real identity is Ed Post, the sheriff of a small town nearby.
They try to catch him with an elaborate ruse and ultimately Samantha shoots and kills him in the cemetery where her husband is buried.
