Before there were shows like CSI, there was Profiler.  Profiler was one of the first shows to deal with profiling and forensics.  The show boasted a memorable cast of characters, lead by Ally Walker in the role of Dr. Samantha Waters throughout the first three seasons and later in the fourth season by Jamie Lunar as profiler Rachel Burke.  The driving plot of the first three seasons was serial killer, Jack Of All Trades relentless stalking of Dr. Waters.  One unique fact about the cast is that actor Dennis Christopher, wasn't given screen credit for Jack until the very end.  Additional cast members included the distinguished Robert Davi and actor Peter Frechette, as well as Roma Maffia and Julian McMahon who star in FX's Nip/Tuck.  Other memorable actors who appeared regularly during the show's four seasons includes: A. Martinez, Erica Gimpel, Michael Whaley, Caitlin Wachs, Heather McComb, Sheik Mahmud-Bey  and Traci Lords.
