PLOT: Kolchak investigates the murders of targeted mobsters in the Chicago numbers racket, which leads to a revenge-driven African American woman who uses voodoo to resurrect a carcass as a personal killing machine. When Carl interferes, she doesn't hesitate to put him on the hit list.
COMMENTARY: This episode introduces coroner Gordy the Ghoul (John Fiedler) and Monique Marmelstein (Carol Ann Susi), Carl's co-worker at INS, both of whom appear in three episodes each. The latter went on to appear in a couple episodes of Seinfeld and 40 episodes of The Big Bang Theory as Howard's mother, albeit just her annoying voice.
The two memorable components of this episode are (1.) Monique trying (but failing) to be Kolchak's partner on the street and, more importantly, (2.) the formidable zombie, which is surprisingly creepy in the last act at a junkyard.
There's a seeming plot hole about how the zombie can escape its grave without any evidence of doing so beyond an empty coffin. Are we to assume that voodoo enabled the corpse to teleport from its coffin six feet under to the ground above? A simple explanation is that the Voodoo woman had the corpse dug up by someone and then had the hole refilled after the body was removed.
