On this weeks Murder With Friends, Grace is joined by Brett Erlich to discuss a series of unsolved murders from 1960's California infamously committed by a man known only as The Zodiac. They touch on every Zodiac kill that took place between 1968 and 1969, the Zodiac's relentless and notorious correspondence with law enforcement and the media, and some of the many suspects and theories that have surfaced over time.
