Throughout the early 1970s, California’s Bay Area was in the grip of terror as multiple serial killers operated at the time same time and in more or less the same space. In time, some of these killers, like Ed Kemper, would be caught, while others, like the Zodiac Killer, would remain unidentified. Yet it was the ones who appeared to kill at random, without any preferred victim, that would prove the most terrifying and most difficult to catch. Herbert Mullin was one such killer, and while he may have been active for a very short period, he managed to do a tremendous amount of damage in such a little amount of time.

Over a five-month period in late 1972 and early 1973, Herbert Mullin killed thirteen people, including a college girl, a Catholic priest, and a former high school friend and that friend’s neighbors. To investigators, Mullin’s victims appeared to be—and indeed largely were—chosen at random and the weapons used were chosen more out of convenience than pathology. Had Mullin’s final murder not been committed in full view of witnesses, there’s a very good chance he would have gone on to kill many more people before being caught, if he ever was.
