There are people who become absorbed in their fascination with notorious serial killers such as Ted Bundy. Some of these people become groupies who seek out and stalk the object of their obsession. Incredibly, there are groupies who even become the lover or spouse of an infamous predator.
For example, Richard Ramirez (the Night Stalker) married an obsessed journalist and groupie, Doreen Lioy, in 1996 while he was awaiting execution in California. Lioy vowed to commit suicide the day Ramirez was executed but he died of liver failure while still on death row in 2013.
