I'd recommend staying away from Internet dating sites, some look solid, others have the looks but upon meeting them you find out why their not relationship-builders. Serial killers choose their victims less discriminate and behave out of sexual fantasies or frustration, violent psychopathic delusions like Ted Bundy. Others like Dennis Rader(BTK) are disturbed sociopaths who develop specific killing patterns, they like playing God deciding who lives or dies. The most fascinating one, IMO, is the Zodiac Killer who terrorizes S.F in the late 50's/early 60's. Is ever one fit the "evil genius" psychopath, Zodiac's closer in the ballpark then Bundy, who earned a law degree from Washington.
