Being a serial killer seems like it could get lonely. With so much waiting and plotting and thinking, they're bound to crave some real human companionship, right? So why not find a lover with some similar interests and team up to become... a killer couple? Here is a list of serial killer couples from the past decades whose endless love ended others' lives.

Look at enough killer couples and you start to notice similarities - most killers were fleeing broken homes where violence, drinking, and sexual abuse were the norm. Most of the duos (but not all) found each other young and quickly began killing together. There's usually a dominant member of the couple, while the other was submissive and compliant, doing whatever they were told. In most cases though, both individuals had chances to flee but usually stayed.

The biggest, baddest, and most finite commonality between these couples is that they almost always turned on each other when they were caught, blaming the other one and saying they were the innocent one. Usually juries didn't buy it, and virtually all of these killers were either executed or are currently serving long prison terms. So brace yourself for some creepy stuff and read through this list of horrifying killer couples.
