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 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 are either on death row or serving long prison terms. So brace yourself for some creepy stuff and read through this list of horrifying killer couples.

Suzan and James Carson became famous as the San Francisco Witch Killers for their murders of at least three, and maybe as many as a dozen people who they claimed had “evil energy.” Describing themselves as "vegetarian Muslim warriors”, the duo took massive amounts of drugs, converted to Islam and lived on a pot farm. Then they started killing.

The first was in Haight-Ashbury in 1981, when they beat their roommate with a frying pan, then stabbed her a dozen times. They killed at least two more people, attempting to rid the world of witchcraft. They had a list of others to kill, some people who were acquaintances, and others in the celebrity world. They were eventually caught, and held a press conference admitting to the murders, which they claimed were done to break evil spells that had been cast on them. Both were given prison terms of 75 years to life.

Fred and Rosemary West were a model couple for other horrible people to emulate. Fred claimed his childhood home was full of incest and his dad taught him bestiality. In 1971, Fred went to prison for theft, and Rosemary murdered Fred’s stepdaughter because the girl wouldn’t cry during the beatings she gave her. Once Fred got out, he encouraged Rosemary to become a prostitute, and then began raping their daughters.

Over the next six years, they killed 9 women, then two more in the next two decades. Finally, in 1995, Rosemary was convicted on 10 counts of murder and sentenced to life. Fred killed himself while in custody pending his trial. The two briefly popped back into the public eye after Donald Trump unwittingly retweeted a photo of the couple.

Sisters Delfina and Maria Gonzales cut a swath of destruction unmatched in the history of horrible murder. Together, the Mexico City sisters are responsible for at least 91 murders (and possibly as many as 110) in the 1950’s and 60’s. They were so good at it that their mass murdering had gone unnoticed until a young woman accused of an unrelated kidnapping told Mexican police about their brothel compound north of the Mexican capitol. The sisters’ property was searched, and there were found the remains of 11 men, 80 women, and several fetuses.

It came out that Maria and Delfina had a system of recruiting prostitutes under the disguise of hiring maids for a cleaning service. Then the girls were drugged, pimped, and once they lost their looks or became useless as sex workers, the sisters killed them and dumped the corpses in a pit. The pair were eventually sentenced to 40 years in prison. Delfina died in prison, but amazingly, Maria did her time, got out of prison and vanished.

Starting in 1984 and working together, killer couple Alton Coleman and Debra Brown committed an astonishing roll call of eight murders, seven rapes, three kidnappings, and 14 armed robberies over the course of two years. Their relationship was likened to a master and slave, with Coleman a vicious killer and Brown his willing helper. In a particularly sickening twist, the couple, both African-American, targeted other black people, befriending them, then attacking when their guard was down.

Both were eventually found guilty and sentenced to die. Brown’s term was reduced to life in prison, but Coleman was executed in 2002.
