Homicidal maniacs walk among us, and they have to find some way to fund their compulsive murders. Here's a look at how some of the world's most notorious serial killers paid the bills while adding to their body counts.

This successful Indianapolis businessman founded the Sav-a-Lot thrift store chaine in 1988, and bought a mansion with a backyard that became a graveyard for the men he picked up in gay bars and strangled in his spacious home.

He thrived as an Amway salesman in St. Catharines, Ontario, Canada, but this handsome killer also used his people skills to kill a series of women. His wife would help by stealing drugs from the veterinarian's offices where she worked. He's serving life in prison.

There was plenty of room of Pickton's pig farm in British Columbia to hide the bodies of all the Canadian women he murdered, and some were actually fed to his livestock.

He's behind bars for life.

People could sleep securely knowing that Rader had installed their home security alarms. Meanwhile, he was terrorizing Wichita, Kansas. Between 1970 to 1990 as the notorious BTK killer. That stood for “Bind, Torture, Kill.” Rader's reign ended with his arrest in 2005 and he's serving 10 consecutive life sentences.

A lot of serial killers take up trucking, but Cox really took advantage of staying on the road all over the Pacific Northwest. Police suspect him in over 20 murders, but he's in prison in Oregon for the murder of two Portland prostitutes. He was convicted in 1993 and he was released from prison in February 2013, five years ahead of schedule.

This disgusting maniac defined a cliché while abducting and murdering at least 28 teens in Houston, Texas, between 1970 and 1973. His family owned the Corll Candy Company, and the psycho offered free samples to his victims, until he was murdered by an accomplice in 1973.
