I am late to the party. My great great grandfather murdered his first wife and eldest son. He smothered my great great grandmother because she caught him cheating on her, and he had his business associates throw what would have been my great great uncle down a mine shaft and left him there until he died because he was became involved in dealing drugs. It was the turn of the century in industrializing America. He paid off the police chief both times. The official record says that my great grandmother died of a heart attack, and my great uncle's death was ruled accidental.

These were not the only instances of his disposing of people who were inconvenient to him. He murdered a business associate who shorted him two hundred thousand dollars in a commercial contract, by pushing him off the edge of a mountain while the two were hunting. Again, the death was ruled accidental. The contract was for the transportation of coal by rail.

My great grandfather, the third from the oldest son, not to be outdone, also murdered his first wife in the same way -- although for a different reason. They simply did not get along, and he smothered her to death in her sleep. As a teenager he was accused of murdering three men who were involved in a robbery of one of his friend's parents, although charges were never filed. He also "accidentally" ran over another man who happened to be bidding on a piece of property that my great uncle was bidding on as well with his car and killed him. No charges were filed.

They were both "associated" with about a dozen other mysterious deaths, between them. Rumor had it that when some mob types tried to shake them down for the proceeds of a contract that involved a few companies in the North East, they threw the guys off a building into a brick parking lot and that, when enforcers showed up to figure out what happened, they mysteriously disappeared too.

This stuff was all from the turn of the 20th Century until about the 1950s, though. Ancient history, now.
