25 Brutal Serial Killer Families

Here is a truly scary list: 25 brutal serial killer families! When you think “serial killer,” it’s likely a sociopathic and anti-social loner comes to mind. But, that’s not always the case. Over the years, there’s been a number of brutal serial killer families, working together toward one nefarious goal.

There’s something even more terrifying about this fact. It’s one thing for a single psychopath to buy into their own insanity, but quite another for several others to buy into it, too. Yet, that’s exactly what happened. Whether it was a couple agreeing to do heinous acts against their fellow man or an entire family conspiring to torture, rape, and murder, these 25 brutal serial killer families were the lowest of the low. Fair warning, this list is not for the faint of heart.

Loren Herzog And Wesley Shermantine

Named “The Speed Freak Killers,” these two grew up as childhood friends in Linden, California, doing pretty much everything together. As adults, they developed a serious methamphetamine addiction, and may have started murdering people around 18 years old. From 1984 to 1999, they went on a meth-induced killing spree, murdering friends and strangers and anyone that got in their way. Sometimes they’d go on a hunt merely for the thrill of it. Once apprehended, their friendship disintegrated and they turned on each other. Shermantine was put on death row and Herzog ended up committing suicide. Authorities believe they killed at least 24 people, but Shermantine claims 72.


John Duffy And David Mulcahy

These two also became friends at a young age, bonding together after being heavily bullied in school. Soon, they became the bullies, terrorizing others for sport and committing burglaries and minor arson. As adults, in 1982, they led seemingly normal lives. However, at night, they would go out “hunting,” singing the song “Thriller” by Michael Jackson. At first, they preyed on women to threaten them with violence and rape them, but the violence increased with each attack, and eventually they committed several murders. They weren’t caught until 1999.


Kenneth Bianchi And Angelo Buono Jr.

Before being caught, these two men were known as “The Hillside Strangler” from 1976 to 1978 (originally, authorities thought the killer was only one man). In 30 days, they left the bodies of five women in the hills of L.A. and by the very end, they had murdered ten women and girls, ages 28 to 12. It started when Kenneth, Angelo’s cousin, came to live with Angelo. As the older cousin, Angelo acted as an authority to the wayward Kenneth, but Angelo was no role model. He convinced Kenneth to become pimps of teenage girls no one cared about. This idea led to their infamous murder spree. When the murders stopped in 1978, Bianchi left for Washington State and murdered two more women but was caught by police. He gave up his cousin, Angelo, during the interrogation. Buono died behind bars in 2002. Bianchi is still currently living out his sentence.

Part of a neo-Nazi group called “Ludwig” which carried out ritual murders, these two men became friends in Italy where they murdered at least ten people (though it’s likely fifteen). Their activities started in 1977, killing homosexuals, prostitutes, drug addicts and friars. They were arrested in 1984 for trying to burn down a disco club.

Also called “The Gang of Amazons,” this family from Stavropol, Russia, led by Inessa Tarverdiyeva and Roman Podkopaev, murdered 30 people in over six years. They brought their two daughters, one that was only thirteen years old, on their murderous raids. They were brutal, often doing horrendous things to their victims, like gouging out their eyes. Their killing spree lasted until 2013 when they were apprehended.
