For Fred and Rose to abuse when they wanted to, over a period of days, almost devised belief.

Welcome to WatchMojo, and today we're looking at 10 criminal duos throughout the 20th century who earned infamy for their actions.

You struck Miss Lamp with a sledgehammer.

Do you recall the sledgehammer which was introduced?

Better known as the Toolbox Killers, Lawrence Bideker and Roy Norris murdered five girls in 1979.

They abducted their victims off the street, often posing as helpful strangers, before taking them to a remote area and killing them with various tools.

If you listen to the tape, you'll hear those pliers being replaced in a toolbox a few seconds later.

Douglas, the FBI agent who created the practice of criminal profiling, once called Lawrence Bideker the most disturbed man he has ever studied.

Indeed, the duo made a tape while killing Shirley Ledford, and the audio from this tape is used in FBI training to desensitize agents to the sound of murder.

They were both sentenced to prison, and both died within two months of each other.

Bideker in December 2019, and Norris in February 2020.

When his tape recording of one murder was played in court, people rushed outside and vomited.

The crime spree of Charles Starkweather and Carol Ann Fugate is a legendary piece of American history, influencing movies like Natural Born Killers, and being depicted in Terrence Malick's Badlands.

On January 21st, 1958, Starkweather killed Carol's mother, her stepfather, and her sister.

The pair then fled the house and embarked on a killing spree throughout Nebraska and Wyoming.

In just over a week, between January 21st and January 29th, 1958, the duo had murdered ten people.

They were finally caught following a car chase.

Fugate served 17 years in prison and was released in 1976.

Kit went to sleep in the courtroom while his confession was being read, and he was sentenced to die in the electric chair.

On a warm spring night, six months later, after donating his body to science, he did.

Ronnie and Reggie Kray were born in 1933 on the east end of London, and 30 years later, they were running an enormously successful criminal enterprise.

The brothers led The Firm, an organized crime gang involved in a wide range of illicit activities, like protection rackets, armed robbery, and murder.

They were brothers, but bound by more than blood.

Gangster princes of the city they meant to conquer.

Despite their criminal underworld dealings, the Krays attempted to present a respectable public image, running popular nightclubs and associating with celebrities like Frank Sinatra and Judy Garland.

However, their downfall came when Scotland Yard's Leonard Reed launched a determined campaign to bring them to justice, and he did so in the late 1960s.

Both brothers received life sentences and were incarcerated for the rest of their lives.

Reggie spent 33 years in prison for killing Jack McFitty.

Until the end, he carried a pair of tickets with him.

We were supposed to go to Ibiza after all.

The crimes committed by Moore's murderer Myra Hindley shocked the nation.

Hindley has been demonized as the most evil woman in Britain.

Called, quote, two sadistic killers of the utmost depravity by their trial judge, Myra Hindley and Ian Brady are responsible for the Moore's murders of the 1960s.

Between 1963 and 1965, Hindley and Brady abducted and murdered five young victims and buried their bodies on the Saddleworth Moor, hence the name.

Hindley often lured the victims, while Brady primarily directed the abuse and murder themselves.

She is actually reputed to have had a very normal childhood and then have met this very macabre stranger who then transformed her life into one of evil.

Their downfall came when Hindley's brother-in-law, David Smith, personally witnessed a murder and reported it to the police.

Despite promising that she was reformed, Hindley was never released from prison and she died in 2002.

Brady never repented or showed remorse for the murders and he died in 2017 after serving over 50 years.

You could call it a tragic love story, but I don't think you could put the word love in this.

Fred and Rosemary West I've never for one moment doubted that Frederick West was a truly evil man.

But he found in Rose the perfect sorcerer's apprentice.

Two of the most notorious serial killers in British history, Fred and Rosemary West owned an unassuming house in Gloucester.

But this place was later deemed the House of Horrors when people learned that it was harbouring the remains of their many victims.

The Wests would lure people to their house, murder them, and then bury their remains in the garden or the cellar. 25 Cromwell Street in Gloucester has become one of the most infamous addresses in Britain.

For 20 years, Fred and Rose West quenched their appetite for sex and murder inside this house of unimaginable horror.

And three of the victims were family members.

In 1971, Rose murdered Fred's stepdaughter Charmaine, supposedly resenting her presence in Fred's life.

Fred then murdered Charmaine's mother, Rena Costello, to cover their tracks.

And in 1987, both Fred and Rose murdered their own biological daughter, Heather, supposedly because she was growing suspicious of their secret criminal lives.

Fred had laid a patio behind Cromwell Street, it was in squares, which was rather like a crossword.

The family joke was that he buried Heather at two down and three across.

Paul Bernardo and Carla Homolka So I didn't suggest to him that we kill her on Sunday, but I knew that she, I knew that she had to be gone.

Sometimes called the Ken and Barbie killers owing to their attractive appearances, Paul Bernardo and Carla Homolka may have looked clean cut, but they were anything but.

Bernardo already had a history of sexual assault before meeting Homolka, but his crimes ramped up while working with his wife.

In 1990, they drugged Homolka's sister Tammy by lacing her drink and proceeded to sexually assault her.

Unfortunately, Tammy died after choking on her own vomit.

Her death was ruled an accident, and the evil couple were free to continue their crime spree.

Between 1991 and 1992, they kidnapped and murdered two more victims.

Bernardo was sentenced to life in prison, but Homolka only served 12 years after striking a controversial plea deal and testifying against her husband.

Her crimes were sickening to normal people, yet she escaped full accountability.

With breathtaking skill, she manipulated the justice system, took a 12-year sentence during which she got fit and educated, learned French, came out, got married, has three kids, lives, it seems, happily ever after.

On the night of August 20th, 1989, brothers Lyle and Eric Menendez murdered both of their parents with shotguns.

The scene was exceptionally gruesome, especially in the case of the mother, Kitty, who was shot repeatedly while she crawled on the floor.

The crime was initially blamed on intruders, but was eventually traced back to the brothers, resulting in one of the biggest trials of the century.

Prosecutors argued that the brothers were motivated by greed, hoping to inherit their parents' multi-million dollar estate.

The brothers claimed that it was self-defense, a killing motivated by revenge following a life of abuse.

While the first trial ended in a hung jury, the prosecution won the second, and the brothers were sentenced to life in prison.

Eric Harris and Dylan Klebold In the next seven minutes, Eric and Dylan will carry out the most brutal part of their assault on the school, the attack on the 56 students and staff hiding in the library.

Coming in at the very tail end of the 20th century was the Columbine Massacre.

In the early afternoon of April 20th, 1999, students Eric Harris and Dylan Klebold stormed the high school and began shooting, directly injuring 20 people and killing 13, 12 students and one teacher.

Three more were injured while fleeing the school.

Unfortunately, justice did not come to Harris and Klebold, as they took their own lives in the midst of the massacre.

They will make one last near suicidal gesture before ending their lives just a few meters from many of their victims.

The pain that the duo inflicted continues to linger, both psychologically and physically.

The 13th death, that of Anne Marie Hochhalter, occurred on February 16th, 2025, the result of sepsis complicated by her gunshot wounds.
