Serial Killer Wives

We hear the shocking testimony of John, ex-boyfriend of pyschopath Joanna Dennehy. In 2013, she brutally stabbed three men to death and attempted to kill two more, becoming only the third woman in the country to be sentenced to life without parole.

John's friendship with Dennehy blossomed while he was walking his dog in the park. When it later turned into a relationship, he had no idea what the future would hold, and was delighted when their first daughter was born. However, Joanna's behaviour unraveled, until she was drinking heavily, using drugs and cheating on John.

She disappeared, leaving John to look after their daughter alone. Unbeknown to him, she had become violent and was spending time in and out of prison. When she did get in touch again, for the sake of his daughter, John took her back into the family home. They had another daughter, but Dennehy's behaviour deteriorated again, driving John to move away with their daughters for good.

Crime experts describe how Dennehy's world descended into sexual exploitation and violence. It came to a sickening end when she stabbed three men to death and hid the bodies in a wheelie bin before dumping them in the countryside.

John describes the unimaginable moment he received the text message that ripped his world apart – she had killed three men in cold blood and would go on to brutally stab two more men multiple times, leaving them for dead. He speaks of the shock he felt when he learned about the gruesome details of the murders, and how he wrestled with breaking the news to his beloved daughters. Now, he looks to the future and describes how he has worked hard to build a stable home life for his daughters.

This is the shocking true story of Terry, ex-girlfriend of serial killer James Randall. He was sentenced to death in 1997 for the brutal murders of two women and suspected of many more unsolved killings.

After falling into a downward spiralling lifestyle of drug abuse and sex work, Terry met Randall when he approached her as a new client on the streets. To help Terry find a new life, Randall offered her a relationship and a place to stay. Little did she know the terrible truth - that he'd been jailed for kidnapping, assaulting and abusing his ex-wife and was a suspect in the unsolved murder of her best friend.

As their relationship blossomed, Randall's behaviour became increasingly strange. He'd regularly hide in bushes and jump out at Terry, and at home strangle her until she begged him to stop. Afraid to confront him, Terry began to plot her escape from his increasingly threatening behaviour. Meanwhile, local sex workers were being found strangled to death.

One day, while in a college class, Terry was approached by detectives who revealed the shocking truth that turned her world upside down – her boyfriend James Randall was responsible for the murders of young women in the local area. They told her he was on the run and convinced her to help lure him back to her house where he was captured by a police dog unit.

Terry reveals the devastating and jaw-dropping moment Randall told her in prison that he'd killed the other women so as not to hurt her. Now, Terry has rebuilt her life and found happiness but will the nightmares ever stop?

This is the shocking true story of Martyn, ex-partner of notorious serial killer and necrophile Dennis Nilsen, who murdered at least twelve young men and boys in London between 1978 and 1983 before being sentenced to life in prison.

After running away from home aged 14, Martyn became a sex worker in London's West End. During this time, he met Nilsen in an arcade. They ended up at Nilsen's flat where Martyn fell asleep, only to wake in a room full of smoke, Nilsen looming over him with a knife. He pushed him off and left, confused by what had happened.

During the next few months, young men began to go missing from the West End. Martyn and Nilsen bumped into each other again and went back to Nilsen's flat, where they talked and bonded over their troubled upbringings. They began a casual relationship which would last for years.

Nilsen's behaviour became increasingly bizarre. He would shout at walls and ask Martyn sinister questions like whether he'd ever thought about bathing in blood. Martyn turned down Nilsen's invitation to move in with him.

One day, Martyn visited Nilsen at his new flat in Cranley Gardens, Muswell Hill, where he noticed a foul smell which Nilsen blamed on his dog. On another visit, he was denied entry by a clearly panicked Nilsen, who wouldn't let him through the front door.

Shortly after, Nilsen's neighbours complained about noxious odours coming from the drains. When a plumber investigated, he made a horrific discovery: human flesh and bones. The source was identified as Nilsen's flat and he was immediately arrested.

Martyn recalls the moment he saw reports on TV that his boyfriend had been arrested for murder, and how he struggled to cope with finding out the details of Nilsen's gruesome crimes, including storing bodies in his flat, having sexual encounters with his dead victims, dismembering them, boiling their flesh and flushing them down the toilet. Martyn also began to realise how close he came to becoming Nilsen's very first victim on the night they met.

Now, after decades of torment following his relationship with Nilsen, Martyn works as a counsellor for a mental health charity, using his traumatic experiences to help others.
