Serial killer Joanna Dennehy warned her prison fiancée she was a ‘fully committed psychopath’

Serial killer Joanna Dennehy told her prison fiancée she was a ‘fully committed psychopath’ in a harrowing love letter. 

Dennehy, 39, who was jailed in 2014 after killing three men during a 10-day spree, was engaged street robber Hayley Palmer while they were both behind bars.

The pair both were incarcerated at the privately-run HMP Bronzefield in Middlesex, but they split after being moved to separate prisons. 

Palmer, who is now a free woman after serving 16 years, has opened up about their romance with the killer, revealing Dennehy had ‘no regrets’ and would ‘laugh’ about her crimes. 

In a letter seen by the The Sun on Sunday, Dennehy wrote: ‘You have a fully committed psychopath.

‘Together we will travel a path so beautifully dark, so mentally and physically dangerous we will cease to know where I begin and you end.’

Mother-of-two Dennehy is one of only two women in Britain serving a whole-life prison term – the other is Rose West. 

She stabbed three men to death whose bodies she dumped in ditches outside Peterborough, where she lived before knifing two more men in Hereford.

Dennehy’s first victim was a Polish man, Lukasz Slaboszewski, 31, who had come to believe Dennehy was his girlfriend.

She lured him to a property with suggestive texts, then stabbed him through the heart.

Dennehy then used a pocket knife to kill her housemate John Chapman, 56, stabbing him once in the neck.

The third victim was her landlord, Kevin Lee, 48, who she lured with the promise of sexual favours.

Excited by the police manhunt for her, she then stabbed Robin Bereza from behind in Hereford on April 2, 2013. Nine minutes later, she knifed John Rogers. 

Both men survived and Dennehy was caught after two days on the run.   

‘She laughed at the situation and had no regrets at all’, said Palmer. 

Palmer met the killer at HMP Bronzefield but were later moved to separate prisons, with Palmer going to HMP East Sutton Park in Kent while Dennehy now resides in HMP Low Newton in Durham. 

In May 2021, friends told the Mirror Palmer was seeking legal advice on arranging the wedding to Dennehy despite her life tariff for murdering three men. 

‘It’s a very strange relationship. It’s very weird to say but they seem good for each other’, said the friend. 

‘Hayley speaks about Joanna like she’s her high school sweetheart. They talk every single day and fully intend to get married.

‘Hayley joked that they would not be allowed to cut their wedding cake because there’s no way that they’d let Joanna have a knife.’

The couple reportedly wanted to be married by the end of the year – however Dennehy is said to have broken off contact with Palmer two months ago. 

Dennehy, who was brought up in a stable family home in the Home Counties, carried out her horrific attacks to gratify her ‘sadistic love for blood’.

The Old Bailey was told the killer had a ‘sexual and sadistic motivation’.

Later she told a psychiatrist: ‘I killed to see how I would feel, to see if I was as cold as I thought I was. Then it got more -ish.’

Experts said Dennehy craved notoriety and wanted to humiliate her victims through sick sex games. Before the killings she had boasted she had already killed four times.

When the three bodies were found, police launched a high-profile murder investigation.

Meanwhile Dennehy travelled to Hereford and started scouring the streets with accomplice Gary Stretch for more men to kill.

She told him: ‘I want to have my fun.’

The pair randomly selected two dog walkers, retired fireman Robin Bereza, 64, and John Rogers, 56.

Dennehy stabbed them in frenzied knife attacks. Both survived the horrific attacks only because of swift medical intervention.

During her search for further victims, Dennehy posed for photos with a huge serrated knife and bragged that she and Stretch were ‘like Bonnie and Clyde’, whose gang killed nine policemen in 1930s America.

The victims of Joanna Dennehy’s three-day murder spree

LUKASZ SLABOSZEWSKI

The 31-year-old moved to the UK from Nowa Sol, Poland, in 2005 to work in a DHL warehouse in Peterborough.

Cambridge Crown Court heard that, at the time of his death, he was being prescribed methadone as a substitute for his heroin addiction.

He was last seen alive leaving his home in the city’s Lincoln Road on March 19 last year having met Joanna Dennehy for the first time the previous day. He told friends he had found an ‘English girlfriend’.

It is thought he was stabbed to death in a property in Rolleston Garth on or soon after this date.

Afterwards, Dennehy stored his body in a wheelie bin for several days before dumping it in a ditch at Thorney Dyke along with that of John Chapman. Their bodies were discovered by a farmer on April 3.

In a statement issued after his death by Mr Slaboszewski’s sister, Magda Skrzypczak, said: ‘Lukasz was the joker in the family, always finding something to laugh about. His mum and dad are devastated by their loss and he also leaves two grieving sisters.’ 

JOHN CHAPMAN

The 56-year-old, originally from Leeds, had served with the Navy in the Falkland’s war.

Jurors heard he had fallen on hard times. He was an alcoholic but known as a ‘friendly drunk’, the court heard. Mr Chapman lived in the same set of bedsits as Dennehy in Bifield, Orton Goldhay.

He described Dennehy, who had been employed as an ‘enforcer’ by landlord Kevin Lee, as the ‘man woman’ and friends were concerned for his safety as she attempted to force him to move out, the court heard.

He was killed in his bedsit on March 29 after Dennehy stabbed him in the heart. A photograph of his body, timed at 7.32am that day, was found on Leslie Layton’s phone.

Mr Chapman’s body was found alongside that of Mr Slaboszewski on April 3. At the time, his family released a statement saying: ‘We are all so upset and shocked by the tragic loss of John.

‘He was a loving brother, brother in law and uncle. He was much loved by all who knew him and will be missed by all his friends and family.’

Property developer Kevin Lee, 48, who was found dead in Peterborough.

KEVIN LEE

The 48-year-old lived in Fletton, Peterborough, with his wife Christina and their two children.

He ran the Quick Let property firm, which specialised in providing bedsits to people of ‘limited resources’, prosecutors said.

Business partner Paul Creed told the court Dennehy had approached them seeking accommodation. Mr Creed had been reluctant to house her but Mr Lee wanted to ‘give her a chance’.

Mr Lee later employed Dennehy as a decorator and enforcer, the court heard. On March 20, Mr Lee confessed to his wife that he was having an affair with Dennehy.

Nine days later, on Good Friday, he gave Dennehy an Easter card. Later that day she called him on the phone and arranged to meet him at Rolleston Garth – where Mr Slaboszewski had been killed – before stabbing him to death.

Mr Lee’s body was found by a dog walker in a ditch beside Middle Road, Newborough, on March 30. His family issued a statement saying: ‘We are devastated by Kevin’s death, he was a wonderful husband, father, loving brother and son.

‘His naturally infectious personality touched everyone who knew him. He will be hugely missed by all his friends and family.’
