Serial killer Joanna Dennehy told her prison fiancée she was a ‘fully committed psychopath’ in a harrowing love letter.
Dennehy (39), was sentenced to 10 days in prison for the murders of three men over a 10-day period. Hayley Palmer was Dennehy’s street robber while they were behind bars.
They were both held in HMP Bronzefield (privately-run) in Middlesex. After being released, the pair split and 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.
Dennehy, in a Sunday Sun letter, wrote that he was a completely committed psychopath.

Joanna Dennehy (37) was jailed in 2014 for her 10 day killing spree.

Dennehy was reportedly engaged street robber Hayley Palmer (pictured), who has been released after serving 16 years
“Together, we will follow a path that is so dark and so dangerous mentally and physically we will never know where we begin or end.”
Mother-of-2 Dennehy is the only woman in Britain currently serving a full-life sentence. Rose West is the other.
Three men were killed by her stabbing attack. The bodies of the victims she left behind in ditches near Peterborough. She then moved to Hereford and knifed two additional men.
Dennehy first victim was Lukasz Slaboszewski (31), a Polishman who believed Dennehy to be his girlfriend.
With suggestive words, she lured him into a house and then attacked his heart.
Dennehy, then 56, used a pocket knife and stabbed John Chapman once in the neck.

Dennehy was a serial killer and is serving a whole life sentence. She’s one of just two women currently in that position.
Kevin Lee, her 48-year-old landlord was her third victim. She lured him with promises of sexual favors.
In her excitement at the prospect of being arrested for her, Robin Bereza stabbed Robin Bereza. This happened in Hereford on April 2, 2013. John Rogers was also stabbed by her nine-minutes later.
Both men survived and Dennehy was caught after two days on the run.
Palmer said that she laughed about the situation, and didn’t regret anything.
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 an odd relationship. The friend said that although it was strange to admit, they seemed good for one another.
“Hayley talks about Joanna as if she were her high school sweetheart. They speak every day, and both are fully committed to getting married.
Hayley joked that the couple wouldn’t allow Joanna to cut the cake at their wedding because they don’t have any other way.
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 was raised in a safe family home in the Home Counties and carried out her horrible attacks in order to satisfy her’sadistic passion for blood’.
An Old Bailey witness said that the killer was motivated by’sexuality and sadness’.
She later told a psychiatrist that she had killed herself to feel the cold, and to find out if it was true. It got worse.

Dennehy (pictured), told psychiatrists that she had killed herself ‘to feel how it would make her feel’, and it was more-ish.

Low Newton prison, Durham. Joanna Dennehy currently serves her sentence in this low Newton prison.
Experts say Dennehy wanted notoriety, and she was desperate to make her victims feel humiliated through sex. Dennehy boasted to having killed four people before she committed the crimes.
Police launched an investigation into the murder of three people after they were discovered.
Dennehy and Gary Stretch then set out to find more murderers as they scoured the streets of Hereford.
She said to him, “I want to have fun.”
Randomly, Robin Bereza (64), and John Rogers (56) were chosen by the pair as dog walkers.
Dennehy attacked them with a frenzied knife attack and stabbed them. They were both saved by quick medical attention.
Dennehy took photographs with a big serrated knife while searching for other victims. Stretch praised Dennehy for being ‘like Bonnie & Clyde’ who killed nine policemen in America in the 1930s.
