The daughter of serial killer Joanna Dennehy has revealed how her loving mother turned into a man-hating serial killer.
Shianne Treanor said Dennehy ‘deserved to die in prison’ and has apologised to her mother’s victims for her horrendous crimes.
The 19-year-old was raised by her father John Treanor who moved Shianne away from Dennehy when she started to act violent.

After visiting her mother in prison for the first time, Shianne spoke of the emotional roller coaster she had been on, growing up in the shadow of a killer.
Speaking to the
‘She deserves to spend the rest of her life in prison.
‘I’m sorry to the victims. I can’t imagine what they went through.’

In 2013 Dennehy stabbed three men, torturing one and then dumping the bodies. Shianne had been attending a sleepover at a friend’s house when her father called her to tell her mother had killed someone.
When Shianne turned 18 she decided it was time she learnt about her mother and last October, penned her a letter.
‘I was really cold because I thought she hated me. I told her I wasn’t looking for a relationship with her, I just wanted to know why.
‘But I got a letter full of love and warmth and how much she wanted to have me in her life. I just cried. It was so emotional.’

She said she had been nervous ahead of the meeting at HMP Bronzefield in Surrey and highlighted that she had been ‘shaking’ as she entered the prison.
‘When I got into the visit hall I had to take a double look when I saw her. She looks completely different.
Dennehy still ‘drawing men in from her cell’
Joanna Dennehy is still ‘drawing men in’ with chilling letters penned from inside her prison cell, it has been revealed.
The murderer, who killed three men during a 10-day spree, continues to manipulate male admirers and even had one propose to her, according to a new documentary.
The new ITV show hosted by Susanna Reid will investigate how the killer continues to crave attention from her cell at HMP Bronzefield in Surrey.
In one shocking scene from the programme, viewers are shown Dennehy laughing and flirting with officers in a police station minutes after her arrest.
Standing at the custody desk while playing with her hair, she boasts: ‘Attempted murder and murder is nothing. It’s like going down for a Sunday roast… easy.’
A shocked Susanna Reid states: ‘Those tapes from the custody suite are mindblowing.
‘You’d expect a wave of realisation coming over her that she is now going to face justice for this horrific brutality. Not at all. Not a moment of it.
‘She doesn’t show any remorse, she’s revelling in what she’s done. It’s appalling behaviour but a sign of the psychopath that she is.’
‘We were the only people in the room apart from the guards. We sat opposite each other at a table.
‘She was wearing a black T-shirt, blue jeans and boots. She’s got short blonde hair and piercings on her face, one next to her eye. She looks well.
‘I said to my mother, ‘I’ve missed you.’
Shianne said she never believed she would see her mother again or that she would be in her life.
‘We both just cried. I asked her, ‘Why?’
‘She apologised to me. It doesn’t make it right and doesn’t excuse anything but I wanted the apology.
‘Part of the punishment is that she will never get to see me grow up or get married.’
Shianne, however, still holds fond memories of the person her mother was, before drugs and drink took over.
She said Dennehy loved to read and that she spent a lot of her time curled up on the sofa with a good book, or out on long walks.
‘She loved Mr Darcy. She read Pride and Prejudice. She would talk to me about it all the time.
‘She’d do paper-mache art with me and my friends.
‘We had a hallway just inside the front door and one day my mum and my friend we got paint and painted all the walls with drawings.
‘My dad got home and he was really, really mad but to me that was a really happy memory.
‘I had another friend and in the summer Mum would get the paddling pool out and we’d do somersaults into it and make mud pies. She was just a really big kid.’
Shianne was born in 1999 in Milton Keynes, when Dennehy was just 17-year-old.

Shianne’s father John, now aged 42, left Dennehy over claims she had been unfaithful and when the living situation became unbearable, he moved his daughter to Norfolk.
The pair rekindled their relationship and moved to Wisbech where Dennehy worked on a farm.
Three years later they had a second child.
John, who works as a security guard has since expressed how Dennehy turned into a ‘devil’, drinking strong lager at breakfast, cutting herself and downing bottles of vodka.
Shianne added: ‘She had gone out drinking. In the middle of the night she sent a man round to beat up my dad. It was terrifying.
‘I was about five and I had woken up and I heard this shouting. There was this man outside shouting at my dad.
‘He said, ‘Jo has sent me here because you’ve done this,’ but I didn’t know what. My dad shouted at me to go back to bed so I did. I didn’t know what happened after that but I was petrified.
‘My mum would just come home after being away for so long and she would have a black eye from a fight.’
Dennehy would disappear for days on end, sometimes for months.
Shianne said: ‘She would come home and she would have cuts all over her or she’d been cheating and she’d have love bites and she’d have to hide it with a scarf.
‘They would have massive arguments. I don’t know what about but they’d be screaming at each other for hours and hours and hours.’
John finally took the plunge and left after Dennehy stabbed a six-inch knife into the carpet.
John took Shianne, nine-years-old at the time, and moved the Derbyshire.
In 2013 Dennehy pleaded guilty to three murders and two attempted murders.
Two men were convicted alongside her after the killings in Peterborough. Dennehy is one of only three women to be given a whole life jail term, the others being Rose west and Moors murderer Myra Hindley.

Dennehy is now 36-years-old and admitted to killing for fun.
She said: ‘It got moreish. I got a taste for it.’
Speaking to a psychiatrist she said she had been ‘sorry’ for the attempted murders, but not sorry for the muders.
Shianne’s father had previously banned her from using the internet, in order to prevent finding out about her mother.
However, at the age of 13 she accessed the internet and learnt all about her mother. Soon after she because depressed and as more and more people found out who she was, she had to move school.
She was frightened she would turn out like her mother and asked her father if that was a possibility.
She added: ‘It was a genuine thought. I was only 13 and I didn’t know if it was a genetic thing.’
Now living in Manchester, Shianne has completed a travel and tourism course at Tameside college and added that she would ‘never turn out’ like her mother.
‘I’m my own person. I might have some personality traits of hers but we’re two different people.
‘I was not around her for many years. She hasn’t had that massive influence on me.’
Shianne added: ‘I can’t believe she did what she did. It makes me want to cry.
‘She’s hurt those people and I can’t ever forgive her for that. She should spend the rest of her life in jail thinking about the misery she’s caused.
‘In a way she’s completely ruined my life. I have this family name associated with the fact she’s taken lives.
‘When Myra Hindley was arrested they never found where the bodies were because she never gave anything up.
‘In a way, because my mum hasn’t said anything, or given an explanation, those families will never understand.
‘I can’t get my head around it. I think she should explain why she did what she did. Those families deserve peace of mind in their lives.
‘They are in the dark. Like me, they should have a reason why. ‘
The victims of Joanna Dennehy’s three-day murder spree
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.’
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.
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.’
