Life Sentence for Boyfriend Who Murdered Partner After 10-Day Captivity
A violent boyfriend who murdered his partner after holding her prisoner for ten days has been sentenced to life imprisonment, with newly released police footage capturing his distraught reaction upon arrest. Tony Devenport, 57, received a life sentence at Chester Crown Court for the killing of 41-year-old Stephanie Blundell, who was discovered with extensive bruising across her face and body.
Gruesome Discovery and Sustained Assaults
Ms Blundell was found dead lying on a mattress by her father, Philip Blundell, last July at the home she shared with Devenport on Canal Street in Chester. The court heard that Devenport left his victim to die with more than 100 injuries after feeding her vodka and ice lollies while she was trapped in his house. He has been ordered to serve a minimum term of 22 years behind bars.
Jurors found him guilty of murder following a trial that concluded on Wednesday. After sentencing, police condemned his lack of remorse, while Ms Blundell's family paid tribute to her as 'one of the most radiant souls you could ever hope to meet'.
Arrest Footage Reveals Distraught Defendant
Cheshire Police have now released footage of the moment officers arrived to arrest Devenport, in which he is heard whimpering and asking whether Ms Blundell was dead. An officer is heard asking, 'Why have you got blood all over you?', before Devenport replies: 'Why have I got blood all over me? Where?'
As police urge him to 'calm down', Devenport begs, 'Please help me - please help me', while also insisting, 'I've not done nothing to her', and asking: 'Is she alive?' When placed in the back of a police car in handcuffs and informed he had been arrested for murder, Devenport says: 'So that means she's dead?' He added again: 'I've not done anything.'
Judge's Sentencing Remarks and Family Impact
Passing sentence on Devenport on Friday, Mrs Justice Steyn told the defendant he had murdered his 'compassionate, kind-hearted and courageous' partner of two years. The judge stated: 'Stephanie Blundell died on the morning of July 20 2025 as a result of fierce, repeated and sustained assaults inflicted by you over the preceding day or two.'
She continued: 'Her father had the most terrible experience a parent can face of visiting her shortly after midday on that Sunday, only to discover that his beloved daughter lay dead, with the marks of the severe beatings you had meted out abundantly clear.' The judge added that Ms Blundell always saw the good in people, including Devenport, and had an enormous capacity to love.
In an impact statement, Ms Blundell's father told the court that discovering his daughter will 'stay with me for the rest of my life'. He said: 'The thought that she died alone in pain with nobody to comfort her haunts me every day.'
Controlling Relationship and Alcohol Abuse
The court heard that when Devenport met Ms Blundell, she had been suffering with an alcohol addiction for years, but the couple had been in a period of sobriety until they took a trip to Slovakia in May last year when they started to drink 'heavily'. Devenport was controlling and coercive towards Ms Blundell; although they had lived together for nearly two years, she did not have a key to their house, and he kept her bank card in his wallet.
'When intoxicated, you were abusive, aggressive and violent towards her on occasions prior to her death', the judge said. Devenport was arrested on suspicion of assaulting Ms Blundell 10 days before she died but breached his bail conditions 'within minutes' by calling her phone. She 'never left' his house again after he called a taxi to pick her up.
Final Days of Captivity and Fatal Injuries
Between July 10 and 20, Ms Blundell had 'no means of contacting anyone' and was bed-bound, while Devenport bought more than 12 litres of vodka and 72 cans of beer. The judge said that evidence showed Devenport strangled Ms Blundell twice in the day or two before her death and beat her, causing significant injuries to her brain.
Mrs Justice Steyn stated that Ms Blundell, who had acute pancreatitis and alcoholic ketoacidosis, was 'bound to be pleading with you for help' in the days before her death, but he only gave her alcohol and ice lollies. She told the defendant: 'As a result of your actions, Stephanie would have been in pain and fear and you kept her there, offering little but vodka.'
A post-mortem examination found she died from multiple injuries inflicted upon her, exacerbated by the effects of chronic alcoholism. In a statement released after sentencing, Ms Blundell's family said: 'Steph was, without question, one of the most radiant souls you could ever hope to meet. She was kind-hearted, quick-witted and effortlessly stylish.'
Police Response and Campaign of Terror
Detective Inspector Andrea Price, from Cheshire Constabulary's Major Investigation Team, said: 'Stephanie was loved and cherished amongst family and friends, and although today marks the day her killer is brought to justice, I want Stephanie to be the one who we remember.' She added that while no sentence can ever bring Stephanie back, she hopes the result provides her loved ones with some comfort.
Devenport had waged a campaign of terror against Ms Blundell, which she likened to the horror movie The Shining. The killing came just days after she told police: 'He's going to murder me.' She also told friends she was living in fear of his paranoid rages, comparing them in messages to those featured in the 1980 film starring Jack Nicholson.
Defendant's Claims and Victim's Background
A remorseless Devenport told police he had 'just slapped her about a few times the night before' and insisted she had fatally hurt herself while drunk. However, she had multiple bruises on her face and body and weighed just 48kg when found by her father. In harrowing testimony, Mr Blundell told Chester Crown Court she looked 'like a zombie' when he discovered her at the apartment.
In the weeks before her murder, Ms Blundell, who once worked in Paris as a globe-trotting executive for luxury watchmaker Tag Heuer, had been on an 11-day holiday with Devenport to Kostice, Slovakia. She posted social media pictures of the couple with the caption: 'A genuine moment caught between all the staged pics.' But the pair clashed over his heavy drinking during the trip, and following their return, he kept her confined to their home in Chester.
Father's Discovery and Defendant's History
Mr Blundell made the nightmarish discovery on June 20, 2025, when he went to the couple's apartment to find Devenport wandering around in 'an intoxicated daze'. In a statement to police, the father said: 'I hammered on the door and Tony came to the door quite quickly. He was in a right state, physically and mentally and he said: "I think she's dead, I think she's dead".'
He added: 'I said, "What do you mean, you think she's dead?", but he [was] weeping and emotional and just psychotic. He said: "she's in there" and I go into the back bedroom, and it's, it's just a terrible, terrible sight. I knew straight away she was dead.'
Devenport told police that the only violence he inflicted on Ms Blundell was when he grabbed her arms hard the previous evening and pushed her onto a mattress. He claimed the victim must have suffered an internal injury caused by her own abuse of alcohol and died unexpectedly, seconds before her father arrived. The court heard he had told his brother he had been planning to ask Stephanie to marry him and added: 'I just slapped her about a few times the night before.'
Victim's Career and Relationship Deterioration
The court heard that Stephanie was a 'talented young woman' who, after leaving university, got a job as an intern in 2007 with watchmaker Tag Heuer. She impressed bosses with her work and, after a series of promotions, would attend Formula One social events and arrange backstage access to celebrity guests.
During her ten-year career, Ms Blundell rubbed shoulders with motor racing stars Lewis Hamilton, Stirling Moss, and Damon Hill, as well as artists Pharrell Williams and Kanye West. She would travel to Los Angeles, San Francisco, and New York, but her life began to deteriorate when she herself began drinking heavily, moved back in with her parents, and met Devenport in 2024.
Defendant's Background and Final Incidents
Devenport had previously been involved with his brother in a go-karting business in Deeside, on the England-Wales border, before going on to buy and renovate properties in Chester. But he began abusing alcohol himself following issues over a business deal. Prosecutor Owen Edwards said: 'When sober, he was described in messages from Stephanie as a kind man. But when in the middle of a binge his behaviour scared Stephanie.'
Devenport entered rehab at a Priory clinic and eventually quit drinking but fell off the wagon last May during the couple's trip to Slovakia when he was told his mother would have to move into a nursing home due to dementia. Mr Edwards added: 'Once again his behaviour became a source of real concern to Stephanie who messaged family members about his behaviour.'
On their return from Slovakia, they got a taxi home, but the driver called the police because she had complained: 'He'll batter me when we go in - if I go in there now, he'll just punch me.' The court heard police did attend the property following the cab driver's call and arrested Devenport for assault, but Ms Blundell asked that no action be taken against him.
She told officers: 'He's like full on serious like gunna murder me... but I mither him and I shouldn't do that. I am so sorry.' In the days before her death, the couple booked into the Pied Bull hotel, a former coach house in Chester, for two nights in a bid to save their relationship. But staff were called to an argument, and Devenport was thrown out in the early hours.
