Furnival Chambers barristers Nicola Shannon KC and Lisa Bald have successfully prosecuted TikTok influencer Winter Swan-Miller for the murder of 62-year-old Army veteran Stuart Crocker, following a complex 12-week trial at Winchester Crown Court.

Swan-Miller, aged 37, was convicted of murder after the court heard how she stabbed Mr Crocker 27 times at the Andover flat they shared in June 2023. She was subsequently sentenced to life imprisonment, with a minimum term of 23 years before the Parole Board can consider her release.

The case attracted significant media attention, not least because of the extensive social-media material generated by Swan-Miller both before and after the killing. Her own TikTok activity, alongside written notes, telephone evidence, forensic analysis and expert testimony, formed an important part of the prosecution case.

TikTok Material Became Key Evidence

Among the evidence presented to the court were videos posted by Swan-Miller following the murder. In one TikTok video, she referred to herself as having been a “bad girl” and encouraged viewers to contact her while she was in prison. Other material demonstrated that she continued producing videos after leaving Andover.

The prosecution also presented substantial quantities of draft TikTok videos recovered from her mobile telephone. These provided investigators with an extensive record of material created around the time of the offence and subsequently formed part of the evidential picture considered by the jury.

Swan-Miller also left a number of notes at the scene. The court heard that these included references to her belief that Mr Crocker was responsible for an earlier incident involving her Pomeranian dog, Oblivion.

Following the killing, Swan-Miller left Andover and travelled towards the Birmingham and Walsall area, where she stayed with an associate. Rather than disappearing from public view, she continued to make social-media content, take drugs and discuss the circumstances surrounding the killing.

Bank Card Use Helped Police Trace Defendant

The investigation took a further significant turn when Swan-Miller used Mr Crocker’s bank card. Police established that the card had been used on two occasions, including to withdraw his pension from an ATM in Walsall.

The use of the deceased’s bank card helped investigators trace Swan-Miller, who was eventually arrested outside a supermarket. Officers subsequently recovered further material, including a notebook, diary and sealed envelopes belonging to her.

The discovery of these materials added to the evidence concerning her actions and state of mind following the killing.

Meanwhile, Mr Crocker’s body remained undiscovered at his Andover home until neighbours reported a foul smell, prompting police to attend the property.

Forensic Evidence Challenged Self-Defence Account

The prosecution case involved more than Swan-Miller’s own social-media activity and written material. Pathological and blood-pattern evidence was presented to the jury to challenge her assertion that she had acted in self-defence.

The court also heard psychiatric evidence in relation to the partial defences of diminished responsibility and loss of control. Those arguments were successfully challenged by the prosecution, ultimately leaving the jury to consider the evidence supporting the charge of murder.

The case therefore required the prosecution team to address several complex strands of evidence, ranging from forensic pathology and blood-pattern analysis to digital communications, secret recordings and psychiatric evidence.

Swan-Miller had also made hours of secret recordings of conversations between herself and Mr Crocker. The prosecution case was that she had intended to use such material as purported evidence to support allegations against him.

Life Sentence Following High-Profile Trial

Following Swan-Miller’s conviction, HHJ Angela Morris, the Recorder of Winchester, imposed a life sentence with a minimum term of 23 years.

In sentencing, the judge described Swan-Miller as “a highly manipulative person who was prepared to do or say anything to get what she wanted”. The court also rejected suggestions that she had been sexually exploited, with the judge stating that any element of control or coercion had operated more strongly in the opposite direction.

The prosecution also highlighted the circumstances in which Mr Crocker’s body was left undiscovered while Swan-Miller continued with her activities after the killing.

Detective Superintendent Rod Kenny of Hampshire Police described the killing as having been carried out “in the most violent of ways”, while noting that Swan-Miller subsequently continued to post on social media and sought to justify her actions.

Nicola Shannon KC and Lisa Bald

Nicola Shannon KC and Lisa Bald were instructed by the Crown Prosecution Service Wessex following the investigation conducted by Hampshire Major Crime North.

The prosecution illustrates the increasingly sophisticated evidential challenges faced in serious criminal cases involving extensive digital material. Social-media posts, draft videos, mobile-phone downloads and private recordings can provide investigators and prosecutors with substantial evidence concerning events before and after an alleged offence.

For criminal barristers, such cases require the careful examination of large quantities of material alongside traditional forensic and witness evidence. The Swan-Miller prosecution demonstrates how these different forms of evidence can become interconnected within a complex murder trial.

Nicola Shannon KC was appointed King’s Counsel in 2023 and practises in serious and complex crime, fraud, regulatory offences and sports law, acting for both prosecution and defence. Her recent instructions have included homicide, organised crime, fraud, modern slavery and serious sexual offences.

She is also a Recorder in the Crown Court and has particular experience in intelligence-led investigations, international mutual assistance and cases involving vulnerable witnesses.

The successful prosecution of Swan-Miller represents another significant serious-crime case for Shannon KC and Lisa Bald, with the trial demonstrating the breadth of evidence that can now be central to a modern murder prosecution.
