NEW FORENSIC EVIDENCE RECONSTRUCTS PRESTON DAVEY’S FINAL WEEKS — AND THE TIMELINE THAT DESTROYED THE ACCIDENT THEORY

A 13-month-old boy suffered more than 40 injuries during the final months of his life, according to prosecutors. Now, medical and digital evidence has helped investigators reconstruct a disturbing timeline that ultimately contradicted Jamie Varley’s explanation for what happened to Preston.

BLACKPOOL, England — The case of Preston Davey was never simply about what happened on the afternoon the toddler was rushed to hospital.

According to evidence presented at trial, the story stretched back weeks — through photographs, videos, medical records and messages that prosecutors said documented repeated physical and sexual abuse of a child who was supposed to be entering a safe, permanent home.

Preston was only nine months old when he was placed with Jamie Varley and John McGowan-Fazakerley with a view to adoption.

Four months later, he was dead.

Varley was subsequently convicted of murder and multiple other offenses. McGowan-Fazakerley was convicted of allowing the death of a child, child cruelty and sexual offenses.

THE NUMBER THAT TOLD PART OF THE STORY: 40

The post-mortem examination found that Preston had suffered around 40 injuries.

Those injuries included bruising to his mouth, throat, bowel and bladder, as well as a healing fracture to his left arm that experts determined was non-accidental.

But the number alone does not explain the case.

What made the evidence so significant was that medical experts concluded injuries had occurred at different points during Preston’s time with the defendants.

The prosecution therefore presented the injuries as evidence of repeated harm rather than one isolated incident.

The Crown Prosecution Service said the evidence showed Preston had been “routinely ill-treated” during the final months of his life.

THE PHONE RECORDS BECAME A DIGITAL TIMELINE

Investigators also examined evidence stored on the defendants’ phones.

Photographs and videos became crucial because they could establish what Preston looked like at particular moments and provide investigators with dates against which medical evidence could be compared.

The prosecution said phone evidence showed instances of child cruelty and also established that Varley had taken indecent images and videos of Preston.

That digital trail allowed investigators to build a chronology of Preston’s final months.

Instead of looking only at the circumstances surrounding his death, investigators could examine what had happened to him beforehand.

THE FRACTURED ARM WAS ANOTHER WARNING SIGN

Among the injuries was a healing fracture to Preston’s left arm.

Experts concluded that the fracture was non-accidental, according to the CPS.

That finding became important because it demonstrated that Preston had suffered a significant injury before the fatal incident.

The evidence therefore challenged any suggestion that everything could be explained by a single accident on the day he died.

THE FINAL DAY

On July 27, 2023, Preston was taken to Blackpool Victoria Hospital.

He was unconscious and in cardiac arrest.

Medical staff fought to save him, but he was pronounced dead shortly afterward.

The post-mortem examination established the cause of death as acute upper-airway obstruction. The CPS said this meant Preston had been smothered or that something had been placed in his mouth and caused the obstruction.

That finding became a critical turning point.

Varley had claimed Preston had accidentally drowned in a bath.

But prosecutors presented expert evidence showing that Preston’s injuries were inconsistent with that explanation.

The accident story could not withstand the forensic evidence.

THE TIMELINE MATTERED

The prosecution’s case was not simply that Preston suffered a fatal medical emergency.

It was that his condition had developed against a much larger background of injuries and abuse.

The evidence included:

• Around 40 separate injuries
• A non-accidental healing arm fracture
• Bruising to multiple parts of his body
• Medical evidence consistent with sexual assault
• Photographs and videos recovered from phones
• Messages and other digital evidence
• Evidence concerning the circumstances immediately before his death

The CPS said medical evidence indicated sexual assault had occurred both shortly before Preston’s death and at an earlier point during the weeks before it.

THE ADOPTION HOME BECAME PART OF THE QUESTIONS

Perhaps the most painful element of the case is how Preston came to be living with the defendants in the first place.

He had spent his early months in foster care before being placed with Varley and McGowan-Fazakerley for adoption.

The adults responsible for him were therefore supposed to provide safety and protection.

Instead, prosecutors said the evidence demonstrated a prolonged period of abuse.

That has inevitably raised broader questions about safeguarding and whether warning signs should have been recognized earlier.

THE DEFENSE COLLAPSED UNDER THE EVIDENCE

Varley denied causing Preston’s injuries and attempted to explain his death as an accident.

But prosecutors had to establish more than the fact that Preston had been injured.

To secure a murder conviction, they needed to prove that Varley intended to kill Preston or cause him serious harm and that his actions caused the child’s death.

The CPS said expert evidence established that Preston’s condition could not have been caused by accidental drowning or a natural cause.

Jurors ultimately rejected Varley’s account.

On June 15, 2026, he was found guilty of murder along with numerous other offenses.

JUSTICE FOR PRESTON — AND A QUESTION FOR THE SYSTEM

Varley was later given a whole-life order, while McGowan-Fazakerley received a lengthy prison sentence.

But the verdict did not erase the questions surrounding Preston’s final months.

How did a baby who was placed into a prospective adoptive home suffer so many injuries?

Could earlier warning signs have triggered intervention?

And how many of the injuries documented after Preston’s death could have been prevented?

Those questions now sit alongside the criminal convictions.

THE MOST IMPORTANT EVIDENCE WAS THE STORY TOLD BY TIME

One photograph might show an injury.

One medical record might document a hospital visit.

One video might capture a disturbing moment.

But when investigators placed the evidence in chronological order, prosecutors argued that a much larger picture emerged.

The injuries were not simply evidence of what happened to Preston on his final day.

They became evidence of what investigators said happened during the weeks leading up to it.

And ultimately, the forensic evidence gave Preston something he could no longer provide himself:

a timeline.

A timeline showing that his final tragedy did not begin when he was taken to hospital.

According to the evidence presented in court, it had been unfolding for weeks.
