Bernadette Walker: The murder conviction without a body
17-year-old Bernadette Walker got into the car with the man she had known for most of her life. Her stepfather. In July 2020, the teenager was never seen again. Scott Walker was the last person to see her alive.
But what happened to the photography student?
The teen from Peterborough had spent the previous night at her grandparents' home. That morning, Mr Walker arrived to drive her back to the family house. According to his version of events, Bernadette suddenly asked him to pull over, got out of the car, and ran away.
Crime+Investigation examines what happened that morning, how investigators built a murder case without a body, and why Bernadette's family still cannot lay her to rest.
The secret that changed everything
In the days leading up to Bernadette’s disappearance, she had revealed something that would eventually give investigators the key to understanding what had happened to her.
The student told her mother, Sarah, that Scott Walker had been sexually abusing her for years.
According to evidence heard during the trial, Bernadette had spoken about hidden cameras in the family home and described years of abuse. She wanted to report the allegations to the police.
Prosecutors argued that Scott Walker saw only one way of preventing that from happening. Their case was that he murdered Bernadette to silence her before she could expose him. It was a motive that explained not only her disappearance, but everything that followed.
The story begins to unravel
Three days after Bernadette was last seen, Scott and Sarah Walker reported her missing.
Scott claimed he had dropped her off after she became upset and walked away from the car. He even publicly appealed for her safe return, sharing missing person appeals on social media and encouraging others to help search for her.
Meanwhile, police were already finding cracks in Scott’s story.
Phone records showed Scott Walker had switched off his mobile phone during the period when prosecutors believed Bernadette was killed. CCTV and location data also contradicted parts of his account.
More significantly, investigators discovered that, instead of driving directly to collect Bernadette, Scott had first visited a lock-up garage owned by his parents. He returned there several times after she disappeared.
Covering up the truth
One of the strongest pieces of evidence against Scott Walker came from what happened after Bernadette vanished.
Messages continued to be sent from her mobile phone, creating the impression that she was still alive and had chosen to leave home voluntarily. Prosecutors argued these messages were not written by Bernadette at all.
Instead, they said Scott and Sarah Walker had worked together to stage her disappearance, attempting to convince family members, friends and police that she had simply run away. The prosecution described the pair as an ‘unholy alliance’, united in their efforts to conceal what had happened.
The deception extended beyond text messages. Scott continued making public appeals for Bernadette to return home, despite prosecutors arguing that he already knew she was dead.
How do you prove murder without a body?
One of the biggest challenges facing prosecutors was obvious. Bernadette had never been found.
Without a body, there was no forensic examination, no confirmed cause of death and no crime scene that could explain exactly how she had been killed.
Instead, the case relied on what lawyers call circumstantial evidence. Piece by piece, prosecutors built a timeline showing that Bernadette had simply disappeared from the world.
She stopped using her phone, her bank accounts remained untouched and there was no evidence that she had started a new life elsewhere. Friends and relatives never heard from her again.
When this evidence was combined with Scott's lies, the fake text messages, Walker’s suspicious movements, the switched-off phone and Bernadette's allegations of abuse, there was only one reasonable conclusion. Scott Walker had murdered his stepdaughter.
Justice without closure
In July 2021, a jury at Cambridge Crown Court found Scott Walker guilty of Bernadette's murder and perverting the course of justice.
Bernadette’s mum, Sarah Walker, was convicted of perverting the course of justice after helping to cover up the crime.
Two months later, Scott was sentenced to life imprisonment with a minimum term of 32 years. During sentencing, the judge said his refusal to reveal where Bernadette's body had been hidden meant she could not be laid to rest with the dignity she deserved.
In December 2023, Scott Walker died in prison from cancer.
