DAVID BOYD’S APPEAL REJECTED AFTER LIFE SENTENCE FOR THE 1992 MURDER OF 7-YEAR-OLD NIKKI ALLAN

More than three decades after seven-year-old Nikki Allan was killed in Sunderland, the man convicted of her murder has failed in his attempt to challenge his conviction and sentence.

David Boyd’s application for permission to appeal was rejected in October 2024, meaning his conviction and life sentence remain in place. The case did not proceed to a full Court of Appeal hearing.

Nikki was murdered on October 7, 1992, after disappearing from the Wear Garth area of Sunderland. Her body was later discovered inside the abandoned Old Exchange building.

For more than 30 years, her family lived without knowing who was responsible.

A CASE THAT REMAINED UNSOLVED FOR DECADES

Nikki knew Boyd, who lived close to her family and was the boyfriend of a woman who had babysat her.

According to evidence heard at trial, Nikki was seen walking with Boyd on the night she disappeared. Prosecutors said he lured her toward the derelict Old Exchange building, where she was sexually assaulted and killed.

The original investigation, however, focused on another man, George Heron.

Heron was prosecuted in 1993 but was acquitted after the case against him failed.

The investigation into Nikki’s murder subsequently remained unresolved for decades.

An independent investigation was later launched into the handling of the original police inquiry. The Independent Office for Police Conduct was asked to examine whether opportunities had been missed to identify Boyd earlier, including the possibility that DNA opportunities had not been properly pursued.

THE DNA BREAKTHROUGH

The case eventually changed as forensic science developed.

During the renewed investigation, detectives identified Y-STR DNA on clothing Nikki had been wearing that matched Boyd’s profile.

The sentencing judge described the DNA evidence as powerful when considered alongside the other evidence in the case. The court heard that the profile was not necessarily unique to Boyd because it could potentially be shared by male relatives or, less likely, unrelated men. Investigators nevertheless ruled out the possibility of another male relative being in the Sunderland area at the relevant time, while other evidence also raised questions about Boyd’s original account to police.

The new forensic evidence helped detectives build a case more than 30 years after Nikki’s death.

CONVICTED AFTER 31 YEARS

Boyd was eventually arrested and prosecuted.

On May 12, 2023, a jury at Newcastle Crown Court found him guilty of Nikki’s murder.

He was sentenced several days later to life imprisonment, with a minimum term of 29 years, after taking into account time already spent in custody.

The sentencing judge said the murder was of particularly high seriousness.

The court heard that Nikki had been taken to the derelict building, where Boyd intended to sexually assault her. The judge concluded that he had used Nikki’s trust and young age to lure her away.

BOYD CHALLENGES THE CONVICTION

After his conviction, Boyd sought permission to appeal both his conviction and sentence.

His legal team lodged the application in September 2023.

But in October 2024, the Court of Appeal rejected the application. ITV reported that the case did not proceed to the full court, leaving Boyd’s conviction and life sentence unchanged.

He therefore remains in prison under the life sentence, with a minimum term of 29 years.

A FAMILY’S 30-YEAR WAIT FOR ANSWERS

For Nikki’s mother, Sharon Henderson, the case was never forgotten.

For decades, she continued pushing for the investigation to be revisited and provided information she believed could help detectives identify Nikki’s killer.

The eventual conviction in 2023 brought a legal conclusion after more than three decades of uncertainty.

But the case also raised difficult questions about the original investigation and whether Boyd could have been identified much earlier.

Those questions became the subject of an independent police watchdog investigation following his conviction.

THE CASE THAT DNA HELPED REOPEN

Nikki Allan’s murder remained unsolved through changing investigators, an unsuccessful prosecution and more than 30 years of unanswered questions.

Modern forensic techniques eventually gave investigators evidence that was not available in the same form when the original investigation began.

The result was a conviction decades after the seven-year-old girl was found dead.

And when Boyd later attempted to challenge that conviction, his application was rejected.

For Nikki’s family, the journey to the truth took more than 30 years.

A little girl disappeared in Sunderland in 1992. It took until 2023 for a jury to finally determine who was responsible — and until 2024 for Boyd’s attempt to challenge that conviction to be rejected.
