Last updated 23rd May 2023
A Stockton man has been given a life sentence, with a minimum term of 29 years in prison for the murder of Sunderland schoolgirl Nikki Allan, back in 1992.
Last week, David Boyd, 55, of Chesterton Court in Norton, was found guilty at Newcastle Crown Court of the murder of 7 year old Nikki.
Her body was discovered in the then-derelict Old Exchange Building near to her family home at Wear Garth. She had been badly beaten and stabbed multiple times.
A neighbour of Nikki and her family, Boyd hid his heinous crime for more than three decades – compounding the family’s grief and despair.
After sentencing, Nikki's mum spoke outside to say she feels let down by the justice system and that she will be calling for a public enquiry into the police's handling of the original case.
"I would have been satisfied with life (a whole life term).
"This is a seven-year-old bairn.
"When is anyone going to take crimes like this seriously?
"This is what happens to families like mine over and over again - injustice."
Standing next to Ms Henderson, Harriet Wistrich, director at the Centre for Women's Justice, said: "Now, Sharon demands that Northumbria police are held accountable for their historic failures that allowed a 31-year wait until the right man was convicted of Nikki's murder.
"The full extent of the failures remain unknown and therefore we are demanding a public inquiry to examine the historic investigation which led to the wrong man being prosecuted and the police failing to consider alternative suspects until over 20 years later.
"We are also preparing a complaint to be lodged with the Independent Office of Police Complaints and exploring a civil claim for damages on Sharon's behalf."
And after the case George Heron, the innocent man who was wrongly charged with Nikki's murder and cleared in 1993, said: "Finding out about the current investigation has been difficult - so many details and negative memories; bringing up mixed emotions about what happened back in 1992 and since.
"I feel sadness, disgust, anger, betrayal by people I expected to tell the truth (especially the original investigating officers)."
Boyd was convicted of murder earlier this month after jurors heard he battered her with a brick and stabbed her in the chest 37 times, then left her dead or dying in the basement.
Mrs Justice Lambert found that Boyd lured her away to the Old Exchange Building from the relative safety of the Garths flats, where she lived, that October night in 1992 to sexually assault Nikki, or to try to.
She screamed and Boyd hit her on the lip and forced her through in a window, six feet off the ground, into the the building.
The judge said: ""She must have quickly known she was trapped.
"She must have quickly known you were coming after her to hurt her.
"It was cold and dark. It must have been a truly terrifying experience for this seven-year-old girl."
The fatal attack happened at the furthest point away from the window, indicating Nikki had tried to escape him.
He then dumped her in the cellar, hoping she would not be discovered.
Boyd remained at large while innocent Mr Heron stood trial for the killing, before he was acquitted on the orders of the judge in 1993.
Boyd was free to indecently assault a nine-year-old in a Teesside park in 1999 and he later told his probation officer he had previously had sexual fantasises about "young girls".
In a victim statement read on her behalf, Ms Henderson said: "I'm 57 and I've spent more than 30 years fighting for justice.
"My life and that of my family has never been the same since Nikki was murdered.
"By murdering Nikki, David Boyd destroyed the life of my beautiful daughter, my life and the lives of my daughters and grandchildren.
"We have not been able to live normal lives since that day."
Jason Pitter KC, defending, said Boyd had learning difficulties and has been assessed as having an IQ in the bottom 2% of the population.
Mr Pitter also said it was not the defendant's fault that Mr Heron was accused of Nikki's murder.
After Boyd was convicted, Northumbria Police detective chief superintendent Lisa Theaker said: "First and foremost, my thoughts are with Nikki's family. I would like to thank them for their patience and strength shown during their relentless pursuit of justice.
"The pain and suffering that David Boyd has caused to so many people is beyond measure.
"As an investigative team, we have worked tirelessly to find the person responsible - and crucially prove that it could only have been Boyd who murdered Nikki that night."
It was advancements in science which made it possible for police were to detect a DNA profile on Nikki’s clothing that matched Boyd when the case was reviewed in 2017.
Assistant Chief Constable Brad Howe, of Northumbria Police, said: “Today is about justice – for Nikki and her family.
“We thank them for their patience and strength over the last 30 years and our thoughts very much continue to be with them.
“David Boyd hid his crime, lying about his involvement and prolonging the family’s suffering, knowing all along that he had taken the life of their little girl.
“The investigation into Nikki’s murder has been one of the most complex and comprehensive ever conducted by Northumbria Police.
“I’m extremely proud of the investigative team and all those who played their part in securing this conviction. I further hope this sends a strong message that no matter how long ago an offence took place, we will do everything we can to see justice served.”
