The quiet suburban morning on Greyhound Lane in Stourbridge was shattered on March 30th, 2017, when a frenzied knife attack tore apart the Wilkinson family, leaving a mother and her teenage son dead and a father fighting for his life in a pool of blood. The attack, which police described as “truly horrific and heartbreaking,” was carried out by a 23-year-old man the family had taken in from the streets, a man they had fed, clothed, employed, and treated as their own son. Aaron Barley, the man who addressed his benefactor Tracy Wilkinson as “the mother I never had,” would repay their extraordinary kindness with a level of violence that shocked even seasoned detectives.
The nightmare began just after 8 a. m. when Peter Wilkinson, 47, returned from his customary morning walk with the family’s greyhound, Mandy.
He had asked his 13-year-old son, Pierce, if he wanted to join him, but the boy declined, saying he would go the following day. As Peter entered through the back door, expecting the usual cup of tea his wife Tracy always had waiting for him, he was ambushed. A man wearing a balaclava lunged from behind a wall in the kitchen, wielding a knife above his head.
The attacker stabbed Peter six times—twice in the back, twice in the abdomen, and twice in the face—while screaming, “Die you bastard.” Despite the disguise, Peter instantly recognized the voice and the eyes of the man he had tried so hard to save. “Aaron, we tried to help you,” Peter pleaded, but Barley simply repeated his chilling mantra and stabbed him again in the stomach before stealing the family Land Rover and fleeing the scene.
Peter, bleeding profusely, managed to call 999 before staggering into the garden and collapsing onto a chair. Emergency services rushed to the scene, with a paramedic arriving within seven minutes. As Peter was being treated, he begged the medics to check on his wife and son, who were still inside the house.
The paramedic’s face upon returning told him everything he needed to know. “One dead, one in cardiac arrest,” the paramedic said. Inside, the scene was one of unimaginable horror.
Tracy Wilkinson, 50, a former Latin American ballroom dancing champion and a woman known for her boundless compassion, had been stabbed at least 17 times. She was found naked on her bedroom floor, having been stabbed through her duvet as she lay in bed. She was pronounced dead at the scene.
Her son Pierce, described by his sister as “handsome, funny, and clever,” had been stabbed at least eight times, with one wound so severe it nearly divided his spinal cord. He had tried to crawl along the floor to escape his attacker, but he was found on his stomach, struggling to breathe. He was rushed to Birmingham Children’s Hospital, where doctors fought tirelessly to save him, but tragically, he succumbed to his injuries.
The attack left Lydia Wilkinson, the couple’s 22-year-old daughter who was studying biology at Bristol University, utterly devastated. She had been home just four days earlier to surprise her mother for Mother’s Day, hiding in the family’s Land Rover to spring the joyful ambush. She had returned to Bristol, promising her little brother she would be at the school gates to pick him up the following day.
Instead, she received a call from her boyfriend saying there had been an incident in Stourbridge. When she Googled the news, she saw photos of her home taped off with emergency services swarming the street. She called the police and was given the horrifying news that would obliterate her world.
“I went in and I just stayed with my mum and brother for a while and said that I was sorry I couldn’t protect them,” she later said. “I stayed there because I knew that was going to be the last time I saw them in my life.”
The family’s story with Aaron Barley began just over a year earlier, in March 2016, when Tracy spotted him sleeping in a cardboard box outside a supermarket. Seeing him struggling and cold moved her greatly. She took him home, gave him dinner, and was determined to get him back on his feet.
She drove him to the council offices to find accommodation, ensured he had hot meals every day, and eventually, her husband Peter gave him a job as a laborer in one of his businesses. Barley’s life had been chaotic from the start. Born in 1993 out of an incestuous relationship between an uncle and niece, he was orphaned by the age of six after his father died of cancer and his mother suffered a fatal heart attack.
He spent his childhood in care, suffering physical and sexual 𝓪𝓫𝓾𝓼𝓮. By 13, he was at the center of a missing person’s investigation. As he aged out of the system, he fell into homelessness, substance 𝓪𝓫𝓾𝓼𝓮, and alcoholism.
He had a string of 21 previous convictions, including grievous bodily harm, assaulting a police officer, and a horrific attack on a former partner whom he hit 50 times with a piece of wood before trying to stab her with it.
Despite this history, the Wilkinsons saw a broken man in need of a chance. Barley appeared grateful, spending Christmas Day with the family and giving Tracy a card that read, “To the mother I never had.” But the cracks began to show in September 2016 when he claimed he had relapsed into 𝒹𝓇𝓊𝑔 use, lying that his mother had died.
He became aggressive at work and was let go. The family lost contact with him, but he soon reappeared, sleeping in their driveway, covered in bruises after an apparent assault. They took him in again, found him a new flat, and he visited for dinner a couple of times a week.
But his job ended, he lost his accommodation, and the family let him stay in their house for two weeks in March 2017. Just days before the murders, the Wilkinsons canceled a phone contract they had been paying for him after he failed to contact them for three weeks. Tracy had told friends she had seen him looking over the fence and that she wanted nothing more to do with him.
CCTV footage later revealed the chilling premeditation of the attack. Barley climbed over the garden fence the night before the murders and hid in the garden shed. As morning broke, he waited for Peter to leave for his walk.
He then crawled across the garden, entered the unlocked home, pulled on a balaclava, and took two knives from the kitchen. He went upstairs and launched his frenzied attack on Tracy and Pierce in their beds before lying in wait for Peter to return. His lack of remorse was 𝓈𝒽𝓸𝒸𝓀𝒾𝓃𝑔.
After being arrested following a brief chase, he told a police officer, “I’ve stabbed three people up, I ain’t bothered about taking one of you with me.” He bragged about killing the mother and son, saying he was glad they were dead, and expressed regret only that he hadn’t succeeded in killing Peter. He refused to give a reason for his crime, and his motive remains unknown.
A prison nurse reported that when asked about being homeless, he said, “What, two murders and possibly a third? I don’t think I’ll need any help with that.”
The community of Stourbridge was left in a state of total shock. Flowers piled up outside the family home, and Pierce’s school paid tribute to a “loyal, caring, and conscientious” young man who was passionate about West Bromwich Albion and devoted to his pet greyhound. Lydia showed enormous bravery, returning to the house to lay flowers for her mother and brother.
She stayed by her father’s bedside in the hospital, holding his hand until he regained consciousness. Peter survived, spending 11 days in the hospital, six of which were in intensive care, before being told the devastating news that his wife and son were gone. At the funeral, Pierce and Tracy shared a coffin, their bodies inseparable in death as they were in life.
The service was held at Saint Mary’s Church, with the family’s dog Mandy and other rescue dogs forming a guard of honor.
In court, Barley pleaded guilty to two counts of murder and one count of attempted murder. He rocked from side to side in the dock before shouting, “I’ve done what I’ve done, there’s no need to stand here and lie.” Psychiatric tests determined that nothing could provide a defense on the grounds of diminished responsibility, though he was diagnosed with borderline personality disorder.
His defense lawyer argued that Barley perceived the family had turned their back on him, though he admitted there was no evidence to substantiate this. The prosecution described Barley as a “compulsive liar” and a “manipulator,” with former carers describing him as a “Jekyll and Hyde” character. Lydia addressed the court with a powerful victim impact statement, telling Barley, “My parents helped you.
You repaid them with destruction and heartache. You have obliterated my life, murdered half my family, very nearly all of it. I’m a shell of my former self.
Sometimes I wake up and don’t want to be here.” She said she would never forgive him. Barley appeared to cry and mouthed the words “I’m sorry,” but the judge, Mrs.
Justice Carr, noted his lack of genuine remorse.
The judge sentenced Barley to life in prison with a minimum term of 30 years, later increased to 35 years on appeal by the Solicitor General, who argued the original sentence was unduly lenient. The appeal judges ruled that due to the “most exceptional grave case,” the minimum term needed to be increased. Barley will only become eligible for parole once he has served his minimum term and can prove he is no longer a danger.
He may never be released. Lydia, displaying a resilience that has inspired many, has channeled her grief into positive action. She returned to university to continue her studies, aiming to become a medical researcher to “continue the help and support that my mom would give to people.”
She raised £13,000 for Birmingham Children’s Hospital, the hospital that tried so hard to save her little brother. Teachers from Pierce’s school ran a marathon in his memory, raising £3,550 for the Greyhound Trust, his favorite charity. Peter and Lydia moved back into the family home on Greyhound Lane, determined not to let Barley take anything more from them.
“It’s our home,” Peter said. “After taking so much from us, we couldn’t possibly have it that he would take anything else.” The house was later put up for sale in February 2018, as the family sought to move forward.
Lydia has spoken about the importance of helping others but has urged people to go through official charities and organizations rather than taking people into their homes directly. “My mom and dad did an amazing thing and I would never discourage anyone from helping others in a similar way,” she said. “But I would always encourage people to go through the charities and organizations specifically set up for that type of thing.
These charities know the system and they have the correct vetting processes in place.” She has said she does not feel hatred for Aaron Barley, choosing instead to channel her energy into building something positive from the tragedy. The loss of Tracy and Pierce is immeasurable, and the pain for those who knew and loved them is incalculable.
Tracy was a generous and compassionate woman who refused to turn away from anyone in need, and she and Peter raised two incredibly kind and thoughtful children. The void left by their deaths will never be filled, but the lasting legacy they have created—through the children who will be cared for by Birmingham Children’s Hospital and the greyhounds who will find new homes—will live on for many years to come.
