A 15-year-old has been sentenced to life with a minimum of 16 years behind bars after stabbing schoolmate Harvey Willgoose to death at lunchtime.
That’s how Caroline Willgoose, mother of murdered teenager Harvey Willgoose, described her emotions following the sentencing of her son’s killer 15-year-old Mohammed Umar Khan at Sheffield Crown Court.
Justice finally caught up with Khan on Wednesday when a judge lifted the anonymity order, revealing the face behind the shocking schoolyard tragedy. Khan, who brought a hunting knife into school, stabbed Harvey twice in front of fellow students one of the blows fatally piercing his heart.
Mrs Justice Ellenbogen didn’t hold back during sentencing. “You were the aggressor… you acted in hurt and anger at what you considered to be his betrayal of your friendship,” she told Khan.
The attack, carried out just after lunchtime began on 3 February, was captured on CCTV and shown to the jury. Khan had brought the knife to school that day, concealing it in his coat.
The violence was swift, brutal and witnessed by classmates. Khan was found guilty of murder in August.

The judge ruled that the severity of the crime overruled any argument for protecting Khan’s identity: “The public will wish to know the identity of those who commit such serious offences.”
Harvey’s mother expressed relief that justice had been served. “We just need to get on with our lives and try and do good things for our Harvey, for those kids. He doesn’t look like he’s sorry but I just hope that’s his mask,” she said.
Since her son’s death, Caroline and her family have been actively campaigning against knife crime, with a push to introduce knife arches into schools to protect pupils from similar fates.
The fatal stabbing of Harvey Willgoose has reignited national concerns over youth violence and knife crime in schools.
The case has prompted renewed calls for preventative measures in educational institutions, as campaigners demand action from policymakers to stop more children from being lost to such senseless violence.
What Led to the Deadly Fallout?
Jurors were told of a tense buildup between the boys. It started days before the stabbing when Khan intervened in a separate altercation at All Saints Catholic High School.
When he falsely claimed another boy had a knife, the school went into lockdown though no weapon was ever found.
Harvey, concerned for his safety, didn’t attend school for the rest of that week, texting his dad: “Am not going in that school while people have knives.”

Their friendship unravelled online over the weekend, with each teen siding with different boys involved in the incident. By Monday, when Khan returned to school, tensions were at boiling point.
Despite being asked if he had anything suspicious on him that morning, Khan denied carrying a weapon. Just after 12:10pm, at the start of lunch, he pulled out the knife and launched the fatal attack.
After the stabbing, Khan confessed to headteacher Sean Pender: “I’m not right in the head. My mum doesn’t look after me right.”
Assistant head Morgan Davis took the knife from Khan and later testified that the teen said: “You know I can’t control it” believed to be a reference to his previous episodes of violent behaviour at school.
Khan’s phone revealed disturbing evidence images and videos of him posing with knives and weapons, as well as internet searches on blades. He claimed he carried the knife out of fear, having convinced himself that other teens were armed.
His barrister, Gul Nawaz Hussain KC, argued that Khan had “snapped” after enduring years of bullying and living in constant fear.
A Family Shattered by Grief
Harvey’s family, including his sister Sophie, were present at the sentencing. Sophie told the court: “It was not just a crime against my brother, it was a crime against all of us who loved him.”
She remembered Harvey as a boy with “a cheeky character, a brilliant sense of humour and a warmth that made everyone love him.”
Caroline Willgoose revealed that the trauma of Harvey’s death had devastating ripple effects. Her father Harvey’s grandfather and “best friend” passed away last week.
“My dad couldn’t cope with the grief and he found out he’d got cancer just after. I said ‘this is going to kill my dad’, and it did,” she said.
The Bigger Picture: Tackling Knife Crime in Schools
The sentencing has once again highlighted the growing issue of knife crime among young people in the UK.
- Campaigners are calling for stricter security in schools, including knife arches and random searches.
- Mental health support for students showing violent tendencies is also under the spotlight.
- Parents, schools, and communities are urged to recognise early warning signs and act before it’s too late.
Mohammed Umar Khan will now spend at least the next 16 years behind bars. But for Harvey’s family, the sentence is just a step on a long road of grief and healing. “The pain will remain with us for the rest of our lives,” Caroline said.
