Mohammed Umar Khan, 15, to serve minimum of 16 years for k!lling fellow pupil in Catholic school

A 15-year-old boy who stabbed fellow pupil Harvey Willgoose to de@th during a school lunch break has been sentenced to serve at least 16 years in jail. 

Mohammed Umar Khan, who can now be named following a judge’s ruling, took a hunting knife to school and stabbed the teenager in the heart in front of horrified children on February 3, 2025. 
 

Victim Harvey Willgoose 

Khan’s trial heard how other pupils fled “in fear and panic”, some locking themselves in a school cupboard, after the fatal attack at the All Saints Catholic High School in Sheffield. 

He was found guilty of murd£r in August, with Harvey’s sister, Sophie Willgoose, describing the k!lling as “not just a crime against my brother, it was a crime against all of us who loved him”. 

During his sentencing hearing at Sheffield Crown Court on Wednesday, Oct. 22, the defendant was told by judge Mrs Justice Ellenbogen: “You were the aggressor and… you acted in hurt and anger at what you considered to be his betrayal of your friendship.” 

On Wednesday, the judge agreed to lift an order banning Khan’s identification following applications from a number of media organisations, including the PA news agency. 

She told the court she had to balance the need to fully report a very serious case with the welfare of the defendant, who turns 16 next month. 

The judge said: “This was a serious crime carried out by one pupil on another on school property with a knife he brought into school. 

“It was witnessed to varying degrees by other pupils and teachers. 
 

“The public will wish to know the identity of those who commit such offences in seeking to understand how it is a child of that age can do so.” 

Harvey’s parents, Mark and Caroline, were watching from the back row of the public gallery with other family members, including his sister, Sophie. 

In her statement to the court, Harvey’s sister said her family are “struggling to comprehend the fact that Harvey was murd£red in the most cruel and inhumane way”. 

She said: “This was not just a crime against my brother, it was a crime against all of us who loved him.” 

Ms Willgoose continued: “The pain will remain with us for the rest of our lives. 

“We want justice not only for Harvey, but for the family that will carry his loss forever.” 

Ms Willgoose said the family were made to “endure” and are “haunted daily” by the CCTV footage of the k!lling because Khan “refused to take any responsibility” for what he had done. 

She told the court: “The defendant didn’t just end Harvey’s life, he ended ours too.”
