The parents of two grammar school pupils killed in a high-speed crash have paid tribute to their 'beloved' sons - after the car's driver was jailed for just 14 months.

Madeleine Lonsdale, 18, misjudged a bend along a country road near Grantham, Lincolnshire on June 20, 2025 as she reached speeds of up to 100mph.

Harrison Carter, 18, and George Stephenson, 17, were passengers in the vehicle and suffered fatal injuries in the impact of the collision.

Just hours earlier, the boys had spent the day celebrating with friends after finishing their A-level exams.

Their families have now opened up about the 'immeasurable loss' they have faced - saying waking up and remembering the teenagers are gone brings 'fresh pain' every day.

Harrison's parents, Sarah and David, said: 'Our beloved son, Harrison (Harry), was also a devoted brother to Owen and William, acting as their protector, encourager, voice of reason and confidant.

'He was resilient, generous without needing applause, authentically charming, honest and humble. He was motivated by meaning, not ego.'

George's parents, Vicki and Bruce, also shared a moving family tribute.

They said: 'As a family, we continue to be devastated by the loss of our youngest child, George, and know that this pain is something that we will endure for the rest of our lives.

'We are grateful for the 17 wonderful years that we had with him and will remember him for the love and laughter he brought, not just to our lives, but also to many others.

'George was a lovable, witty and intelligent young man who cared deeply about his friends and loved ones, often putting his own needs behind those of others.

'He was unassuming and modest, preferring to minimise his own achievements, and he acted as his friends' greatest cheerleader.

'He enjoyed spending time with his friends, socialising, and the freedom that passing his driving test gave him.'

Lonsdale, who only passed her driving test at the third attempt three months before the crash, partied 'repeatedly' and choreographed TikToks in the months after the teenager's deaths, a court previously heard.

She was sentenced to 14 months in a young offenders institution.

The crash took place in the early hours of June 20 last year near Grantham as the group returned from Rutland Water reservoir, where they had gone swimming. 

Lonsdale, at the wheel of a Kia Niro EV4 bought by her father, was being followed on the A1 by a friend who she later admitted to 'effectively racing', reaching speeds of up to 100mph.

After stopping for alcohol, vapes and snacks, both vehicles turned off the dual carriageway onto a rural road as they headed home, with Lonsdale accelerating to around 76mph.

But the teenager, who was travelling in front, failed to notice a sign warning of a bend.

Instead her car left the road at the beginning of the right hand bend and went onto a rutted area near a farm before hitting a tree and was then thrown back onto the road.

She was able to get out after sustaining only a fractured wrist in the 1.46am impact, but both boys were trapped and unconscious.

The 18-year-old stopped a passing motorist for help, but he could see 'they were motionless and believed they were already deceased,' the prosecution said.

A pathologist later concluded both boys would have been rendered unconscious immediately due to their head injuries.

Both were pronounced dead at the scene, near the village of Marston.

Harrison's parents also revealed he was a champion golfer, a well-respected member at local golf clubs, and had attended school at St. Nicholas Primary School, Cottesmore before studying at the Kings School, Grantham.

He was a member of the Law Society and Debate Club, where he would 'passionately and enthusiastically analyse complex issues with a natural curiosity'.

His parents said: 'He fostered compassion and empathy and had an intense understanding of fairness and respect.

'He achieved excellent GCSE and A-Level Results, adoring philosophy and ethics which he intended to study at Durham university, with a view to pursuing a career in Law.

'Harry had the most wonderful smile and the biggest heart giving love and time unconditionally to anyone who needed it.

'Harry saw the good in everyone and made a lasting impression on those whose lives he touched.'

They added: 'Whilst the loss we feel is immeasurable, we also recognise that grief is the price we pay for love. Harry leaves a legacy of pure kindness - we could all benefit from being a little more like Harry.

'Finally, we would like to take this opportunity to again thank the Police, the emergency services, Lincs and Notts Air Ambulance and the Kings School, Grantham to whom we extend our deepest gratitude, alongside our unwaveringly supportive family and friends, who have been our pillar of strength in recent months.'

George's parents revealed he was a water polo player for Grantham Water Polo Club, The Kings School, and the East Midlands region, and that he would travel the country for matches and tournaments.

He worked with a range of coaches and team members, and had intended to join the water polo squad at the University of Sheffield, where he planned to study psychology.

They said: 'He achieved above the necessary grades in his A-Levels, gaining A*, A and B; but, sadly, he never got the chance to enjoy university life.

'Losing George in such a senseless and traumatic way has shattered our family.

'He was the final part of our jigsaw puzzle, and, without him, we can never be complete.

'There is now a numbness in our lives, as we have already experienced the worst thing that could happen to us.

'Waking up each day and remembering that he is gone brings us fresh pain, and the knowledge that we will never hear his voice, see his smile, or be enveloped in one of his wonderful hugs is utterly heartbreaking.

'George was generous, charming and kind, and he brought joy and laughter wherever he went.'
