A 16-year-old boy has been found guilty of murdering 16-year-old Joshua Ingram in Seaford, East Sussex, over a £20 drug debt12:24, 05 Aug 2026Updated 12:35, 05 Aug 2026A teenager who murdered a 16-year-old boy at a train station said he was "ready to sit in a prison cell for 30 years over a £20 sheet" in a Snapchat message sent before the attack.‌The defendant, 16, who cannot be named for legal reasons, was found guilty on Wednesday of murdering Joshua Ingram, who was fatally stabbed at Seaford railway station in East Sussex on September 10, 2025.‌The defendant was on trial at Hove Crown Court alongside two other boys, aged 17 and 15. All three were accused of conspiracy to cause grievous bodily harm with intent between June 1 and September 11, in the period leading up to the attack. Jurors found all three not guilty of that charge.‌The 15-year-old was found guilty of assisting an offender on the day of the murder. The 17-year-old had already pleaded guilty to the same charge.The prosecution told jurors that the 16-year-old defendant was a "small-time drug dealer" who had supplied Joshua with drugs in the summer of 2025 but had not been paid.‌Snapchat messages sent in the months before the stabbing were read in court. In one message, the teenager convicted of murder said: "Josh will perish if I don’t get my f****** money, that’s a fact and he knows this."I'm ready to sit in a prison cell for 30 years over a £20 sheet."Prosecutor Rossano Scamardella KC said the 16-year-old went to Seaford on the day of the attack with a 19cm-long knife hidden in his tracksuit bottoms. He then approached Joshua, who was from Newhaven, and stabbed him twice.‌The prosecutor said: "Joshua stood no chance. The speed of the attack from behind gave him no chance to defend himself and the injury he sustained was so serious that he could not survive."He collapsed on the station platform and despite the very best attempts by members of the public and emergency workers, he died within an hour of being stabbed and even before he could be taken to hospital."He added: "All of this over a £20 cannabis debt."‌The 16-year-old had pleaded guilty to an alternative charge of manslaughter and, giving evidence during the trial, said it was a "tragic and reckless moment".The teenager told jurors he viewed the 19cm knife as an "accessory" that he had bought on Telegram, but said he "didn’t look at it for what it actually was" and never intended to kill or seriously harm Joshua.The court also heard that the teenager had owned the knife used to kill Joshua since Year 9 and would "wave it around and playfully intimidate" others with it at his house.‌In the fatal attack in September, Joshua suffered a 15cm-deep stab wound.Giving evidence at the trial, Joshua's friend, who was with him when he was stabbed, said he saw the attacker take the knife out with "no hesitation" and stab Joshua twice.The friend said the defendant asked: "Is that Josh?" before he pulled a knife from his right hip, "went for it twice" and ran away.‌He said: "He had no hesitation - he had a very still facial expression, he wasn’t pulling a face, he didn’t look like he had anger in him. He looked very calm and just normal, but then just did that. I don’t think Josh even knew what had happened."The friend described how Joshua walked a couple of steps and then "dropped to the floor" as he tried to call 999.In a tribute released by Joshua's family after his death, they described him as a "cheeky chappie who was loved by many" and who was taken "far too soon".Article continues belowThe defendants will be sentenced on October 2.
