Two teenagers were jailed after they stabbed a 17-year-old boy to death outside a McDonald’s restaurant in south-east London last year. Yeray Sanchez Morales was with a friend on Old Kent Road just before 11pm on August 27 when he was attacked by a group of youths. He suffered nine wounds to his neck and chest and later died in the hospital a week after the incident. The Metropolitan Police said the attackers boasted about the crime by posting photos of their bloodied hands and knives on social media. Detectives used CCTV footage and clothing details to identify those involved and determine who delivered the fatal blows. Yeray’s friend, who survived the attack, said they did not know why they had been targeted. On Friday, four men and three boys were convicted of various charges related to Yeray’s death. Christhofer Jesus Vasquez, 18, was found guilty of manslaughter and received a four-year jail sentence. He had previously been jailed for one year for possessing a bladed article, which will run concurrently with his new sentence. Andres Tapia Londono, 18, was also convicted of manslaughter and received a four-year sentence. Isaac Ros Ramirez, 18, and Juan Betancourt Hoyos, 21, were found guilty of violent disorder and given community orders. A 16-year-old boy was sentenced to 16 months in jail for violent disorder, while a second 16-year-old received a 12-month youth rehabilitation order. A third 16-year-old was given a community order after pleading guilty to violent disorder and other charges. Yeray’s mother, Elena Morales, described her son as a sensitive, kind, and generous young man who loved to dance and sing. He had just completed the first year of a sports science course and dreamed of becoming a PE teacher. She said his death has left an unhealable wound in their family and that his absence is felt every day. “Yeray had his whole life ahead of him,” she said, adding that the pain of his loss crushes her soul. Detectives investigating the attack obtained mobile phone footage from witnesses and used social media to track the suspects. One of the 16-year-olds was found to have booked a taxi to leave the scene shortly after the attack. A forensic team linked one individual to the crime through DNA found on the rim of a bottle used in the assault. Detective Sergeant Debbie Barge, who led the investigation, said Yeray’s death was a cruel act of violence that shocked the community. She thanked the teenagers who witnessed the attack for helping bring the perpetrators to justice and expressed hope that the convictions might bring some peace to Yeray’s family.
