A teenager who murdered a schoolboy, Baptista Adjei in Newham can now be named.
The restriction was lifted at the Old Bailey Court where the 16-year-old Marvin Dyer was on Friday, jailed for life with the possibility of parole after serving 16 years.
CCTV footage captured aboard the bus saw Dyer, then aged 15, boarded the bus at Stratford Broadway and calmly pull a balaclava over his face while wearing a blue latex glove.
Dyer waited for Baptista and his friend to alight from the bus before stabbing him twice on the chest. He then turned his attention to his friend dealing another cut with his 10″ combat knife.
The attack reportedly lasted for nine seconds but inflicted two fatal wounds on Baptista and his friends while Dyer held on to the handrail.
Investigators report showed two stab wounds on Baptista’s chest. The blade punctured his lung and his heart. Despite the severity of his injury, Baptista was able to run as far as Stratford Centre before collapsing.
What Led To The Beef
Findings revealed that the victims and his 15-year-old friend were involved in an online disagreement in a Snapchat group chat, two weeks before the murder.
Dyer was only vaguely known to them, outside of the online forum, having seen the boys around the Stratford area, detectives revealed.
The interaction was said to have begun as a mutual banter before it eventually turned ugly.
The boys taunted each other, resulting in a brief hot exchange online. Dyer had messaged Baptista saying “If you have got no bodies on your blade, leave the group chat,” in which Baptista had replied “Shut up. You’ll be the first.”
The exchange between the murderer and the victim continued ending in Dyer threatening to be outside the victim’s school the next day at 15:25hrs.
He, however, wasn’t there as he threatened, but Dyber struck weeks later, on the day of the murder, October 10 2019, when Baptista and his 15-year-old friend took the bus towards Stratford.
Despite paramedics effort, Baptista died from his injuries at the scene at 15:49hrs.

Unlike Baptista, his friend who suffered stab wounds on his arm and in the leg was taken to an East London hospital by the London Ambulance Service where he remained for almost a week. He had since made a full recovery, the Met Investigators disclosed.
Detective Inspector Chris Soole launched a murder investigation following Baptista’s death.
Members of Marvin Dyer’s family who had heard of the incidents confronted Dyer on 11 October 2019. He reportedly admitted the attack on both victims and was subsequently dragged to police at Forest Gate police station by his mother.
The following day, Dyer was charged with Baptista’s murder, grievous bodily harm with intent in connection to the second 15-year-old victim and two counts of possession of an offensive weapon.

On Tuesday, 11 August 2020, Dyer and a second 16-year-old boy had appeared at the Old Bailey Court where he was convicted of murder and wounding and the second defendant was found not guilty and released.
Baptista’s mother in a victim impact statement said the family “can never get over Baptista’s death” but hope and pray that “with time the constant pain that we feel subsides.”
“Ours and Baptista’s plans were always that he would finish school and move on to higher education, get married and if he was blessed, to have children and make me a grandmother.
“His dreams, together with mine, will never happen because he was taken from us in such a cruel way.
Detective Sergeant Susanne Soren said “It is sad and concerning that such extreme violence was used to resolve such minor conflict – nothing more than name-calling.
“The sentence handed down today will not bring back Baptista. His loved ones will not be healed by the knowledge that justice has been served. They will remember and miss him every day in the years to come.
“Similarly, Marvin Dyer’s family’s lives have been changed forever, their only comfort being that they did the right thing in holding him to account and presenting him to police.
“My thoughts are with everyone touched by this most tragic and needless of incidents and I hope that anyone involved in knife crime and violence takes something from this outcome – nothing is worth the price that will be paid for murder and ultimately, that price is paid not only by the perpetrator and the victim but also their families.”
