Elijah (R) was stabbed and disembowelled in a street attack, which was caught on CCTV
The victim, from nearby Higham Hill, east London, suffered massive blood loss and was pronounced dead in the early hours of the morning.
Prosecutor Jonathan Rees QC told jurors the stabbing on the evening of May 7 was caught on CCTV footage, which would be played in the trial of the two alleged killers.
Ezra Abeka-Soares, of Caxton Road, Southall, Middlesex, and Morgan Mockford, of Randolf Road, Walthamstow, both 18, deny murder.
The trial is taking place at the Old Bailey, and both defendants deny murder
Elijah Dornelly’s friend managed to escape and run away, but Elijah Dornelly was not so fortunate
Mr Rees said: “The allegation is that just before 11.30pm on Sunday, May 7, in Walthamstow High Street, Elijah Dornelly and a friend were ambushed by these defendants, both of whom were armed with knives.
“Elijah Dornelly’s friend managed to escape and run away, but Elijah Dornelly was not so fortunate.
“Whilst he managed to dodge the first blow from Ezra Abeka-Soares, he was unable to avoid a lunge from Morgan Mockford who stabbed him, once, to the gut.
“Despite being fatally wounded, Elijah Dornelly ran off and made his way to the rear entrance of a shisha cafe called Arabian Nights.
“He ran inside and subsequently collapsed. His intestines were spilling out of his belly.”
The prosecutor said both defendants accepted being present but deny acting together to murder Elijah.
