The prosecution alleged the three defendants were captured on Ring doorbell footage walking along a path leading to Eglinton Road and are said to have gone into an address at number 91.
A minute later Daejaun had walked past the same address and “would have been in clear view of anyone looking out of the windows,” said Mr Chawla.
Shortly afterwards the 17-year-old defendant was recorded walking towards Eglinton Road dressed in a black t-shirt, black trousers and a black balaclava, with the defendant Balaz following behind.
Eyewitnesses saw Daejaun Campbell running up the path apparently being chased by two males and heard a female voice shout “he’s been stabbed.”
The prosecution said a witness had heard Daejaun screaming and calling for “help” as he was stabbed.
