Prosecutor Zoe Johnson KC had told jurors the background to the murder was linked to drug dealing and Mr Scott had been operating on rival territory.
Dualla Abdi, 20, failed to ditch the luxury accessory he was carrying when he fatally stabbed Tyreece Scott, 24, in Hounslow, west London, shortly before 1am last January 16.
Ms Johnson asserted that Abdi and Laing had worked as a team with a common purpose when Mr Scott was stabbed.
At their Old Bailey sentencing, members of Mr Scott’s heartbroken family spoke of the young man they knew as kind, gentle and loyal, with “big hopes and dreams”.
At the time of the stabbing, Abdi was wearing a black hooded jacket with a “Trapstar” logo in white on the front of the jacket and a Louis Vuitton manbag with a distinctive buckle on the strap, jurors heard.
