Cole, aged 18, was fatally shot once in the chest on Chesham Road following a pursuit between two cars on the evening of Wednesday 12 August 2020.
A jury at Manchester Crown Court (Crown Square) found Kamran Mohammed, Mohammed Izaarh Khan, and Khayam Ali Khurshid – all from Bury – guilty of Cole’s murder.
Raheem Hall , from Heywood, pleaded guilty to assisting an offender.
All four are expected to be sentenced in April 2021.
The court heard how all three men were in a silver BMW that was pursuing a Ford Mondeo that Cole and four others were in, and three shots were fired – the third of which fatally struck Cole shortly before 9.30pm.
He was taken to hospital but sadly passed away in hospital later that evening.
Over 350 hours of video footage, including 75 CCTV cameras, were meticulously viewed through the course of GMP’s Major Incident Team’s investigation, and over 250 people were spoken to as part of the operation – codenamed Landseer.
Speaking after today’s verdict, Detective Chief Inspector Andy Butterworth, from GMP’s Major Incident Team, said: “Today justice has been served for young Cole Kershaw and his family.
“Cole has been at the centre of this investigation throughout and we have done all we can to ensure that those responsible for his callous murder are held to account.
“They now face a lengthy spell behind bars, but that will never bring Cole back to his family and loved ones, and my thoughts remain with them this evening.”
