The police are reviewing CCTV footage showing men who they believed chased and shot dead national under-19 representative and former popular schoolboy footballer, Omar Laing on Friday in downtown Kingston.
The two-minute video showed men exiting a grey motorcar and then chasing the 18-year-old Laing for a few blocks on Charles and Orange Street.
The teenager tried to escape but later fell after he was shot several times.
The attacker then returned to the waiting vehicle and escaped.
Police sources said they are reviewing the video to ascertain its authenticity and to also identify the attackers.
