In December 2022, 23 year old Justice Beckford stabbed Kallon through an open car window after an altercation.
Kallon and his friend drove to Kings College Hospital to speak medical attention, but died a short time later.
CCTV from that night led officers to Beckford’s address where they found a black coat with Kallon’s blood on it.
Justice Beckford was found guilty of murder and possession of a blade or sharply pointed article and will be sentenced later this month.
