According to Bridgwater Mercury, Koporo stabbed Tyrone Mulinde through the heart at a flat in Bridgwater, carried over by a London gang as a base for drug dealing.
Moreover, Koporo allegedly plotted the attack with teenager Olivia Cromwell, who was linked and working as a dealer for Mr. Mulinde in Yeovil. Further, the partner was angry with Mr. Mulinde over the dealing, and Koporo attacked him within minutes of arriving in Bridgwater to meet him, as Exeter Crown Court was told.
