– Crispin Aylett QC, prosecuting, told jurors
Kwame's death was but a part of a poisonous and senseless feud between two rival gangs of youths in south London.
He added that Kwame was not a member of either gang. He had been to a recording studio in the area.
Kwame was stabbed repeatedly in the back and received a total of 14 wounds while walking in Adelaide Close with a friend.
The killers tried to get away by going into a side road where the friend's aunt lived, but the aunt was not home and they were trapped in a cul de sac.
