Latest from the Old Bailey:
On the day of the killing, Kwame and his friend had gone to to a music studio in Brixton.They were about to head to Denmark Hill train station when the friend remembered he had to collect a bag from an aunt who lives on the Moorlands Estate.
The jury heard that on their way there, the pair bumped into two boys on bicycles they knew by sight, who warned them there were youths in the area "acting suspiciously". A witness saw how the four suddenly separated, with the two on foot running and the two on bikes riding away at speed.
Chased down Adelaide Close, Kwame and his friend knocked on the aunt's door but she was out.
The friend urged him to jump over a 6ft wall to escape, but Kwame didn't follow. From behind the wall, he could hear Kwame pleading: "I'm not from round here".
The two defendants deny murder.
