On the night Carl was killed, he was with friends and had performed a set at the Club Life nightclub near Vauxhall station.
Within an hour of the attack, Okafor confessed in a phone call to his girlfriend that he had stabbed Carl, and days later he told the same woman that he had stabbed the DJ in the stomach. She said he gave her a pair of black gloves to look after which were later passed to police. DNA which may have come from the victim was found on one of the gloves.
Police arrived at his East Dulwich home on August 13, 2009 to arrest him but he was already in hiding and took a flight from Heathrow to Lagos using his brother's name and passport.
Sarah Whitehouse QC, prosecuting, told Woolwich Crown Court that Okafor had no connection with his victim prior to the attack. She said "It is not clear, and will probably never be known, what led up to the killing of Carl Beatson by Jeffrey Okafor. You may hear that there was some ill-feeling between some members of the two groups, but there was nothing serious enough in the background for anyone to explain why knives should be drawn. What is clear, the prosecution say, is that Jeffrey Okafor was the man who killed him."
The prosecution said four days later Okafor boarded a flight from Heathrow Airport to Lagos using his brother's passport.
He was extradited from Nigeria in November last year.
Okafor pled not guilty to the murder but the jury took just two hours to convict him in London yesterday - six years after Mr Beatson-Asiedu's death.
Judge Christopher Kinch QC will sentence him today.
