Knife Killer Starting 12-Year Sentence

A knifeman, who killed a rival who jumped out of a car and chased him along a south London street, has been locked-up for twelve years.

Rio Julienne-Clarke, 21, was convicted of the manslaughter of Dwayne Simpson, 20, of Stockwell.

On Tuesday, February 25, last year, police were called by the London Ambulance Service (LAS) at around 5.00pm to a man stabbed in the chest in St John's Crescent, Stockwell.

The victim, Simpson, was taken by the LAS to a south London hospital in a critical condition.

He was later pronounced dead on February 27.

The Old Bailey heard Simpson was in long running dispute with Julienne-Clark.

They got into a fight after Simpson saw Julienne-Clark chasing a friend in Brixton Road.

Simpson was driving past and got out the vehicle he was in and gave chase.

Simpson caught up with Julienne-Clark and a fight ensued.

He was then fatally stabbed.

A post-mortem examination gave cause of death as stab wound to the heart.

Officers arrested Julienne-Clark in April after he continually tried to evade police.

They went to an address in Clapham and forced entry into a premises where he was staying.

He tried to escape but he was detained by officers.


Detective Inspector Nathan Eason said: "Dwayne senseless killing has caused immense suffering to his family and friends.

“This has been a difficult and complex investigation and officers wish to pass on their gratitude to those members of the community that provided assistance.
