THREE men who stabbed a property developer to death while trying to rob him of drugs have been jailed for a total of 35 years.
Afyon Saint-Hilaire, 22, was ambushed and knifed in the leg in his car after arranging a meeting to sell £450 of skunk cannabis.
He managed to get back in his Mercedes and drive away before crashing into a parked car and collapsing from loss of blood near the scene in Downham, south London.
Shyheim Green, 20, from South Croydon, Lance Sloley, 23, from Thornton Heath and Jordache Smith-Challis, 20, of Brighton, were all convicted of manslaughter and conspiracy to rob by an Old Bailey jury. They were cleared of murder.
Sloley and Green were both jailed for 12 years and Smith-Challis was jailed for 11 years for manslaughter.
Mr St Hilaire's cousin Mickyle Bromfield, 24, was convicted of possessing a firearm with intent to endanger life and jailed for 10 years.
Sentencing Smith-Challis, Green and Sloley, Judge Gerald Gordon said: "In my judgement they [the jury] were satisfied that the three of you arranged what appeared to be a genuine drugs deal.
"At some stage [this] involved for the three of you a plan not just to deal drugs but to rob the deceased.
"While the precise timing of the start of the plan to rob is unclear, I am satisfied that it was not at the last minute nor on the spur of the moment.
"That would have firstly been far too dangerous.
"At least one of you took a knife to the scene, doubtless for the purpose of using it should that need arrive, in pursuance of the robbery in a way that risked harm as it was bound to.
"The other two knew of the presence of that knife, and knew it might be used in that way with the potential consequence.
"Bearing in mind the small value of the transaction it may be that the real motive for the three of you has still not been revealed.
"It matters not. Whatever the real motive you fall to be sentenced for what you planned.
"This was knife crime leading directly to the loss of yet another young life, with all the consequential devastation - in particular for his family, his parents, his siblings and his child.
"The crime or crimes were committed in pursuance of, at the very least, drug crime and robbery, and was committed by a group of you in a public street where ordinary, decent people were like to be and were indeed present.
"Those who use weapons such as knifes in pursuance of drug crime must expect very long sentences."
It remains unknown who carried out the stabbing.
Smith-Challis - who earned the nickname 'Gruesome' as an amateur boxer - admitted having a fight with Mr Saint-Hilaire on the night of his murder but insisted he had nothing to do with the stabbing.
He claimed the first he heard about the victim's death was on the news the next day.
Two other suspects, Marcus El-Alfy, 18, and Vishal Deowram, 18, were earlier cleared of all charges.
El-Alfy, of Riverside Court, Vincent Close, Bromley; Deowram, of Wharfedale Gardens, Thornton Heath, south London; Smith-Challis, of Bexhill Road, Brighton; Green, of Joshua Close, South Croydon and Sloley, of Broughton Road, Thornton Heath, all denied murder and conspiracy to rob.
Sloley and Green were both sentenced to 12 years imprisonment for manslaughter, and concurrent sentences of eight years for conspiracy to rob.
Smith-Challis was jailed for 11 years for manslaughter, with a concurrent sentence of seven years for conspiracy to rob.
Bromfield, of Field Lane, Brentford, Middlesex, denied possessing a firearm with intent to endanger life and an alternative of possessing a firearm with intent to cause fear or violence and was sentenced to 10 years imprisonment.
