The three men and one woman responsible for the death of teenager Jermaine Goupall have been jailed.

Jermaine Goupall was 15-years-old, standing outside a Costcutter in Green Lane, when a group of people wearing balaclavas and armed with knives and machetes pulled up and chased him down.

Most of the group of people Jermaine was with took cover in the shop, but the teenager was chased on foot with the car following, until he was caught and stabbed. Despite the best efforts of bystanders and emergency services, Jermain bled to death.

Yesterday (February 14), Adam Benzahi, 21, of Carshalton, Samuel Oliver-Rowland, 18, of Epsom Road, Waddon and Junior Simpson, 17, of North Downs Crescent, New Addington were all found guilty of murder, while Saskia Haye-Elliot, 18, North Downs Crescent was found guilty of manslaughter.

Today all four were sent to prison - three of them were given life sentences.

DCI Tony Lynes, who led the investigation, said: "I can only imagine the fear Jermaine felt as he was attacked.

"Members of the public rushed to his aid as they tried to stem the bleeding and keep Jermaine calm before the emergency services arrived and continued to administer first aid, but tragically he died from his injuries.

"These four defendants denied involvement, but the weight of evidence against them was enough to convince a jury of their guilt.

"Jermaine's senseless murder appears to have stemmed from gang rivalry and violence, and we now have a family left utterly devastated and the lives of all involved blighted forever."

The sentences handed down were:

Benzahi - life imprisonment and will serve a minimum term of 22 years

Oliver-Rowland - life imprisonment with a minimum term of 20 years

Simpson - life imprisonment with a minimum term of 18 years.

Haye-Elliot - 12 years and six months imprisonment
