Detectives investigating the Valentine's Day murder of Billy Cox have released a new image of the teenager, and two suspects, on the 12th anniversary of his death.
The 15 year old was shot in his bedroom in Clapham in 2007. His family hope the new cctv picture will lead to an arrest.
Billy had left Acre Lane in Brixton on 14 February 2007 at about 14.30hrs and made his way home to Fenwick Place in Clapham.
Billy’s sister, who was aged just 13 at the time, returned home and found her brother heavily bleeding, lying on his bedroom floor. There were no signs of forced entry to their home making it possible that Billy knew his killer.
Emergency life support was given to him at the scene, but despite the best efforts of the paramedics, Billy was tragically pronounced dead. A post-mortem examination gave the cause of death as a gunshot wound to the chest.
The investigating team have now released a still CCTV image taken at 14.55hrs on 14 February 2007 on Landor Road in Clapham, of two males walking with Billy into Fenwick Place, close to the time of the murder. Police believe they know the identity of the male in the middle, but the second male - furthest from the road - remains unidentified.
Officers are urging the second male to come forward to assist them with their enquiries. He may hold vital information that may assist officers in bringing justice to the Cox family.
The male is described as being light-skinned and was wearing a dark coloured top, dark coloured trousers with a white stripe down the side and white trainers. He was carrying a distinctive white shoulder bag.
A £20,000 reward is on offer for information leading to the identification, arrest and prosecution of the person(s) responsible for the death of Billy Cox.
