The grieving family and girlfriend of murdered University of Greenwich student Samuel Guidera have made a fresh appeal for information on the two year anniversary of his death.
Despite four arrests and a £20,000 reward for information leading to prosecution of the person responsible, his murder remains unsolved.
On Saturday 12 February 2011, Samuel was found collapsed in the street at Bailey Place, near Penge East station.
He was taken by ambulance to hospital and was later pronounced dead. His wallet had been taken from him in the attack.
A post-mortem examination gave cause of death as a single stab wound to the heart. On the anniversary of his death, his girlfriend Claire said she was proud to have known him.

Two years on, I want to know what gave these people the right to end Sam's life like that. His desperate attempt to call 999 before he lost consciousness, the panic he must have felt when he realised what was happening, the loneliness of dying in the street; these things will haunt me forever, but Sam actually went through them.
"Sam was studying History and Politics and would have been an amazing teacher. He never felt that he was better than anyone else; he was friends with people from every walk of life. Everyone who knew Samuel is so proud to have known him."
