New appeal to find killers of Greenwich student
Two years after Samuel Guidera was murdered his family have made an emotional appeal for information to help find his killers.
The University of Greenwich history and politics student was found collapsed in the street near Penge East Station at about 10pm on February 12, 2011. He died about an hour later.
A post-mortem examination gave the cause of death as a stab wound to the heart. His wallet had been taken in the attack.
Samuel, 24, had been watching football on television with friends before travelling by train from Bickley to Penge East.
He crossed a footbridge over the railway to the Newlands Park exit where he was killed.
CCTV showed Samuel as he went into a convenience store minutes before he was killed.
Since the 2011 attack a £20,000 reward has been offered and four arrests have been made, but no-one has yet been charged.
Samuel's parents and girlfriend made appeals for new information.
His mother and father, Sarah and Chris Guidera, said: "We still feel a sense of anger and all we can do is continue to cope with each day as it comes, with the help of medication, family, friends, whatever it takes.
"As parents we have seen the devastation and heartbreak it has caused Sam's brother and sister, other family members and friends. We just want somebody out there who knows something that could help in the apprehending of the killers to come forward so they do not have the opportunity to take another person's life and destroy another family.
"It could be somebody reading this who gets the call about the savage death of a loved one next."
Samuel's girlfriend, Claire Smith, said: "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 without a single person who knew his name; these things will haunt me forever, but Sam actually went through them. And for what?"
