The grieving family of Samuel Guidera are making a fresh appeal for information on the second anniversary of his death. The 24-year-old student from the University of Greenwich was stabbed to death in February 2011.
The girlfriend of a murdered student has recalled how she rang his mobile phone and a police officer told her he'd been stabbed. Claire Smith was waiting to meet Samuel Guidera on the night he was attacked near Penge East Station in South-East London.
That was two years ago, and despite a £20,000 reward being offered for information, his murder remains unsolved. Claire has spoken publicly for the first time, as she joined a new appeal to catch Samuel's killer. Ronke Phillips reports.
Police have released CCTV footage of people who were in the area on the night that Samuel died.
They are still trying to identify around 32 people who can be seen in the footage - which was taken in and around the shops outside Penge East Station between 21:40 and 22:00 on Saturday 12 February 2011.
Detective Chief Inspector Chris Jones from the Metropolitan Police said that the force was offering a £20,000 reward for information leading to a conviction.
"Whilst two years have past since the murder of Samuel Guidera, the MPS remains committed to identifying and bringing to justice those responsible. I am convinced there are persons within the community who for reasons, be it family or other loyalties, have yet to come forward with the information they have.
"I would ask them to consider the devastating impact Samuel's death continues to have on his family and loved ones and appeal for them to contact the investigation team. The MPS continues to offer a £20,000 reward and I would stress any person coming forward will be spoken to in confidence with all measures to protect their identity and safety considered."
Samuel's parents, Sarah and Chris Guidera, said that his death had given them a life sentence.
"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.....
"Time is not a healer, we will never get back to normal; the people we were before no longer exist. So please look at your son, brother, uncle, think how you would miss them and if you know anything come forward; don't let the cowards who took my son's life kill again."
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."
