Parents of murdered Sam Guidera appear on Crimewatch
Detectives appeared on Crimewatch alongside the parents of a murdered 24-year-old student in a bid to find "crucial" witnesses.
Officers said there was a “good response” following the broadcast on Monday night about the fatal stabbing of Sam Guidera at Penge East station on February 12.
It was revealed for the first time that history and politics student Mr Guidera had his wallet stolen during the attack, in Newlands Park.
He was stabbed once in the heart and found collapsed at around 9.55pm. Police are desperately seeking anyone who travelled on the Victoria to Orpington train which would have pulled in to Penge East at around 9.41pm.
Appearing on the show, Detective Chief Inspector Laurence Smith said: “We’ve had a good response but we need everybody who was on that train that arrived at Penge East station at 9.41pm to contact police.
“They left that station moments before Sam was fatally stabbed in the heart. We need these people, it’s crucial they contact police now.”
The student’s parents Sarah and Chris appeared on the show.
Mr Guidera, 53, a Royal Mail manager, warned that his son’s killer could strike again. He said: “The people who have done this are cowards and if they can do it once, they will do it again. We would not want anybody to go through what we are going through now. We have a life-sentence because we will not see Sam again. We are in bits.”
Speaking about his son, he added: “He was a lovely boy, funny, kind, intelligent. His life has been swept away needlessly.
“We were just one of those close families living their lives, bringing up children and enjoying ourselves. This has destroyed us.”
Friend Tyrus Gordon-Young paid tribute to him, saying: “Sam was such a nice guy. He always had a smile on his face.
“He was always talking about music and football. I don’t understand why anyone would want to hurt him, he was such a lovely person.”
Two men, aged 18 and 39, have been arrested and bailed to return to a south London police station in April.
