Desperate appeal for informant in Sam Guidera Penge murder
Police are desperate to speak to a key informant who contacted them following the murder of a student.
The man called the anonymous Crimestoppers telephone line on March 1, the day after a BBC Crimewatch programme was broadcast appealing for information about the fatal stabbing of Sam Guidera at Penge East Station.
Police believe Mr Guidera, 24, was murdered in a botched robbery as he returned home from Bickley after spending the day with friends watching football on February 12.
Det Chief Insp Laurence Smith, leading the investigation, said: “We would very much like to speak to this person again and would urge them to contact us.
“We believe that this man may hold information that is very important to this investigation and may enable us to find Samuel’s killer.
“I would ask this person to consider contacting us direct. We can protect their anonymity but we do need people to come forward with information.”
Police are offering up to £20,000 as a reward for information leading to the identification, arrest and prosecution of the killer.
They have also released a YouTube video showing CCTV footage of commuters who were at the station at the time of the attack, 9.55pm.
About 20 of a possible 40 have contacted police but officers say it is vital to speak to the rest.
Mr Smith added: “Even if these people think they have no useful information for us, we want to speak to them. They may hold information that helps us piece together the events leading up to Sam’s death.
“If you think you recognise any of these people, you can help us trace them. I urge you to call us and help find some justice for Samuel and his family.”
