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.
