Most Popular BBC He's spent almost 20 years in prison for murder - but could new evidence give Omar an alibi? Despite spending almost 20 years in jail, Omar Benguit has always said he's not guilty of murder. Could new evidence provide him with an alibi? Bronagh Munro From the moment he was arrested in August 2002 in connection with a young woman’s murder, Omar Benguit has protested his innocence. At first glance, the case against him looked cut and dried. A large number of witnesses testified against him. Omar was a drug addict with 60 criminal convictions, including one for stabbing another man. At his trial, the main prosecution witness told the jury she’d driven him, covered in blood, to a crack house, after the murder of South Korean student Jong-Ok Shin, known as Oki. Omar was said to have stabbed her as she walked home alone on a Bournemouth street, after she refused to come to a party with him.
