LATEST: An inquest into the death of the fiancee of BBC children's presenter MARK SPEIGHT has found her death"non-suspicious". Actress Natasha Collins, 32, was found dead in the bath of the north London home they shared last week (03Jan08). A post-mortem examination failed to reveal the exact cause of death but a hearing at Westminster Coroner's Court in London concluded Collins was not murdered. Speight was originally arrested on suspicion of murder and supplying cocaine and was released on bail. But the findings, which are subject to further investigation, appear to show the incident was a tragic accident and could eventually clear the star of causing his lover's death. A spokesman for the Metropolitan Police insisted there is still more work to be done. Detective Inspector Simon Whittaker says, "Clearly the cause of death is unascertained and subject to further investigation."
