A convicted murderer in jail in England is to be called to give evidence at the inquest into the death of a Co Tyrone teenager he was acquitted of murdering, a coroner ruled today.

Robert Lesarian Howard, from Wolfhill, Co Laois, was sentenced to life in prison in Britain in 2003 for murder of a 15-year-old English schoolgirl, Hannah Williams.

A 61-year-old man accused of murdering a schoolgirl who vanished more than 10 years ago went on trial yesterday.
