FILE - A March 25, 2009 photo from files showing former Sinn Fein councillor Brendan McConville at Lisburn Magistrates Court. Two Irish Republican Army dissidents were found guilty Friday, March 30, 2012 of the 3-year-old murder of a Northern Ireland policeman because of crucial testimony from a mystery witness. Constable Stephen Carroll, 48, was shot through the back of the head as he sat in his patrol car in February 2009. The Continuity IRA splinter group claimed responsibility for the first killing of a Northern Ireland police officer since 1998, the year of Northern Ireland's Good Friday peace accord. Brendan McConville, 40, and John Paul Wootton, 20, were both found guilty after a two-month trial based on a wide range of evidence including British Army surveillance, DNA and forensic clues and key witness evidence. Belfast High Court Justice Paul Girvan said prosecutors proved that both men were "intimately involved" in shooting Carroll. He postponed sentencing to a later date.
