A judge on Thursday acquitted the only man charged with murder over the 1998 Omagh bombing, which killed 29 people, making it Northern Ireland's deadliest terror attack.
Judge Reginald Weir, who heard the case without a jury, ruled that Sean Hoey was not the bomb-maker behind the attack, which killed mainly women and children.
Hoey, 38, faced more than 50 charges over the attack, which was carried out by dissident Irish Republican Army group, the Real IRA, on Aug. 15, 1998.
During the 56-day trial, prosecutors tried to tie Hoey to the Omagh bombing and other explosions using DNA evidence. His lawyers challenged the evidence, claiming it was unreliable.
