A mother of three and a 19-year-old have been cleared of murdering a man at a Christmas party in Drogheda, after the State's case against them collapsed when the trial judge ruled there was insufficient evidence to convict them.

An eye-witness in the case of a man and woman on trial for murdering a 29-year-old man in December 2007, has told the jury he saw a woman jumping on the victim's stomach as he lay unconscious on the ground.
