Mum-of-three describes seeing partner shot to death

A mum-of-three has described to a murder trial how her partner was shot to death at the front door of their home by a "young boy" in dark clothes.

Michelle Usher told prosecuting counsel Shane Costelloe SC that she thought it was a joke until she heard a third shot and her partner, 35-year-old Alan O'Neill, screamed out in pain.
