Sean Hackett
Sean Hackett has been found not guilty of murdering his father, but guilty of manslaughter.
The 19-year-old admitted shooting his father, but his lawyers argued that he was mentally ill at the time of the shooting.
They argued that Hackett had committed manslaughter on the grounds of diminished responsibility.
Aloysius Hackett (60) was shot twice in the head by the former Tyrone GAA minors star in Augher in January, 2013.
