A US woman whose abusive father was shot to death by her mother has said she was relieved when he died.
Barbara Sheehan shot her husband Raymond Sheehan 11 times as he shaved on the morning of February 18, 2008 after enduring years of violence and threats.
"He was such a monster in all of our lives," her 26-year-old daughter Jennifer Joyce said in an interview this week with the US ABC Network.
"I was always so afraid that he was going to kill my mum. It's such a relief that he's gone.
Ms Sheehan has written about her father's death and her mother's murder trial in the recently published book In Bed with the Badge: The Barbara Sheehan Story.
At her mother's 2011 trial for second-degree murder and two gun possession charges Ms Sheehan and her brother Raymond, 22, testified against their father.
She said her mother "would never hurt anybody" and had killed her husband, a former New York police officer, because she genuinely feared for her life and the rest of her family.
Barbara Sheehan was acquitted of the murder and one weapons charge but still faces the possibility of jail for the second gun charge.
Ms Sheehan said the most difficult part of the trial was hearing the "lies" her father's side of the family told to protect his reputation.
She said she felt helpless as her dad's family argued that there was nothing wrong with him.
"You just want to say, 'No, you're wrong. That's not the story.' But you can't really do anything."
While the death of her father and her mother's murder trial were emotionally draining Ms Sheehan said the ordeal had brought the pair closer together.
