British woman who killed partner acquitted of murder

From The BBC, June 3, 2008

Christine McGreavey, 44, was charged with the murder of Barry Parkin, 48, during a row at their home in Manorbier Crescent in Walton, Liverpool. Ms McGreavy, who has a four-year-old daughter with Mr Parkin, said the death happened accidentally during a row after she found out he was gay. She was also found not guilty of manslaughter at Liverpool Crown Court.
The couple were arguing at their home in January.

Ms McGreavey told the court that the blow, from which Mr Parkin died five hours later, had occurred accidentally. He came out of the kitchen during the row with a knife pointing towards his chest. She went forward to disarm him and accidentally bumped into him and the knife went into his chest. It was alleged she told police that she hoped he died.
She later apologised and said she had just "flipped" as she had just found out he was gay.
