A WOMAN accused of murdering her husband by stabbing him to death had a background of schizoaffective disorder.

Tanya Doyle (40) of Pairc Gleann Trasna, Aylesbury, Tallaght, has pleaded not guilty to murdering Paul Byrne (48) at that address on September 4, 2009.

Defence Counsel Mr Brendan Grehan told the jury at the Central Criminal Court that the issue in the trial would be Ms Doyle's mental state at the time she carried out the killing.

Consultant psychiatrist Professor Patricia Casey told Mr Grehan that Ms Doyle presented at the Mater Hospital on September 1, 2009, alleging she had been assaulted the previous Thursday.

Prof Casey read medical notes to the court from her registrar, Dr Kershee Naidoo, saying Ms Doyle reported she had enemies in Dublin and was asking for blood tests, an eye check and a smear check.

Ms Doyle had told medical staff she was interviewed by a newspaper and the article referred to her as a high-class madame.

She said she left Dublin when her name appeared in the newspaper and went to Portugal and Africa before going to visit a friend in Belfast but had to return because she ran out of money.

She was described as manic with psychosis and Prof Casey told the jury when someone is manic they are overactive and have beliefs that are untrue and unshakeable.

A toxicology screening of Ms Doyle tested positive for angel dust, which was sold in head shops in Dublin at that time, Prof Casey told the court.

The court was also told she was on anti-psychotic and anti-depressant medication but said she had not been taking one of the drugs for three weeks.


Prof Casey also told the court Ms Doyle had previously been under psychiatric care in Tallaght.

Deputy State Pathologist Dr Michael Curtis told the court the cause of death was multiple stab wounds.

He said Mr Byrne had sustained in excess of 60 stab wounds, including defensive wounds.

In cross-examination, Dr Curtis agreed with Mr Grehan that it would be fair to use the term "overkill".

The jury heard earlier that Ms Doyle had previously stabbed the engineer twice on one occasion in 2006 but there had been no prosecution in relation to that.

The trial continues.
