A woman told a jury she believed from what her brother-in-law said days after the incident that he meant to kill her husband when he struck him with his truck.
Ms Jacinta Malone claimed he told her that it was she he loved and not her sister. She claimed he said also that the death of her husband had occurred "for all the wrong reasons" and asked her if she understood what he meant.
Replying to Judge Kieran O'Connor, who asked what she understood by this comment, Ms Malone said she took it to mean he meant to kill her husband.
Later she denied in cross-examination by Mr Peter Charleton SC, defending, that she urged her brother-in-law to continue driving his truck after it had just run into her husband.
She agreed with Mr Charleton at Dublin Circuit Court that she cried "Go on, go on" after she heard a loud bang.
She told him she did not know it was the sound of the truck hitting her husband. She thought it was her husband throwing rocks at the truck in which she was travelling with her brother-in-law and her children.
She was continuing her evidence in the trial of her brother-in-law, Mr Steven Graysmark (41), of Sundale Avenue, Tallaght, who has denied the unlawful killing of her husband, Mr James Malone (32), on Fonthill Road South on August 29th, 1999.
She told Mr Charleton she had not seen her husband before the truck hit him. She said her brother-in-law appeared "upset" after the incident.
She agreed with Mr Charleton that her husband suspected she was having an affair with Mr Graysmark.
She also agreed this was totally unjustified, especially considering she had been completely devoted to him despite his violent behaviour towards her throughout the marriage.
Ms Malone agreed with Mr Charleton that her husband had a "Jekyll and Hyde" personality and this had caused a rift between her and the rest of her family. He had also once hit her mother and sister, and had taken a hot iron to her brother's face.
The case continues.
