The trial of a 17-year-old, charged with the murder of another youth in Co Mayo in 2015 has heard the victim was chased around the back garden of a house before he was fatally stabbed.
Dovydas Jenkas died from a single stab wound on the morning of 19 December 2015. The attack took place at a house in the Claremont Manor estate in Claremorris.
The teenager, who cannot be named due to his age, is on trial at the Central Criminal Court, sitting in Castlebar.
The jury heard Mr Jenkas had been visiting the accused's sister in the house, when her brother knocked on a locked bedroom door demanding to know who was with her.
Mr Jenkas fled from the house through a bathroom window.
The accused denies the charge and told Gardaí what had happened was accidental.
He added that he chased his victim around a trampoline in the garden, shouting at him to leave but he would not do so.
The accused told officers he had a knife in his hand which he had taken from his room and accidentally stabbed his victim.
The court the victim then "started roaring and stumbling and fell to the ground".
State Pathologist Professor Marie Cassidy gave evidence that the cause of death was a single stab wound on the left side of the chest which penetrated the rib cage into the anterior wall of the heart.
Blood loss was considerable, the pathologist said.
Mr Jenkas, who was a fifth year student at St Colman's College, Claremorris, died at the scene despite intensive efforts by paramedics and others to save him.
The trial, before Mr Justice Butler and a jury eight women and four men, is expect to continue until next week.
