A Co Leitrim teenager has been sentenced to six years for killing a 73-year-old man two years ago.

Brendan McGovern, 19, from Killahurk, Carrigallen, was found not guilty of murder, but convicted of the manslaughter of John Golden at his home in Killeshandra, Co Cavan.

Mr Justice Paul Carney said he was suspending two thirds of the sentence because of the teenager's previous good character, his strong work ethic and offer of a plea.

McGovern had claimed that Mr Golden had sexually abused him when he was 13 or 14 years old and that he cut down his working hours at a local petrol station to avoid him.

He said he was in a pub on 6 September 2010 when the pensioner smiled in the window at him.

The teenager went to Mr Golden’s home to confront him or, as he put it, to "give him a slap" because of his continued taunts.

However, he said Mr Golden provoked him by presuming he had come for sex. McGovern said he lost control and attacked him.

Mr Golden died in hospital a month later.

Mr Golden was investigated by gardaí during the 1990s when he admitted showing pornographic videos to teenage boys and statements were read from two other young men about his activities.

The court heard that McGovern was an honest, reliable, extremely hard-working, remorseful and very shy young man who had intellectual difficulties.

Mr Golden had no family so there was no victim impact statement.

Mr Justice Carney said it was unusual there was no one to speak to the memory of the deceased, but that the gravity of the crime must not be diminished.
