A 34-year-old man who killed a three-and-a-half-month-old baby lied to medical staff, gardaí and the child's mother, the Central Criminal Court has heard.

Philip Doyle from Tinakilly, Aughrim, Co Wicklow, was convicted of the manslaughter of Ross Murphy at a house in Gorey in Wexford on 5 April 2005.

Mr Doyle claimed the baby fell from his arms after his mother went out to get a DVD, but the court heard Ross died from brain trauma and had injuries consistent with having been shaken.

In a victim impact statement read to the court, the baby's aunt Edele said his death was every mother’s nightmare.

She said the family were heartbroken and left with an empty place in their hearts that can never be filled.

She said their memories of Ross are overshadowed by what he went through, not knowing how painful and tragic his last days were.

In a letter of apology read to the court, Doyle said he was sorry for lying and wished he had done things differently.

He said he will regret what he has done for the rest of his life.

Mr Justice Patrick McCarthy said he will consider the submissions and impose sentence next Tuesday.
