The family of a two-year old boy found dead in an apartment on Saturday, have described as "vile" and "disgusting", messages posted online about the family, hours after the boy's lifeless body was discovered.
A post mortem is been carried out at University Hospital Limerick on the body of little Robert Kelly who was found unresponsive by his uncle Damien, 20, when he went to wake him from an afternoon nap.
The post mortem is due to finish at around 6pm this evening.
The child's grand uncle, Derek Kelly, said the family are still trying to come to terms with Robert's sudden passing, and he condemned abuse he said had been thrown at the family across social media websites.
"We're very irate," Mr Kelly explained.
"They were calling the family scumbags. One woman (who) put it up realised what she had done, and she took it back down again."
"There was some vile and disgusting comments on Facebook initially. As far as I know they have (been taken down)," he added.
Mr Kelly said the boy would be "waked" from the Kelly home in O'Malley Park from between 4pm-8pm tomorrow. Mass of the Angels is to take place at Southill Church at 11am.
Little Robert is due to be buried alongside his grand uncles Michael and Damien.
Michael was known as a 'hard man' enforcer in the 1980s, later turning his back on crime to become a poll-topping local politician.
He is believed to have shot himself while staying at his mother's house in June 2004. However, the gun was never recovered.
His body was later exhumed by the family to disprove a newspaper story that the gun was later buried along side him in his grave.
"Damien was hanged in Cork in Fort Mitchell on Spike Island in 1994," Derek Kelly said.
"He was hanged by three prisoners there. Mickey was shot dead in Lilac Court in 2004. (Robert) is being interred with them. We didn't want him on his own, we wanted his grand uncles to look after him in the grave."
He said while he did not know the exact cause of his grand nephew's death, he understood it may have been caused by sudden infant death syndrome or cot death.
"Sudden infant death is the line we seem to be getting back, but that's not confirmed," Mr Kelly said.
A Garda source confirmed they were not treating the death as suspicious.
Gardaí stated they would not officially comment until the results of the post mortem were known.
