Gardai do not believe that three children tragically found dead in Dublin last night died of natural causes.
A horror scene was sealed off after the shock discovery of the kids in the home in Newcastle in the south-west of the county.
A woman was also rushed to hospital after being found in a disorientated state by a taxi driver on the street outside at around 7pm.
After finding the woman, gardai then went into the home at Parsons Court were the grim discovery was made.
It’s understood a note was also found at the scene.
The area at the quiet village estate was sealed off as the Garda Technical Bureau and forensics team moved in.
The kids, two boys and a girl, have been named as Conor (aged 9), Darragh (7) and Carla (3) McGinley.
It is understood that the children did not die of natural causes.
However investigators must wait for post-mortem examination results to determine the course of the investigation.
Meanwhile, a garda spokeswoman appealed to anyone with information to contact Clondalkin Gardai Station.
She said: “Gardaí are currently attending the scene of an incident at a domestic house in Newcastle, Co. Dublin. The bodies of three children, two boys and a girl, have been discovered.
“Gardaí are currently investigating the circumstances of their unexplained deaths.
“A female in her 40s has been taken to Tallaght Hospital.
“Anyone with any information in relation to this incident is asked to contact Clondalkin Garda Station on 01 666 7600 where an incident room has been established.”
There was an eerie sense of horror and disbelief as local people heard of the sudden deaths of three young children.
A number of relatives of the family arrived at the grisly scene and looked distraught and ashen-faced as they spoke to detectives.
One neighbour who did not want to be identified said: “I only found out five minutes ago after my brother rang because it was on the news.
“I was oblivious [because we live in the corner] so I didn’t know anything. “
Another neighbour had visited the woman and said they were “trying to piece it together ourselves”.
She added: “I have kids upstairs, she has kids next door.
“I was actually was worried because she has three kids as well and I didn’t know who it was.
“It doesn’t seem real. I’ll be honest we’re shaking.
“I don’t know anything yet and it hasn’t sunk in because I didn’t know about it the last two hours.”
The two friends said the family moved into the estate about a year ago.
The second local woman said: “I don’t think we’d know them to see them because our children are younger as well.
“It’s a quiet estate.
“I think it’s an understatement to say we’re shocked.
“I’m sure more details will emerge in the morning but I think tonight everybody is just like…I can’t believe it’s in our doorstep.”
