"He was a good little boy who never made any trouble," said a mother living in the south Dublin housing estate where a six-year-old boy named Faizan and his sister and mother died.
"My son played with the little boy a few times. We can't believe this tragedy has happened," said the woman at her home in Llewellyn Court in Ballinteer.
Nearby crime-scene tape swayed in the breeze outside the house where the bodies of Faizan, his sister Asfira (11) and their mother Seema Banu (37) were discovered by gardaí last week.
"He was a very quiet child. I never heard him speak," said the 33-year-old mother of two.
"We saw the police outside the house and thought it was a burglary. We couldn't believe it when we heard the news," she said.
"Our son is only seven years old and we didn't know how to explain what happened the family. We've told our son the family went to hospital with Covid-19," she said.
"There won't be any Halloween here. The joy is gone," she added.
The three victims had moved from Bangalore in India to their new Irish home last February and they were not well known in the community.
Bunches of flowers were piled at the base of a tree outside the house of tragedy. One of the bouquets was from the Indian ambassador to Ireland. Sadness linked Ballinteer with Bangalore.
A neighbour in her 60s said she felt a deep sadness for the family and friends of the victims.
"My hearts go out to their loved ones who are so far away," she said.
