A vigil is to be held on Wednesday evening for an eight-year-old girl and her 39-year-old mother who are understood to be victims of a double murder in Ballymena, County Antrim.
They were found dead at a house on the Cullybackey Road on Monday where the body of a 41-year-old man – understood to be a male relative – was also discovered.
The case is being treated as a suspected double murder and suicide.
The family was originally from Poland, although it is understood the child was born in Northern Ireland.
The vigil will be held at the Braid Arts Centre at 18:30 BST.
Sonya McMullan from Women’s Aid told News NI she was “absolutely devastated” when she heard about the deaths.
“Yet another family is experiencing such grief and loss that no family should ever have to go through,” she told News NI.
Women’s Aid has kept track of the number of women and girls who have been killed in Northern Ireland since 2020 and McMullan said this case brings that toll to 31.
“We contribute to the femicide record across the whole of the UK, but it’s devastating having to keep that record and it’s so very important that we remember each and every one of them.”
McMullan said political leaders, the media and members of the public all have a part to play in stopping violence against women and girls.
“This is a call to action that every one of us needs to do more,” she added.
