Five women have died violently in Ireland so far this year, with four killed in their own home.
A new report from Women's Aid also reveals that 56% of women were killed by a current or former boyfriend, husband or partner.
Strangers make up just 13% of perpetrators of female homicide in Ireland.
230 women have been violently killed in Ireland since 1996 and 16 children have died alongside their mothers over the past 23 years.
Women's Aid says almost 90% of women are killed by a man known to them.
The organisation is calling on the government to introduce, properly resource and legislate for formal Domestic Homicide Reviews and increase supports for bereaved families.
