More than 600 people attended a vigil in Banbridge on Thursday evening.
Banners bearing the names of 25 women killed in Northern Ireland since 2020 were held up.
There were also candles, speeches and a minute’s silence.
Among those who spoke at the event was Noel McNally, whose pregnant daughter Natalie was murdered in Lurgan in December 2022.
Eileen Murphy, chief executive of Women’s Aid Down/Armagh, said the vigil had been organised in response to the local community.
“Our vigil tonight is for all the women who have been murdered this year – seven of them to date and the year’s not over yet,” she said.
She said the large turnout was a “tribute to Karen and her memory that her community, her local community, felt so strongly about her murder”.
“Normally we don’t get as many people turning up to our vigils at all – there was a huge turnout tonight,” she said.
