Students of Ashling Murphy have been laying flowers outside the school where she taught in Tullamore, Co. Offaly.
The 23 year old primary school teacher was killed while out for a run along the canal at around 4pm yesterday afternoon.
She's being remembered as "kind", popular and exceptionally talented" by those who knew her.
A 40 year old man is still being questioned by Gardai in connection with the random attack.
Principal of Durrow National School, James Hogan, says students have been sharing their memories of Ashling today:
There's a sense of shock and sadness in Tullamore in the wake of Ashling Murphy's murder:
Ashling was actively involved in the traditional music scene - and played a number of festivals across the country.
Eddie Murphy, head of the Comhaltas National Folk Orchestra, has been paying tribute:
There are calls for curriculum changes to be introduced to change the culture of violence against women.
The Women’s Council of Ireland says that as well as policy and legislative changes, conversations need to had throughout society.
Director of the group, Orla O’Connor, told Shannonside Northern Sound that younger age groups need to be targeted to end these attacks.
