Vigils were held in both countries as tributes poured in for the 24-year-old when the discovery of her body brought a four-day search to an end.
After Pacteau appeared in court charged with murder, around 300 people gathered in Glasgow’s George Square for a memorial organised to show support for her family.
Strangers spoke about how they were moved to attend the vigil to show their support, many bringing flowers and candles. Cards and messages were left, with people expressing their grief.
Her parents and two of her brothers arrived towards the end of the vigil to look at the floral tributes. A piper played and others sang Scottish and Irish songs before a minute’s silence was held.
The following evening, 1,000 candles were lit as neighbours gathered to be part of a silent vigil, close to where the student lived.
In Ireland, the University of Limerick held a Mass in her memory and created a small memorial with a photograph and candle at the reception to the building where Ms Buckley’s nursing studies began.
Prayers were offered at services near the family home in Mourneabbey, north Cork, and the nearby town of Mallow.
The outpouring of support for the family also raised £50,000 in an online drive organised by her former university classmates — more than 10 times the original target amount.
