Tory, 17, a pupil at Loreto Convent secondary school, died after a night out with pals almost a year ago.
Fifth year student Tory had collapsed at Voodoo Nightclub on the morning of July 15th last.
Tory, from Bomany, was taken by ambulance to Letterkenny University Hospital where she later died at 6:30am.
A Garda statement issued today says investigations to date have not determined the cause of Tory’s death.
Gardai have thanked all those who came forward and assisted during the course of the investigation.
However it is believed other people who attended Voodoo Nightclub on the morning of Tory’s death have yet to come forward to assist with this investigation.
“Anybody who has information which my assist and explain why Tory died is asked to come forward by contacting the Incident Room at Letterkenny Garda Station on 074 9167100 or if they wish to remain anonymous they can call the Garda Confidential Telephone line on 1800 666 111.
“Any assistance will be greatly appreciated and callers will be dealt with in the strictest of confidence,” said a spokesman.Tags:
