The body of Julianne Williams, a former pupil at Devenish College, was found at a house in the Irvine's Crescent area of the town. It's understood the Northern Ireland Ambulance Service alerted the PSNI who then sealed off the area, close to Chanterhill, in order to carry out forensic investigations.
The cause of Ms. Williams' death has so far been 'undetermined', though a police spokesperson has told this newspaper that a post-mortem examination carried out yesterday (Wednesday) has found there was nothing suspicious about the way in which she died.
The PSNI say enquiries into her death are continuing.
It is believed Ms. Williams was hoping to pursue a career in health and social care, through Ruthledge Recruitment and Training in Enniskillen.
Ulster Unionist Councillor Raymond Farrell described her death as a "tragedy".
"The sudden death of Julianne is an awful shock to all who knew her. Here we have a young girl in the prime of life with so much potential and so much to give and sadly she is taken from us. My heart goes out to her family," he said.
DUP MLA Arlene Foster said: "This is tragic, that someone so young could be taken away like this is just shocking. My sympathies go out to Julianne's family and friends."
Meanwhile, shock and sadness has been expressed at Ms. Williams' passing, as family and friends take to a special tribute page on Facebook set up to remember her.

At the time of going to press yesterday evening, Ms. Williams' funeral preparations had not been made.
