The 14-year-old schoolgirl was last spotted on Dillon Bridge, not far from her home, at around 10 PM.
A major search operation was launched, which included gardaí, the Civil Defence and the Garda sub aqua unit.
Last night, a body was spotted in the water of the River Suir by members of the Coast Guard helicopter crew who were also involved in the search.
Early this morning, the identification was confirmed as that of the local missing girl.
The remains of 14-year-old were discovered around 8 kilometres from where she was last seen alive.
Her remains have been transferred to University Hospital Waterford, where a post-mortem is expected to be carried out.
In a statement, gardaí paid tribute to the hundreds of search volunteers who had supported the massive search operation.
