A body was recovered from Lough Erne in County Fermanagh on Monday during searches for a Limerick woman.
Carrie Mullane, 39, has been missing since last month.
Police believe that the mother-of-four was killed after shortly arriving in Enniskillen, Co. Fermanagh.
The PSNI say the body was recovered by a specialist police search team on Monday afternoon.
Detective Superintendent Richard Thornton, from the Police Service of Northern Ireland’s Serious Crime Branch, said: “Police have been in contact with Carrie Mullane (Noonan)’s family to inform them of this development, and we continue to provide them with support.
“We now must complete the formal identification process which may take a period of time.”
He continued: “Our investigation is continuing, and I’m keen to reiterate our appeal to anyone with information, no matter how insignificant it may seem, to contact us.”
