Cops are continuing to comb woodlands in a bid to find the body of missing Saoirse Smyth.
Police fear the west Belfast woman was killed by a drugs gangster and dumped in a shallow grave at an Omeath forest, Co Louth.
Saoirse, 28, vanished in April 2017 and PSNI bosses have traced her final movements back to the border town where she was staying in a holiday home.
Detective Chief Inspector Darren McCarthy said: “Inquiries have led us to believe that she has been murdered.”
The PSNI has joined forces with gardai on the murder probe.
Teams began searching a wooded area off the Ferryhill Road in Omeath yesterday morning.
The search is expected to last up to two weeks.
