A remembrance service is taking place in County Down for murdered Bangor woman Lisa Dorrian.
Lisa Dorrian's body has never been found
Lisa, 25, was last seen at a party on a County Down caravan site in February. Her body has never been found.
Police believe members of the Loyalist Volunteer Force, which said on Sunday that it was standing down, may have been involved in her killing.
The service is being held in the Church of the Holy Redeemer in Ballyholme, Bangor.
On Wednesday, it was confirmed that a forensic scientist looking at the cases of the Disappeared will also be able to work on Lisa's case.
The forensic scientist is being funded by the British and Irish governments to help locate the remains of five people abducted, murdered and secretly buried by the IRA during the Troubles.
Northern Ireland Secretary Peter Hain said the police would be able to use the scientist to undertake other work on an independent consultancy basis.
