Gardaí have ruled out upgrading any further missing persons cases to murder investigations - including that of Naas man Trevor Deely, who vanished in Dublin in December 2000.

The cases will remain under review, but no new resources are being allocated unless fresh evidence emerges.
Searches for Annie McCarrick's remains have been carried out in Clondalkin, following her case being upgraded to a murder investigation last year - three decades after her disappearance.
