Mr Brooke Pickard diappeared from Castlecove in April 1991.
A witness reported seeing Mr Brooke Pickard being bundled into a van at the time he disappeared in 1991.
The van was later found burned out but there was no evidence to help in locating Mr Brooke Pickard.
Extensive searches involving army and Garda personnel have taken place in Derrennageeha, Ballaghisheen near Waterville over the last few weeks.
The operation was put in place following a recent television appeal for new information.
There were a number of arrests in the immediate aftermath of the abduction but none in recent years.
The search ended yesterday evening without Mr Brooke Pickard’s body being found.
