Navy divers, members of the coastguard and volunteers will resume the search for the grandson of the founder of Penneys this morning.
The search for 21 year old Barry Davis Ryan - off the west Cork coast - has been continuing since he, his girlfriend and his father went into the sea on Tuesday evening.
The remains of Niamh O'Connor from Glanmire and Barry Ryan senior have since been recovered.
The two men had jumped into the sea at Baltimore after Niamh was pulled out by a wave.
