The search for the tragic 22 year old has now entered its second week since he went missing in the early hours of Sunday week last.
His distraught family including dad Joseph, three brothers and one sister have been waiting at the banks of the Rivers Finn, Foyle and Mourne for the past seven days waiting for a sign that David has been recovered.
Hundreds have joined the search for the young man from Beechwood Grove who was last seen after escaping police custody after being arrested for being drunk and disorderly.
To date the water has been very murky which has prevented many divers, including the PSNI team, from diving.
Last night a source close to the family say they are hopeful that when the water on the rivers subsides, there will be more chance of finding David.
“They just want him home now. Each passing day is agony for them. They know he’s not alive but they just want their son and brother back.
“People have been very good and everyone is just wishing now that David will be found soon,” he said.
