The family of Noah Donohoe say they hope an inquest into his death will "assist in answering outstanding questions".
A preliminary hearing of the inquest into the death of Noah, 14, will take place tomorrow at 12pm at Laganside Courthouse, Belfast - this will be the first such hearing.
An appeal was made to the public in a statement issued on behalf of Noah's mum Fiona through Relatives for Justice.
The statement read: "As reported in media last week the preliminary findings of the autopsy are that Noah died as a result of drowning, and that he did not suffer a severe head injury.
"It is the family’s hope that the inquest will assist in answering the outstanding questions of how Noah was in a state of undress, and how he met his death in a storm drain.
"Once again the family is making an appeal to the public to desist from conspiracy theorising and speculation and instead assist with factual information. Every single small piece of information will assist in the recovery of the answers to these heart-breaking and painful questions.
"We specifically appeal to any householder in the Shore Road area who has CCTV in their homes to please keep the footage from the 21st June, not to over write it and please share it with the PSNI, RFJ or KRW Law. This will be treated in confidence.
"Please contact: info@relativesforjustice or niallm@kevinrwinters.com."
