Post-mortem examinations have been completed on the bodies of a woman and a man recovered by divers from the River Lee, near Cork city centre last night.
It is understood that the post-mortem examinations revealed no indications of violence and the deaths are being treated as a tragic accident.
Formal identification is not expected to be completed until tomorrow.
However, it is believed that the bodies are those of 27-year old Michelle O'Riordan, who had been reported missing from Cork city, and 53-year old Paddy O'Driscoll, who was originally from the March Road in Skibbereen in west Cork.
Both were last seen on 4 December and both were using the services of homeless agencies in Cork prior to their disappearance.
Investigating gardaí will now compile a file for the coroner's office and inquests into the two deaths are expected to take place later.
Earlier, Ms O'Riordan's mother described her as being full of life and always happy.
Speaking this afternoon Michelle's mother, Rita Murphy, said the family was devastated and could not believe what had happened.
She described Michelle as a person who loved her friends and loved being with people.
She said her daughter was a decent person who was always good to other people.
Homeless agencies say their services are under unprecedented pressure, with the number of people becoming homeless rising steadily.
St Vincent de Paul in Cork provides accommodation for 120 homeless people in the city every night and it is calling for longer-term solutions.
Minister for the Environment Alan Kelly is currently considering a proposal from Cork City Council to provide 20 emergency beds for the remainder of the winter at least.
