Post mortem examinations have been completed on the bodies of two men who died from suspected drug overdoses at a house in Cork city on Christmas Day.

John Foley, 33, of Mayfield, Cork, and John O'Donoghue, 32, who had an address at St Vincent's Hostel, Anglesea Street, Cork had been attending a party at Rockgrove Terrace, off the Lower Glanmire Road.

The exact cause of their deaths will not be known for some time.

It was a Christmas party fuelled by drink and drugs which had a tragic and fatal outcome.

On Christmas Eve, around a dozen people gathered at a house at Rockgrove Terrace off the Lower Glanmire Road in Cork for a party which continued well into Christmas Day.

Two of the people there are believed to have taken a lethal cocktail of drugs which cost them their lives.

John Foley died at the house and was pronounced dead there at lunchtime on Christmas day.

John O'Donoghue died yesterday morning in hospital after becoming ill at the house on Christmas night.

Throughout Christmas day and yesterday, gardaí set about the difficult logistical exercise of tracing the other ten people at the house party.

Just one of them remained outstanding late last night.
