Double tragedy car crash 'would have been impossible to survive'
Three people killed in separate overnight road tragedies
The sister of a double murderer has died in an horrific car crash which also claimed the life of a young man.
Gardai have appealed for witnesses to the single vehicle crash at Carrignavar, north of Cork city, which claimed the lives of Ann-Marie O'Connor (45) and John Paul O'Carroll (31).
Separately, a male pedestrian was killed by a hit-and-run driver in Swords, Co Dublin, just after 3am. Gardai are also appealing for information from anyone who may have been in the North Street area of Swords at the time.
The double fatality in Cork occurred at Ballinahan, Carrignavar shortly before 12.30am yesterday when the couple's red Hyundai coupe apparently spun out of control. The vehicle struck a ditch, became air-borne by a small hill and then crashed upside-down into a stone pier. Both occupants of the car were killed instantly.
A Garda source said it would have been impossible for anyone to have survived the impact, the vehicle was torn apart by the force of the crash.
Gardai are satisfied no other vehicle was involved.
The bodies of both deceased were taken to Cork University Hospital (CUH) where full post mortem examinations were scheduled to be carried out last night.
The road was closed by gardai to allow for a detailed examination by forensic crash scene investigators.
Mayfield gardai have appealed to anyone with information about the accident or the movements of the vehicle between 11pm and 12.30am to contact Mayfield Garda Station at (021) 4558510 or the Garda Confidential Line (1800) 666111.
Ms O'Connor, with an address at Kilbrogan, Bandon, Co Cork, was the older sister of Catherine O'Connor who was convicted of two murders in west Cork three years ago.
Mr O'Carroll was from Farranferris Park, Farranree, Cork.
Catherine O'Connor (39), a mother of three, was convicted of the murder of English father-of-four John Forrester (42) and Corkman, Jonathan 'Dukie' Duke (27) at Bridge House, Bandon in west Cork on November 11/12, 2011.
She was convicted of the double murder alongside her then Romanian boyfriend, Ciprian Grozavu (40).
Both are now serving life sentences handed down by the Central Criminal Court.
Mr Forrester was savagely bludgeoned to death in a drunken row over Catherine O'Connor's new relationship with Grozavu.
The Englishman, who had a serious alcohol problem, had been in a relationship with Catherine O'Connor.
His body, which had been repeatedly stabbed with a broken Manchester United mug, was dumped into the River Bandon directly outside Bridge House. Mr Duke was then killed hours later amid fears that he knew what had happened to Mr Forrester.
The Corkman's body was dumped into the River Bandon, but other occupants of the flats complex saw what had happened and immediately alerted gardai.
The body of Mr Duke, a father of one, was recovered within hours by gardai and the body of Mr Forrester was found 2km downstream the following day.
