CCTV security camera footage now holds the key to explaining a horrific UK crash that claimed the life of a 16-month-old Irish toddler and his unborn baby sister.
Oisin Twomey (16 months) and his unborn sister, Elber Marie, died when the Volkswagen Golf driven by their parents, Con (39) and Elber (36) Twomey, was involved in a head-on collision on July 6 outside Torquay in Devon.
Con and Elber are still fighting for their lives in Derriford Hospital in Plymouth.
A coroner's inquest today set to allow the Twomey family bring Oisin and Elber Marie's remains back to Ireland.
The inquest will hear outline details of the cause of death before being adjourned to allow the police inquiries proceed.
It will also deal with the third fatality from the tragedy, Polish taxi driver Marek Wojciechowski (20).
The coroner will be able to issue an interim death certificate which will allow Oisin's body to be returned to Cork.
Oisin's remains will be brought back to Meelin alongside those of his sister, Elber Marie, who was due to have been delivered in December.
Elber Marie did not survive emergency surgery to save her.
Funeral arrangements will only be confirmed in light of an update on the medical condition of Con and Elber.
The tragedy occurred when the Twomey's car was struck by a Vauxhall Vectra being driven by Mr Wojciechowski.
The Vectra apparently veered directly at high speed into the path of the Twomey's Golf.
CCTV security camera footage is now believed to be central to explaining the circumstances of the accident and the manner of Mr Wojciechowski's driving in the minutes before the collision.
While the crash itself was not caught on camera, footage from business premises in Torquay and leading to Hamelin Way, where the collision occurred, is being studied.
It is hoped this will determine the speed of the Vectra - and whether Mr Wojciechowski's driving was erratic.
It is also expected to confirm that Devon police were not in pursuit of the vehicle at the time.
Devon police are hoping to speak with people travelling on Hamelin Way at the time.
Three probes are now under way into the collision including inquiries by Devon police, the Independent Police Complaints Commission (IPCC) and the Plymouth coroner.
Devon police confirmed they were looking for Mr Wojciechowski after a friend had raised concerns about his welfare.
