Torquay crash: Suicide concerns about driver
Concerns over the state of mind of a driver involved in a fatal crash in Devon are being investigated.
Con and Elber Twomey, from the Irish Republic, were critically hurt in the crash in Torquay on Friday. Their son Oisin, two, and their unborn baby died.
The driver of the second car - believed to be a Polish national in his 20s from Torquay - was arrested at the scene, but later died.
It is understood a line of inquiry is that the local man was suicidal.
The Irish family, who were on holiday from their home in Meelin, County Cork, were driving along Hamelin Way when their Volkswagen Golf was involved in a head-on collision with a Vauxhall Vectra at 14:45 BST.
Devon and Cornwall Police said it appeared the driver of the black Vectra had gone down a hill and may have swerved into the path of the family's oncoming car.
Whether this was done deliberately, with the intention of killing himself, is being investigated.
The fatal crash has been referred to the Independent Police Complaints Commission because it was witnessed by a police officer.
Anyone who saw the crash, or who has any information, has been asked to contact police.
