A teenage girl was the latest victim on a weekend of "appalling" carnage on Irish roads that claimed seven lives in less than 48 hours.
Roisin Hession (16), from Tuam in Co Galway, was a passenger in a car that crashed into a wall and ended up on its roof in a single-vehicle crash at Porridgetown near Oughterard at 1.15am yesterday.
Her body was removed to the mortuary in University Hospital Galway, where a post-mortem was due to take place.
The male driver of the car (21) suffered serious but not life-threatening injuries.
Gardai in Salthill, Co Galway, are appealing to road users who may have travelled the route and can assist them, or drivers who may have dash cam footage, to call them at Salthill Garda Station (091 514720), the Garda Confidential Line (1800 666 111) or any garda station.
The fatality followed six deaths on the nation's roads between Friday night and Saturday morning.
The loss of life has been described as "an appalling level of carnage" by the Road Safety Authority.
In the worst single loss of life, three people were killed following a two-car collision in Co Louth in the early hours of Saturday morning.
The crash happened at about 2.15am on the N1 at Carrickcarnan, south of Junction 20 on the main Dublin to Belfast road near Dundalk.
A mother and son, Mary (88) and Kevin Faxton (58), from Bessbrook in Newry, were pronounced dead in one car. In the second car, Brian McGill (25), also from Newry, was killed.
Their bodies were removed to Our Lady of Lourdes Hospital in Drogheda.
A man in his 20s in the second car was also seriously injured in the crash.
He was also taken to Our Lady of Lourdes Hospital for treatment.
