An inquest in to the death of a South Gloucestershire family killed in a Florida car crash has been delayed.

The inquest in to the deaths of Sheralyn Stephenson, a secretary who worked in Thornbury, her husband Bryan, originally from Yate, their son Adam and daughter-in-law Maryanne was due to be heard at Avon coroner's court on October 3.

It has now been delayed to allow further evidence to be gathered.

The family, who lived near Warmley in South Gloucestershire, had been on holiday at the time of the crash on April 2.

It is believed they were returning to their accommodation from a visit to the Kennedy Space Centre, when their hired Mitsubishi hit a pick-up truck on State Road 405 at Sisson Road.

The heavy-duty truck violently impacted the passenger side of the small sedan and, despite emergency personnel arriving on the scene within a few minutes, all four were pronounced dead at the scene.

The driver of the truck sustained non-life-threatening injuries.

GPS in the vehicle was instructing a "U-turn" at the intersection, most likely because of an earlier crash with road blockage on SR 407 - which was the original GPS route from the Space Center for their trip back to Davenport.

A new date for the inquest is yet to be confirmed.
