A British man has been killed in a collision at an off-road vehicle event in Texas known as "Rednecks with Paychecks Spring Break".
Steven Fairbairn, from Newcastle upon Tyne, died from head injuries in hospital after the vehicle he was driving collided head-on with another all-terrain vehicle.
The crash happened on a dirt road within the grounds of the four-day festival and Mr Fairbairn was airlifted to a Fort Worth hospital, according to Montague County Sheriff's chief deputy Jack Lawson.
His death was ruled an accident, but his family has been frustrated by a lack of answers.
The 25-year-old's mother, Lynne Fairbairn, told WFAA television that organisers of the Rednecks with Paychecks event have not responded to their questions or offered condolences.
A post on the group's Facebook page on Monday described it as their "best ever event".
Mr Lawson said the group's owner, Derrick Morse, had been co-operating with the investigation into Mr Fairbairn's death.
Friends of the 25-year-old set up a Go Fund Me page to raise money for his fiance Abbey Green, whom he had proposed to two weeks before.
The page said his family was expected to travel to the couple's home in Duncan, Oklahoma, from the UK to say goodbye.
Organisers of Rednecks with Paychecks describe the event as "four days and nights of mud, rocks, music, camping, and friends".
It states that participants must be 18 or over, and must sign a waiver before arrival.
Miss Green told WFAA that the documents amount to "signing your life away" and called for the off-road event to be shut down.
In 2015, a 10-year-old boy was killed after an ATV crash at a Rednecks with Paychecks event.
