A paramedic with more than ten years’ experience said that a car accident in which a mother and her two teenage sons were seriously injured was the most horrific he had ever seen.

Great Western Ambulance Service paramedic and clinical team leader, Ross Culligan, was the first paramedic to arrive on the scene of the collision close to Kingsdown Golf Club, near Box.

He said: “It was absolute devastation with catastrophic injuries.”

Carey Gay was driving her two teenage sons in her silver Toyota Avensis when it was in a collision with a black Range Rover on Tuesday morning.

Mr Culligan said that when he arrived at the scene at around 8.22am, the 29-year-old driver of the Range Rover had got out of the upturned car with only minor injuries.

Mr Culligan went to the Avensis where he saw that the 13-year-old boy in the back, Ryan Gay, wasn’t breathing.

He told Martyn Heath and Dave Seabright, the two golf club green keepers who were the first on the scene, to keep Ryan’s airways open and keep pressure on his wounds.

Mr Culligan then found Ryan’s brother Andrew and mother Carey trapped in the front. She was unconscious throughout.

Mr Culligan said: “I have been a paramedic for ten years and I have never seen anything like this.”

Two fire appliances from Corsham and three ambulance crews arrived at the scene shortly afterwards, followed by the Wiltshire Ambulance.

Paramedics and firefighters worked together to release Mrs Carey and Andrew from the car, while Ryan was airlifted to Bath’s Royal United Hospital.

He was later transferred to Bristol Royal Hospital for Children.

The air ambulance returned to take Mrs Gay and Andrew to the RUH and Mrs Gay was later transferred to Frenchay Hospital in Bristol. All three are in intensive care.

Golf club manager Neil Newman said he has written to the highways department on numerous occasions asking them to reduce the speed on the unclassified road, which around 30,000 golfers cross each year.

Mr Newman said: “I have never seen an accident of that extent before here but the road is very dangerous.

“I have written two or three letters to highways over the last few years.”

He added that the club also put in a reflective mirror on the blind junction where the accident happened.

Witnesses to the accident are being urged to call the serious collision investigation team on 0845 408 7000.

The police would also like to hear from anyone who saw the Range Rover before the accident.
