Gabriele Cairo pleads guilty to causing deaths of Cynthia, John and Jacquie Clark in Everard Central, South Australia

An Italian travel blogger has pleaded guilty to causing the deaths of a woman and her elderly parents in a car crash during his honeymoon in South Australia.

Gabriele Cairo, 28, faced the Adelaide Magistrates Court on Tuesday where he admitted three counts of causing death by dangerous driving at Everard Central in the state’s mid-state on October 31 last year.

Cairo was behind the wheel of a van when it collided with a Honda Civic carrying Cynthia Clark, 84, her husband John, 86, and their 54-year-old daughter Jacquie.

Mrs Clark and her daughter died at the scene of the accident, while Mr Clarke, who was in the back of the Honda, suffered serious injuries and was flown to hospital for treatment.

He died a few days later.

Cairo also pleaded guilty to causing serious harm to his wife Elena Perrone, who was also in the van and was taken to hospital with serious injuries.

Mrs. Perrone wept in the courtroom as her husband admitted the charges.

The couple, from Italy, were celebrating their recent wedding during a trip to South Australia at the time of the crash.

A charge of aggravated driving without the right car was dropped in court on Tuesday, with Cairo’s lawyer asking for a conviction to be handed down as soon as possible.

His lawyer said Cairo was “devastated” by the events.

Cairo and members of the Clark family declined to speak outside court.

The 28-year-old will remain on bail until his next appearance in July.
