However, her reply to him failed to deliver to his phone.The body of Mr Webb was found in water in a ravine almost a week later in an area that local police said had many cliffs, deep gorges and slippery surfaces.Local police concluded that Mr Webb had drowned while unconscious after a fall in water, and his parents requested that a post-mortem examination was not carried out in Vietnam.A post-mortem examination was conducted after his body was repatriated to the UK, but failed to establish a cause of death – partly as the body had been embalmed.The examination noted cuts and scratches caused by climbing, but no fractures or haemorrhages.Yvonne Blake, area coroner for Norfolk, recorded an open conclusion at Monday’s hearing at Norfolk Coroner’s Court in Norwich, which was not attended by any of Mr Webb’s family.”We know that he was trying to climb Fansipan mountain alone,” said Ms Blake. “We know that he got into difficulties, he was injured and had a deep cut on his arm.”He said he badly hurt his knee and couldn’t move very well, and we know he was found in a stream.”The medical cause of death was unascertained as he was embalmed.”She extended her condolences to the family of Mr Webb, who was born in Norwich, lived in Attleborough, Norfolk, and had been a student at Anglia Ruskin University in Cambridge.His parents Simone and Trevor Webb said in a written statement: “Aiden was such a joy to be around. “We’re incredibly close as a family and feel privileged to have been his parents.”They praised everyone who had been involved in the recovery of their son’s body.
