“Whilst of course at this stage we do not know the full facts, and cannot rule anything out until we do, it is wrong to assume and of course confirm that she was raped and murdered by a mystery assailant when such facts are not evident. Facebook posts analysing photographs of poor Catherine’s body are totally unacceptable.”
Miss Shaw’s parents, Ann and Tarquin Shaw, said: “Catherine just loved mountains and sunrises. She died doing what she loved.”
The couple, who have another daughter, Jenny, 22, thanked the friends, local volunteers, search and rescue teams for their help throughout the six-day search.
“We wish it to be known how grateful our family are for the huge response locally and across the world in our search for Catherine and for the vast amount of messages of support,” they said.
“Thank you seems insufficient but it is very heartfelt, so thank you.”
Mr Shaw was due to arrive in Guatemala on Monday night.
