‘We can’t process the evilness of it all’
Two of the creatures, Pleasance and Gabrielle, who was pregnant, were found dead in their shelter on 6 January.
A four-month-old alpaca named Ragamuffin was also found dead in the shelter the following day.
Their bodies were taken to a vet for a post-mortem examination, which showed all three animals had suffered blunt force trauma.
Lesley and Andrew Sapsford, who live on a farm in Little Kingshill, Great Missenden, are now worried about the safety of their remaining 80 alpacas.
“Somebody has purposely done this and they did it in the shelter so that they couldn’t be seen,” said Mrs Sapsford. “We are heartbroken and devastated – we can’t believe that anybody would be so cruel.
“At this time of year there isn’t any grass on the field so we feed them concentrate, which means they would have seen someone coming onto the field thinking they were going to be fed.
“Our alpacas have never been treated badly by a human before. We can’t process the evilness of it all. We’re so worried about our other alpacas now. Whoever has done this could do it again.
“If anyone saw anything, heard our alpacas screaming, saw any strange cars – anything at all which would give us a lead – please report it to the RSPCA or the police.”
Rachel Smith, the RSPCA inspector investigating the case, also urged anyone with any information to come forward.
“This is a sickening act of cruelty which has left the owners devastated,” she said. “It is very concerning that someone would think it acceptable to do this to an animal.”
