A local poster on here said that people dump dead sheep there (uggggh) Could that be adding to the confusion re the remains? Also possibly why they need so many people there for so long to check through everything they find?
JMO - they're bound to be checking everything. Not just because standards are high anyhow, but because the revulsion as expressed by Cressida Dick yesterday means no one is going to chance a prosecution failing on a procedural issue
If it's a sheep carcass dumping ground, there will be carnivorous wildlife. So state of a deceased person might not be solely down to human actions
