The recovery of evidence is a destructive process that cannot be repeated: this applies to the recovery of buried human remains (regardless of the preservation) and other associated or related evidence. Consequently, in both archaeological and forensic contexts it is imperative that buried evidence is recovered correctly from the beginning as the process is an unrepeatable experience.
