What part of the BPS field indicates a body part is not recovered?

In the context of the BPS field, the designation "N" specifically signifies that a body part is not recovered. This is a standardized notation used to ensure consistent communication about the status of evidence or remains in investigations. When agents encounter a situation where a body part is missing or unaccounted for, noting it as "N" allows for clear understanding among law enforcement and related agencies involved in the case.

The other designations in the BPS field serve different purposes, designating either fully recovered or specific conditions of the body parts. Understanding what each letter represents is crucial for effective data entry and retrieval in investigation systems, ensuring all information is accurately conveyed and understood among the investigating parties.
