What defines a catastrophe victim in the context of unidentified records?

A catastrophe victim is characterized specifically by their unknown identity, particularly in situations involving mass casualties or disasters where the victims may not be easily identifiable. The focus on "unidentified records" emphasizes that these individuals are part of a larger context where identification is hindered due to the extreme circumstances of the event, such as natural disasters or terrorist attacks. This situation often leads to complexities in recovery and identification processes, making it vital to correctly categorize them as victims of catastrophe with unknown identities.

The other options do not align with this definition. Knowing a victim's identity or having an intact body suggests a standard recovery scenario where identification can occur. However, in the catastrophic context, such conditions often do not apply due to the nature of the events, reinforcing why the distinction of 'unknown identity' is crucial in defining a catastrophe victim.
