The content of the investigation report was about a series of incidents that occurred in June of 1992 at a research institution named the 955 Institute. Forty-seven researchers and related staff members died during these incidents. Apart from those who died in a fire later, most died of sudden unexplained death, with their internal organs experiencing large-scale necrosis prior to their demise. Yet, the cause could not be determined even after autopsies.
Some details in the investigation report indicated that the 955 Institute was the official research institution focused on "mutants".Moreover, just before this series of severe incidents, the 955 Institute had just captured a live specimen of a "Blood-eating Creature" and had conducted over two months of research on it, already reporting substantial findings to higher authorities.
