IF it’s an accidental release I’m sticking to my original hypothesis:
Improper building codes for the bioweapons lab. Corruption is rampant. Someone didn’t follow the building diagram to hook this to that (example, waste water was dumped directly into the river/lake/sewer instead of the biohazard handling facility).
Lab subsequently infested with mice/rats/etc. Creatures in the sewer exposed, etc.
Improperly handled research samples thus transferred to the outside animal population.
One of which was killed and butchered ‘messily’ and there we go...
I can see that
Fort Detrick couldn’t even get safety right as per CDC.
I dont think intentional release.
I do think it is related to that bioweapons lab.
