Final answer:
Without sufficient context from the provided information, it is not possible to ascertain whether the deceased occupants were patients, doctors, nurses, or researchers. Epidemiologists are mentioned, indicating a public health concern, but speculation is not warranted.
Step-by-step explanation:
The information provided does not contain sufficient context to accurately determine who the two deceased occupants were. However, based on the mention of epidemiologists and the public health office, one could speculate that this situation may involve a public health investigation potentially related to an outbreak or medical incident. Epidemiologists often conduct interviews and review records to trace the source of health-related events. Still, without explicit details about the deceased occupants, it is irresponsible to guess whether they were patients, doctors, nurses, or researchers. It is essential to have comprehensive data before drawing any conclusions in situations pertaining to public health or medicine.
