This is a fascinating account of the need to look beyond the boxes that you can check on a death certificate.
For instance, an unhoused person found dead with drugs in their blood didn't necessarily die of a drug overdose. Some drugs inhibit sweating, some make you more active, others make you feel the heat less so you don't take precautions.
Going to the scene of death with a thermometer needs to become a routine thing - but is not.
