They should just be looking for vultures ( or similar scavengers) !!


When a human or other mammal body is starting to fail, the body exudes (primarily through breathing) smells (chemicals) that vultures are able to interpret as a sign of imminent death. Basically, the body’s systems are failing and the escaping odors are a side-effect. Vultures can smell this from several miles away. Ravens and crows seem also to know if an animal is dying, but most other land birds have little sense of smell.

In the 1920s employees of Standard Oil in California noticed that vulture always seemed to be circling the gas-pipeline leaks the employees were looking for. It turned out that dead bodies emit ethyl mercaptan, a chemical contained in natural gas.
