Final answer:
Canine search teams are the accurate method to locate dead bodies, as they use their strong sense of smell to find human remains.
Step-by-step explanation:
The method by which dead bodies can be located outside of the options listed would most accurately be canine search teams. These specially trained dogs use their keen sense of smell to locate human remains. Other methods, such as psychic mediums, lack the empirical evidence to be considered reliable, and while social media might help in alerting the public or gathering tips, it is not a direct method of location. Satellite tracking is generally used for real-time location tracking rather than finding remains.
