Finding missing people using probabilities

I found this interesting article about a system of using mathematical probability to determine where a lost person might have gone and what condition they’re in now. There’s actually a book about this, Lost Person Behavior by Robert Koester, called “the search manager’s Bible.” Factors include the missing person’s age, mental status and physical condition, as well as the terrain, the weather and the time of day.

This sounds like a really cool idea and it actually works, too. When a person is lost, time is of the essence in finding them, and having a general idea of where to look is a big help.
