Lost Person Behavior

About This Class:

The Lost Person Behavior Workshop was developed by Mr. Robert Koester, author of the book “Lost Person Behavior”. Lost person behavior is the cornerstone of search and rescue efforts. Based upon a landmark study, this book is the definitive guide to solving the puzzle of where a lost person might be found. Nowhere else is it possible to learn about the latest subject categories, behavioral profiles, up to date statistics, suggested initial tasks, and specialized investigative questions. This book delivers what search managers need.

Participants will not only gain a full understanding of 41 subject categories contained within the Lost Person Behavior profiles, which have been compiled from the latest search and rescue incident statistics from the International Search and Rescue Incident Database (ISRID), but also receive a workbook along with in-depth instruction and case studies that goes above and beyond the book.
