NEW Lost Person Behaviour Course

Course Description

Lost Person Behaviour is one of the most critical elements of search operations during any lost/missing person situation. It provides in-depth information for search planners and team members on where best to look. A solid understanding of this subject area will greatly assist with the placement of resources into the correct location sooner. Faster finds result in fewer resources, less cost, and most importantly of all, a better chance of survival for the missing person.

The course focuses on lost and missing person behaviour primarily in a ground search environment. The course is intended to benefit both new and experienced search planners and team members with the latest information on this vital subject. It is not intended to provide in-depth instruction on search management or search planning.

The aim of the course is to provide participants with the tools and knowledge necessary to successfully look in the right place; to understand lost and missing person behaviour in depth; apply statistical tables constructed from databases which include 50,000 cases; identify the correct investigative requirements and deploy resources into the field in the right places.

The real value of this course lies in the database (ISRID) that supports the course text and the wealth of information contained on every subject category. The training is practical and will prove essential in every misper situation where a search is warranted.
