66: The Criminologist Who Pioneered Geographic Profiling | Case Notes

Can the geography of a serial killer's crimes reveal where they live, how they hunt, and where they might strike next?

In this episode of UNMARKED: Case Notes, I sit down with Dr. Kim Rossmo, the pioneering criminologist who developed modern geographic profiling, a technique that has changed the way police investigate serial murder.

A former detective inspector with the Vancouver Police Department and now a professor at Texas State University, Dr. Rossmo developed a mathematical approach to analyzing crime locations that helps investigators identify an offender's likely home base, hunting grounds, and patterns of movement.

We explore the science behind geographic profiling, what the locations of murders can reveal about a serial killer's behaviour, how offenders select victims and hunting grounds, and how investigators use geographic patterns to narrow the search for an unknown killer.
