_ grounded in psychological theory.
What is investigative psychology?
- It is statistical analysis + psychological theory to analyse crime scenes.
- aims to establish patterns as behaviour that are likely to occur across crime scenes.

- it can also be used to predict where they an next likely to commit a crime-jeopardy surface
- individuals construct mental maps of the areas they know - not always accurate -shows distribution of linked offenders.
