Lesson 3 • Chain of Custody Management
Establishes procedures for tracking evidence from collection through final disposition. A documented chain of custody is essential for evidentiary credibility.
Lesson 4 • Scene Assessment and Documentation
Teaches systematic scene examination, photography, sketching, and note-taking. Accurate scene documentation prevents loss of perishable evidence.

Introduces open-source methods for identifying assets, beneficial ownership, and financial relationships. Asset research supports fraud, corruption, and proceeds-of-crime investigations.
Lesson 4 • Public Records and Database Research
Covers access to corporate, property, court, and government records. Public records provide verified background data that corroborates or challenges subject information.
