After analyzing small paint chips from an auto accident, what information can a crime lab worker determine using the PDQ database?

The PDQ (Paint Data Query) database is a specialized resource used in forensic paint analysis that focuses on providing information regarding the year, make, and model of a vehicle associated with paint samples. When a crime lab worker analyzes paint chips, they can compare the physical and chemical characteristics of those chips to the extensive database of paint formulations and types used by various vehicle manufacturers over the years. This allows them to narrow down which vehicle the paint likely originated from, significantly aiding in investigations that involve auto accidents.

This capability stands out as a crucial aspect of forensic analysis because identifying the specific make and model of a vehicle can link it to a crime scene or accident, providing valuable context and potentially leading to further investigative leads.
