Trace Evidence Unit
The Trace Evidence Unit analyzes a broad spectrum of physical evidence to determine if the evidence could be connected to a suspect or victim. In addition, the Trace Evidence Unit examines a variety of substances for identification or comparison purposes. The Trace Evidence Unit is located at the Milwaukee Laboratory. To support the unit, there are two Trace Evidence positions.
