A complex investigation generally includes what?

A complex investigation typically involves multiple interconnected elements, which aligns with the understanding that it encompasses several simultaneous inquiries. This may include a variety of sources, such as multiple witnesses, various types of evidence, and collaboration across different investigative units or teams. In complex cases, the circumstances often require comprehensive approaches and contributions from various experts, types of evidence, and different investigative strategies.

For instance, in a complex fire investigation, several factors might need to be analyzed, including witness statements, forensic evidence, fire patterns, and other agency reports. This multifaceted nature distinguishes complex investigations from simpler cases, which might only require a single investigator’s focus or only the examination of physical evidence alone. Hence, having multiple simultaneous investigations as a part of a complex investigation allows for a thorough understanding and resolution of the case.
