Which action best describes investigators' focus during the investigative phase?

• A. Become totally familiar with all aspects of the case
• B. Present case to ADA or AUSA and coordinate prosecution
• C. Review evidence and direct lab examinations
• D. Develop and prioritize suspects

Answer: (C)

The main idea being tested is that, during the investigative phase, the focus is on turning collected material into usable information by guiding laboratory work. Investigators review what has been gathered, assess its significance, and determine what analyses the forensic lab should perform. This involves selecting appropriate tests, requesting specific examinations, and ensuring samples are handled properly so results are reliable and can be interpreted in the context of the case. By directing lab examinations and closely evaluating the evidence, investigators build a factual basis that can support or refute theories about what happened, who was involved, and how events unfolded.

Other aspects like becoming completely familiar with every detail, presenting the case to prosecutors, or merely pursuing suspect lists are components of the broader process, but the essential task that defines the investigative phase is coordinating and interpreting laboratory work in light of the evidence.
