Final answer:
An evidence recovery kit should include self-sealing plastic bags, clean gauze, and a camera.
Step-by-step explanation:
An evidence recovery kit should contain self-sealing plastic bags, clean gauze, and a camera. The self-sealing plastic bags are important for preserving and containing any physical evidence without contamination. Clean gauze is used to collect biological evidence such as DNA or trace evidence.
The camera, preferably a digital one, is used to document the condition and location of the evidence for future analysis and presentation in court if necessary.
