What type of evidence should be placed in a paper bag?

Placing wet evidence in a paper bag is appropriate because paper allows for evaporation, which helps to prevent the growth of mold and the deterioration of the evidence. Unlike plastic bags, which can trap moisture and create a breeding ground for bacteria and harmful fungi, a paper bag provides a breathable environment. This is crucial for preserving the integrity of wet evidence, ensuring that it remains usable for forensic analysis.

Other types of evidence, such as solid objects or evidence in any condition, may not necessarily require special handling in a paper bag. Solid objects can often be placed in various types of containers depending on their size and nature without the risk of degradation. The option regarding only important evidence does not apply here, as the condition of the evidence, rather than its importance, dictates the appropriate packaging method. Thus, for maintaining the quality of wet evidence, paper bags are the preferred choice.
