During a search of a residence for illegal drugs, what else should investigators look for?

In the context of searching a residence for illegal drugs, while intelligence information is indeed crucial, the broader scope of a drug-related investigation should include various types of evidence that can support the overall case. While the answer emphasizes intelligence information, the most comprehensive response is that investigators should look for all relevant aspects, including weapons and personal items, as they can indicate the nature of the drug operation, the potential for violence, or connections to other criminal activities.

Intelligence information assists in understanding the drug trade network, identifying suspects, and providing context for the drug-related activities observed. This kind of information often encompasses records, communication devices or notes that can aid in constructing a larger narrative around drug trafficking. However, the presence of weapons might suggest the potential for violent encounters, and personal items can provide insight into the lifestyle of the individuals involved or their connections to other criminal elements. Thus, a thorough investigation would take into account all these elements, rather than focusing on just one aspect.
