What investigative method involves searching trash left outside a suspect's residence?

The investigative method that involves searching trash left outside a suspect's residence is known as a trash run or trash pull. This technique is often employed in investigations to gather evidence that may not be easily accessible through other means. When investigators conduct a trash run, they sift through discarded items, such as documents, receipts, or other personal belongings, which can provide valuable information about a suspect's activities, associations, or even criminal behavior. It is a legal and practical approach to obtain evidence that can inform further investigative steps or confirm existing leads.

This method can uncover usable material that might not be available through more traditional investigative practices and is especially useful when there's reason to suspect that the individual is engaged in unlawful activities. The proper execution of this investigative tactic ensures that evidence is collected in a manner that is admissible in court, providing a solid foundation for building a case.
