Which type of workers are typically contacted for information during a crime investigation?

Construction and utility workers are often contacted for information during a crime investigation due to their unique position and interactions with various locations and infrastructure. These workers can provide crucial insights into timelines, activities in a specific area, or any unusual occurrences they may have witnessed while performing their tasks. Their presence at the scene of a crime or in the vicinity can yield valuable information on potential suspects, vehicle descriptions, or even contextual elements that may contribute to the investigative process.

In contrast, the other groups mentioned, such as office workers, retail employees, and healthcare professionals may also have relevant information, but their roles and interactions with the physical environment or specific crime scenes may not provide the same breadth of relevant observational data as construction and utility workers, who frequently engage with accessible locations and experiences in a manner that can directly correlate to criminal activity.
