What piece of evidence would you look for on a suspect's clothing after they were involved in a burglary related to a safe opened by an explosion?

In a burglary involving a safe opened by an explosion, the presence of insulation material on a suspect's clothing is relevant for several reasons. Typically, such explosive activities may involve the interaction with safes that are often insulated for security. If the safe was located in a construction environment, such as a building with insulated walls or ceilings, it's plausible that the explosion could dislodge or release insulation material from those surfaces, resulting in contamination of the suspect's clothing.

Furthermore, insulation materials can be distinctive and identifiable, allowing forensic analysts to potentially match the type of insulation found on the suspect's clothing to the location where the burglary took place. This could provide critical links between the suspect and the crime scene, thereby strengthening the case against them.

While charred metal fragments might be relevant due to the nature of the explosive device used, they may not be as visible or conclusive as insulation material. Cement dust could indicate a construction site but lacks direct relevance to the specific nature of the crime unless the cement is somehow connected to the explosion's cause. Blood stains could suggest physical altercations or injuries but are not directly tied to the operational method of the burglary involving explosives. Hence, insulation material emerges as a more pertinent piece of evidence in this specific investigative context
