What type of evidence consists of pieces that lead to a likely conclusion in an investigation?

Circumstantial evidence consists of pieces that lead to a likely conclusion in an investigation but do so indirectly rather than through direct proof. This type of evidence relies on inference to connect it to a conclusion, meaning that while it does not prove something outright, it can suggest a conclusion based on the context or surrounding facts. For instance, if someone was seen near a crime scene around the time the crime was committed, that observation serves as circumstantial evidence linking the person to potential involvement.

In contrast, direct evidence provides direct proof of a fact without needing inference, such as a witness testifying they saw a crime occur. Testimonial evidence is based on the accounts or statements given by witnesses, and conclusive evidence is definitive proof that leaves no room for doubt. Hence, the nature of circumstantial evidence makes it particularly useful in investigations where direct evidence might not be available, allowing investigators to build a case through a series of related facts that point toward a likely scenario.
