Direct evidence proves a fact directly through what someone observes or a confession, without needing to draw inferences. For example, an eyewitness stating they saw the defendant fire the gun, or a defendant’s own confession, directly establishes that the act occurred or that the person committed it.

Circumstantial evidence, on the other hand, requires reasoning to connect the dots and prove a fact. You don’t see the act itself; you rely on related facts that, taken together, lead you to conclude the fact. Examples include finding the defendant’s fingerprint on the weapon, locating the weapon at the scene, or showing the defendant was near the crime scene at the relevant time. These pieces require inference to conclude involvement.

Both types can support a conviction, and a jury can rely on strong circumstantial evidence alone if the inferences to guilt are reasonable beyond a reasonable doubt.
