Circumstantial Evidence

Circumstantial evidence is indirect evidence — proof of one fact that allows a jury to infer another fact. If someone sees a person walk out of a house carrying a TV at 3 a.m., that is not direct proof of burglary, but it is circumstantial evidence that supports the inference. Despite popular belief, circumstantial evidence is not “weaker” than direct evidence under California law.

How Circumstantial Evidence Works in California

California Evidence Code § 600 defines an inference as a deduction of fact that may be drawn from another fact. The standard California jury instruction on circumstantial evidence — CALCRIM 224 — tells jurors that before they may rely on circumstantial evidence to convict, they must be convinced that the only reasonable conclusion supported by it is guilt. If two reasonable interpretations exist — one pointing to guilt and one to innocence — they must adopt the interpretation pointing to innocence.

This rule is uniquely important in California criminal cases that depend heavily on circumstantial evidence, such as drug possession with intent to sell, conspiracy, financial crimes, and many homicides. Fingerprints, DNA, surveillance footage, GPS data, phone records, and pattern-of-conduct evidence are all common examples. Each piece may seem damning in isolation but often supports multiple reasonable interpretations once examined carefully.

Why Circumstantial Evidence Matters to Your Defense

A strong defense exploits the gap between what circumstantial evidence proves and what the prosecution claims it proves. Just because a defendant’s DNA was on an object does not mean they committed a crime with it. Just because phone data places someone near a location does not mean they participated in what happened there. Skilled criminal defense attorneys present alternative reasonable interpretations and remind the jury — through CALCRIM 224 — that they are required by law to adopt the innocent interpretation if it is reasonable.

This work often involves expert witnesses. Forensic experts can challenge how DNA samples were collected and analyzed, digital forensic experts can explain limitations of cell tower data, and accident reconstruction experts can offer alternative explanations for physical evidence. Each expert helps the jury see that circumstantial evidence rarely tells just one story.

Circumstantial evidence sits opposite direct evidence and is closely tied to the standards of beyond a reasonable doubt and the role of expert witness testimony at trial. These concepts come up constantly in our criminal defense and DUI defense work across Greater Los Angeles.
