=== Validity of circumstantial evidence === A popular misconception is that circumstantial evidence is less valid or less important than direct evidence, which is popularly assumed to be the most powerful, but this is not the case. Many successful criminal prosecutions rely largely or entirely on circumstantial evidence, and civil charges are frequently based on circumstantial or indirect evidence. The common metaphor for the strongest possible evidence in any case—the "smoking gun"—is an example of proof based on circumstantial evidence. Similarly, fingerprint evidence, videotapes, sound recordings, photographs, and many other examples of physical evidence that support the drawing of an inference, i.e. circumstantial evidence, are considered very strong possible evidence. In practice, circumstantial evidence can have an advantage over direct evidence in that it can come from multiple sources that check and reinforce each other. Eyewitness testimony can be inaccurate at times, and many persons have been convicted on the basis of perjured or otherwise mistaken testimony. Thus, strong circumstantial evidence can provide a more reliable basis for a verdict. Circumstantial evidence normally requires a witness, such as the police officer who found the evidence, or an expert who examined it, to lay the foundation for its admission. This witness, sometimes known as the sponsor or the authenticating witness, is giving direct (eyewitness) testimony, and could present credibility problems in the same way that any eyewitness does. Eyewitness testimony is frequently unreliable, or subject to conflict or outright fabrication. For example, the RMS Titanic sank in the presence of approximately 700 witnesses. For many years, there was vigorous debate on whether the ship broke into two before sinking. It was not until the ship was found in September 1985 that the truth was known; however, there is often more than one logical conclusion naturally inferred from the same set of circumstances. In cases where one conclusion implies a defendant's guilt and another his innocence, the "benefit of the doubt" principle would apply. If the circumstantial evidence suggests a possibility of innocence, the prosecution has the burden of disproving that possibility.
==== Examples ==== Much of the evidence against convicted American terrorist Timothy McVeigh was circumstantial. Speaking about McVeigh's trial, Robert Precht said that "the prosecution's use of indirect evidence is no cause for worry". McVeigh was sentenced to death and subsequently executed by the US federal government, while his accomplice was sentenced to serve consecutive federal life sentences. The 2004 murder trial of Scott Peterson for the murder of his wife Laci Peterson was another high-profile conviction based heavily on circumstantial evidence, leading to Peterson's being sentenced to death. Peterson was subsequently spared execution, and in December of 2021 was re-sentenced to life in prison without the possibility of parole. Another case that relied on circumstantial evidence was that of Nelson Serrano, who received four death sentences for four first-degree murders. The 2015 murder trial of Ivan Chan Man-sum from Hong Kong was a conviction based solely on circumstantial evidence, without finding the body of his murdered girlfriend. Chan was consequently sentenced to mandatory life imprisonment. In Singapore, law student Sunny Ang was sentenced to death in 1965 solely based on circumstantial evidence when he was convicted of murdering his girlfriend during a scuba diving trip near Sisters' Islands on 27 August 1963. The victim, Jenny Cheok, was murdered for her insurance money, which amounted to $450,000. Her body has never been found. The additional absence of Cheok's body made Ang's conviction one of the landmark verdicts in Singapore, where it involved a murder conviction without a body. A famous aphorism on the probity of circumstantial evidence was penned by Henry David Thoreau, who wrote: "Some circumstantial evidence is very strong, as when you find a trout in the milk."
