When most people think of criminal convictions, they think of criminal cases where there was a lot of direct evidence linking the defendant to the crime. However, in some cases, defendants can be convicted based on circumstantial evidence alone. This means that the Crown Prosecution and Police do not have any physical evidence connecting the defendant to the crime, but rather they are relying on evidence such as witness testimony and circumstantial clues to argue that the defendant is guilty.
In order to find an accused person guilty in a circumstantial evidence case, the Judge or Jury must be satisfied beyond a reasonable doubt that the only rational inference that can be drawn from the circumstantial evidence is that the accused is guilty.
Circumstantial evidence is not to be evaluated piece by piece during a criminal trial but rather cumulatively.
Circumstantial evidence is sometimes misunderstood as being less credible than direct evidence. However, some of the most compelling types of forensic evidence, such as fingerprint evidence, DNA analysis evidence, and blood splatter evidence, are circumstantial.
Circumstantial VS Direct Evidence
Direct evidence directly links a person to the accused criminal activity. This may come from sources such as the victim, eyewitness testimony, and security footage.
As an example, seeing a person walking their dog is direct evidence of them walking their dog.
Circumstantial evidence provides evidence that could infer the person is linked to the accused activity. This can come from a variety of sources, including witnesses who didn’t directly see the crime, expert witnesses, and forensic analysis.
For example, seeing someone putting on their jacket and picking up a dog leash would allow you to infer that the person is about to walk their dog. Even though you do not directly see the person walk their dog, from the information available it is the most likely inference.
Examples of Circumstantial Evidence
Fingerprints or DNA at a crime scene – Its circumstantial evidence unless there is direct evidence linking that person to the crime scene at the time of the crime.
Possession of Property – an item taken during the commission of an offence is evidence that is linked to the crime, but does not mean that the person in possession committed the crime.
Circumstantial as Corroborating Evidence
Because circumstantial evidence requires inference, it is not always as strong in proving guilt beyond a reasonable doubt on its own. Instead, it is often best served as corroborating evidence. It may be used in conjunction with multiple instances of circumstantial evidence to create a strong inference, and/or to corroborate direct evidence.
In corroborating evidence from a witness, circumstantial can be an especially valuable type of evidence. For instance, eyewitness testimony is often unreliable because of the trauma that occurs from the incident. This is especially true where the witness is also the victim. The extreme stress of the situation can lead to making mistakes that can lead to identifying the wrong person or misremembering events.
In the event of a victim as the witness, circumstantial evidence from witnesses not directly engaged in the crime can help to confirm the direct evidence. Although a circumstantial witness may not have seen the direct events, they may be more reliable as they were under less stress.
Take an armed robbery as an example:
The victim, who experienced the robbery is the leading witness and provides direct evidence. Being the victim of an armed robbery, however, results in a high level of trauma. As a result, this stress may affect their reliability as a witness.
People outside the store may be used to corroborate, although the evidence they witnessed was circumstantial. For instance, if they witnessed a person fleeing after the event occurred or acting suspiciously beforehand this evidence could be relevant. Their testimony could strengthen or weaken the direct evidence depending on their reliability and similarities.
Can You be Convicted on Circumstantial Evidence Alone?
It is possible but more difficult, to convict a person on circumstantial evidence alone. Direct evidence simply is not available for every crime. If there is only circumstantial, the Crown must reasonably satisfy that guilt is the only reasonable assumption based on the evidence available.
In this event, a criminal defence lawyer challenges evidence where applicable. The criminal lawyer examines whether the circumstantial evidence is relevant, reliable, and sufficient. Was the evidence collected and applied legally? Did police follow proper protocol for interviewing witnesses, or could their testimony have been led or coached? Were witnesses excluded who would refute the Crown’s evidence?
Circumstantial evidence can also be used to the defendant’s advantage. For example, a circumstantial witness may identify a different person than the direct witness, calling their testimony or reliability into question.
As well, texts, receipts, and witnesses could corroborate the defendant’s alibi. Inferring that they were at a different location, or otherwise engaged, at the time of the offence.
