The Role of Eyewitness Testimony in Criminal Cases

In criminal cases, eyewitness testimony has long been viewed as one of the most powerful forms of evidence. When someone confidently takes the stand and says, “I saw the defendant do it,” that statement can carry tremendous weight with a jury. However, as decades of research and countless real-world examples have shown, eyewitness memory is far from perfect. Mistaken identifications have led to wrongful convictions in many cases, including some of the most serious crimes.
For defendants facing criminal charges in New York, understanding the strengths and weaknesses of eyewitness testimony can make a crucial difference in how a case is defended. At Dupée & Monroe, P.C., we have extensive experience in challenging unreliable witness identifications and cross-examining witnesses to reveal inconsistencies that cast doubt on the prosecution’s version of events. If you or your family member has been arrested for a misdemeanor or felony offense in Orange County or the mid-Hudson Valley, contact our office to speak with a skilled and experienced Goshen criminal defense attorney.
The Power and Peril of Eyewitness Testimony
Eyewitness testimony can seem compelling because it feels immediate and personal. Jurors tend to trust what another person says they saw with their own eyes. Yet psychological studies have repeatedly demonstrated that human memory does not function like a video recording. Instead, it is reconstructive. Our brains fill in gaps, alter details, and reshape memories over time, often without us realizing it.
Stress, fear, lighting conditions, the presence of weapons, and even the passage of time can dramatically affect how accurately a person recalls an event. In high-pressure situations, such as violent encounters or crimes that happen quickly, witnesses often focus on a few striking details and overlook others. Later, when questioned by police, their memories can be influenced, sometimes subtly, by the way questions are phrased or by exposure to other information about the case.
How Mistaken Identifications Happen
Many wrongful conviction cases have revealed the same pattern: a sincere but mistaken witness identifies a suspect, and that identification becomes the centerpiece of the prosecution’s case. According to the Innocence Project, eyewitness misidentification was a factor in roughly 70% of wrongful convictions later overturned by DNA evidence.
Mistaken identifications often occur because of:
-
Suggestive police procedures: When law enforcement conducts a lineup or photo array, the manner in which it is organized can affect the result. If officers inadvertently signal who they believe the suspect is, or if the suspect stands out in appearance, the witness may be unduly influenced.
-
Memory contamination: Witnesses who talk to one another, see media coverage, or receive feedback from investigators may unintentionally alter their recollections to fit new information.
-
Cross-racial identification errors: Studies have shown that people often have more difficulty accurately identifying individuals of another race.
-
Stress and fear: Traumatic or high-adrenaline events can distort perception and memory.
-
Passage of time: As weeks or months go by, memory naturally fades, making later identifications less reliable.
How the Defense Can Challenge Eyewitness Testimony
At Dupée & Monroe, P.C., we carefully examine the circumstances under which eyewitness evidence was gathered. Challenging an identification doesn’t mean accusing the witness of lying; more often, it involves showing that their memory or perception may have been flawed or influenced.
Some of the most effective ways to challenge eyewitness testimony include:
1. Cross-examining the witness.
A skillful cross-examination can reveal inconsistencies in the witness’s account or highlight factors that made accurate identification unlikely. For example, questions may explore how far away the witness was, what the lighting conditions were, or how long the suspect was visible.
2. Questioning police procedures.
If the identification came from a lineup or photo array, the defense can investigate whether proper protocols were followed. New York courts recognize that suggestive identification procedures can violate a defendant’s due process rights, potentially leading to suppression of that evidence.
3. Using expert testimony.
Courts increasingly allow experts in psychology or memory science to explain to juries why eyewitness identifications can be unreliable. Expert testimony can help jurors understand the scientific reasons behind common memory errors.
4. Presenting alternative evidence.
Surveillance video, alibi witnesses, or other physical evidence can contradict a witness’s recollection and create reasonable doubt.
The Legal Framework: Identification Hearings in New York
Before trial, defense attorneys can request what’s known as a Wade hearing, named after the U.S. Supreme Court case United States v. Wade. During this hearing, the court reviews how the police conducted the identification procedure to determine whether it was fair and free of undue suggestion.
If the court finds that a lineup or photo array was improperly suggestive, the resulting identification may be excluded from evidence. Even if the identification is allowed, exposing flaws in the process can significantly weaken the prosecution’s case and influence how a jury perceives the testimony.
When Eyewitness Testimony Helps the Defense
Not all eyewitnesses testify for the prosecution. Sometimes, witnesses can corroborate the defendant’s version of events, confirming, for instance, that the defendant acted in self-defense, was misidentified, or wasn’t present at all. In these cases, the defense must still prepare carefully. The credibility of defense witnesses is just as important as that of the state’s witnesses, and their accounts must be consistent and believable.
An experienced defense lawyer ensures that supportive eyewitnesses are properly prepared for testimony and that their recollections are presented clearly and persuasively.
Building a Defense in Cases Involving Eyewitnesses
When eyewitnesses play a major role in a case, a strong defense often involves a combination of investigative work and legal strategy. Defense attorneys can interview witnesses independently, locate additional witnesses who may offer different perspectives, and obtain surveillance footage or records that contradict the prosecution’s timeline.
