Why eyewitnesses get it wrong - Scott Fraser

Summary

In 1991, a father was murdered in Lynwood, California, and a teenager, Francisco CIO, was quickly convicted based on eyewitness accounts. Despite no physical evidence and CIO's alibi, he was sentenced to life. Years later, a forensic neurophysiologist's examination of the case revealed the fallibility of eyewitness memory and poor lighting conditions at the crime scene, leading to a retrial and CIO's release. This case underscores the importance of integrating science into the legal system and the caution needed in relying on memory.

Q & A

What was the date and location of the murder mentioned in the script?

The murder occurred on January 18th, 1991, in a small bedroom community of Lynwood, California, which is a few miles southeast of Los Angeles.

Who was identified as the suspect in the murder case?

Francisco CIO, a 17-year-old kid who lived about two or three blocks away from where the shooting occurred, was identified as the suspect.

How quickly did the police identify the suspect after the shooting?

The police identified Francisco CIO as the suspect in less than 24 hours after the shooting.

What was the outcome of Francisco CIO's trial based on the initial investigation?

Francisco CIO was convicted of first-degree murder and sentenced to life imprisonment based on the initial investigation and testimonies from the teenagers who identified him.

Why was Francisco CIO's case reconsidered for a retrial?

The case was reconsidered for a retrial due to decades of scientific research indicating the fallibility of human memory and eyewitness identifications, as well as the lack of physical evidence such as the murder weapon or the identification of the shooter's vehicle.

What is the significance of the Innocence Project's work in the context of this case?

The Innocence Project's work highlights the issue of wrongful convictions based on eyewitness identifications, which is relevant to Francisco CIO's case since his conviction was primarily based on such testimonies.

How does the concept of 'the brain abhors a vacuum' relate to the case?

The concept refers to the brain's tendency to fill in missing information from memory, which can lead to reconstructed memories. This is significant in the case as it questions the reliability of the teenagers' identifications of Francisco CIO.

What role did the forensic neurophysiologist play in the retrial petition?

The forensic neurophysiologist provided expertise on eyewitness memory and identification, and also on human night vision, which was crucial to analyze the lighting conditions at the time of the crime, casting doubt on the reliability of the identifications made under those conditions.

What was the lighting condition during the crime according to the teenagers and the police?

Both the investigating officers and the teenagers testified that the lighting was good at the crime scene during the shooting.

How did the forensic neurophysiologist challenge the claimed lighting conditions at the crime scene?

The forensic neurophysiologist conducted a scene reconstruction with photometers and other measures of illumination and color perception, demonstrating that the lighting was, in fact, poor, which contradicted the testimonies and raised questions about the accuracy of the identifications.

What was the judge's reaction to the reenactment of the crime scene, and what was the outcome?

After the reenactment, which showed the poor lighting conditions and the impossibility of accurate identification, the judge granted the petition for a retrial and released Francisco CIO to aid in the preparation of his defense. The prosecution later decided not to retry him.

What broader implications does this case have for the integration of science in the courtroom?

The case highlights the need for more scientific rigor in the courtroom, suggesting that law schools should incorporate more science, technology, engineering, and mathematics (STEM) education to prepare future judges and legal professionals to better understand and apply scientific evidence.
