AAAS Report on Fire Investigation

Attorneys who are handling cases involving arson allegations should be aware of the Forensic Science Assessments: A Quality and Gap Analysis – Fire Investigation publication that was released this month (July 2017). The report was produced by the American Association for the Advancement of Science (AAAS).

The report looks at the discipline of fire investigations and identifies which parts are well founded in science and where gaps in knowledge exist. The report identifies 25 areas in need of additional research. The report is divided into the topics of fire scene investigation and fire debris analysis. The report concludes that canine alerts should not be relied upon unless confirmed by laboratory analysis (pp. 7, 18, 30). The report notes that some research has found erroneous conclusions about point of origin in excess of 75% (p. 5 of plain language version). Additional research regarding error rates is needed. (pp. 7-8). The report also contains an in-depth discussion of cognitive bias, the role it plays in fire investigation, and recommendations for minimizing bias in fire scene investigation (p. 8, 13, 26).

The full report is available for free download. A “plain language” summary version is also available.

The report is the result of a Working Group consisting of an academic fire engineer, an analytical chemist, a cognitive psychologist, and a forensic practitioner. The work was guided by an Advisory Committee which included a law enforcement official, a social scientist, a cognitive psychologist, a law professor, a judge, a biomedical researcher, a forensic scientist, and a statistician.

Forensic Evidence Errors in Arson Investigations and Crime Scene Processing

Paul Bieber (Director at Arson Research Project: explores the misidentification of an accidental fire as an act of arson and how unreliable, quasi-scientific techniques led to the mistaken execution of an innocent man.

Improving Arson Investigations

Discover Magazine recently published two articles about how recent scientific investigation has challenged the traditional principles and methodology of fire investigation. Spark of Truth: Can Science Bring Justice to Arson Trials? explains how these developments have occurred and Seven Myths About Arson debunks seven fire scene findings that have been used in numerous cases as evidence of arson.

In light of these articles being published and the recommendations of the Texas Forensic Science Commission discussed below, I have updated the Arson Resources page of the IDS forensics website with several new articles and resources. Take a look at the changes I have made!

On October 28, 2011, the Texas Forensic Science Commission recommended a review of arson convictions in the state to determine whether faulty science could have led to wrongful convictions. The State Fire Marshal’s Office and the Innocence Project of Texas will assist in the review.

Click here to read the Commission’s recommendations or visit the Innocence Project’s website for more information on the recommendations and the Cameron Todd Willingham case.
