On Nova - Forensics on Trial

Airing October 17 - Check your local listings

Program Description

There is a startling gap between the glamorous television world of “CSI” and the gritty reality of the forensic crime lab. With few established scientific standards, no central oversight, and poor regulation of examiners, forensics in the U.S. is in a state of crisis. In "Forensics on Trial", NOVA investigates how modern forensics, including the analysis of fingerprints, bite marks, ballistics, hair, and tool marks, can send innocent men and women to prison—and sometimes even to death row. Shockingly, of more than 250 inmates exonerated by DNA testing over the last decade, more than 50 percent of the wrongful convictions stemmed from invalid or improperly handled forensic science. With the help of vivid recreations of actual trials and cases, NOVA will investigate today’s shaky state of crime science as well as cutting-edge solutions that could help investigators put the real criminals behind bars.

Justice Department to review forensic evidence used in thousands of cases - Washington Post

The Justice Department and the FBI have launched a review of thousands of criminal cases to determine whether any defendants were wrongly convicted or deserve a new trial because of flawed forensic evidence, officials said Tuesday.

The undertaking is the largest post-conviction review ever done by the FBI. It will include cases conducted by all FBI Laboratory hair and fiber examiners since at least 1985 and may reach earlier if records are available, people familiar with the process said. Such FBI examinations have taken place in federal and local cases across the country, often in violent crimes, such as rape, murder and robbery.

The review comes after The Washington Post reported in April that Justice Department officials had known for years that flawed forensic work might have led to the convictions of potentially innocent people but had not performed a thorough review of the cases. In addition, prosecutors did not notify defendants or their attorneys even in many cases they knew were troubled.

Gunshot Residue Analysis

Gunshot residue is actually a compound containing either two or three particles commonly found in gunshot residue or primer residue.  Examiners will say that particles with  lead, antimony and barium present are indicative of gunshot residue while particles with two of the three particles are consistent with primer residue.  The report issued by Hamilton County’s laboratory will state that two element particles “are found in primer residue, but also may originate from other sources.”  For this reason, the use of gunshot residue is no longer accepted by many crime scene laboratories and forensic scientists.[1]

The possibility of transfer of particles resulting in the contamination of the hands or clothes tested creates another area for challenge.  All particles containing lead, antimony, or barium are very large.  Additionally, these particles persist almost indefinitely.  Furthermore, because the particles are rather large, they can easily transfer from hands, firearms, and furniture to clothing.[2]  If particles consistent with gunshot residue are found on hands, it indicates the person (a) had discharged a firearm, (b) had been near a discharged firearm, or (c) had come into contact with something that had gunshot residue on it.  If particles are found on clothing, it indicates that the item (a) had been worn while a person discharged a firearm, (b) had been near a discharged firearm, or (c) had come into contact with something that had gunshot residue on it.

Forensic Practitioners' Credentials Come Under Fire

Through a joint project of PBS’ Frontline, ProPublica and the UC Berkeley School of Journalism, a Berkeley graduate student in journalism discovered that she was able to receive certification as a forensic consultant from the American College of Forensic Examiners International (ACFEI) after taking a single, open-book, multiple-choice exam online.


Several former ACFEI employees call the group a mill designed to churn out and sell as many certificates as possible. They say applicants receive cursory, if any, background checks and that virtually everyone passes the group’s certification exams as long as their payments clear.

  Some forensic professionals say the organization’s willingness to hand out credentials diminishes the integrity of the field.

The joint project, which investigates several shortcomings of the forensic science system, follows a landmark 2009 National Academy of Sciences report that challenged the scientific basis and rigor of forensics. The report’s chief recommendation, that a national entity to establish and enforce higher standards in the forensic sciences, has not yet been implemented.

Latent Print Examination and Human Factors: Improving the Practice through a Systems Approach

Fingerprints have provided a valuable method of personal identification in forensic science and criminal investigations for more than 100 years. The examination of fingerprints left at crime scenes, generally referred to as latent prints, consists of a series of steps involving a comparison of the latent print to a known (or exemplar) print.

In addition to reaching correct conclusions in the matching process, latent print examiners are expected to produce records of the examination and, in some cases, to present their conclusions and the reasoning behind them in the courtroom. In recent years, the accuracy of latent print identification has been the subject of increased study, scrutiny, and commentary in the legal system and the forensic science literature. In December 2008, the U.S. National Institute of Standards and Technology

(NIST) convened The Expert Working Group on Human Factors in Latent Print Analysis to conduct a scientific assessment of the effects of human factors on forensic latent print analysis and to develop recommendations to reduce the risk of error. This report documents their findings and recommendations, addressing issues ranging from the acquisition of impressions of friction ridge skin to courtroom testimony, from laboratory design and equipment to research into emerging methods for associating latent prints with exemplars. It provides a comprehensive discussion of how human factors relate to all aspects of latent print examinations including communicating conclusions to all relevant parties through reports and testimony.

ABA Resolution regarding expert testimony

Urges Judges’ Consideration Presenting Expert Testimony to Jurors

RESOLVED, That the American Bar Association urges judges and lawyers to consider the following factors in determining the manner in which expert testimony should be presented to a jury and in  instructing the jury in its evaluation of expert scientific testimony in criminal and delinquency proceedings:

1.      Whether experts can identify and explain the theoretical and factual basis for any opinion given in their testimony and the reasoning upon which the opinion is based.

2.      Whether experts use clear and consistent terminology in presenting their opinions.

3.      Whether experts present their testimony in a manner that accurately and fairly conveys the significance of their conclusions, including any relevant limitations of the methodology used.

4.      Whether experts explain the reliability of evidence and fairly address problems with evidence including relevant evidence of laboratory error, contamination, or sample mishandling.

5.      Whether expert testimony of individuality or uniqueness is based on valid scientific research.

6.      Whether the court should prohibit the parties from tendering witnesses as experts and should refrain from declaring witnesses to be experts in the presence of the jury.

7.      Whether to include in jury instructions additional specific factors that might be especially important to a jury’s ability to fairly assess the reliability of and weight to be given expert testimony on particular issues in the case.

Featured Case - Lukjan

Court of Appeals, 2010-CA-001509-MR

Susan Lukjan v. Commonwealth

Audra J. Eckerle, Judge, Jefferson County

To be Published Opinion, Reversing and Remanding

** ** ** ** **

Before: Taylor, Chief Judge; Acree and Vanmeter, Judges.

Opinion by Judge Acree

Lukjan was convicted of arson, burning personal property to defraud an insurer, and committing a fraudulent insurance act over $300, and sentenced to twelve years.  The COA reversed the conviction, and remanded for a new trial. Lukjan was denied a defense when the circuit court refused to allow the defense arson expert to testify on the ground that he wasn’t a licensed investigator as required by KRS 329A.015 and KRS 329A.010 (prohibiting an individual from holding himself out to the public as a private investigator).  On remand, the circuit court must judge Lukjan’s proffered experts based on KRE 702 and caselaw. Under those standards, licensure is not necessary to qualify as an expert, though it may be a factor. See Fugate v. Commonwealth, 993 S.W.2d 931 at 935.

 The COA also reversed the circuit court’s decision to admit the prosecution’s arson opinion evidence without either an adequate Daubert hearing, specifically without examining “the portions of the record which would have enabled the court to determine the reliability and relevance of the evidence.”

Practice note:    Consider carefully what is contained in the “certified business record” you are trying to get admitted.  The COA held that a lightning strike report wasn’t admissible as a business record under KRE 902(11), because the certification said the data was “detected and recorded by National Lightning Detection Network Sensors, and processed by “[h]ighly refined algorithms[.]”  The COA held the proffered report appeared to be scientific evidence whose admissibility is governed by KRE 702 and not a business record “as contemplated by KRE 803(6) and KRE 902(11).”  If the record you are trying to get admitted was not made by a human being, you may need to subpoena the custodian.

Spark of Truth: Can Science Bring Justice to Arson Trials? - Discover Magazine

Gregory Gorbett/Eastern Kentucky University

Also see the related article, "Seven Myths About Arson."

On a rainy spring morning in eastern Kentucky, Greg Gorbett prepares to commit arson. His target is a tidy but cheerless one-bedroom apartment with the kind of mauve-colored carpet, couches, tables, and lamps you would find in a cheap motel. Gorbett is not the only one eager to see the place burn. A handful of other fire scientists and grad students from Eastern Kentucky University (EKU) are checking equipment in the test room as well. They have gathered at the EKU fire lab, a concrete structure in an open meadow as close to nowhere as possible, to document in exacting detail the life cycle of a blaze.

Gorbett scans the setup one last time. A foil-covered wire studded with metal probes—a thermocouple array—crosses the ceiling and hangs down the center of the space; it will measure the temperature at one-foot intervals every two seconds. A radiometer shaped like a soup can will detect changes in radiant energy. Bundles of yellow wires will carry the data to a computer-equipped truck sitting out back. There is also a man lying on the floor: James Pharr, a former fire investigator from Charlotte, North Carolina, wearing a fire-resistant suit and oxygen mask, who will record the event with a thermal-
imaging camera.

Featured Case - Hurt - Improper Expert Testimony

Paul Hurt v. Commonwealth, 10-CA-343-MR, unpublished. 

While unpublished, this is an important case for two reasons.  Hurt was convicted of several counts of sodomy and sexual abuse against his step-daughter.  Even though there were no physical evidence of any abuse, the jury still convicted him based in part on the testimony of Dr. Sally Perlman.  Dr. Perlman examined the step-daughter after her allegations of sexual abuse and concluded there were no findings of sexual abuse.  However, Dr. Perlman was able to testify that the step-daughter, during the exam, laid “there like a wet noodle.”  Because the child was so relaxed during the examination, Dr. Perlman testified that she believed the child had been sexually abused.  According to the Kentucky Supreme Court, Dr. Perlman’s testimony should not have been allowed - it is improper to admit "evidence of a child’s behavioral symptoms or traits as indicative of sexual abuse . . . on grounds that this is not a generally accepted medical concept.”  Bell v. Commonwealth, 245 S.W.3d 738, 745 (Ky. 2008), overruled on other grounds by Harp v. Commonwealth, 266 S.W.3d 813 (Ky. 2008)." 

Because testimony that a child’s relaxed behavior was consistent with that of a child who had been sexually abused was inadmissible, trial counsel performed deficiently in failing to object to this testimony.  The Court of Appeals did not reverse Hurt’s conviction due to the Court’s belief that the detailed nature of the step-daughter’s testimony would not have changed the trial outcome, i.e., there was no prejudice.  Even so, chances of a defendant winning at trial should be improved by keep this inadmissible evidence out. 

Practice Tips:  1) use a Daubert hearing to prevent this type of behavioral expert from coming in; and 2) object if  “wet noodle” evidence does come in.
