U.S. reviewing 27 death penalty convictions for FBI forensic testimony errors


An unprecedented federal review of old criminal cases has uncovered as many as 27 death penalty convictions in which FBI forensic experts may have mistakenly linked defendants to crimes with exaggerated scientific testimony, U.S. officials said.

The review led to an 11th-hour stay of execution in Mississippi in May.

Independent scientists critique suspect forensic work

It is not known how many of the cases involve errors, how many led to wrongful convictions or how many mistakes may now jeopardize valid convictions. Those questions will be explored as the review continues.

The discovery of the more than two dozen capital cases promises that the examination could become a factor in the debate over the death penalty. Some opponents have long held that the execution of a person confirmed to be innocent would crystallize doubts about capital punishment. But if DNA or other testing confirms all convictions, it would strengthen proponents’ arguments that the system works.

FBI officials discussed the review’s scope as they prepare to disclose its first results later this summer. The death row cases are among the first 120 convictions identified as potentially problematic among more than 21,700 FBI Laboratory files being examined. The review was announced last July by the FBI and the Justice Department, in consultation with the Innocence Project and the National Association of Criminal Defense Lawyers (NACDL).

The unusual collaboration came after The Washington Post reported last year that authorities had known for years that flawed forensic work by FBI hair examiners may have led to convictions of potentially innocent people, but officials had not aggressively investigated problems or notified defendants.

At issue is a once-widespread practice by which some FBI experts exaggerated the significance of “matches” drawn from microscopic analysis of hair found at crime scenes.

Since at least the 1970s, written FBI Laboratory reports typically stated that a hair association could not be used as positive identification. However, on the witness stand, several agents for years went beyond the science and testified that their hair analysis was a near-certain match.

The new review listed examples of scientifically invalid testimony, including claiming to associate a hair with a single person “to the exclusion of all others,” or to state or suggest a probability for such a match from past casework.

Whatever the findings of the review, the initiative is pushing state and local labs to take similar measures.

For instance, the Texas Forensic Science Commission on Friday directed all labs under its jurisdiction to take the first step to scrutinize hair cases, in a state that has executed more defendants than any other since 1982.

Separately, FBI officials said their intention is to review and disclose problems in capital cases even after a defendant has been executed.

“We didn’t do this to be a model for anyone — other than when there’s a problem, you have to face it, and you have to figure how to fix it, move forward and make sure it doesn’t happen again,” FBI general counsel Andrew Weissmann said. “That tone and approach is set from the very top of this building,” he said, referring to FBI Director Robert S. Mueller III.David Christian “Chris” Hassell, director of the FBI Laboratory, said the review will be used to improve lab training, testimony, audit systems and research, as it has done when previous breakdowns were uncovered. The lab overhauled scientific practices when whistleblowers revealed problems in 1996 and again after an FBI fingerprint misidentification in a high-profile 2003 terrorism case, he said.

“One of the things good scientists do is question their assumptions. No matter what the field, what the discipline, those questions should be up for debate,” Hassell said. “That’s as true in forensics as anything else.”

Advocates for defendants and the wrongly convicted called the undertaking a watershed moment in police and prosecutorial agencies’ willingness to re-open old cases because of scientific errors uncovered by DNA testing.

Peter J. Neufeld, co-founder of the Innocence Project, which supports inmates who seek exoneration through DNA testing, applauded the FBI, calling the review historic and a “major step forward to improve the criminal justice system and the rigor of forensic science in the United States.”

Norman L. Reimer, executive director of the NACDL, also praised the effort, predicting that it would have “an enormous impact on the states” and calling on the defense bar to represent indigent convicts.

“That’s going to be a very big job as this unfolds,” said Reimer, whose group has spent 1,500 hours identifying cases for the second round of review.

Under terms finalized with the groups last month, the Justice Department will notify prosecutors and convicted defendants or defense attorneys if an internal review panel or the two external groups find that FBI examiners “exceeded the limits of science” when they claimed to link crime scene hair to defendants in reports or testimony.

If so, the department will assist the class of prisoners in unprecedented ways, including waiving statutes of limitations and other federal rules that since 1996 have restricted post-conviction appeals. The FBI also will test DNA evidence if sought by a judge or prosecutor.

The review will prioritize capital cases, then cases in which defendants are imprisoned.

Unlike DNA analysis, there is no accepted research on how often hair from different people may appear the same.

The federal inquiry came after the Public Defender Service helped exonerate three D.C. men through DNA testing that showed that three FBI hair examiners contributed to their wrongful convictions for rape or murder in the early 1980s.

The response has been notable for the department and the FBI, which in the past has been accused of overprotecting its agents. Twice since 1996, authorities conducted case reviews largely in secret after the scientific integrity of the FBI Lab was faulted.

Weissmann said that although earlier reviews lawfully gave prosecutors discretion to decide when to turn over potentially exculpatory material to the defense, greater transparency will “lessen skepticism” about the government’s motives. It also will be cheaper, faster and more effective because private parties can help track down decades-old cases.

Scientific errors “are not owned by one side,” he said. “This gives the same information to both sides, and they can litigate it.”

The review terms could have wide repercussions. The FBI is examining more than 21,000 federal and state cases referred to the FBI Lab’s hair unit from 1982 through 1999 — by which time DNA testing of hair was routine — and the bureau has asked for help in finding cases before lab files were computerized in 1985.

Of 15,000 files reviewed to date, the FBI said a hair association was declared in about 2,100 cases. Investigators have contacted police and prosecutors in more than 1,200 of those cases to find out whether hair evidence was used in a conviction, in which case trial transcripts will be sought. However, 400 of those cases have been closed because prosecutors did not respond.

On May 7, Mississippi’s Supreme Court stayed the execution of Willie Jerome Manning for a 1992 double homicide hours before he was set to die by lethal injection.

FBI cases may represent only the tip of the problem.

While the FBI employed 27 hair examiners during the period under review, FBI officials confirmed for the first time this week that records indicate that about 500 people attended one-week hair comparison classes given by FBI examiners between 1979 and 2009. Nearly all of them came from state and local labs.

State and local prosecutors handle more than 95 percent of violent crimes.

In April, the accreditation arm of the American Society of Crime Laboratory Directors declined to order state and local labs to conduct reviews, but issued a public notice recommending that each laboratory evaluate the impact of improper statements on past convictions, reminding them of their ethical obligation to act in case of a potential miscarriage of justice.

FBI Lab officials say they have not been contacted by other labs about their review or who completed the FBI classes.

Va. DNA data support innocence of 33 convicted of sex crimes, study concludes


June 18, 2012 Source : http://www2.timesdispatch.com

RICHMOND, Va. —

Data from Virginia’s post-conviction DNA project support the innocence of 33 persons convicted of sexual assaults from 1973 to 1987 concludes an Urban Institute study.

Findings released today indicate more people remain to be cleared by the Virginia project, a groundbreaking effort aimed at identifying persons wrongfully convicted in the 15 years before DNA testing was widely available.

The institute estimates a wrongful conviction rate in sexual assault cases of between 8 to 15 percent, comparable with the results in sample testing that exonerated two people and prompted then-Gov. Mark R. Warner to order the full Virginia project in 2005.

Jon Gould, director, of the Washington Institute for Public and International Affairs Research at American University, said “This is the most methodologically sound study that’s been done and the rate is much higher than has been shown in other studies.”

An acknowledged weakness in the institute’s report is that the contract for the study expired before researchers could get to courthouses to review the old trial files to better determine the context and significance of the DNA results.

The institute said available information on the cases was limited to data in the old state forensic files, which mainly included basic facts about the crime and the results of the original forensic tests and the results of more recent DNA analysis.

Rockne Harmon, a former California district attorney and DNA expert, said that is a problem. He said the institute should have at least done a representative sampling of the old court files.

Among other things, rape victims are frequently asked if they had consensual sex within 72 hours of an assault. “Without this (kind of) information little can be said about the materiality of finding a matching or non-matching DNA profile,” said Harmon.

However, John Roman, the lead researcher in the project, said that even if all the court records were reviewed he would not expect many of the 33 cases to drop out.

Weaknesses or not, Steven D. Benjamin, a member of the Virginia Board of Forensic Science and president elect of the National Association of Criminal Defense Lawyers, said the study should set off alarm bells.

“Each defendant in the cases that support innocence should be interviewed immediately, and the case investigated thoroughly,” he said. “If any one of these 33 is innocent, each day . . . is an injustice,” said Benjamin.

The Urban Institute cannot reveal any of the identities, though many of those cases may be made public after July 1 due to recent state legislation ordering the department to release test results in cases where the convicted person’s DNA was not found.

Nearly 800 cases involving 1,100 convicted persons have been tested in the Virginia project since 2005 but only three more people have been exonerated in addition to the two cleared in sample testing seven years ago.

The Urban Institute says the Virginia data – DNA results in a random sample of suspects convicted of rape, murder and other serious crimes — is better suited for such studies on wrongful conviction rates than data in earlier studies.

“This ‘test-them-all’ approach to post-conviction DNA testing has never been replicated by any other state,” says the report.

The Virginia Department of Forensic Science said last month that testing failed to identify, or excluded, the DNA of 78 convicted defendants more than a dozen of them now dead and others not yet located.

Absence of DNA in the 78 cases can be consistent with innocence but may prove nothing. Much depends on context. Failure to find a suspect’s DNA in a cigarette butt at the scene of a rape may be irrelevant — but failure their DNA in semen can be telling.

Though unable to review old courthouse files, the institute said the Virginia data, “likely provide the best opportunity to date to understand the rate of wrongful conviction.”

“Whether the true rate of potential wrongful conviction is 8 percent or 15 percent . . . is not as important as the finding that these results require a strong and coordinated policy response,” concludes the institute report.

Brandon Garrett, a University of Virginia School of Law professor, also thinks the study needs a strong response from policy makers. “I think this report isn’t the final report, it’s just the beginning,” he said.

“There’s still a lot of (work) to do and a lot of questions that need to be answered,” said Garrett.

The Virginia Department of Forensic Science does not determine the legal significance of test results and forwarded them to local authorities where the crimes took place.

But aside from the five exonerations and several other cases, little is known of the other exclusion cases.

Critics of the Virginia effort such as Benjamin and Peter Neufeld, a cofounder of the Innocence Project, want to allow defense lawyers access to project results along with police and prosecutors.

They also urge that cases of possible wrongful convictions be pursued even where the convicted person is dead to clear their name, to make sure the guilty person is off the street and to learn what led to the wrongful conviction to help prevent future ones.

The Virginia Department of Forensic Science and the Board of Forensic Science, which considers the DNA test results criminal records, have long resisted efforts to reveal them to anyone other than law enforcement.

The convicted people were not going to be told about the testing until 2008 when the General Assembly used a budget amendment and directed they be notified.

This year the General Assembly, concerned that potential exonerations were not being adequately investigated, directed the department, effective July 1, to release the test results in cases where testing failed to find the convicted person’s DNA.

The legislators’ concern stemmed from the case of Bennett S. Barbour, of Charles City County, who was wrongly convicted of a 1978 rape in Williamsburg and was one of the people excluded by testing who could not be initially found by mail.

Testing in June 2010 cleared him and implicated a convicted rapist who will be tried for the crime in August. Barbour did not learn about the DNA testing until 18 months later when a volunteer lawyer tracked him down via telephone.

Garrett, of the University of Virginia School of Law, who urges more work be done, said, “Time will tell how many more of these cases, like Barbour’s, will result in full exonerations. Hopefully that process is moving more smoothly now.”

Methodology

Here is how the study was conducted:

The Justice Policy Center of the Urban Institute studied the test results in 634 of the Virginia cases involving 715 convicted people from 94 Virginia localities under the terms of a $4.5 million federal grant that paid for most, but not all, of the state testing.

Of the 634 cases, 422 were for sexual assault. In 227 of those cases, testing results were sufficient to either implicate or fail to find the convicted person’s DNA. And the institute believes that the testing in 33 of the exclusion cases supports innocence.

Comparing the 33 with all 422 sexual assault convictions yields an 8 percent wrongful conviction rate while comparing it to just the 227 cases where testing either implicated the convicted person or failed to find his or her DNA yields a 15 percent rate.

In 2005 the initial state sample testing of 31 cases resulted in 16 cases where the convicted person’s DNA was either identified or excluded and exonerated two men of rapes.

Comparing the two exonerations to the 31 cases yields a wrongful conviction rate of 6 to 7 percent while comparing the exonerations to the 16 cases with determinative results yields a rate of 12 to 13 percent.

According to the Urban Institute, the Justice Policy Center conducts nonpartisan research and evaluation designed to improve justice and public safety policies and practices at the national, state and local level.
