Kirk Odom was convicted of a 1981 rape and robbery after a woman identified him as her attacker and an FBI specialist testified that hair on her nightgown was consistent with hair on Odom's head.
But DNA testing some 30 years later affirmed what Odom long had maintained: The hair wasn't his; neither was the semen left on a pillowcase and robe. A felony conviction that imprisoned him for decades was overturned in 2012 by a judge who declared it a "grave miscarriage of justice."
"I was hoping that I was going to go home that day," Odom, recalling his trial in Washington, D.C., said in an interview. Instead, "they sentenced me to 20 to 66 years in prison."
His experience is but one example of flawed forensic science from the pre-DNA era, a simmering problem that now appears far more widespread than initially thought. The Innocence Project, which works to exonerate the wrongly accused, has identified 74 overturned convictions in which faulty hair evidence was a factor. Now, a new disclosure by the FBI that experts gave erroneous testimony on hair analysis in more than 250 trials before 2000 suggests that number could rise dramatically.
Defense lawyers say the latest revelations — on top of established concerns about bite mark identification and arson science — confirm fears about the shortcomings of old-fashioned forensic techniques and could affect thousands of cases. Advancing technologies have put such techniques under more scrutiny, including from judges, and highlighted the limits of once-established practices.
"There are forces converging at the moment that are finally bringing some recognition to the failings of many venerable techniques," said Chris Fabricant, director of strategic litigation at the Innocence Project.
A 2013 Associated Press investigation concluded that at least 24 men convicted or charged with murder or rape based on bite mark evidence — the practice of matching teeth to a flesh wound — were exonerated since 2000. Some high-profile criminal cases involving arson science have come under renewed scrutiny amid debunked fire investigations. Last year, a Pennsylvania judge threw out the conviction of a Korean immigrant who had spent 24 years in prison for his daughter's death.

The Justice Department in 2012 embarked on a review of more than 2,000 criminal cases following high-profile exonerations in which microscopic hair analysis was used.
The government provided an astonishing update last month when it revealed that of the 268 trials reviewed as of mid-March, investigators found erroneous statements from FBI experts in nearly all of the cases — including in death-penalty prosecutions. The review is limited to cases dating before 2000 in which FBI examiners provided evidence. But the number of affected cases would almost certainly be much higher if the review took into account cases involving FBI-trained state examiners.
Still, no one knows how many defendants have been wrongly convicted because the existence of flawed testimony — often just one element of a prosecution — does not establish innocence.
"What it does mean is that those cases need to be looked at very closely to see what role hair played in the case," said Norman Reimer, executive director of the National Association of Criminal Defense Lawyers.

Odom, 52, always maintained his innocence, saying he did not know the woman and was not at her apartment when the assault occurred. But the hair evidence and eyewitness identification proved persuasive, and Odom spent more than 20 years in prison before being released on parole in 2003.
The big break came when the public defender's office in Washington reopened Odom's case following the earlier exoneration of another local man because of faulty hair evidence.
DNA testing on evidence pulled from storage showed that the hair on the woman's garment could not have come from Odom. The conviction was thrown out — a relief for a man who had been a registered sex offender and whose travel had been hampered.
When the call came that he'd been cleared, Odom was on a nighttime plumbing job, "and I just yelled out in happiness. It was a very joyful moment."
