Kevin Martin’s exoneration in Washington, D.C., this week, as reported here, proved once again that FBI hair analysis is flawed and inaccurate. Martin was the fifth person to have his conviction overturned because of inaccurate hair analysis by FBI agents. That bodes well for others convicted on such evidence where, as in Martin’s case, biological evidence still exists that can be subjected to DNA testing.
But what about those cases in which there is no evidence to test? Will prosecutors still defend cases that were greatly based on FBI hair comparisons even after the FBI conceded in 2013 that microscopic hair analysis was not based on sound science?
The Massachusetts case of George Perrot is a good example of a case with great merit despite the lack of DNA. Perrot has been incarcerated for almost 29 years for a 1985 rape of elderly woman in Springfield greatly because of the testimony of an FBI agent that a single hair found on the victim’s bed matched a known sample of Perrot’s hair.
Perrot, who was only 17 at the time, has insisted on his innocence ever since his arrest. In 2001, his conviction was overturned because of numerous prosecutorial errors, but the conviction was reinstated by a higher court because of the supposed strength of the microscopic hair evidence used against him.
Never mind that the rape didn’t occur on the bed where the hair was found. Never mind that the victim repeatedly refused to identify Perrot as the rapist because, she stated, the rapist was clean-shaven and had short hair and Perrot had shaggy hair and a beard. Never mind that the series of rapes of elderly women in which Perrot was the purported perpetrator continued after his arrest. The hair “match,” the court said, was more important.
In a motion filed earlier this month, Perrot’s pro bono attorneys from the Ropes & Gray law firm, argue that the FBI’s acknowledgment that its examiners provided scientifically unsupported testimony justifies a new trial for Perrot.
Unfortunately, the attorneys could not locate the biological evidence in the case for DNA testing to bolster Perrot’s innocence claim the way Kevin Martin’s attorneys were able to. There are dozens of people like Perrot out there convicted with hair-comparison testimony who can’t use DNA testing to prove the testimony wrong.
That doesn’t make them any less innocent, but prosecutors and the courts may not see it that way. Of the 106 convictions in the 1980s and 1990s in the District of Columbia that included an FBI hair match that have thus far been reviewed, prosecutors said only Martin’s supported a “viable” claim for innocence. If it hadn’t been for DNA, Martin’s claim probably wouldn’t have viewed as viable at all.
