The Washington Post July 29 2014: Federal review stalled after finding forensic errors by FBI lab unit spanned two decades.

Nearly every criminal case reviewed by the FBI and the Justice Department as part of a massive investigation started in 2012 of problems at the FBI lab has included flawed forensic testimony from the agency, government officials said.

The findings troubled the bureau, and it stopped the review of convictions last August. Case reviews resumed this month at the order of the Justice Department, the officials said.

U.S. officials began the inquiry after The Washington Post reported two years ago that flawed forensic evidence involving microscopic hair matches might have led to the convictions of hundreds of potentially innocent people. Most of those defendants never were told of the problems in their cases.

The inquiry includes 2,600 convictions and 45 death-row cases from the 1980s and 1990s in which the FBI’s hair and fiber unit reported a match to a crime-scene sample before DNA testing of hair became common. The FBI had reviewed about 160 cases before it stopped, officials said. more
