Questions raised about use of DNA in identifying suspects

Jason Felch and Maura Dolan of The Los Angeles Times reported on findings that raised questions about the reliability of DNA testing to identify suspects. An Arizona state lab analyst found several instances where people shared several of the 13 markers used to distinguish individuals, findings that defied the odds estimated by the FBI. "As word spread, these findings by a little-known lab worker raised questions about the accuracy of the FBI's DNA statistics and ignited a legal fight over whether the nation's genetic databases ought to be opened to wider scrutiny." The Times found that the FBI tried to suppress the results of the Arizona lab's findings, as well as avoid similar searches at other labs.
