The Texas Department of Public Safety Crime Laboratory system was informed by the Federal
Bureau of Investigation in May 2015 of errors in the FBl-developed population database. This
database has been used by the Texas DPS Crime Laboratory system as well as many other crime
laboratories across the country for calculating match statistics in criminal investigations and other
types of human identification applications since 1999.
Upon notification, the forensic DNA community immediately began corrective action. During
implementation of corrective measures, minor discrepancies were discovered in additional data used
exclusively by the Texas Department of Public Safety. All of the errors have been corrected and the
changes have empirically demonstrated minimal impact on the calculations used to determine the
significance of an association. Further, the database corrections have no impact on the
inclusion or exclusion of victims or defendants in any result.
Ifrequested in writing, the Texas DPS Crime Laboratory System will recalculate and report
statistics previously reported in individual cases.
If you have any questions, please contact your local crime laboratory.
