NOTICE REGARDING DNA MATICH STATISTICS
The Kane County State's Attorney's Office is providing the following disclosure on all cases filed from January 1, 1999 to June 1, 2015.
On June 9, 2015, the Kane County State's Attorney received notice from the Illinois State Police Forensic Biology/DNA program manager, that the FBI notified them of errors identified in the FBI STR population data published in 1999 and 2001. This population data was used by the Illinois State Police laboratory to calculate DNA match statistics in criminal cases since 1999. Calculated match statistics issued in Illinois State Police DNA reports may have been affected by these errors. The Illinois State Police Forensic Services division concurs with the FBI that the identified discrepancies are unlikely to materially affect any assessment of evidential value.
On all pending pre-trial felony cases, if a DNA report was issued by the Illinois State Police prior to June 1, 2015, we will request that the match statistics be recalculated and a new report issued.
