In response to EPIC's FOIA request, the California Department of Justice has released records on a controversial forensic technique. The records show that in 2014, the state agency spent more than $300,000 on STRMix, a secret technique for matching DNA. Investigators in Australia subsequently found an error in the STRMix code that produced incorrect results in 60 criminal cases, including a high-profile murder case. STRMix promises prosecutors the ability to "[c]arry out familial searches against a database, searching for close relatives of contributors to mixed DNA profiles" but the algorithm remains secret. EPIC is pursuing FOIA requests on the secret DNA matching algorithms with state agencies across the U.S.
