California voters in November 2004 passed Proposition 69, the "DNA Fingerprint, Unsolved Crime and Innocence Protection Act, pdf to expand and modify state law regarding the collection and use of criminal offender DNA samples and palm print impressions.
The initiative gives the Attorney General's Office, California Department of Justice, and many other state and local agencies the responsibility of implementing the new law.
On this website, you will find information regarding implementation and the central features of Proposition 69, including the responsibilities of law enforcement agencies, the California courts, district attorneys, correctional agencies, federal correctional institutions and mental health and sex offender treatment facilities with respect to California's DNA database and Data Bank Program.
The Office of the Attorney General is committed to the Sexual Assault Victims' DNA Bill of Rights. The Rapid DNA Service (RADS) for all sexual assault kits collected in 46 California counties is a reflection of this commitment. Furthermore, the Attorney General has made a Sexual Assault Forensic Evidence Tracking database (SAFE-T) available to all law enforcement agencies receiving RADS services. Sexual assault victims will be able to obtain accurate and up-to-date information regarding the status of their sexual assault kit based on information entered into SAFE-T.
Per Department policy, participation in RADS and SAFE-T requires a Memorandum of Understanding signed by the DOJ and the law enforcement agencies in each participating county.
This quarterly report provides information on the number of samples received by the California Department of Justice since the beginning of the program, the number of samples received from the state Department of Corrections, the number of fully analyzed samples for inclusion in the Federal Bureau of Investigation Combined DNA Indexing System (CODIS) database, the number of profiles transferred to CODIS, the number of qualifying profiles entered into the California Department of Justice Databank from both persons and case evidence, and the number of "hits" and investigations aided by DNA evidence as reported to the National DNA Index System (NDIS). The report also confirms the accreditation status of California Department of Justice laboratories, participation in CODIS and includes an accounting of funds collected, expended, and disbursed pursuant to Proposition 69 (Penal Code section 295, subdivision (h).)
These reports compile the annual reports filed by counties on the total amount of penalty assessments collected, allocated and expended by them for authorized programs to implement the DNA Fingerprint, Unsolved Crime and Innocence Protection Act. The county reports are required by Proposition 69.
These reports provide updates on the number of DNA samples added to the statewide database, samples removed from the backlog and number of database hits.
