Compliance with Standards Governing Combined DNA Index System Activities at the Missouri State Highway Patrol Crime Laboratory Division, Jefferson City, Missouri

Audit Report GR-50-07-005
July 2007
Office of the Inspector General

Executive Summary

The Office of the Inspector General, Audit Division, has completed an audit of compliance with standards governing Combined DNA Index System (CODIS) activities at the Missouri State Highway Patrol Laboratory (Laboratory).1 The Federal Bureau of Investigation (FBI) began the CODIS Program as a pilot project in 1990. The DNA Identification Act of 1994 (Act) formalized the FBI’s authority to establish a national DNA index for law enforcement purposes.2 The Act authorized the FBI to establish an index of DNA identification records of persons convicted of crimes and analyses of DNA samples recovered from crime scenes. The Act further specified that the indices include only DNA information that is based on analyses performed in accordance with quality assurance standards issued by the FBI.

The FBI implemented CODIS as a distributed database with three hierarchical levels that enable federal, state, and local crime laboratories to compare DNA profiles electronically. The National DNA Index System (NDIS) is the highest level in the CODIS hierarchy and enables the laboratories participating in the CODIS Program to compare DNA profiles on a national level. NDIS became operational in 1998 and is managed by the FBI as the nation’s DNA database containing DNA profiles uploaded by participating states. DNA profiles originate at the local level, flow upward to the state and national levels, and are compared to determine if a convicted offender can be linked to a crime, or if crimes can be linked to each other. Thus, a laboratory’s profiles have to be uploaded to NDIS before the profiles benefit the system as a whole.

The FBI provides CODIS software free of charge to any state or local law enforcement laboratory performing DNA analysis. Before a laboratory is allowed to participate at the national level, a Memorandum of Understanding (MOU) must be signed between the FBI and the applicable state laboratory. The MOU defines the responsibilities of each party, includes a sublicense for the use of the CODIS software, and delineates the standards laboratories must meet in order to utilize NDIS.3

The objective of the audit was to determine if the Laboratory was in compliance with standards governing CODIS activities. Specifically, we performed testing to determine if the: (1) Laboratory was in compliance with the NDIS participation requirements; (2) Laboratory was in compliance with the quality assurance standards issued by the FBI; and (3) Laboratory’s DNA profiles in CODIS databases were complete, accurate, and allowable for inclusion in NDIS.

Our audit revealed that while the Laboratory was generally in compliance with the NDIS participation requirements and the FBI’s quality assurance standards, the Laboratory had not provided the FBI with complete CODIS user information for Information Technology (IT) personnel and did not submit one of its external audits to the FBI within the required 30-day timeframe. The CODIS Administrator explained that she was unaware of the Laboratory’s need to provide the FBI with information about its IT personnel who have access to CODIS, but that she would have no problem complying with this request now that she was aware of the requirement. In addition, our review of a sample of 100 Laboratory–uploaded forensic profiles revealed that 3 of the profiles were not eligible for inclusion in CODIS and therefore should not have been uploaded, and that 1 profile was inaccurate. While on site, Laboratory officials provided documentation for the deletion of the previously mentioned forensic profiles, which they agreed had been uploaded in error, as well as for the correction of the inaccurate profile.

We discussed the results of our audit with Laboratory officials and have included their comments in the report, as applicable. We made three recommendations to address the Laboratory’s compliance with standards governing CODIS activities, which are discussed in detail in the Findings and Recommendations section of the report. Our audit scope and methodology are detailed in Appendix I of the report and the audit criteria are detailed in Appendix II of the report.


  1. DNA, deoxyribonucleic acid, is genetic material found in almost all living cells that contains encoded information necessary for building and maintaining life. Approximately 99.9 percent of human DNA is the same for all people. The differences found in the remaining 0.1 percent allow scientists to develop a unique set of DNA identification characteristics (a DNA profile) for an individual by analyzing a specimen that contains DNA.

  2. DNA Identification Act of 1994, 42 U.S.C. § 14132 (1994).

  3. These standards were appended to the MOU as Appendix C - NDIS Procedure Manual. This manual is comprised of several operational procedures that provide specific instructions for laboratories to follow for procedures pertinent to NDIS. For our purposes, the NDIS participation requirements consist of the MOU and the NDIS operational procedures.
