CODIS stands for Combined DNA Index System (US FBI).

The CODIS software contains multiple different databases depending on the type of information being searched against. Examples of these databases include, missing persons, convicted offenders, and forensic samples collected from crime scenes. Each state, and the federal system, has different laws for collection, upload, and analysis of information contained within their database. However, for privacy reasons, the CODIS database does not contain any personal identifying information, such as the name associated with the DNA profile.

The uploading agency is notified of any hits to their samples and are tasked with the dissemination of personal information pursuant to their laws. The creation of a national DNA database within the U. The Act also required that laboratories participating in the CODIS program maintain accreditation from an independent nonprofit organization that is actively involved in the forensic fields and that scientists processing DNA samples for submission into CODIS maintain proficiency and are routinely tested to ensure the quality of the profiles being uploaded into the database.

For assistance in criminal investigations three indexes exist: the offender index, which contains DNA profiles of those convicted of crimes; the arrestee index, which contains profiles of those arrested of crimes pursuant to the laws of the particular state; and the forensic index, which contains profiles collected from a crime scene. These indexes include the staff index, for profiles of employees who work with the samples, and the multi-allelic offender index, for single-source samples that have three or more alleles at two or more loci.

While CODIS is generally used for linking crimes to other crimes and potentially to suspects there are non-criminal portions of the database such as the missing person indexes. Created in using the existing CODIS infrastructure, this section of the database is designed to help identify human remains by collecting and storing DNA information on the missing or the relatives of missing individuals. As of September [update] , NDIS contained more than 14 million offender profiles, more than 4 million arrestee profiles and more than one million forensic profiles.

As of September [update] , CODIS had aided in over thousand investigations and produced more than thousand hits. For this reason, a number of profiles that are present in state level databases are not in the national database and are not routinely searched across state lines.

The bulk of identifications using CODIS rely on short tandem repeats STRs that are scattered throughout the human genome and on statistics that are used to calculate the rarity of that specific profile in the population. At each location tested during DNA analysis, also known as a locus plural loci , a person has two sets of repeats, one from the father and one from the mother. Each set is measured and the number of repeat copies is recorded.

If the repeat numbers differ they are said to be heterozygous. Every possible difference at a locus is an allele. As of January 1, , requirements for upload to national level for known offender profiles is 20 loci. Since mtDNA is passed down from mother to offspring it can be used to link remains to still living relatives who have the same mtDNA.

Since then, the requirement has expanded to include seven additional loci. Partial profiles are also allowed in CODIS in separate indexes and are common in crime scene samples that are degraded or are mixtures of multiple individuals. Upload of these profiles to the national level of CODIS requires at least eight of the core loci to be present as well as a profile rarity of 1 in 10 million calculated using population statistics.

Loci that fall within a gene are named after the gene. For example, TPOX, is named after the human t hyroid p er ox idase gene. For example, D3S is on the third chromosome and is the th location described.

These sections should not be able to tell investigators any additional information about the person such as their hair or eye color, or their race. While the U. If the request is reasonable and the profile being searched would meet inclusionary standards for a U. Collection upon conviction only Collection from some felony arrests Collection from all felony arrests. Currently, all 50 states collect DNA from those convicted of felonies. A number of states also collect samples from juveniles as well as those who are arrested, but not yet convicted, of a crime.

The collection of arrestee samples raised constitutional issues, specifically the Fourth Amendment prohibiting unreasonable search and seizure. It was argued that the collection of DNA from those that were not convicted of a crime, without an explicit order to collect, was considered a warrantless search and therefore unlawful. King that the collection of DNA from those arrested for a crime, but not yet convicted, is part of the police booking procedure and is reasonable when that collection is used for identification purposes.

The inheritance pattern of some DNA means that close relatives share a higher percentage of alleles between each other than with other, random, members of society.

By focusing on close matches, investigators can potentially find a close relative whose profile is in CODIS narrowing their search to one specific family.

  1. It will never get better. GM was bailed out yet car prices are lubricous. Chrysler, Ford and GM are taking advantage of the consumers.
