current DNA sampling technology in conjunction with local agency missing
person reports, law enforcement officials have the ability to identify
or link missing person cases or unidentified human remains.
Databases are linked to the Federal Bureau of Investigation's DNA index
system, CODIS, (Combined DNA Index System) which enables the search to
reach beyond states borders and compare samples of other missing persons
or unidentified remains. Through CODIS, DNA submitted by law
enforcement agencies can be cross referenced against these samples, as
well as other available indexes to solve cases involving missing loved
ones. Once a missing person report has been filed with the local
law enforcement agency, a family may be asked to submit personal
articles belonging to the missing person, or several family members may
be asked to volunteer their own DNA samples. The local law
enforcement agency will use a specimen collection kit to collect these
family reference samples and submit it to the states DNA database.
The DNA results from these submissions will be entered into a database
and routinely compared to the DNA results obtained from unidentified
To establish a DNA profile for a person, a standard sample is necessary. This is typically an oral swab or a blood sample taken directly from that person and it represents a "known" source of DNA. If a DNA standard is not available, then a secondary standard is to select an item that has had direct and prolonged contact with the person in question. It is critical that the item is known to have been used exclusively by the person in question. A family member** may be asked to volunteer his or her own DNA sample; which is entered into a Relatives of Missing Persons Index.
