Court Explores Constitutionality Of DNA Sampling On Anyone Arrested On Felony Charges

from the is-that-legal? dept

Last month, we discussed the legality of so-called familial searches on gov't DNA databases, especially with states expanding their DNA collection practices. Specifically, familial searches involve noting similarities in DNA found at a crime scene to those in the database. However, without an exact match, police then use the results to look at relatives of whoever was in the database. Where it gets tricky is that many states, such as California, now take DNA from anyone accused of a felony, and keep that DNA -- even if they're never convicted.

Two recent stories update this discussion in interesting ways. The first highlights how a recently arrested serial killer was caught using just such a familial search, after the guy's son was arrested on a totally unrelated matter. While it's unquestionably a good thing that a serial killer has been arrested, it still raises questions about the legality of the method by which he was caught. His own DNA was never put into the database (though I'm sure it's there now), but it effectively got there because of his son.

Separately, a lawsuit is making its way through the courts exploring whether or not California's policy of storing the DNA on anyone accused of a felony is legal, and judges appear to be mixed on the matter right now, with some comparing it to taking fingerprints, but others questioning why the data should be stored if the person was never convicted of a crime. As the article notes, this is an issue that will almost certainly reach the Supreme Court eventually.

    DNA In Database

    "His own DNA was never put into the database (though I'm sure it's there now), but it effectively got there because of his son."

    Having heard this case on a local news radio station, the reporter stated that there was DNA collected in the original investigation, but had an unknown donor.It was still logged into database. Once the Son's DNA was collected and logged, it would have found a match to the unknown sample. Thus leading to an arrest and possible/probable conviction.

    On the other side, DNA is providing a means to have innocent people who were arrested and convicted, exonerated and released.
