“Genetic Informants” and the Hunt for the Golden State Killer

Last week officers with the Sacramento County Sheriff’s Department arrested Joseph James DeAngelo, the suspected Golden State Killer who allegedly committed a dozen murders, at least 50 rapes, and more than 100 burglaries in California between 1976 and 1986. Police made the arrest after uploading DeAngelo’s “discarded DNA” to one of the increasingly popular genealogy websites. Using information from the site, investigators were able to find DeAngelo’s distant relatives, thereby significantly narrowing their list of suspects. This investigatory technique is worth keeping an eye on, not least because millions of people are using DNA-based genealogical sites.

I’m one of them. I’ve signed up to 23andMe as well as MyHeritage, both of which offer DNA analysis. I did this in part because family history is a minor hobby of mine, but also because 23andMe offers interesting medical information. While both companies offer a DNA service, I’ve only used 23andMe’s because MyHeritage allows its users to upload 23andMe data. One of the features of MyHeritage is its “DNA Matching” service, which updates me when a distant relative is found thanks to automated DNA analysis.

This month alone MyHeritage has altered me to the existence of two more 3rd - 5th cousins. This DNA Matching service has identified hundreds of my distant relatives, with varying degrees of confidence. 23andMe has a similar relative-finding feature. MyHeritage and 23andMe, as well as Ancestry.com, have all denied working with law enforcement in the Golden State Killer case.

According to The New York Times, investigators sent the suspected Golden State Killer’s DNA to GEDmatch, a free genealogical service. A GEDmatch release stated that it had not been approached by law enforcement and warned customers, “If you are concerned about non-genealogical uses of your DNA, you should not upload your DNA to the database.”

How Identification Is Overused and Misunderstood

Justice Anthony Kennedy seems to be carving out his place as the Supreme Court justice who doesn’t “get” identity. Maryland v. King was the case issued today that shows that.

His opener was the 2004 decision in Hiibel v. Sixth Judicial District Court of Nevada, which ratified laws requiring people to disclose their names to police officers on request.

Collecting Your DNA—-Not Controversial

That’s why the House of Representatives has put “Katie’s Law” (H.R. 4614, the Katie Sepich Enhanced DNA Collection Act of 2010) on the “Suspension Calendar” today. That’s the procedure for considering non-controversial bills, giving them about 20 minutes of debate.

Should Judges ‘Have the Back’ of Police Officers?

Vice-president Joe Biden says we should rally behind the Supreme Court nomination of Sotomayor because she will “have the back” of the police.  Biden is a lawyer, a senator, and former chairman of the Senate’s Judiciary Committee, so he should know better than to pull a political stunt like that to curry favor with law enforcement groups.  The Constitution places limits on the power of the police to search, detain, wiretap, imprison, and interrogate.   The separation of powers principle means that judges must maintain

E-Verify: The Surveillance Solution

The federal government will keep data about every person submitted to the “E-Verify” background check system for 10 years.

At least that’s my read of the slightly unclear notice describing the “United States Citizenship Immigration Services 009 Compliance Tracking and Monitoring System” in today’s Federal Register. (A second notice exempts this data from many protections of the Privacy Act.)
