Police Use Genealogy Site To Locate Murder Suspect They'd Been Hunting For More Than 30 Years

DNA isn't the perfect forensic tool, but it's slightly preferable to the body of junk science prosecutors use to lock people up. It's ability to pinpoint individuals is overstated, and the possibility of contamination makes it just as easy to lock up innocent people as garbage theories like bite mark matching.
In terms of process of elimination, it's still a go-to for prosecutors. The rise of affordable DNA testing has provided a wealth of evidence to law enforcement. Investigators are no longer limited to samples they've taken from arrestees. Databases full of DNA info are within reach 24 hours a day -- and all law enforcement needs is an account and a few bucks to start tracking down DNA matches from members of the public who've never been arrested.
Investigators used DNA from crime scenes that had been stored all these years and plugged the genetic profile of the suspected assailant into an online genealogy database. One such service, GEDmatch, said in a statement on Friday that law enforcement officials had used its database to crack the case. Officers found distant relatives of Mr. DeAngelo’s and, despite his years of eluding the authorities, traced their DNA to his front door.
“We found a person that was the right age and lived in this area — and that was Mr. DeAngelo,” said Steve Grippi, the assistant chief in the Sacramento district attorney’s office.
This "search" may possibly close the books on at least ten unsolved murders featuring the same suspect DNA. The process involved, however, raises questions. But customers of companies like GEDmatch and 23andMe probably won't like the answers. Any ethical questions they may have about companies sharing DNA info with law enforcement is likely covered by the terms of service. Customers looking to the Bill of Rights may be disappointed to discover the courts have little positive to say about Fourth Amendment protections for third party records.
Adding your DNA to these databases makes this info publicly-available. If everyone's DNA was siloed off from everyone else's, genealogy services would be completely useless. It's expected your DNA info will be shared with others. If "others" includes law enforcement, the terms of service have that eventuality covered. Even if other uses of your DNA weren't specified, there's nothing illegal about law enforcement agencies creating accounts to submit DNA for matches. If there's a Constitutional challenge, the third party doctrine likely eliminates anything remaining for the court to consider once it gets past the obvious hurdle: DNA-matching services match DNA. Complete strangers are able to "access" DNA info of others without creating privacy issues.
GEDmatch's response to all of this? If you don't want your DNA to end up in the hands of law enforcement, delete your account. This isn't exactly customer-friendly, but it reflects the reality of participating in a service that offers DNA matching. Even if a company refuses to hand over info voluntarily, it probably wouldn't take more than a subpoena to knock it loose. As long as law enforcement is using the system like a customer would -- that is, simply submitting DNA for a match -- the only problems it poses are at the far end of the ethical spectrum. If it's doing anything else -- like asking companies to notify them if certain DNA samples are submitted -- then there are problems. But as long as it's not inserting itself into the supply chain, there's really no privacy invasion occurring.
