Cold Case Inquiries Stall After Ancestry.com Revisits Policy For Users (nytimes.com) 48

An anonymous reader quotes a report from the New York Times: Since online genealogy services began operating, millions of people have sent them saliva samples in hopes of learning about their family roots and discovering far-flung relatives. These services also appeal to law enforcement authorities, who have used them to solve cold case murders and to investigate crimes like the 2022 killing of four University of Idaho students. Crime-scene DNA submitted to genealogy sites has helped investigators identify suspects and human remains by first identifying relatives.

The use of public records and family-tree building is crucial to this technique, and its main tool has been the genealogy site Ancestry, which has vast amounts of individual DNA profiles and public records. More than 1,400 cases have been solved with the help of so-called genetic genealogy investigations, most of them with help from Ancestry. But a recent step taken by the site is now deterring many police agencies from employing this crime-solving technique.

In August, Ancestry revised the terms and conditions on its site to make it clear that its services were off-limits "for law enforcement purposes" without a legal order or warrant, which can be hard to get, because of privacy concerns. This followed the addition last year to the terms and conditions that the services could not be used for "judicial proceedings." Investigators say the implications are dire and will result in crucial criminal cases slowing or stalling entirely, denying answers to grieving families.
"Everyone who does this work has depended on the records database that Ancestry controls," said David Gurney, who runs Ramapo College's Investigative Genetic Genealogy Center in New Jersey. "Without it, casework is going to be a lot slower, and there will be some cases that can't be resolved at all."

    There's a reason I haven't submitted my DNA to a family-tree database.

    I don't know what skeletons lurk in my relatives' closets and I don't want to know.

    The information can still be obtained with a proper legal order or warrant. Get the warrant. If that's the requirement, then meet the requirement.

      Since these requests used to be basically fishing expeditions - see what matches against a large database - the rules will have to be changed to allow such expeditions or they will die off.

        Those types of fishing expeditions run counter to the basic principle of "presumed innocent until proven guilty", at least in my mind. So I'm not crying over this news.

        • Sure. I'm just pointing out that "go get a warrant" isn't possible in this use case precisely because fishing expeditions are prohibited under the current rules.

        • Unless a suspect themselves have tested, genetic genealogy can only produce leads for further investigation. You can't be convicted, probably not even accused on your cousins DNA alone... in a state which respects basic civil rights, at least. Which it's an open question how much the US is right now.

          Then again, if they don't respect basic civil rights, it's bold to assume they care about evidence at all, genetic or otherwise.

          I assume these are the same people who complain that they're not allowed to put cameras in people's homes that feed everything that goes on there back to the local police station. You know, just in case a crime is committed somewhere.

    • Get the warrant.

      Cases often go cold because there's not enough evidence pointing to a specific person to get a warrant. Warrants do not get issued generically for "I want to search a 3rd party private DNA database."

  • With the fact that arrests have dropped from 44,000 per year to about 11,000 per year because so many federal law enforcement agents have been taken off other beats and put on immigration enforcement....

    Seriously look it up. If we had a functional media it would be much bigger news. Most of the Democrats sucks so hard in messaging...

    To voluntarily send their DNA off to a corporation for cataloguing. Sure are a fuck ton of morons out there.

      I agree, but the people sending in the DNA don't have murders in their past, and so they're not stupidly handing themselves to the authorities on a platter. It's that nice-as-pie extended family member they don't suspect of anything untoward who's getting caught for a murder that may have been committed 20 years ago.
    • I honestly don't give the slightest fuck if a family member is convicted of a crime because of my DNA sample. In fact I'd be delighted.

      DNA is pretty low error.

    • I'm exactly that kind of moron. I've been tested by 23andMe, Ancestry, and Family Tree DNA. I've even submitted my raw data to GEDMATCH and market it as OK for law enforcement to use.

      Why would I do that? Because several reasons.
      First, I love the science and the hunt for clues.
      Second, you don't have to be personally tested, to be located through DNA. Neither Golden State Killer and Bryan Kohberger had personally been tested by a DNA service. Law enforcement instead relied on tests done by relatives, even dis

  • Get a warrant or shove off. The data was never meant for law enforcement and that it has been has stifled a lot of potential scientific discovery. Cops ruin *everything*.

  • Peoples privacy is far more inportant.

  • Because it's highly unlikely that it's for the benefit of their customers. This has been going on for a while and they seemed to be fine with it. What prompted the change in policy? There's got to be a money angle here but I'm not sure what it is.

  • The Govt. has been taking DNA samples of every member of the military since around the 80's. Are those LE departments able to access those records?

  • Ancestry did this for one reason: To keep the (genetic) data flowing to them overall. They know that people were starting to view services like theirs as suspect, at best, for privacy concerns.

    Police also knew using these services as a dragnet would cause a backlash... and they knew it because they've pulled it before themselves.

  • There is a reason why we put limits on cops - it's not to protect the guilty. It's to protect the innocent. Cops hate these limitations because it makes their job harder and they frankly do not give a crap that they are the ones breaking the law and hurting innocent people.

    I personally would never give my DNA to Ancestry.com in part because they used to let cops examine it and even now because I do not trust them to maintain their current rules. I have however given my fingerprints when I worked in fina

  • There's no reason why Ancestry cannot have the user-specified option. Crime families and tinfoil hat crowd can stay opted out, the default.
  • I had a friend who was part of BioCurious. She said that once you have someone's DNA, you can make more. It seems that between AI video and DNA replication, no one is free from being framed for anything.
    • This isn't different from fingerprint evidence. If you have someone's fingerprint, you can replicate it too. That doesn't by itself invalidate fingerprint evidence, because it has to be combined with other corroborating evidence. If your fingerprints are discovered at a crime scene, but other evidence places you somewhere else, the fingerprints by themselves won't convict you.

      Further, while fingerprints *can* be reproduced, it's not easy, and it takes skill and planning. Most crimes aren't that well thought

  • Then Why Don't the Federal Justice Department make it's own Database from all the Criminals in Custody. Take DNA From Everyone Entering the System.
  • Ancestry is doing the right thing. Its customers did not learn about their genetic history intending to help with criminal investigations. Getting a warrant should have always been a requirement, if the investigators have a good enough case and an individual that they are targeting they will not have an issue obtaining a warrant. If they are not looking for something specific that they believe that ancestry likely has then they should not just get access.to the whole data pool. Screw them.

In every non-trivial program there is at least one bug.
