Staying Home

Mar24

As someone who has worked part-time from her house for some 20 years now, there is not much difference in my routines just because we are self-quarantined. Important for me is structure. Regular times I am in my home office and a time window where I will answer the phone (but I way prefer emails).

The new adventure is ordering grocery deliveries online. Planning many days in advance is best, since store deliveries are backed up. We just got our Costco order made about 5 days ago. So happy! Also you can get weekly deliveries of vegetables from various services. I just got my first vegetable order from Imperfect Foods and they all look fine to me. Slightly different sizes of onions and one broken stalk on a celery bunch but perfecty edible. [UPDATE 25-Mar-2020: my farmfreshtoyou box just came, what gorgeous produce! If you try them, please use my refer a friend code KITT4641 ]

The other thing to get used to is playing bridge online at BridgeBase.com rather than in person at the weekly game at our club.

If you are a Beta tester at Ancestry DNA there is a wonderful new feature to play with where you can link your DNA relatives to your own tree. As soon as more people have that I will blog about it.

By the way I have been posting one flower picture a day from my garden on Instagram and from there to FaceBook.

Rootstech 2020 is Happening Now

Feb26

Rootstech is a huge, amazing genealogy conference organized by FamilySearch.org that is going on now through Saturday in Salt Lake City. This is the 10th anniversary of the conference that should be on every genealogist’s bucket list. Sadly I am missing it again this year. If you go to one, be sure to leave some time to do research in the best family history library in this country, and perhaps anywhere, just one block from the conference.

For those of us who cannot go in person, the organizers generously live stream one session in each time slot at rootstech.org (scroll down for the schedule) and for those of us who can’t watch live, they then make those presentations available at rootstech.org/category/2020-rootstech-sessions

Wednesdays live stream sessions online

If you want more, you can purchase a virtual pass and see the 30 classes that are videotaped at your leisure for a very reasonable price at rootstech.org/salt-lake/virtual-pass

Rootstech wrote a blog post celebrating the history of the conference at rootstech.org/blog/rootstech-then-and-now, but they failed to mention my wonderful brother Shipley Munson who shepherded it from a large conference to the gigantic must-go-to conference it is today. So I will celebrate him here. Thanks for everything Ship!

Shameful DNA reporting by PBS

Nov7

These days too many media outlets seem to go for sensationalism rather than facts, but not usually PBS. I watch their news hour every night and expect it to have thoughtful, in depth reporting, unlike the sound bites from many other news shows.

Thursday night’s piece on the privacy issues from DNA testing was a travesty. This misleading headline on their web site about that segment is not what I have come to expect from PBS – “Genetic genealogy can help solve cold cases. It can also accuse the wrong person.”

No, genetic genealogy does not put the wrong people behind bars. Autosomal DNA is just a very accurate tip that points police to a person or family. In order to make an arrest they next collect the suspect’s DNA from discarded items to see if it is a match to the crime scene DNA. It is those results they take to court, not the genetic genealogy theory.

The wrong person accused scenario that they refer to happened several years ago from using Y DNA, not the full autosomal DNA currently used by genetic genealogists. PBS interviewed Michael Usry about his experience of being suspected of a horrific murder because his Y matched the crime scene and even he suggested that it was not such a bad thing to catch murderers and rapists by using the DNA of their cousins. Click here for an article from 2015 about the Michael Usry case that explains what happened back then.

Note that the Y is only one of 46 chromosomes (in 23 pairs but Y pairs with X) and it is the only one which changes extremely slowly. Therefore can reach back many hundreds of years. For example I have a cousin who has a perfect Y match with a 5th cousin where their common ancestor lived in the 1600s. So clearly, the Y is just not useful for law enforcement searches.

CeCe Moore explaining how autosomal DNA led to a killer – screenshot from PBS News Hour Wednesday Nov 6

Wednesday night’s episode (click here) did a wonderful job of explaining how autosomal DNA is used to solve cold cases. PBS interviewed both famous genetic genealogist Cece Moore and Curtis Rogers, the founder of GEDmatch. I even made my husband watch it so he could better understand what I do when I help people with their DNA results. He enjoyed it.

So I was expecting Thursday’s follow up episode on genetic privacy to explain to me why so many people are worried about this issue. Personally if any of my cousins are violent criminals I am happy to out them, but I get that people did not expect this use when they uploaded to genealogy sites, so their permission is needed.

Instead Thursday’s show was highly inaccurate. So I wrote this blog post… will I cancel my PBS membership? We will see.

 

UPDATE 8-Nov-2019: A number of readers have pointed out the glaring innacuracy of the November 7 episode claiming “that Brian Dripps had been convicted of killing Angie Dodge and is serving a life sentence” when in fact the case has not even gone to trial yet. Although he confessed, he is now pleading not guilty. A recent non-sensationalist summary of that case is here: https://www.ishinews.com/events/unraveling-the-twisted-case-of-angie-dodge/

UPDATE 9-Nov-2019: The PBS NewsHour has corrected the Brian Dripps statement in November 7 episode on their website and also retracted the incorrect information towards the end of their November 8 episode.

How to find a killer using DNA and genealogy

Apr29

It was only a matter of time before the methodologies and technologies that have been developed to break genealogical brick walls and find unknown birth parents were used to identify victims and criminals. The use of DNA and genealogy to solve the horrific Golden State killer case has been sensationalized in the media for several days now. I even got a few calls from reporters as a DNA and GEDmatch expert. Also, just two weeks ago an unknown murder victim from 30 years ago, found in Florida, was finally identified from a DNA cousin match on a genealogy site.

Some of my friends and cousins are worried about the possible invasion of their DNA test privacy. Most just want to understand how this can be done, so I will try to explain that in this post. At the end of this post I will include links to other genetic genealogy blog posts that have wrestled with the issues raised.

You share about 98.5% of your DNA with this fellow

Although I have sympathy with the concerns of people who fear false identification using DNA techniques, this is not my fear. The methodology used gets to a pool of possibles whose actual DNA is then collected and compared. I have confidence in that technology. My fear is that my cousins will stop testing their DNA to help my family projects or stop uploading their tests to my favorite tools site, GEDmatch, where the DNA test results from different companies can be compared.

Click here for an article at the LA Times which went into more of the technical details of the Golden State killer case for us genetic genealogists and here for a lengthy video interview with investigator Paul Holes on how it was done.

Let me start my article by reminding all of you that every human’s DNA is about 99% the same as every other human and about 98.5% the same as a chimpanzee. The companies who test your personal genome only test a small sample of that differing 1%. To put it in numbers, our genomes have about 3 billion base pairs and the tests cover about 700,000 of those, which comes out to about .02% of your genome. Not enough to clone you or worry about, in my opinion.

Next let me remind you that uploading your DNA results from Ancestry or 23andme or wherever you tested to GEDmatch does not expose even that little bit of your DNA to the public. What happens is that your “DNA cousins” will match long sections of your data, called segments, and they can see which locations on which chromosome(s) are the same between the two of you. Therefore they know what your actual DNA code is only on those pieces they share with you. When they match you in the GEDmatch database, they can see your email address, name or pseudonym, and your kit number. With that kit number they can see what color your eyes are, what ethnicities various calculators give, and who else you match. If you have connected a family tree to your DNA they can also see the non-living people in your tree. But they have to match your DNA significantly to see any of that!

So how do you get from there to a killer?
