The article by Paige St John which begins on the front page of the Los Angeles Times, paper edition, dated December 10th, is detailed and excellent but at this moment I haven't found a link for it. In my labels below I've listed the companies that figure in the process in which the killer's DNA matched others. The Golden State Killer mystery was one that many a professional and citizen sleuth tried to solve. No doubt he needed to be caught. But we all wonder if our DNA that we so willfully submit for the purposes of meeting long lost relatives and solving genealogy research problems, is really as private and secure as we desire.
I may have mentioned that I've never taken a DNA test myself. My own research is off and on. There are things that took many years for me to find, again not looking every day for twenty years but still.
I remember the day I sat next to a new researcher at a Family History Center who got one spool of film and went back six generations in her German heritage family in that afternoon. Because I was working on ancestors in a Central - Eastern European country and the records were sloppy and didn't have details of the German records it has taken me many years to get back close to 1800. I'm forever interested but not obsessed.
And so you must ask yourself what you are giving up about yourself in hopes of gaining in research.
I will search for this article again in the near future, hoping it's considered important enough to have a link. If not, search out the paper edition.
THANK YOU FOR YOUR PATIENCE.
