The Rise of Genetic Testing Companies and DNA Data Race (Forbes – 4/1/2019)

• As obtaining an individual’s entire genome has become fast and cost-effective, the DNA databases of genetic information are growing by the terabyte.

DNA is Solving Dozens of Cold Cases. Sometimes It’s Too Late for Justice. (The New York Times – 4/1/2019)

• The increasing use of DNA and genetic genealogy has given new momentum to solving cold cases in the United States, from the arrest of the Golden State Killer suspect, Joseph James DeAngelo, 73, in California last year to the announcement in Alabama last month that Coley McCraney, 45, had been charged with raping and murdering two teenagers.

With fans of the genre already donning their amateur detective hats (just take a look at Reddit threads devoted to Serial and Making a Murderer), the idea is to both entertain the audience and use it to solve cases.

Journalists Need to Stop Enabling Junk Forensics (The Washington Post – 4/2/2019)

• I’ve noticed in covering this issue that journalists seem to love stories about how new “science” and new expertise are being used to solve crimes. We swallow them up, often without a hint of skepticism. That tends to legitimize those fields.

• A Bedouin woman was reported missing by the manager of a women’s shelter in Israel in January 2016. The 28-year-old’s family did not ever contact police—and they did not provide DNA samples to the national database to try and make the search easier for authorities.

  But authorities had DNA of four of the woman’s relatives in the nation’s version of the CODIS forensic database—and the genetic experts were able to link their genetic markers to a set of unidentified human remains, touching off a murder investigation, as reported in the journal Forensic Science International.
