Flutterby™! : DNA false positives

New Orleans filmmaker cleared in cold-case murder; false positive highlights limitations of familial DNA searching.

The elder Usry, who lives outside Jackson, Mississippi, said his DNA entered the equation through a project, sponsored years ago by the Mormon church, in which members gave DNA samples to the Sorenson Molecular Genealogy Foundation, a nonprofit whose forensic assets have been acquired by Ancestry.com, the world’s largest for-profit genealogy company.

Careful who you give those DNA samples to, the false accusations they lead to could be your kin.
