Las Vegas police detect unsettled cases with record-breaking small amounts of DNA

The Las Vegas police broke a record while using the ancestry database to find suspects in the unsuspecting case. According to a BBC report, the Las Vegas police announced that they used the smallest amount of genetic samples ever recorded to detect the murder of a 14-year-old girl Stephanie Isaacso in 1989. The investigator sent only 0.12 nanograms (ie 0.00000000012 grams), or about 15 cells, to the Othram genetic sequence laboratory. For comparison, a general genetic testing kit will collect at least 750 ng of genes.
