Commonwealth of Pennsylvania v Montre Sayles
TrueAllele identifies attacker through DNA from woman’s skin
| Crime | In 2018, a woman fled an attacker. Both were naked and running down a Pittsburgh street. |
| Evidence | The victim’s body was swabbed for DNA. |
| DNA | The Allegheny County crime lab developed data from thigh and hip DNA. |
| Match | The lab’s manual analysis gave no results “due to the complexity of the data.” |
| TrueAllele | On the same data, the computer connected Montre Sayles to the victim with match statistics in the millions and billions. |
| Cybergenetics | On September 12, 2018, TrueAllele analyst Beatriz Pujols testified at the Pittsburgh trial about the computer’s results. |
| Outcome | On September 14, 2018, Mr. Sayles was found guilty of physical assault, and not guilty of rape. |
