| Crime |
In Fall of 2013, an armed man robbed two banks. |
| Evidence |
While fleeing from the second robbery, the robber dropped a
hat, which was taken as evidence. |
| DNA |
The Allegheny County crime lab developed DNA mixture data from
the hat, finding DNA from four or more individuals. |
| Match |
Too complex for the crime lab’s manual interpretation method, the lab could draw no conclusion from the evidence. |

On the same DNA data, the computer connected the hat to Robert Schatzman with a match statistic of 3.84 billion. |
| Cybergenetics |
On November 2, 2015, Dr. Mark Perlin testified at the Allegheny County trial about the computer’s DNA match statistic. |
| Outcome |
On February 4, 2016, Robert Schatzman was convicted of felony robbery. He was sentenced to 1 ½ years in prison. |
