||In Fall of 2013, an armed man robbed two banks.
||While fleeing from the second robbery, the robber dropped a
hat, which was taken as evidence.
||The Allegheny County crime lab developed DNA mixture data from
the hat, finding DNA from four or more individuals.
||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.
||On November 2, 2015, Dr. Mark Perlin testified at the Allegheny County trial about the computer’s DNA match statistic.
||On February 4, 2016, Robert Schatzman was convicted of felony robbery. He was sentenced to 1 ½ years in prison.
