||On January 21, 2011 an armed man robbed a Family Dollar in the Chesapeake, Virginia area.
||While fleeing the scene, the robber left behind a gray jacket, which was taken as evidence.
||The Virginia Department of Forensic Science developed DNA mixture data from the jacket.
||Due to the complexity of the three-person mixture, the lab's manual analysis could not produce a match statistic.
||On the same DNA data, the computer found that Keith Sampson matched the jacket with a match statistic of 414 billion.
||On February 28, 2012, Dr. Mark Perlin testified at the City of Chesapeake trial about the computer’s DNA match statistic.
||On March 1, 2012, the jury found Mr. Sampson guilty of all charges. He was sentenced to 26 years in prison.
