||25-year old Susan Sidney was pregnant with her 6th child when she was found dead on January 27, 2014. She had been fatally shot.
||A witness was pulled over two days after the shooting. The murder weapon and three other pistols were in his possession.
||The Allegheny crime lab developed DNA mixture data from four different pistols.
||Due to the complexity of the DNA mixture, the lab was unable to produce a match statistic using manual methods of DNA interpretation.
||On the same data, the computer connected Walker to the murder weapon with a match statistic of 245 trillion. Proctor matched a pistol found with the murder weapon with a statistic of 243 billion. The key witness was also matched to the murder weapon.
||On September 25, 2015, Dr. Mark Perlin testified at a trial in Allegheny county.
||Due to discrepancies in the witness’s story, the jury did not trust his testimony against the defendants. Both Henry Little-Proctor and Rashawn Walker were found not guilty.
