State of Washington v Emanuel Fair

TrueAllele in Halloween murder of Seattle software developer

Crime On Nov 1, 2008, Seattle software developer Arpana Jinaga (24) was sexually assaulted and killed after a Halloween party in her home.
Evidence Evidence items included a red robe found in the trash, and duct tape used to secure a gag.
DNA The Washington State Patrol Crime Laboratory developed mixed DNA data from the evidence items.
Match The crime lab could not draw conclusions from the data due to its complexity.
TrueAllele On the same DNA data, the computer found match statistics connecting Emanuel Fair to the robe (56.8 million) and the duct tape (45.7 trillion).
Cybergenetics    In November of 2016, Dr. Mark Perlin testified in pretrial hearings on TrueAllele reliability and source code. King Court Superior Court Judge Mariane Spearman denied both defense motions. On March 27, 2017 Dr. Perlin testified about the TrueAllele results in Seattle, WA.

  • Documents

      The defense filed a motion to compel source code. The prosecution responded. Nine scientists wrote declarations explaining why source code isn’t relevant to establishing reliability. Scientists test software by running executable software on data; they don’t have, read, or use source code. The documents are on Cybergenetics news page.
