||In 2011, a man with a knife broke into an Elmira woman's apartment and sexually assaulted her. In 2013, a knife-wielding assailant robbed and sexually assaulted another Chemung County woman in her apartment.
||A pair of purple knit gloves related to the 2013 rape were recovered from a nearby park.
||The New York State Police Forensic Investgation Center (Albany, NY) developed DNA data from the two gloves. Each glove showed a mixture of DNA from three people.
||The crime lab's manual analysis was unable to produce DNA match statistics for these three person mixtures.
||The computer separated the DNA mixture data from each glove into three genetic components. TrueAllele found DNA from both the victim and her boyfriend on the gloves, as well as DNA from an unknown person. TrueAllele connected this unknown DNA to Casey Wilson, with match statistics of 817 thousand (left glove) and 31.3 million (right glove).
||Dr. Mark Perlin testified about the TrueAllele match statistics at a Chemung County grand jury hearing on December 19, 2013, and at Wilson's trial on September 11, 2014.
||Casey Wilson was found guilty of two counts each of first-degree rape, first-degree burglary, first-degree criminal sexual act, and third-degree aggravated sexual abuse, as well as one count of first-degree robbery. He was sentenced to 25 years in prison for the 2011 and 2013 crimes and 15 years for burglary.
