New twin-splitting technology is being put to the test for the first time ever in a Hub courtroom this week, and Suffolk prosecutors hope the new-age science can finally help solve a pair of rapes that occurred nearly 15 years ago.
An old DNA test couldn’t separate the chief suspect in the case, Dwayne McNair, from his identical twin brother, Dwight McNair. That issue put Suffolk District Attorney Daniel F. Conley in a tight spot, and in 2014 he temporarily dropped charges stemming from a pair of 2004 rapes so he could see if a new test developed in Germany would work.
Prosecutors say it did, and that it conclusively shows that Dwayne McNair’s DNA was in a condom he allegedly used during the crime. That potentially damning piece of evidence only exists because a quick-thinking woman McNair is accused of raping kept the condom and brought it to authorities.
