The latest forensic science has not been working in John Wakefield's favor. <\/p>\n
The inventor of a new computer-assisted DNA technology testified on Tuesday that DNA matching that of Wakefield, the defendant in a murder case, was found on the amplifier cord used to fatally choke 41-year-old Brett Wentworth as well as on the victim's forearm and shirt collar. <\/p>\n
Mark Perlin, the creator of Cybergenetics True Allele Casework and the prosecution's star witness against Wakefield, 48, talked jurors through a PowerPoint slide presentation detailing the astronomical odds against the DNA he analyzed belonging to anyone other than Wakefield. <\/p>\n
Schenectady County prosecutors say Wakefield killed Wentworth in the victim's home on Wendell Avenue in April 2010, using the amplifier cord. <\/p>\n
Perlin compared the DNA found on the amplifier cord to Wakefield using his technology, which he developed over 10 years and with 25 different versions. <\/p>\n
It uses mathematical formulas to pinpoint individual human DNA on an item that may have been touched by many people. <\/p>\n
Perlin's estimates, which covered Caucasians, blacks and Hispanics, said the odds of the DNA belonging to someone else were all but impossible. <\/p>\n
Perlin said a match between Wakefield and the DNA was 300 million times more probable than a coincidental match to an unrelated Caucasian; 2.25 billion times more probable than a coincidental match to an unrelated Hispanic person; and 5.88 billion more probable than a coincidental match to an unrelated black person. <\/p>\n
During cross-examination, defense attorney Frederick Rench said that lengthy parts of the cord did not contain his client's DNA. <\/p>\n
