State of Ohio V. Laurese Glover et al, Court of Appeals of Ohio, Eighth District, Cuyahoga County. Released and Journalized, May 5, 2016.
In this 1996 case, the defendants Eugene Johnson, Laurese Glover, and Derrick Wheatt were tried and convicted of murder in the shooting death of 19-year-old Clifton Hudson. During the criminal proceedings, gunshot residue (GSR) analysis was performed using an atomic absorption spectroscopy (AAS) test. Through this analysis, it was shown that the lead particles found in the black Chevy Blazer and on Wheatt’s hands were consistent with gunfire, although the other defendants tested negatively for gunshot residue. In 2009, the defendants filed a motion for a new trial based on the advances in GSR analysis using a method called scanning electron microscopy/energy dispersive X-ray spectroscopy (SEM/EDS). Their argument was that under SEM/EDS testing, the expert who testified in the case could no longer say that what they tested with AAS would be consistent with SEM/EDS testing. The trial affirmed the court’s judgement by rejecting the defendants’ motion, saying that SEM/EDS does not invalidate the results of AAS testing.
