Cummings found more reason to doubt the verdict when she ordered DNA testing on fingernail clippings that had been taken from Ho during an autopsy in 1991. The prosecution had contended that Hollman was not the shooter, but argued that he had struggled with Ho while the never-identified gunman fired the fatal shots. In her court filing, Cummings reported that investigators got the DNA test results back in May. They showed Hollman’s DNA was not on the nail clippings, strongly suggesting, Cummings said, that he was not involved.
