A forensic pathologist Friday offered a chilling new explanation for cuts on O.J. Simpson's left hand, testifying that the wounds were fingernail gouges that could have been inflicted by either Nicole Brown Simpson or Ronald Lyle Goldman as they clawed to break free of a chokehold during a swift and lethal struggle.
As oversized photos of Simpson's fingers flashed on a television monitor, Dr. Werner Spitz pointed out the jagged edges of three curved wounds that measured up to 2 1/4 inches long. "These are fingernail marks," he said.
Simpson has offered contradictory accounts about the cuts on his hand. In an interview with police the day after the slayings, he said he cut his finger the previous night "when I was rushing to get out of my house" for a red-eye flight to Chicago. But during his pretrial deposition, Simpson said he suffered the lacerations when he broke a drinking glass in his Chicago hotel room after learning from police that his ex-wife had been killed.
Attempting to discredit Simpson's explanation, plaintiffs' attorneys presented evidence Thursday that there was no blood on any of the shards of glass found in Simpson's hotel bathroom. The only blood in the suite, a detective testified, was a swipe on a washcloth and several drops on the sheets and pillowcases of the bed.
Spitz followed up on Friday by flatly declaring that the lacerations he observed on photos of Simpson's hand did not have the smooth edges typical of a sharp cut. "These are not caused by glass," he said, "and these are not caused by a knife."
