"When Simpson returned to Los Angeles, investigators noticed a cut on a finger of his left hand.
"He told several conflicting stories about how he had gotten it, which boxed him in later when blood at the crime scene indicated that the killer had been cut on his left hand and had trailed blood outside the gates.
"That hardly seemed coincidental.
"Then when several droplets of blood at the scene failed to show a match with either of the victim's blood types, Simpson's blood was drawn for testing (after the droplets had already been collected).
"Comparison between his DNA and that of the blood at the scene showed strong similarities.
"The tests indicated that the drops had three factors in common with Simpson's blood and only one person in 57billion could produce an equivalent match.
"In addition, the blood was found near footprints made by a rare and expensive type of shoe-shoes that O. J. wore and that proved to be his size.
"Next to the bodies was a bloodstained black leather glove that bore traces of fiber from Goldman's jeans.
"The glove's mate, stained with blood that matched Simpson's, was found on his property.
"There were also traces of the blood of both victims lifted from inside Simpson's car and house, along withblood that contained his DNA. In fact, his blood and Goldman's were found together on the car'sconsole."
