The investigation into Tiger Woods’s single-vehicle crash in February is finished, but the results cannot be released publicly until Woods gives permission, the Los Angeles County sheriff said in a Facebook Livestream on Wednesday.“A cause has been determined,” Sheriff Alex Villanueva said, adding: “We have all the contents of the black box. We’ve got everything completed, signed, sealed and delivered. However, we can’t release it without the permission of the people involved in the collision.”Woods, 45, sustained severe injuries to his right leg on Feb. 23, requiring at least two operations after the S.U.V. he was driving crashed onto a hillside along a tricky stretch of road in Los Angeles County. No one but Woods, the pre-eminent figure in golf over the past quarter-century, was involved, according to the authorities.The sheriff has maintained that the crash was an accident, saying that he and his deputies did not detect signs of impairment at the scene that day. However, he said about a week later that investigators had gotten a search warrant for the event data recorder, also known as a black box, in Woods’s S.U.V. to help clarify the cause of the crash.“It’s still an accident,” he said Wednesday. “You have an accident, and you have deliberate acts. It’s an accident, OK.
