The dog kept barking late on this foggy Sunday evening, June 12, 1994. Pablo Fenjves, a screenwriter, thought he heard it the first time at about 10:15. Elsie Tistaert, who lived just across the street, also heard it, and when she looked out of her window, she saw the dog, a white Akita, pacing up and down outside the front of 875 South Bundy Drive. Louis Kaupf, who lived next door to 875, returned late from the airport and went out to clear his mail at 10:50. The dog was still barking and trotting up and down in an agitated manner. Just before 11:00, Steven Schwab, who was walking his own dog, came across the distressed animal. It followed him home. There, he noticed that the dog's belly fur and paws were matted in red. Even with no murder weapon and no witnesses to the murders, the prosecution felt they had a very strong case. Supported byDNA evidence, they fully expected a conviction. From the physical evidence collected, the prosecution speculated that Simpson drove to Nicole Brown's house on the evening of June 12 with the intention of killing her. They speculated that Nicole, after putting her two children to bed and while getting ready to go to bed herself, opened the front door of her house after either responding to a knock on the front door or after hearing a noise outside, where Simpson grabbed her before she could scream and attacked her with a knife. Forensic evidence from the Los Angeles County coroner suggested that Ron Goldman arrived at the front gate to the townhouse sometime during the assault where the assailant apparently attacked him and stabbed him repeatedly in the neck and chest with one hand while restraining him with an arm choke-hold. According to the prosecution's account, as Nicole Brown was found lying face down, the assailant, after finishing with Goldman, pulled her head back using her hair, put his foot on her back, and slit her throat with the knife, severing her carotid artery. They then argued that Simpson left a "trail of blood" from the condo to the alley behind it; there was also testimony that three drops of Simpson's blood were found on the driveway near the gate to his house on Rockingham Drive. According to the prosecution, Simpson was last seen in public at 9:36 pm that evening when he returned to the front gate of his house with Brian 'Kato' Kaelin, a bit-part actor and family friend who lived with Nicole until he was given the use of a guest house on Simpson's estate. Simpson was not seen again until 10:54 pm, an hour and 18 minutes later, when he came out of the front door of his house to a waiting limousine hired to take him to Los Angeles International Airport (LAX) to fly to a Hertz convention in Chicago. Both the defense and prosecution agreed that the murders took place between 10:15 and 10:40 pm, with the prosecution saying that Simpson drove his white Bronco the five minutes to and from the murder scene. They presented a witness in the area of Bundy Drive who saw a car similar to Simpson's Bronco speeding away from the area at 10:35 pm .Simpson's initial claim that he was asleep at the time of the murders was replaced by a series of different stories. According to the defense lawyer Johnnie Cochran, Simpson had never left his house that night and that he was alone in his house packing to travel to Chicago. Cochran claims that Simpson went outside through the back door to hit a few golf balls into the children's sandbox in the front garden, one or more of which made the three loud thumps on the wall of Kaelin's bungalow. Cochran produced a potential alibi witness, Rosa Lopez, a neighbor's Spanish-speaking housekeeper who testified that she had seen Simpson's car parked outside his house at the time of the murders. But Lopez's testimony, which was not presented to the jury, was pulled apart under intense cross-examination by Marcia Clark, when Ms. Lopez was forced to admit that she could not be sure of the precise time she saw Simpson's white Bronco outside his house. Ms. Lopez was interviewed in English, without an interpreter present. Later, the defense tried to claim that Simpson could not be physically capable of carrying out the murders, for Ronald Goldman was a fit young man who put up a fierce struggle against his assailant. O.J. Simpson was a 46-year-old former football player with chronic arthritis, which had left him with scars on his knees from old football injuries. But Marcia Clarkproduced into evidence an exercise video that Simpson made two years earlier which showed that, despite some physical conditions, Simpson was anything but frail.
