In the final analysis the active killer of Ron and Nicole had to be able to wear sizes twelve Bruno Magli Lorenzos and leave the straight pattern of bloody shoeprints on Bundy. He had to walk with the stride of a man over six feet tall. He had to have the appearance of an alibi but no real alibi.
Barring an irrational reliance on beating the laws of probability at every crucial turn in the crime and in the investigation, the killer had to have many things going for him. He had to know the dog walkers' schedule, O.J. and Nicole's schedule and when and where Ron would appear on Bundy. He had to have access to both crime scenes, some connection to the gloves, the origin of the stick, the disappearance of the denim jacket and the bath water, the appearance and disappearance of anomalous blood evidence. He had to know how the investigation process worked and at least two of the investigators. He had to be in a position to influence the investigators and the investigative process decisively from the start.
These characteristics of the killer effectively eliminate all but one possible suspect and it isn't O.J. Simpson.
O.J. and Fuhrman both could have worn the size twelve shoes. Both are over six feet tall. O.J. is pigeon-toed and Fuhrman isn't but both make contact with the ground with their toes pointed straight ahead. These combined features of the killer match no other known person in the case. The odds of them belonging to an unknown person in the case are less than the odds of blindly selecting the nine of clubs from a regulation deck of playing cards twice in a row.
The rareness of the shoeprint pattern, all by itself, virtually eliminates a drug hit or an attack for any reason by anyone who didn't know O.J. well and didn't plan from the start to frame him for a bloody murder or two. The shoeprints also eliminate Al Cowlings who is four inches taller than O.J. and wears a larger shoe. Kato Kaelin is four inches shorter than O.J. with no history of extreme violence. He would have had to wear shoes that were too big, to take longer strides than normal and to calmly plant his feet in a deliberately abnormal way (see John Junot for dissenting opinion). Ron Shipp is the right size for the stride but he, too, would have required the presence of mind to plant his feet in a way that was abnormal for him.
Furthermore, Shipp had no proven connection to the gloves or the origin of the stick. He had no access to the blood evidence in police custody and his only way of influencing the investigation from the start was thorough his long association with Mark Fuhrman.
Jason Simpson and Robert Kardashian had airtight alibis.
The biggest problems with the alibis have to do with the confusion over the time of the murders and the credibility of the LAPD. The police were not always as thorough or honest in their reporting of who did and did not have an alibi.
However, the phone record of Nicole's last conversation with her mother between 10:17 and 10:28 and Steven Schwab finding the bloody Akita at 10:55 bracket the time span of the killings to less that 27 minutes after 10:28. Other eyewitness testimony (see Dog Walkers 2) combined with the autopsy report brackets the time of killings to less than fifteen minutes shortly after 10:30. A study of the dog walker's normal Sunday night routines (see Dog Walkers 1) tells you that the killings were either planned for that time or the killer was incredibly lucky to have gotten into the courtyard, committed the murders and escaped without being caught in the act.
If you study the Kato's Walk animation carefully, you'll see that it was physically impossible for O.J. to have been anywhere but inside of his house between 10:30 and 10:56. Fuhrman and Shipp, on the other hand, had no alibis. No one even bothered to ask if Fuhrman's partner Brad Roberts had one.
The pool of suspects is thus narrowed to three people; Mark Fuhrman, Brad Roberts and Ron Shipp. Only one person without an alibi had a motive and the wherewithal to kill and frame, a fascination with blood, a history of extreme violence, a proven connection to both gloves and the origin of the stick, the killer's shoeprints, the denim jacket, the socks and the Bronco. That person is Mark Fuhrman. --Jasper
