4. The Investigation
Phillip Vannatter, Ronald Phillips, Tom Lange, and Mark Fuhrman were the police officers to search the premises.
Children were found upstairs asleep
Secured the scene and made a walk through
Went to O.J. Simpson’s house, where the Ford Bronco was located with blood around the exterior.
O.J. Simpson was contacted, while he was away in Chicago for a meeting.
Then he was a suspect because of his reaction and the blood on his Bronco

5. The Arrest Simpson was taken in for questioning
June 17, Simpson is located at friend’s house Robert Kardashain
Chased by police in his Ford bronco driven by friend A.C. Cowlings
Simpson is taken into custody at his home on Rockingham

10. Physical evidence continued…
Trail of bloody shoe prints
. William Bodziak, testified that the murder scene shoe prints were left by size 12 Bruno Magli casual shoes.
* Shoe comparision

11. Evidence cont.. Blood on the steps
Blood was found in front of her body and behind it on the first step.
Her body was positioned in another way as if she was killed somewhere else.
They performed a splatter test
Concluded that her throat was slashed over the step and a pint of blood came out in 5 seconds.

12. Autopsy of the victims death from multiple sharp force injuries

13. Evidence
Ross Cutlery provided store receipts indicating that Simpson had purchased a 12 inch stiletto knife six weeks before the murders.
Officers found arrest records indicating that Simpson was charged with the beating of his wife Nicole. Simpson was sentenced with 3 years of community service for this crime.

14. Blood evidence Chain of custody Must be frozen within 48 hours
The precipitin test
Chain of custody
Must be frozen within 48 hours
Benzidine color test & kastle meyer test- determine blood based on haemoglobin
Microcrystalline test(Teichmann and Takayama)
Percipitin test
RFLP or PCR
RFLP

15. RFLP testing

16. PCR results
the blood left on the glove found in the back yard at O.J. Simpson's estate matched that of Goldman and Nicole Simpson.
blood and stains found near the bodies showed genetic match with the OJ SIMPSON.
small blood stains on a sock in O.J. Simpson's bedroom had the same genetic blueprints as Nicole Brown Simpson.
blood drop lifted from O.J. Simpson's foyer contained DNA with the same distinctive series of genetic markers as Simpson's blood.
O.J. Simpson's DNA banding pattern appeared to match DNA from a blood drop from the Bundy Drive walkway leading to the rear of the residence, as well as a blood drop from driveway of Nicole Simpson's home.
And PCR tests also indicated that the nail scrapings and clippings from Nicole Simpson's body appeared to be her own.
DNA tests matched blood collection from the white Bronco, sock, glove, O.J.’s driveway, and O.J.’s home with OJ Simpson.

17. Other analysis
SEM can typically determine the species, race, and somatic origin of a hair.
Use of comparative microscope to link suspect to the crime scene.
You can also use SEM for analyze fiber structure.
Fourier transform infrared spectroscopy for fiber analysis
Scanning Electron Microscope

18. The Trail

19. The Lawyer
O.J. Simpson hired high-profile defense team led by Jonnie Cochran
He led the jury to reasonable doubt on creating doubt about the DNA evidence
Cochran suggested police bias and misconduct, and suggested mishandling of evidence
“If the glove doesn’t fit you must acquit”

20. Evidence submitted to court: Crime scene blood
Blood drops were found alongside bloody shoe prints leading away crime scene
blood was found on a gate at the back of the murder scene condominium
Both sample of blood contained O.J Simpson's genetic markers.
Simpson had a cut on his left middle finger when interviewed by police the day after the killings

21. Arguments to Crime Scene Blood
Arguments by the defense
alleged samples were sloppily collected and poorly handled, rendering DNA results unreliable
raised possibility that blood was planted by someone who took it from a police crime lab vial that contained Simpson's blood and a blood preservative; most compelling evidence was bloodstains on paper wrapping that was supposed to be holding dry blood samples
wound on Simpson's left hand was only a minor one he suffered in his house - not enough to drip as much blood as prosecutors found - and that Simpson re-injured the finger when he cut it on a glass in a Chicago hotel room the morning after killings, before police interviewed him.

22. Arguments to Crime Scene Blood
Prosecution Arguments
Place Simpson at the crime scene
He dripped blood after committing the crimes
Scientific testing and controls discarded any possibility of contamination or tampering

23. Evidence Submitted to Court: Bloody Shoe Prints
Matched a size 12 Bruno Magli, a rare Italian made shoe

24. Arguments to Bloody Shoe Prints
Arguments by the Defense
No Murder shoes were ever recovered
Thousands of shoes of that kind were sold
No evidence to show that Simpson ever owned a pair
Introduced fact that imprints were found that didn’t match the Bruno Magli shoes

25. Arguments to Bloody Shoe Prints
Prosecution Arguments
Tried to imply Simpson could have owned such pair of shoes as they were sold at Bloomingdales in New York were Simpson frequently shopped
Simpson wears a 12

26. Evidence Submitted to Court: Crime Scene Hairs and Fibers
Hairs found in a dark knit cap were similar to Simpson's hairs
Fibers on a cap were similar to those in the carpeting of Simpson's Ford Bronco
Dark blue cotton fibers were found on Goldman.

27. Arguments to Hair and Fibers
Arguments by the Defense
Hairs mean that assailant was black – 10% of LA population
Hair appeared to be dandruff free – Simpson’s hair contained dandruff
Dark blue sweat suit was never found
Fiber evidence could have been cast around scene when an officer unrolled blanket from inside house to cover Nicole’s body

28. Arguments to Hair and Fibers
Prosecution Arguments
Witness stated he saw Simpson night of the murders wearing a dark blue suit
Evidence places Simpson at crime scene

29. Evidence Submitted to Court: Bloody Gloves
One dark, cashmere-lined Aris Light leather glove, size extra large, was found at the murder scene
The Other was found behind Simpson's guest house
DNA tests showed blood on glove found on Simpson's property appeared to contain genetic markers of Simpson and both victims
a long strand of blond hair similar to Ms. Simpson's also was found on that glove.

30. Arguments to Bloody Glove
Arguments by the Defense
Glove found behind guest house was planted by racist cop - Detective Mark Fuhrman
Blood on glove was planted
Hair analysis isn’t sophisticated
Glove didn’t fit

31. Arguments to Bloody Glove
Prosecution Arguments
Simpson lost left glove in struggle
Accidentally dropped other glove while trying to hide it
Glove didn’t fit b/c it shrunk due to being soaked in blood
Also was wearing rubber gloves underneath

32. Evidence Submitted to Court: Bloody Socks
One pair of Dark socks found crumpled at foot of Simpson’s Bed
DNA test showed Genetic Markers found belonging to both Simpson and Ex-Wife.

33. Arguments to Bloody Socks
Argument by the Defense
Socks were planted in Simpson’s house
Blood was later added to socks in the lab
Most compelling evidence of tampering is that blood had soaked all the way through one sock - shouldn't have happened if a foot was in it.

34. Arguments to Bloody Socks
Prosecution Arguments
Sock directly linked Simpson to one of the victim’s

35. Evidence Submitted to Court: Bloody Bronco
Small spot of blood found near outside driver's door handle
More blood found smeared inside on console, door, steering wheel and carpeting
DNA tests showed some of the blood apparently a mixture with genetic markers of Simpson and the victims.

36. Arguments to Bloody Bronco
Arguments by the Defense
Challenged DNA results – particularly the match to Goldman
Genetic material of unknown person found on steering wheel
Police planted some of the blood
Bronco entered twice by unauthorized people while it sat in impound

37. Arguments to Bloody Bronco
Prosecution Arguments
Simpson drove vehicle to and from crime scene

38. Trial cont….
Juries didn’t understand the significance of the evidence.
Even though incontrovertible DNA evidence indicated that Simpson was present at the crime scene and that blood from Nicole and Goldman were left on Simpson’s clothes, the jury dismisses this evidence. The fact that DNA analysis identifies the different blood types with such accuracy that you could exclude every other human being on the face of the earth, seems to have been ignored by the jury. Later interviews with jury members revealed that they indeed did not truly understand how accurate DNA analysis was and that the blood evidence was not that important.
