Downtown, Simpson is being questioned as a suspect. Simpson seemed to contradict himself quite often on details he shouldn't have: whether or not he was in a hurry to catch his flight or how he cut his hand. After the questioning, Simpson voluntarily agreed to submit hair samples, fingerprints, and a blood sample in order to seem compliant and innocent. Division serologist, Thano Peratis, took the blood sample. Peratis allegedly said he took 8 CC's of blood from Simpson, but later at the trial the LAPD lab said that they could only account for roughly 6.5 CC's.
The flaw in documentation of the exact amount of blood taken from Simpson caused uproar in the defense. The defense states that the LAPD detectives purposely contaminated the crime scene in a way that would frame their client. The fact that a certain amino acid, called EDTA which is used as a preservative and added to lab samples, was present in blood spots found on the back gate of the Bundy scene and on the socks found at the foot of Simpson's bed at the Rockingham scene gave the defense a window to argue police tampering.
Even the discovery of the socks themselves was argued as a part of a police conspiracy. When the LAPD investigators searched the Rockingham scene, they took along a camera to record their findings. The videotape was to cover them from impropriety and act as a damage control moderator. Investigator Willie Ford videotaped the master bedroom after the socks were collected as evidence. Little to the police's knowledge, the camera's date and time were reset due to the camera being inactive for a long period of time.
During the trial, since there was no concrete way to determine when exactly the socks had been there, or even if they were there to begin with, caused major concern for the prosecution and implanted more reasonable doubt in the juror's minds. Further discussion about the bloodstained socks came in the form of professional witness and forensics master Henry Lee. Lee states that the way in which blood spatters caused the blood to be in the socks weren't consistent on how the blood rested on the socks surface, and not in the fibers.
Lee also noted that the socks had identical blood patterns throughout the entire sock and therefore theoretically, through the suspect's ankle. Things were beginning to go wrong with the prosecution's case. The evidence against Simpson was commonly referred to as a "mountain of evidence" by the prosecution. The defense wasn't even started when it came to diminishing the mountain into an unreliable anthill. They still had the biggest trump card left to play, but it wasn't Mark Fuhrman, he was just an appetizer.
The defense began an all out assault, focusing in on the two areas they would target to prove their client's innocence. One would be based around the racist attitude of a policeman; the other around their contention that the blood and DNA samples were corrupted by the criminalist team authorized to collect them, or worse, deliberately mishandled and in some cases illegally manipulated to form a pattern of guilt leading to their client.
It was obvious that Fuhrman could not have seized a second glove at the Bundy scene (seventeen other police officers had viewed the death scene and all had only spotted the one glove near the bodies, not two) and transported it to the Rockingham scene, framing Simpson for the murders. The defense based its whole case around two related items, turning the interrogation away from Simpson and aiming it at Fuhrman's supposed racial intolerance, combining that with its assault on the blood evidence, the way it was collected and presented by the prosecution.
With the DNA evidence in the crosshairs, Denis Fung and his assistant found themselves blasted by defensive cross-examination. Over the period of defense's questioning, they brought up the fact that a crime scene photograph showed an ungloved hand holding the blood-spattered envelope. He also admitted to placing blood samples into plastic bags, which he claimed was purely a temporary measure, although doing this could foster bacteria growth, which in turn could distort test results.
Andrea Mazzola was called to give evidence on April 20th and spent four days being grilled by Peter Neufeld, who subjected her to as severe a battering as to Dennis Fung. She agreed that she had collected most of the blood samples without any supervision from Fung, although in the preliminary hearing, Fung had claimed the opposite. Neufeld also tried hard to show that Mazzola did a sloppy job, using videotape as evidence of her resting a hand on a dirty footpath, wiping tweezers with a dirty hand, and dropping several blood swabs.
She admitted that there were times when she had made mistakes in the collection of evidence, but denied vigorously that anyone, including herself would have deliberately altered evidence. She was unable to confirm that she had carried out to the evidence truck the vial of Simpson's blood returned to the scene by Detective Vannatter, thus reinforcing the defenses notion that the blood was never handed over to Fung that day, and this delay gave the police ample time to plant blood evidence.
Mazzola finished her testimony on April 27th. Both Scheck and Neufeld had done a brilliant job in creating a smokescreen to confuse the jury over the propriety of the criminalists' activity that day in June. If there was confusion over who did what in the collection of crime scene evidence, it was minor compared to what was to come next. The most ridiculous thing about the trial preceding unfolded in a way that defies logic. The prosecution actually requested that Simpson put the bloody gloves on to show that they fit.
The defense didn't need their trump card because the prosecution just played what could be considered the defense's "ace-in-the-hole. " After leather gets wet and then has a chance to dry, it will most definitely shrink. To add to a tight fit, Simpson was wearing latex gloves at the time of 'fitting'. In front of the jury and on televisions across America, Simpson at the time was saying to the courtroom (and the audiences watching at home), "It doesn't fit. " Johnny Cochran uttered his famous clichi, "If the glove doesn't fit, you must acquit," just as Simpson finished his observation.
