Another piece of evidence
that was handled by a number of different members of the investigation team investigating
the murders of Nicole brown and Ronald Goldman, was a pair of blood covered
leather gloves, one of which was found at the scene of the murders and another
found behind OJ Simpson’s property. The police, detectives, scenes of crime
officers and forensic scientists all handled this evidence.
Each of the members of the
investigation team who handled this piece of evidence had the responsibility to
ensure that it was part of a secure audit trail – ensuring that the evidence
remained intact and uncontaminated – by correctly bagging and labelling the
evidence and also by ensuring that the evidence was passed through a complete
chain of custody in order to make it to the forensics lab to be analysed.
Officer Robert Riske –the
first attending officer at the scene was the first team member to find the
evidence in the form of the first leather glove found at the scene of the murders.
Officer Riske approached the glove and handled it in order to investigate
whether the perpetrator may have dropped the glove or whether it belonged to
one of the victims. This can be identified as being a mistake as Officer Riske
should not have handled the evidence prior to the scenes of crime officers
arriving. Also as he was not wearing personal protective equipment he would
have contaminated the glove when handling it. Also a similar situation occurred
when detectives discovered the leather glove behind Simpsons property – the
detectives handled the glove to determine if it matched the glove from the
murder scene, however again they were not wearing personal protective equipment
in order to prevent contamination occurring to the glove.
Also primarily at the scene
of the murders of Ronald Goldman and Nicole Brown both the police and the
detectives failed to correctly secure the scene allowing a large amount of
people who were not clothed in appropriate personal protective equipment,
including members of the public into the crime scene. As all these people were
walking around various areas of the scene the evidence was not protected or
kept secure as it could easily have been contaminated or moved by different
individuals. These mistakes that were made by both the police officers and the
detectives therefore can be identified as being a failure in keeping the
evidence within a secure audit trail. These mistakes also proved to be detrimental
to the case as it again allowed the defence to argue that if the evidence was
contaminated by the team members who were supposed to keep it secure, it could
also easily have been altered and blood evidence planted on the gloves by the
team members or other individuals in order to frame Simpson, these mistakes and
the argument of contamination of evidence was a contributing factor which ended
in the acquittal of Simpson.
