Explanation: This is the place where the murders occurred. The police made the mistake of not securing the scene which allowed contamination of the blood via footprints and other DNA. Many people were allowed to walk through the area without being stopped.

There was a right-handed glove found covered in blood discarded on the side of the house.

Many officers were inside the Bronco before it could be examined which caused cross contamination.

There was blood found on the door of car that connected with the blood found at the scene of the crime. There was also blood found on the driver's side carpet, seats, instrument panel, and steering wheel. Nicole and Ron's blood were also found inside the car.

The socks found in OJ Simpson's bedroom were soaked in blood around the ankle with 29 different splatter patterns.

If I was a police officer at the scene, I would have taped off the areas where any blood could possibly be or was. I would make sure that any footprints had copies made of them before letting any other law enforcement enter to tamper.

There was EDTA found in the blood on the gate and walkway way of the house after the scene was washed away. It is a chemical only used by forensic scientists and not created naturally in blood. It shows that someone planted the blood there.

The police should not have allowed the scene to be washed before they could examine the scene. The blood found on the gate was planted after the scene was discovered which led drew the conclusion that someone tampered with the scene once more.

If I was a police officer, I would have been sure there were no unnecessary or untheorized chemicals being used. As well as keeping surveillance over the homes, so that no one could trespass to plant misleading evidence.

OJ having blood of both victims as well as his own blood in his car would be evidence that he is the killer. His blood was found on all the key points of the car that would be needed to operate the vehicle.

My critique:

Had not the police stepped into the car as well as the EDTA chemical found, this would have been solid evidence.

The shoe print at the crime scene matches the shoes that OJ claimed that he did not own.

My critique:

If the area was correctly protected, the shoeprint would have been a key identifier of our killer. There should have been a mold taken of the print by using dental cement.

The police and other staff who were allowed on the scene did not protect their evidence nor photograph it all. Even three months after, there were more things that were found and because of the period of time they had been tampered with.

If I was an investigator, these three pieces of evidence would be kept sacred. Even before they could be turned in, no one should have been near the evidence. I would have used highlighting agents to see and test the blood.

OJ Simpson denied owning the pair of Bruno Muggley's, but he was found in pictures with the exact kind of shoes.

# data[].attributes.body
It was difficult for the scientist to interpret the exact person because they had so many missing pieces. The shoe prints, chemicals, the failure to compare fingerprints, and failure to follow up with Ron's shirt's grab patterns.

My critique:

Overall, the police were given all the evidence needed to handle their case and did not have the chance to test them. Contamination is not a factor that can be looked over but, in this case, the scientist was unable to match the evidence to the blood.
