OJ trial forensics

The OJ Simpson case is known for its improper forensic collection. There were countless issues revolving evidence collection and chain of custody throughout the entire trial. At the crime scene, officers initially found blood in and on the white Bronco, a left-hand glove outside Brown's home (DNA analysis of the blood on the glove was claimed to be a mixture of Simpson's, Brown's, and Goldman's), a hat (suspected to have dropped off of OJ’s head during the murder – this could have most likely been the reason why he left the glove behind as well), strands of hair consistent with Simpson's found on Goldman's shirt, and bloody shoe prints. These shoe prints were identified by an FBI shoe expert to have been made by a pair of extremely rare shoes in OJ’s exact shoe size – investigators found pictures of OJ wearing the shoes right after he denied owning them. Officers later found bloody socks in OJ's bedroom; the DNA analysis identified the blood as Brown's. One thing that was not too well known is that there was a bloody fingerprint located on the gateway of Nicole Brown’s house that was never collected although it was documented, but no further action was taken to secure it. Many other items of evidence were also never entered into the chain of custody, which gave the impression that sloppy forensic collection had been carried out at the scene. Also, during the trial, prosecution had expert witnesses who testified that the evidence was often mishandled.
