CSI of OJ's DNA

July 13, 1994 - Former NFL RB, O.J. Simpson, gives hair samples to authorities as he was being investigated for murder. 

When former NFL running back O.J. Simpson provided hair samples to authorities during the investigation into the murders of Nicole Brown Simpson and Ronald Goldman, it represents a crucial moment in what would become known as the "Trial of the Century." This event wasn't just a routine collection of evidence; it was part of a larger, highly scrutinized effort by the prosecution to build a "mountain of evidence" linking Simpson to the crime.

Hair and fiber evidence played a significant corroborating role in the prosecution's case. While not as definitive as DNA, microscopic analysis of hair samples could establish consistencies between Simpson's hair and hairs found at the crime scene, such as on a blue knit cap discovered near Ronald Goldman's body, or on Goldman's shirt. Conversely, hairs consistent with the victims could also be found on items linked to Simpson, like a glove found at his estate. These findings, when presented at trial, aimed to place Simpson directly at the murder scene and establish physical contact with the victims.

However, the collection and handling of all evidence, including hair samples, became a major battleground for the defense. The defense team, led by Johnnie Cochran, famously argued that the evidence was "compromised, contaminated, and corrupted" due to alleged police misconduct and mishandling. While the prosecution's experts, like FBI agent Douglas Deedrick, testified about microscopic similarities, the defense worked to cast doubt on the reliability of such evidence, suggesting planting or cross-contamination. The significance of providing these samples, therefore, lies not just in their potential to incriminate, but also in how they became central to the defense's strategy of creating "reasonable doubt" regarding the integrity of the investigation itself, contributing to the ultimate controversial verdict in the criminal trial.
