Orchid Cellmark was chosen as an independent, nationally accredited laboratory to conduct testing of more than 100 pieces of blood stained evidence from this high profile criminal case. Orchid Cellmark successfully obtained high quality DNA profiles from all items and of those, only one showed DNA from someone other than OJ Simpson, Nicole Brown Simpson or Ronald Goldman. This evidence was very well presented in the civil trial and the outcome was a $35M wrongful death judgment against Mr. Simpson. Orchid Cellmark is proud to have been chosen as a laboratory worthy of conducting the DNA testing in what became one of the landmark DNA testing cases of all times.

In 2002, Orchid Cellmark donated materials regarding this case to the Smithsonian.

"The O.J. Simpson murder trial was a watershed event for the use of DNA evidence in the criminal justice system," said Mark Stolorow, executive director of Orchid Cellmark. "The tremendous public interest and the pivotal role of DNA evidence in the trial helped to educate a generation of Americans to the potential of modern DNA forensic analysis. We were proud to serve as a primary source of genetic analysis and expertise during the trial and are now delighted to donate these materials to the Smithsonian for use by researchers and historians."

The Smithsonian's National Anthropological Archives collects and preserves historical and contemporary anthropological materials that document the world's cultures and the history of the discipline. This is the first time in the Smithsonian's history that DNA-related material has been added to its collections.

The donated materials include correspondence between Cellmark Diagnostics and the prosecution, materials attesting to chain of custody safeguards for the DNA evidence acquired by Cellmark, raw data from the items of DNA evidence analyzed by Cellmark, photographs of PCR results, and autoradiographs, the clear films displaying the DNA bands that are used to generate the final results of the analyses.
