 Civil liability has a lower burden of proof than guilty beyond a reasonable doubt but it is very rare for someone to be found liable for a crime after being acquitted for committing the crime.At the civil trial, Dr. Cotton showed the DNA in Nicole Brown's reference vial was more degraded than her DNA on the sock from Simpson's bedroom, proving it could not have come from that vial, as the defense alleged.At the civil trial, John Gerdes admitted Simpsons blood was at the crime scene and both Nicole Brown and Ron Goldmans blood was in the bronco and neither could be explained by cross-contamination.
