State of California v. Gerald Johnson
Orange County, Case No. GG00WF0080

Gerald Johnson, 19, was accused of slashing his best friend's parents to death in their Garden Grove home in the early morning hours of December 28th, 1999. Both Brent Turvey and Jerry Chisum were retained by the defense to examine the evidence and ultimately testify as experts before the jury in this case. They came to remarkably similar conclusions from different evidentiary and behavioral angles, despite the lack of any collaboration between the two prior to their testimony.

Jerry Chisum qualified as a criminalist, and as an expert in crime reconstruction and bloodstain pattern anlaysis. He was allowed to testify as to the full weight of the conclusions his report.

Brent Turvey was qualified as a forensic scientist, and as an expert in crime reconstruction and staged crime scenes. He was allowed to discuss the fact that he had conducted a study of staged crime scenes, but was not allowed to discuss the results of that study. He was, however, allowed to give his opinion that the crime scene in this case had been staged (and discuss supporting evidence), as well as his opinion regarding the motivation evident in the crime scene. Turvey was not allowed to give his opinion regarding the nature of the relationship between the victims and the offender based on the crime scene evidence. This opinion, subsequently, has been redacted from the report provided here.

The outcome of this case, provided below, is not in disagreement with the opinions rendered by both Chisum and Turvey.
