Item Number



Gregg McCrary, Brent E. Turvey, expert testimony, motion in limine, criminal profiling, plaintiff's filing


Document contains the affidavit in support of the Sheppard Estate’s motion to prevent expert testimony from Gregg McCrary. The affidavit submitted by Brent E. Turvey promulgates the notion that criminal profiling is not a science, but is instead "an educated surmise and/or a non-scientific opinion." This is true, Turvey argues, because science is "an orderly body of knowledge with principles that are clearly enunciated,” and criminal profiling lacks clearly enunciated principles and “profilers do not always agree on methodology, definitions, or the application of either to individual cases." The Sheppard Estate submitted the Turvey affidavit in order to show that testimony about the use of criminal profiling to identify the personality traits of a potential killer and therefore prove Dr. Sheppard’s innocence was not grounded in science and therefore should not be submitted to the jury as evidence via expert testimony.
