Profiles of serial killers have limitations

Dennis Rader, the notorious BTK murderer who eluded capture for more than 30 years until his arrest in 2005, did not fit precisely into the FBI's method for profiling serial killers on the basis of crime scenes.

And Aileen Wuornos, the Florida prostitute executed in 2002 for slaying seven men over a two-year period in the early 1990s, didn't fit at all because the database of convicted serial killers used by the FBI in developing their profiling method did not include women.

The cases of Rader and Wuornos are among the topics to be explored during a panel discussion led by Dr. Charles L. Scott, a forensic psychiatrist at UC Davis Health System, at the annual meeting of the American Academy of Psychiatry and the Law Friday at the Marriott Hotel in downtown Chicago.

Scott will examine the way the bureau develops the personality profiles used by investigators in serial murder cases. He also will look at alternative profiling methods, such as one developed by a crime writer that uses motive to sketch a female offender's likely character traits.

"The FBI profiling method has many positive attributes. But it also has some inherent limitations," Scott said. Scott, associate professor of clinical psychiatry with the Department of Psychiatry and Behavioral Science, will be one of four panelists in the talk, dubbed "Serial Killers: From Cradle to Grave." It is one of many events slated at the meeting, which began Thursday and runs through Sunday. The annual conference seeks to cover the major issues facing forensic psychiatrists.

Scott has extensive experience in legal psychiatric issues. He directs the psychiatry department's forensic case seminar, which trains psychiatrists in criminal and civil psychiatric evaluations, including assessments on insanity, competency to stand trial, personal injury evaluations, medical malpractice and danger assessments. He also serves as psychiatric consultant to the Sacramento County Jail and directs his department's forensic psychiatry residency program, overseeing training and education in landmark mental health law cases.

The purpose of Friday's panel discussion is not to critique the FBI, Scott said. Instead, it is to acquaint forensic psychiatrists with how the bureau profiles serial killers, defined as someone who has killed at least three times.

"Often, forensic psychiatrists are not trained in how the FBI does its analysis," Scott said.

Such training is important, Scott said, because forensic psychiatrists can play "an important collaborative role" with law enforcement when it comes to profiling. To support his view, Scott will cite a study that found psychiatrists were more accurate than police in profiling murder suspects. To an FBI agent, the crime scene is the key.

"The FBI would say the crime scene is like a fingerprint," Scott said. Interpreted properly, "it is likely to identify the kind of offender who would do this."
