Criminal Investigative Analysis is a term which accounts for several services performed by forensic behavioral specialists. These services include:
- Indirect Personality Assessment
- Equivocal Death Analysis
- Trial Strategy
- Criminal Profiling
"While virtually any crime showing mental, emotional, or personality aberration can be analyzed for profiling purposes, certain crimes are particularly appropriate for the process; these crimes include a series of rapes, lust murder (mutilation or displacement of the sexual areas of the body), serial murders, child molesting, ritualistic crimes, threat communications, violence in the workplace, and serial arson."

A competent profile is always grounded firmly in physical evidence. Physical evidence, competently interpreted and reconstructed, gives us victim and offender behavior. That behavior is then evidence that can be analyzed. This process should be referred to as behavioral evidence analysis.
Inputs are those materials that are necessary for the most competent profiles. Without them, the profile is merely a speculative, uninformed effort. In fact, any analysis done without most of the inputs listed below cannot be accurately referred to as a criminal profile.
"The criminal personality profile is based upon a good crime scene examination and adequate information supplied to the profiler. In order to facilitate this process there are certain steps that must be taken at the scene by the detective...
The following items are necessary to create a profile:
I. Complete crime scene photographs...
II. Neighborhood racial, ethnic and social data...
III. Complete Medical Examiner's autopsy protocol...
IV. Map of the victim's travels prior to death/attack/kidnapping...
V. Complete investigation report of the incident...
VI. Complete background of the victim (Victimology)..."

By Vernon Geberth, CRC Press, 1993
The main objective of a criminal profile is to provide investigators with specific information about unknown suspects that will aid in that suspects identification and/or apprehension. The profiling process assists the investigator by reducing the universal set of suspects (everyone) to a set of suspects with more unique habits and characteristics.
The more violent, aberrant, or sexual the crime, the more helpful profiling can be. Profiling is most helpful in, but not limited to, violent serial sex crimes. This is because as the number of offenses by an unknown suspect increases, so does the total amount of physical crime scene evidence. Each crime scene is a classroom where the unknown suspect teaches investigators more about himself.
However, each crime scene is also a classroom for the offender where he learns what behaviors to include or omit from subsequent offenses. The more advanced the offender, the less physical evidence he will likely leave the investigator to learn from.
I specialize in the forensic analysis and criminal profiling of cases involving:
- serial rape
- serial homicide
- autoerotic death
