Forensic Gait Analysis and Forensic Gait ComparisonForensic Gait Analysis

Criminal gait comparison or forensic gait analysis (as it is commonly called) involves evaluation of the distinct features gait (or the manner in which a suspect or person walks) and comparing those gait features to those of a criminal walking (often captured on surveillance video footage or CCTV).

As a forensic podiatrist, Dr. Nirenberg is a forensic gait expert residing in the United States (USA) who has expertise linking (and unlinking) criminals captured on video (often walking) to that of suspects by comparing distinct features of their gait (how they move, walk or run).

Gait analysis may provide evidence in convicting a criminal, exonerating a wrongly accused individual or assisting in eliminating a person of interest (or providing additional evidence of wrongdoing by a person of interest).

 

Understanding Forensic Gait Analysis

Forensic gait analysis or forensic gait comparison falls into the field of forensic podiatry and biomechanics. Gait refers broadly to how people or animals move and typically gait in forensic cases it refers to the distinct features of how a criminal walks or run (often during a criminal act or criminal activity).

Here is a news story about Dr. Nirenberg’s forensic gait analysis contributing to an arrest:

Generally, forensic gait analysis or comparison is performed to assist with the identification of a criminal who can be seen walking or running (on surveillance video footage or CCTV) while performing a criminal act, such as a robbery, assault, murder, rape and so on. There may also be civil cases where the way the person in question walks may be relevant to the judge or jury.

Forensic gait analysis is an often overlooked piece of video evidence in America, though it has been used in dozens of cases in the United Kingdom. In addition to helping to identify a criminal caught on video (CCTV), forensic gait analysis may show the same individual was involved in two or more criminal acts in different locations and/or at different times. Linking (or unlinking) an unknown perpetrator caught on video (CCTV) to more than one criminal act may be useful in helping to solve the crimes.

 

Analysis of Criminal Walking or Forensic Gait Analysis at Crime Scenes

Today in America the use of video cameras for surveillance (CCTV video) of businesses and personal property is widespread and as a result criminals may be seen on video footage walking or running while in the act of performing a crime or while walking to or from the scene of the crime.

To utilize forensic gait analysis or gait comparison, a suspect is necessary for comparison. Investigators should be aware that the criminal captured on surveillance video (CCTV) may have visited the crime scene earlier in the day or in the days prior to the criminal act and this earlier video footage may reveal a person of interest. Should a person of interest be identified in the earlier video footage, the gait of the person of interest and the criminal can be compared/analyzed.

Should investigators make an arrest based in part on how the criminal and suspect walk, an expert analysis of the suspect’s walk may be beneficial in helping the jury reach a conclusion that the criminal in the surveillance video and suspect walk with similar gait features (if this is the case). Defendant attorneys may wish to have the manner of walking of their client analyzed by an expert in cases where they believe their client’s gait differs from that of the criminal in question.

Brief History of the Use of Forensic Gait in United States Courts

In the United States the way or manner that a person walks has been the subject of courtroom testimony since the early 1900s. Today, experts in the USA. and elsewhere utilize a step-wise approach to analyzing how a criminal walks (forensic gait analysis) and then perform the same approach to the suspect’s manner of walking.

The initial act in the process is for forensic experts to evaluate the video footage with the criminal and suspect walking and make a determination if the surveillance video is adequate to perform forensic gait analysis.

Forensic gait analysis and comparison of the way a criminal walks (or moves or runs) on video (CCTV) may be used to help rule in or rule out suspects, and investigators in the United States (or elsewhere) should feel free to request Dr. Nirenberg’s expert advice on how to best obtain surveillance video of suspects in criminal matters (ideally, prior to making an arrest).
