Cadaver Dog Handbook: Forensic Training and Tactics for the Recovery of Human Remains
One of the biggest challenges a forensic investigator may face is the location of the remains of a missing person. The incident may evolve from an apparent suicide, an untimely or accidental death, or a victim of a violent crime. The information available may place the scene in the water, above ground in wooded terrain, or an urban setting, or buried in a known or suspected location. During the past decade, advances in technology have provided many sophisticated tools to assist the investigator with the location and identification of human remains. Aircraft-mounted infrared detectors, ground penetrating radar, and electromagnetic sensors are just a few that can be used to identify potential gravesites or aboveground victims. Graphing sonar, side-scan sonar, and underwater video equipment have proven beneficial during water searches. Each of these tools has limitations. Some are cumbersome and suitable for use in small areas. Graphing interpretation requires a high level of expertise, which may not be available. However, when they are combined with another readily available resource, a cadaver dog, they can be used very effectively.
