Reconstruction of hit-and-run vehicle type based on un-common run-over injuries

Abstract

The main objective of investigations in hit-and-run accidents is to trace the vehicle. This is a significant challenge when there is no eye witness. It is easy when vehicle is a car or heavy vehicle since it leaves expected injury patterns. Following case discussion is based on a body found roadside with un-common run-over injuries.

An unidentified body with injuries was found roadside in supine position. There were no eyewitnesses. Autopsy revealed three groups of injuries; crushed fractures in feet, crushed laceration over the pubic area with underlying major vessels damage, and superficial abrasions over knees. Distance from feet to knee injuries was 23 inches and to pelvic injuries 46 inches. Stomach had liquor smell.

Two areas of crushed injuries with almost injury free area in-between suggest run-over by two tires. The distance between two crush injuries was 4 feet and was compatible with rear wheels of a three-wheeler. Injuries over knees were not severe and were situated midway between two severe injuries and were compatible with front tire of three- wheeler. The deceased would have been in lying position probably under the influence of alcohol. However, there were no tire marks, paint or glass fragments etc for specific identification of the three wheeler.
