Accidental injury by a grass strimmer: an unusual fatality

The body of a 61-year-old woman was found in the morning lying near a wire fence at her farm where she was cutting grass using a motor-powered strimmer. Autopsy revealed a laceration of the heart apex, haemopericardium and left haemothorax caused by a U-shaped wire projectile which was found lodged in the left thoracic cavity. The mechanistic analysis of the injuries and manner of death, however, were conclusive after a scene visit following the autopsy. The farm was surrounded by a wire fence to prevent wild pigs from entering in. The wire projectile was cut by unshielded blade of the strimmer and struck her chest. This case represents an unusual accidental fatality and indicates the need for improved user education and safety when using such implements. This case also reemphasizes scene investigation as an important part of medicolegal autopsy for proper determination of mechanisms of injuries and precise manner of death. We hope this report will increase awareness and alert the general public to the dangers of the grass strimmer operated without proper safety precautions.
