Abstract
In forensic science and in modern times, impalement is a rare event. When this occurrence involves the head, it is even more unusual since this region is very small compared to the rest of the body. Although impalements are rare, they represent scenarios that must be treated with great care by forensic pathologists. They may involve a mixture of blunt and penetrating wounds, and the injuries observed at autopsy must be interpreted correctly. For this reason, if possible, the interconnection between the body and the impaling object should be maintained until the autopsy table. In this report, it is presented a case of cranial penetrating trauma that occurred after a suicidal fall from a great height with impact on the railing below, by reporting both the on-site scene inspection and autopsy data. The critical forensic issues that may arise in the practical management of such cases are discussed, starting from the fact that there is still no clear and unambiguous definition of impalement.

Abstract
A 26-year-old young man died shortly after he had suffered craniocerebral impalement from a metal chair leg during an affray at an airport bar. At autopsy a 25 mm diameter circular wound was present in the left parietal region with protruding brain tissue. Death was due to craniocerebral trauma from a penetrating injury to the head. Examination of the chair used in the assault showed a metal chair with smeared blood on the front right leg that matched the blood group of the decedent. The fatal wound had been inflicted by the assailant with the victim leaning forward while kneeling on the floor. The assault had produced an unusual circular patterned defect in the left parietal bone with dimensions corresponding to the chair leg. The location of the defect and the use of a chair leg were two very unusual features in this homicide.

Abstract
Impalement injuries transfix a victim in an inescapable or helpless position. A study was undertaken at Forensic Science SA from 2002 to 2016 of all impalement deaths. There were six vehicle accidents (M:F=5:1; age 14-67 years, average age 38.5 years) involving impalements with a tree branch ( n=2; groin and chest), a metal pipe ( n=2; leg and head), a metal bridge railing (groin) and a metal fence post (chest). Two cases (both males, aged 47 and 18 years) had slipped on fences/gates, with impalements of the ankle and groin. A case of suicide (male, aged 80 years) was impaled through the head on a bolt fixed to the floor. A homicide case (male, aged 27 years) involved impalement through the chest by a spear from a spear gun. In certain cases (e.g. with anogenital injuries), differentiating accidental from inflicted impalement injuries may be difficult. In equivocal cases, adequate scene evaluations with photographic documentation are required prior to autopsy, ideally with the object available for examination.

Abstract
Two cases of accidental deaths caused by the sharp ends of fence or gate posts are reported. Case 1: A 47-year-old man was found hanging by his ankle in an inverted position on fencing. He had attempted a shortcut to a railway platform by climbing over a metal rail fence. He had slipped and been impaled through his ankle by the sharp end of the fence post, resulting in death from positional asphyxia. Case 2: An 18-year-old male slipped while climbing over a gate and died after being impaled on a spear tip finial, which had lacerated his external iliac vein. Death was due to exsanguination. These cases demonstrate two rare examples of accidental deaths from impalement by the ends of sharp fence posts. Mechanisms of death in such circumstances involve suspension with positional asphyxia and vascular injury with exsanguination.

Abstract
We present a rare case of a non-fatal impalement injury of the brain. A 13-year-old boy was found in his classroom unconsciously lying on floor. His classmates reported that they had been playing, and throwing building bricks, when suddenly the boy collapsed. The emergency physician did not find significant injuries. Upon admission to a hospital, CT imaging revealed a "blood path" through the brain. After clinical forensic examination, an impalement injury was diagnosed, with the entry wound just below the left eyebrow. Eventually, the police presented a variety of pointers that were suspected to have caused the injury. Forensic trace analysis revealed human blood on one of the pointers, and subsequent STR analysis linked the blood to the injured boy. Confronted with the results of the forensic examination, the classmates admitted that they had been playing "sword fights" using the pointers, and that the boy had been hit during the game. The case illustrates the difficulties of diagnosing impalement injuries, and identifying the exact cause of the injury.

Suicide by blunt head trauma - Two cases with striking similarities. Forensic Sci Int 2015; 255:102-5.

Abstract
There have been several forensic pathological studies on the distinction between falls from height and homicidal blows in blunt head trauma, but few studies have focused on suicidal blows. Self-inflicted blunt head trauma is usually a part of a complex suicide with more than one suicidal method applied. Actually, no reports on suicide indicate blunt head trauma to be the singular cause of death in recent publications. Cases with self-inflicted blunt trauma are often challenging for those involved in the investigation because they are confronted with findings that are also found in homicides. A refined guideline to differentiate suicidal blows from homicidal blows in blunt head trauma allows for a more accurate representation of the events surrounding death. This paper presents two cases of suicide by self-inflicted blunt head trauma in which blunt head trauma from repeatedly hitting the decedent's head with a hammer was considered to be the only cause of death.
