Electrocution by arcing: a nonfatal case study

Atypical Case of Fractal Wood Burning: Two Burned Bodies

ABSTRACT

Fractal wood burning is a form of pyrography that uses high-voltage electricity to burn branching, Lichtenberg-type patterns into a wooden canvas. This process often uses electrical transformers salvaged from household appliances, such as microwave ovens, to amplify available voltage to potentially lethal levels. In this case, 2 individuals were found dead inside their burned residential garage. Initially, law enforcement was suspicious of a double homicide with subsequent arson. However, postmortem examination showed the decedents had neither fatal antemortem trauma nor significant natural disease. Findings consistent with smoke inhalation were absent, suggesting that the victims were deceased before the fire. Interestingly, one decedent had jumper cables in their hand, and their recent computer activity included fractal wood burning-related content. Upon further scene investigation, 2 microwave ovens were identified in the garage, one of which had been disassembled with its transformer found adjacent to the bodies. The decedents likely died from high-voltage electrocution with ignition of the wooden canvas starting the structural fire. Since the first reported case in 2016, there have been 33 reported deaths attributed to fractal wood burning. The current study would be the first to report multiple fatalities due to a single fractal wood burning event.

Accidental adult deaths involving ladders: A forensic perspective

A retrospective study was undertaken of autopsy cases at the Forensic Science South Australia state mortuary over a 20-year period from January 1999 to December 2018 for all cases aged ≥18 years where a ladder was mentioned in the death scene description and/or police reports. Twelve cases were identified, all of whom were male, with an average age of 56 years (range 21–83 years). The most frequent cause of death was a fall from a ladder ( n = 8; 66%), followed by electrocution ( n = 4; 33%). The falls were associated with deaths from blunt injuries, impalement and laceration. The age range of those who fell was 47–83 years (average 66 years). The three of the four deaths associated with electrocutions involved contact with power lines or live electrical wires; the remaining case involved a sharp metal ladder base cutting through a live power lead. The age range of those who were electrocuted was 21–43 years (average 35 years) – significantly younger than those who had died from falls ( p < 0.05). The increase in mean age of the population with increasing popularity of home maintenance activities may result in more cases of lethal falls involving ladders presenting for forensic assessment.
