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.
