Accidental fire fatality with sustained combustion.

Area of Science:

• Forensic Pathology
• Toxicology

Background:

• Sustained human combustion, or the "wick effect," is a rare phenomenon involving the partial destruction of a body by fire.
• This process is characterized by the victim's clothing absorbing liquefied fatty tissue, acting as a wick to perpetuate the flame.

Observation:

• A 59-year-old male was discovered deceased with extensive thermal burns, several feet from his vehicle domicile.
• Autopsy showed significant soft tissue loss and bone fragmentation, primarily to the trunk, with relative sparing of the upper trunk, head, and extremities.

Findings:

• Toxicology reports from autopsy blood indicated the presence of methadone (0.4 mg/L) and a trace amount of cocaine.
• No ethanol was detected in the decedent's system.
• The extensive burns and tissue loss are consistent with the "wick effect" phenomenon.

Implications:

• This case highlights the rare and devastating nature of sustained human combustion.
• Understanding the "wick effect" is crucial for forensic investigations involving fire fatalities.
• The presence of methadone and cocaine in the toxicology report may be relevant to the circumstances of the fire.
