Fatal pediatric hyperthermia: A forensic review.

Area of Science:

• Forensic Science
• Environmental Health
• Pediatric Medicine

Background:

• A case of pediatric hyperthermia homicide is presented.
• The decedent was found with a rectal temperature of 42.2°C after being left unattended overnight in a room with a space heater.

Purpose of the Study:

• To determine the time window of heat exposure required to induce fatal hyperthermia in a child.
• To reconstruct the environmental conditions of the incident.

Main Methods:

• Scene reconstruction using the child's residence and the same space heater.
• Gathering environmental data over a 16-hour period.
• Analysis of thermal parameters using a lumped-element thermal model and an adapted Gagge's two-node model for human thermal regulation.

Main Results:

• The study determined a time window for fatal hyperthermia exposure ranging from 45 minutes to 4 hours, depending on specific variables.
• Environmental data and thermal modeling were used to simulate the conditions leading to the child's death.

Conclusions:

• Rapid development of fatal hyperthermia is possible in children under specific environmental conditions.
• This study provides critical insights into the environmental factors and exposure durations that can lead to heat-related fatalities in pediatric cases.
