Accidental childhood strangulation by human hair

Area of Science:

• Forensic Science
• Pediatric Safety

Background:

• A child abuse case was initiated against a mother whose infant daughter was found with strangulation marks.
• The infant was co-sleeping with the mother, who has long hair.

Observation:

• The infant was initially unconscious and cyanotic, later showing a neck ligature mark and facial petechiae.
• The incident occurred during co-sleeping, with the infant's neck entangled in the mother's hair.

Findings:

• Expert investigation included anthropometric analysis, hair strength determination, ligature mark characterization, airway occlusion force analysis, petechiae formation conditions, and literature review.
• It is scientifically plausible for infant strangulation to occur during co-sleeping with a parent possessing long hair, potentially leading to severe injury or death.

Implications:

• This forensic analysis provides a scientific basis for understanding accidental infant strangulation during co-sleeping.
• The findings can inform legal proceedings in similar child abuse cases, ensuring accurate assessment of circumstances.
• Highlights the importance of considering environmental and physical factors in pediatric injury investigations.
