Differential Identification of Three Young Housefire Victims: Methods when Age Assessment Fails.

Area of Science:

• Forensic Anthropology
• Forensic Odontology

Background:

• Mass fatality incidents involving multiple children of similar ages, including twins, present unique identification challenges.
• Standard age assessment methods may yield inconclusive results in such complex scenarios.

Observation:

• In an urban fire case with four child fatalities, dental age assessment using the Moorrees, Fanning, and Hunt (MFH) method provided insufficient results for three victims.
• Graphical plotting of the MFH data revealed distinct growth patterns between identical twins and a third child.

Findings:

• The graphical analysis allowed for the positive identification of the non-twin victim through exclusion, based on their differing growth pattern compared to the twins.
• Statistical testing confirmed the findings derived from the graphical interpretation of the age assessment data.

Implications:

• This case demonstrates a novel application of age assessment data, repurposing it for graphical differentiation and identification of child victims in mass fatality incidents.
• Radiographic and clinical presentations in childhood identical twins can reveal genetic versus acquired traits, valuable for both individual identification and exclusion.
• This method offers a valuable tool for forensic investigators dealing with the identification of multiple child victims with similar chronological ages.
