Efficacy of entomological method in estimation of postmortem interval: a comparative analysis

Area of Science:

• Forensic Science
• Entomology
• Thanatology

Background:

• Accurate estimation of the postmortem interval (PMI) is crucial in medico-legal investigations.
• Current medico-legal methods for PMI estimation have limitations in reliability and accuracy.
• Forensic entomology utilizes insect life cycles to estimate PMI.

Purpose of the Study:

• To evaluate the reliability of the entomological method for estimating time since death.
• To compare the entomological method's accuracy against other established medico-legal approaches.
• To determine the superiority of entomological analysis in PMI estimation.

Main Methods:

• Examination and analysis of 16 insect-infested cadavers.
• Application of entomological techniques to assess insect colonization and development.
• Comparative analysis with other prevalent medico-legal methods for time since death estimation.

Main Results:

• The entomological method demonstrated statistically significant reliability in estimating time since death.
• Insect analysis proved superior to other medico-legal approaches in this study.
• Consistent and accurate PMI estimations were achieved using entomological data.

Conclusions:

• Forensic entomology is a highly reliable and statistically superior method for estimating the postmortem interval.
• Insect evidence provides valuable data for medico-legal investigations, enhancing accuracy in time since death determination.
• The findings support the broader adoption and validation of entomological methods in forensic casework.
