Biochemical and skeletal dating methods accurately determine human age post-mortem
While biochemical markers and epigenetic clocks show strong promise for estimating age and post-mortem intervals, their current application is hindered by a lack of universal standardization, high variability, and methodological limitations.
The retrieved literature shows a clear division in forensic science. Several papers (e.g., [1], [3], [5]) highlight significant technological and biochemical advancements—such as DNA methylation and vitreous humor analysis—that correlate well with age or time since death. However, broader reviews and methodological studies (e.g., [0], [2], [11]) emphasize that these methods often suffer from high inaccuracy, lack of standardization, and limited reproducibility when applied in routine casework, making the claim contested rather than definitively supported.

There is currently no precise and secure method to accurately determine late post-mortem intervals, with carbon-14 being the only well-recognized technique.
