The post-mortem interval (PMI) is the time that has elapsed since an individual's death. [1] When the time of death is not known, the interval may be estimated, and so an approximate time of death established. Postmortem interval estimations can range from hours, to days or even years depending on the type of evidence present. [2]
As such, hair testing results are legally and scientifically recognized as admissible evidence. [33] Hair testing is commonly used in the USA as pre-employment drug test. The detection time for this test is roughly 3 months, which is the time, that takes head hair to grow ca. 1.5 inches, that are collected as a specimen.
