  1. 1Postmortal intervalls (PMI) based on cases with known PMI.
  2. 2PMI estimates for cases where the death was unwitnessed, based on the last time seen alive until sampling occured. The PMIs are fairly long, but for both groups they are predominantly due to long cold storage time at the morgue before autopsy and sampling.
