Study Notes
Post Mortem Interval (PMI)
- PMI is the time interval between death and the discovery of the body.
- It involves determining the "triggering event," which is the exposure of the bone to the atmosphere that starts the weathering process.
- Determining PMI involves assessing the time it took for the bone to become defleshed and exposed, then adding the time it took for the bone to reach its current state of weathering.
- The weathering stage is observed at the time of the bone's recovery.
