Common questions

Why does a death investigation system need MLDIs if a medical examiner already reviews the case?+

MLDIs handle the scene-side work, including scene documentation, witness interviews, and evidence collection, freeing the medical examiner or pathologist to focus on the autopsy itself, and their scene notes directly inform the pathologist's later findings.

What training does an MLDI typically hold compared to a medical examiner?+

MLDIs are not physicians and usually complete a certification or specialised death-investigation training programme rather than a medical degree, which is why they work under the delegated authority of a coroner or medical examiner rather than independently.
