Our Coroner gave us

Deaths occurring under suspicious circumstances, including those where alcohol, drugs or other toxic substances may have had a direst bearing on the outcome
Deaths occurring as a result of violence or trauma, whether apparently homicidal, suicidal or accidental (including those due to mechanical, thermal, chemical, electrical or radiation injury, drowning, cave-ins and substances), regardless of time elapsing between the injury and the time of death.

Our Coroner gave us an interesting example to the importance of the underlined statement…

A rather violent fight between a couple ended with a man hanging on to the hood of his girlfriend's car as she tried several times to dislodge him by hitting other vehicles. The man went into a coma for several years until he died in the hospital.

* Any death in which trauma, chemical injury, drug overdose or reaction to drugs, medication or medical treatment was a primary or secondary, direct or indirect, contributory, aggravating or precipitating cause of death.
