How do forensic scientists work out time of death?

When a body is discovered in an unusual place, how do we determine when that person died?

Can we narrow the window down to minutes and seconds? 

And why is time of death important in the world of forensics? 

In Part 1 of our forensic science series of the podcast The Science Briefing, Dr Sophie Calabretto talks to Cosmos Magazine journalist Jacinta Bowler.

They discuss how to determine time of death, how long it takes for a body to decompose, and what clues these gruesome details can unlock in a murder investigation.
