How do forensic scientists determine the time of death? There are timely pieces of evidence that help scientists with this task.
At the time of death:
~The heart stops
~The skin gets tight and grey in color
~Cell start to die (brain 3-7 min; skin up 24 hours)
~The muscles relax
~The bladder and bowels empty
And then what? Order these changes from FIRST to LAST.
