The X-Files, Season 2

Scully:
[voiceover] Death is a recorded event. For reasons natural or unnatural, when a body ceases to function, the cause of the effect can be clearly reconstructed. A body has a story to tell... If the victim was strangled, an examination of the veins in the eyes will reveal this. If the victim was shot, entry wounds and gunpowder residue can be used to reconstruct the events leading to death and help to establish a possible motive. Body temperature, preferably the temperature of the spleen, is an accurate indicator of the time of death. As are rigor, livor and levels of sodium in the blood. If the body was moved, sand, small rocks, vegetable debris, even pollen can be removed and analysed to determine the location of the original crime scene and place the position of the body at the time of death. Extracutenous stains and residues can indicate the use of poison or toxins. Hair and fibres, slivers of glass, plastic, even insect casings can serve to recreate the circumstances under which death occurred... It may be an irony only understood by those of us who conduct these examinations, who use these pieces to rebuild a narrative, that death, like life itself, is a drama with a beginning, middle and end.
