:09:01
	First, the common fly comes to the
rotting corpse and lays its eggs.
:09:07
	This is the beginnig of the cycle.
:09:09
	Each group of insects stays for exactly fifteen days.
:09:12
	So, you have to multiply fifteen by eight.
:09:16
	The number of groups.
This equals four months.
:09:18
	Correct. In this case the cycle seems to be complete.
:09:23
	Yet, it is already in the second generation.
:09:26
	From this we may conclude that
this head is rotting for eight months.
:09:32
	By calculating and determining the number,
the look and the kind of the insects, ...
:09:35
	...you can find out the exact date of death.
:09:38
	or of the murder.
:09:39
	So our victim was decapitated
some 8 month ago.
:09:43
	And 15 days.
:09:46
	You must not forget, that the body was on
the bottom of the lake for fifteen days.
:09:49
	Before the gases which result from
decomposition brought it to the surface.
:09:56
	Where the first flies were already waiting.
:09:58
	Exactly eight and a half months.
:10:00
	Perhaps less. It was extraordinary warm then.
:10:06
	However, I may assume that the person was
decapitated between the 7th and the 10th.
:10:13
	Is that correct?
:10:15
	Let's think about it.
:10:17
	The first girl disappeard on September 9.
:10:21
	A sixteen-year-old tourist from Denmark.
:10:24
	The body was never found.
:10:27
	Same as with the others.
:10:30
	It is not nice.
:10:32
	Like Greta.
:10:36
	Poor Greta.
:10:41
	She is also on the list.
:10:43
	She is missing but we have
no proof that she is dead.
:10:46
	After finding this what's the use
of hiding from the facts.
:10:50
	There is a killer.
:10:59
	A vicious killer.
