Science is playing an increasingly crucial role in efforts to solve crime. Soil analyses provide information about the crime scene. Blood samples track the progression of events. Even insects can be used to calculate the time of death.
The discovery of DNA analysis heralded what has probably been the most important revolution in the history of criminal investigation. At the same time, it marked a key shift in law enforcement’s approach: before long, it became clear that in addition to police and public prosecutors, an additional group of professionals would be needed provide decisive information in endeavors to solve crime. Namely, forensic scientists.
Lorna Dawson specializes in soil investigation. After all, the forest floor is as unique as a fingerprint. Philippe Esperanca can make even invisible blood traces visible. At the Frankfurt Institute of Legal Medicine, entomologist Jens Amendt works with flies and their larvae. Using insects found on a corpse to establish the time of death is a well-established method. But Amendt is taking it to the next level.
Omnipresent pollen can provide information as to who has been near a corpse, where a person went before their death, or at which time of year a person died. Due to the longevity of pollen grains, traces are sometimes conserved for thousands of years. This enables Martina Weber from Vienna to help in the investigation of contemporary crimes, as well as to evaluate the historic events in Pompeii.

Wonderful forensic scientist team
Pollen ,soil and blood pattern are very intricate precise require passion and consistent hard work.
Madam pollen forensic scientist perhaps did in her very confined age period the work of centuries by collecting much more than 4500 pollen data base is very appreciableand commendable work.
Lastly great research in field of forensic putting apart basic DNA evidence , can bring to term the crime players with no clue.Pollen extraction of 50 or 100 years old sample is very fascinating.What to say about scientists , but long live all these forensic scientist that made world a better place to live…thanks for uploading
The blood spatter analysis reminds me of Dexter Morgan 😃😃.Top documentary by DW.
As usual a great documentary by DW 👍.
❤
Most informative Documentary Coverage & introduced remarkable Knowledges for Identify of criminals through accurate Scientific efforts & evidences … I am Glad that DW channel is presenting in my YouTube Page …allot thanks
Daww' at that painting in Philippe Esperanca's office (blood splatter specialist) @26:38
DW u gotta slow down on making these awesome docs i dont have time to watch them all! 🙂
The apartheid state of ISRAEL I'll not be happy about this technology.
More secular education.. less conservative wrought crime..s
Lovely use of science but I've had a sinus infection for 7+ years no one can solve. Help the living!
first saw the use of insects on the original CSI
Love DW👍👏. Amazing episode, especially interesting the determination of the Pompeii eruption, the new method of spraying fir blood without destroying DNA, also interesting to see that methods used generally in one place (like the soil sampling in the UK or the non destructive spray in France) isn't always common practice in other parts🤯. Hope all these fields can be successfully integrated so as to benefit the whole field🤞. To catch all murders and stop more innocent people from being sentenced. Well done all the brilliant scientists and well done DW for bringing us all so enlightening content continuously.
0:16 I don't believe in the perfect murdr? Latin America has entered the chat lady
Someone will always find a way to undo what has been done. 🤔
Bit worried about these experts- They could be crazy psychos or government sponsored officials and get rid of anyone they like. I’d like to think at least x10 independent groups (with no contact) are carrying out their findings and presenting to an unbiased randomly picked jury of again at least x 10 people at the same time
A lot of new inventions in the way ❤️
I guess we need advancements in forensic science to solve the causes of the wars the west started in the last 30 years.
Like the BBC but way better
Am a University student current in my third year persuing forensic science. Never in my life did I once think be a forensic scientist, it just didn't seem visible. I wanted to be a doctor or a pilot, but forensic science has sort of a mysterious nature that appealed to me later in life. To cut a long story short, forensic is the life for me, I think I was meant to be one. Though the conditions are not that good here in Kenya, I will keep giving it my best every other day. Hopefully, I will be able to live my dream one day.
Thank you.
Pollen are everywhere- so would the evidence be in the place by this method
About 1/4 homicides here in the city of Detroit are solved. It is my hope that this sort of forensic science can solve more. There are too many “perfect crimes” here. What do you do when someone becomes ash?
Even the meticulously planned crime leaves behind foot-prints. Science has come a long way helping criminal investigations put the offenders behind the bars. Thanks for wonderful doc.
i get the feeling that 20 years from now we'll be watching a documentary about the people that got wrongly sentenced because of these techniques… we've been there before
Loved it
Warching this documentary while I eat dinner…
Thanks so much DW, for this interesting and important documentary and yet, another proof everything and everyone are connected.
During this documentary, I automatically came to think about Alexander von Humboldt and his 'invention of nature' as well… Nature which we are all part of and, nature who help us with everything, – even when solving crimes..
Thanks for sharing!
For the perfect crime you need immunity from prosecution?
E.g.BIG PHARMA AND COVID?
Sound quality should improve…
Thank you for this great work,
I really appreciate the way is used this small things from our nature to stand for justice.
Only Europeans could have do so. They took criminal investigation to another level. Now forensic laboratories conduct criminal investigations. However science is not perfect.
Thank you for this amazing documentary
