Locard's Exchange Principle
So what do you believe was left at the scene ?
And what do you believe was taken from the scene of the crime ?
And where was it taken to ?

Locard's Exchange Principle
Although Locard's exchange principle is generally understood as the phrase "with contact between two items, there will be an exchange," Edmond Locard never actually wrote down those words in the vast amount of material he produced, nor did he mention anything concerning a principle. Locard, however, did write the following:
"It is impossible for a criminal to act, especially considering the intensity of a crime, without leaving traces of this presence."
In other words, Locard believed that no matter where a criminal goes or what a criminal does, he will leave something at the scene of the crime. At the same time, he will also take something back with him. A criminal can leave all sorts of evidence, including fingerprints, footprints, hair, skin, blood, bodily fluids, pieces of clothing and more. By coming into contact with things at a crime scene, a criminal also takes part of that scene with him, whether it's dirt, hair or any other type of trace evidence.
So what do you believe was left at the scene ?
And what do you believe was taken from the scene of the crime ?
And where was it taken to ?
