Can the investigation methods in "White Night Chasing the Murder" be applied to real cases?

There are many investigation methods in Chasing the Murder in White Night, some of which can still be applied to real cases.

Chasing the Murder in the White Night is the first suspense crime drama in China directed by Wang Wei and starring Pan Yueming, Wang Longzheng, lyna, Lv Xiaolin and Yin Shuyi. The play tells the story of Guan Hongfeng, the captain of the criminal investigation detachment, who cracked many cases all the way and cleared his brother of murder.

In one episode, Guan Hongfeng said when he solved a case without leaving any criminal evidence: "As long as he enters and exits the crime scene, there will be a material exchange between the criminal and the crime scene." This is actually lorca's law, which was put forward by Edmund lorca, a master of forensic medicine. Matter is made up of countless particles. As long as the suspect goes in and out of the scene and commits a crime, it is bound to exchange particles with any object he touches. Even if a suspect with anti-investigation consciousness deliberately cleans up the traces of crime, it is difficult to clean it up completely. What forensic doctors need is to look for clues patiently and carefully, and they will certainly find them.

? American police once used this to solve a serial murder case. In fact, this Carlo law is very scientific from the physical level. Any contact between objects is bound to occur particle exchange, so any contact will leave traces. At the same time, it has a very similar meaning to the phrase "Don't reach out, you will be caught if you reach out" in China. Therefore, as a criminal police, it is still relatively difficult to solve homicide cases, especially in the face of serial homicide cases, which need to be considered from all aspects and finally solved.
