The discovery of lard on the rope at the crime scene leads everyone to conclude that this may be a case of imitating a street sweeper. Then, it is time to understand the way of thinking and childhood shadow under this behavior.

When Qin Ming and Liu talked about this case, he asked him what he thought. Liu analyzed that the street sweeper may have a strong sense of loneliness, which makes him feel inferior, makes people unable to guess his thoughts, and adds to his mystery and sense of accomplishment. Qin Ming repeated Liu's words to Liu, who concluded that Liu was probably a cleaner!

Because when she told him that the victim's teeth could solve the case before, he said that he had no idea whether to knock out the victim's teeth! This kind of person who analyzes problems from the perspective of a murderer is very problematic! But Qin Ming thinks Han Tianfeng is more suspected. As a handwriting appraiser, the handwriting written is the same as that left by the sweeper!

Moreover, Chen Shiyu said that Lin Tao had investigated the background information of Han Tianfeng before. He grew up in an orphanage, and later taught in Longfan Middle School and Longfan University and stayed there, but when he went to the school for investigation, he was told that there was no Han Tianfeng in the file!

Tv drama evaluation:

The drama has both ups and downs, suspense and brain-burning details, as well as a constantly reversed plot. The play accurately shows the forensic work from all directions and angles. The play pays attention to realistic style and realistic scenes. The plot of the play is based on the unit drama in the first season, and the key line of "scavenger" is added to make the whole story more hierarchical.

In addition to solving the case, the play pays more attention to the shaping of human nature and the source behind the criminal behavior, making the game between the police and criminals more real and heavy. In the play, the "street sweeper" who controls violence by violence creates characters from childhood environment, family background, growth background and psychological changes, which makes the "street sweeper" as a villain present a three-dimensional character image.
