The sudden question made the sleepy Fang Lubai lift his spirits. He looked up, intending to see which unlucky guy was actually named by Nie Wenguang to answer the question.

The students sitting in the front row also had some easy time, Professor Nie usually didn't like to ask questions, but most of the questions were raised by students. Even if a class is all about answering questions, time is tight.

He looked around, but he didn't see any of his classmates standing up to answer the question, which made him a little puzzled.

"What else to see? Let's just talk about you! Nie Wenguang pointed to Lu Bai below, and Fang Lu Bai stood up incredulously: "Professor Nie, are you calling me?" ”

"Do you need me to repeat it again?"

Fang Lubai stood up slowly.

For Fang Lubai's reflection, the surrounding students seemed a little impatient, because this unfamiliar guy had wasted too much time.

"This classmate, could you please tell me how the four robbers should be convicted?" Professor Nie repeated it again, and then he took off the pair of reading glasses, wiped them carefully, and looked at Fang Lubai with a sly expression.

Fang Lubai didn't think about it: "A few of them should be locked up first!" ”

"Hahaha!" Many students burst into laughter.

"Can you tell us why?" Nie Wenguang looked at Fang Lubai with a smile.

"In this case, the four suspects are all workers at a construction site, and in this robbery, the victim lost his life." After finishing speaking, Fang Lubai glanced around.

The surrounding students all looked at Fang Lubai with a mocking look.

Fang Lubai sorted out his thoughts: "Although one of them frankly admitted that he killed the victim by mistake, the ownership of the murder weapon is still a mystery. In this case, the exact amount of property damage was not specified, so the severity of the sentence is still up for debate. ”

"One last point." Fang Lubai laughed: "There is an obvious scratch on the wrist of the victim's right hand, Professor Nie, please make the picture larger." ”

After finishing speaking, Nie Wenguang clicked the mouse, and the picture on the projection screen was a little blurry, but this did not affect everyone's observation.

"Please look closely, there are obvious metal scratches on the victim's wrist, please look closely at the victim's right middle finger and index finger."

After some careful debate, it was discovered that there was something unusual on the victim's two fingers.

"The murder weapon is a portable shovel with a length of 83 centimeters and a width of 35 centimeters, the wound angle is sharp, the source of the wound is neat, the wound wall is smooth, the wound cavity is shallow, and there are a small number of abrasion marks on the edge.

The surrounding students looked at Fang Lubai with some disbelief, and Nie Wenguang also asked with some curiosity: "Tell me, what else do you have doubts?" ”

"The scratches on the deceased's wrists were relatively smooth, and the nails on the deceased's two fingers were slightly bent, so I judged that these four people were not all suspects!"

"Cut! Which college student is this, who dares to brag in our trace detection class! Class leader, next time we should put a 'idlers are not allowed to enter' at the door of the lecture hall, right? ”

"Classmate, we don't object if you want to audit, but it's your fault if you disturb the progress of our class......"

Listening to the ridicule around him, Fang Lubai didn't take it to heart, but looked at Nie Wenguang on the stage with a smile.

"You go on." Nie Wenguang looked at Fang Lubai with curiosity on his face.

"That's... Professor Nie, could you please turn a few pages forward? I want to smooth out my train of thought......" Fang Lubai looked at Nie Wenguang with some embarrassment.

Nie Wenguang's fingers trembled, and the pictures on the screen also changed, until when he arrived at the first picture, Nie Wenguang raised his head and asked Fang Lubai: "This classmate, I don't know what clues you have found?" ”

The other students looked at Fang Lubai with an expression of watching the play, and seemed to think that Fang Lubai's move was completely to delay time. But there are still more than 20 minutes before the end of class, how can this little cleverness hide from everyone's eyes.

"Please turn to the third picture." There was a smile on the corner of Fang Lubai's mouth.

"Look, the scene of the crime is the victim's home, and the construction site where the four suspects are located is only about 400 meters away from the victim's home. However, in the deceased's home, the only belongings lost were the cash obtained that day, the gold earrings and silver bracelets on the deceased's body, and the rest of the cash stored in the home was not turned over. ”

A female classmate looked at Fang Lubai, who was talking eloquently, and couldn't help but retort loudly: "Maybe the four murderers killed the victim by mistake, and they panicked for a while, so they forgot to search for their belongings?" ”

"This classmate is good." Fang Lubai glanced at everyone: "But please note that this case is characterized as a burglary, and the four murderers killed people in order to suppress the victim's resistance, so the case was characterized as a burglary, through the summary just now, I don't think this is really a burglary!" ”

The answer given by Fang Lubai greatly exceeded everyone's expectations, and there was a dead silence in the classroom, and suddenly a burst of laughter broke out.

"Silence!"

Nie Wenguang slapped the table heavily, and the classroom was quiet.

"You go on."

"The victim is 27 years old, unmarried, and sells steamed buns and soy milk at a stall every morning, and sells noodles such as wontons at night, and the main scope of activities is near the construction site where the murderer is located, so these people should know each other, including the suspect who has not yet appeared."

"Editor, you continue to make it." A student next to him muttered quietly.

"The deceased's nails are rolled-up lacerations, so it can be determined that the cause of the wound should be that the victim had a fierce fight with the murderer before she died. Professor Nie, please turn the page. ”

"Look, there is a broken porcelain basin in the corner of the wall, and it can be determined that the murderer pushed the victim down in this corner, and the victim resisted desperately, and finally his fingernails caught something, which caused the nails to roll and scratches on his hands."

Looking at the students around him with puzzled expressions, Fang Lubai said a little mysteriously: "Fellow students, guess what is it that was caught in the hands of the victim and the murderer was eager to get rid of?" ”

After listening to this, the students sitting in the lecture hall couldn't help but gather around and discuss the question that Fang Lubai had just thrown.

Some of the active classmates had evil smiles on their faces and whispered about something, and after a while, the pot exploded nearby.

"Classmates over there, what answer did you come up with?"
