Although Fei Lun felt that the second broken leg case was still suspicious, he was completely sure that the blunt knife in Chengren's hand last night was the murder weapon in the previous two broken leg cases.

The reason why Faeron is so sure is because each knife has a knife pattern, just like a human fingerprint, which is never repeated.

To put it simply, even the same batch of steel cast knives will form subtle differences in density due to different cooling times, just like the bones of the same person are also sparse and dense. In addition, using the same production line to create knives will also cause subtle differences in the texture of the knife surface due to the wear and tear of the production line for each dozen knives.

One is the density of the steel of the casting knife, the other is the slight wear and tear of the production line, plus some other manual links in the middle, such as the change of air humidity at that time, etc., so even the same batch of knives produced by the same manufacturer cannot find two identical knives in the micron range. This subtle difference, though undetectable, could not escape Pheron's eyes.

From this, Fei Lun is very sure that even if Chengren is not the real murderer of the serial broken leg case, he has a lot to do with the murderer. The reason why he hasn't given up on interrogating Cheng Ren now is that he wants to take something out of his mouth, such as who gave him the knife, or where the first two pairs of hostesses with broken legs were!

"Since you're not hungry, I'll bring you food later!" As he spoke, Faren wanted to walk out of the elevator room, but when he got to the door, he turned around and said, "Oh yes, you must remember to drink that glass of water, because I added some small amounts of medicine to treat mental retardation in it." I've read your information and found that your mental retardation is acquired, and if treated promptly, it should make your brain turn a little faster. ”

"What? What did you say? Hearing Fei Lun's words, a trace of surprise appeared on Chengren's face, but a flash of fear flashed in his eyes. This subtle change in expression did not escape Faeron's eyes.

Pheren didn't respond to him and walked straight out of the elevator room.

Back in the office, Qiu Zhaoqiang asked, "SIR, how is the trial?" ”

"It's early." "This interrogation is like a simmering meat, you have to take your time!" ”

At this time, the office phone rang, and after Mo Wanning answered, she said: "Fei SIR, the tortoiseshell called and said that the Department of Justice is very cautious about prosecuting the mentally handicapped (Chengren) homicide, although the prima facie evidence is very sufficient, they still want to study it again before deciding." ”

When Qiu Zhaoqiang heard this, he said worriedly: "SIR, this ......"

Fei Lun high-fived and said, "Ha, it's right in the middle!" Hadron do you know why I submitted the forensic report to the Department of Justice before it came out? ”

"COULD IT BE SIR THAT YOU GUESSED THEY WOULD DRAG ON TIME?"

"Bingo!" Fei Lun said with a smile, "There is only the testimony of eyewitnesses, which is actually very reluctant in legal theory, and the suspect is mentally retarded, which is even more reluctant, but the problem is that the murder case is not a small case, and they dare not let it go, after all, Chengren was caught by us at the scene of the murder, so the Department of Justice intends to delay it, and the intention is obvious, which is to give us time to find more evidence." ”

Mo Wanning said: "But what if the 48 hours are up? ”

"Stupid, don't you have a forensic report!" Qiu Zhaoqiang obviously understood, "As long as the forensic evidence proves that the blunt knife in Chengren's hand is a murder knife, how can he get away with it?" Sensei said that it has been 48 hours, and it is no problem to lock him up for another 96 hours. ”

"But what if the blunt knife isn't a murderous knife?" Mo Wanning asked rhetorically.

"YES, SIR, WHAT IF THAT BLUNT KNIFE ISN'T THE MURDER WEAPON?" Qiu Zhaoqiang also turned his head to look at Fei Lun.

Fei Lun spread his hands and said, "Then we will only talk about it then!" After speaking, Shi Shiran entered the office.

After that, every two or three hours, Feron would go to the elevator room, bring some water and food to Chengren, and say things like "You look much better" and "You're like two people when I first saw you." At night, no one said good things in Chengren's ear all night, which aggravated his "longing" for Fei Lun!

The next day, the forensic report came out, confirming that the blunt knife in Chengren's hand was indeed a murder weapon. Now, the Serious Crime Team has enough reason to detain Cheng Ren, and there is no need to rush to release him.

So, Fallon repeated yesterday's "compliment", and this continued until Friday.

The others were not idle, and according to Luo Chen's confession, they searched his two locations and moved all the things that could be packed in the evidence bag back to the serious crime team. At the same time, according to the method taught by Pheron, it is classified.

After eating at noon, Fei Lun found Qiu Zhaoqiang and said, "Qiangzi, after drinking afternoon tea, you go to deliver food and water to Chengren, I won't go!" Remember, no matter what he says, you don't say anything, just keep a straight face, understand? ”

“YES，SIR！”

Although Faeron rarely used conventional methods in interrogation, the effect was surprisingly good, which made the people of the serious crime team learn a lot, and Qiu Zhaoqiang had already been convinced.

After afternoon tea, Fei Lun returned to the serious crime team with his subordinates, and everyone consciously started working again. After a while, Qiu Zhaoqiang, who went to deliver food to Chengren, turned around and reported: "SIR, Chengren wants to see you!" ”

"Oh!?" Faeron raised an eyebrow, "It seems that the meat is stewed, and it's time to eat it." ”

At this time, Dai Yan, who led several other people to classify Luo Chen's belongings, also came over and said, "Fei SIR, everything has been divided and marked on the map, do you need to take a look?" ”

"Of course I want to, as for Chengren, I'll stew him for a while." With that, Pheren moved to the large office outside.

Luo Chen's two footholds, one in Wan Chai and the other in Prince Prince, saw that on the map, these two areas were densely marked with red dots.

"SIR, these points are consistent with the whereabouts described in the details of Luo Chen's confession, why are we marking them out?" Shi resolutely wondered.

Fei Lun waved his hand and smiled: "You don't understand what I mean, according to Luo Chen's confession, his whereabouts in the recent period are generally mastered by Ji Bingxiong and his subordinates, and he can find Bomb Chen when he is most embarrassed, what does this mean?" ”

Everyone was stunned by these questions, and Li Lidong was the first to react and said: "This shows that Ji Bingxiong and his gang are probably observing Luo Chen's situation in the dark." ”

When Fei Lun heard this, he gave him a thumbs up, and pointed to the red dots on the map and said, "So I believe that there must be a foothold of Ji Bingxiong's gang near these red dots." Although the range is still very wide, it is better than the paparazzi looking for a needle in a haystack on the street every day. ”

Hearing this, everyone suddenly had a feeling of enlightenment.

"Tortoiseshell, now your task is to link the red dots, but any public place or house that can monitor more than two red dots at the same time will be marked with a black pen for me. ”

"SIR, DON'T WORRY, WE'LL DO IT!" Dai Yan patted his chest and said.

Fei Lun waved his hand noncommittally and walked straight out of the office, where he would become a benevolent.

Opened the door lightly and entered the elevator room lightly, Fei Lun saw that Chengren, who had been waiting for a long time, looked a little manic, and actually punched the wall very slowly and rhythmically, still not a heavy punch, making some noise.

"Hey, Chengren, it seems that you are in much better shape than when you came in!" Feren sneered, "I still have the strength to get past the wall." ”

Hearing Fei Lun's voice, Cheng Ren Huo Ran turned around, then held his head and squatted down and stammered: "Fei SIR, I, I...... I didn't call you, I didn't call you, it was, it was ......" At this, his face was completely buried.

Fei Lun closed the door casually and looked at Chengren with his arms crossed. It didn't take long for Chengren to raise his head, and his eyes became extremely fierce, but Fei Lun was sure that this guy was not the "personality" who ate human flesh and drank human blood that night.

"SIR, ARE YOU LOOKING FOR ME?" The ferocious Chengren glared at Fei Lun and said, "These days, the mentally handicapped (mentally retarded Chengren) seems to worship you so much, are you trying to snatch him from me?" ”

"As I expected, your intelligence is fine." Fei Lun sneered, "I have no interest in snatching Chengren, but it depends on your cooperation, if I can't be satisfied......"

Before he finished speaking, the fierce Chengren clasped his hands tightly and waved his arms at Fei Lun.

Fei Lun didn't dodge or dodge, grabbed the handcuffs on the fierce Chengren's wrist with one hand, twisted it slightly, twisted his arms together, and pressed it down again, and the fierce Chengren involuntarily knelt on both knees.

"Chengren, attacking the police is not a small crime, especially attacking the police at the police station." Fei Lun was laughing when he said this, but his eyes were cold, and he continued to increase his strength, pressing the bones of the fierce Chengren's whole body to a click.

"SIR, I'M NOT CHENGREN, I CALL CHENGJI, I, I OBEY YOU!" The fierce Chengren (Cheng Kill) forehead was full of beads of sweat the size of beans, and he couldn't help but say soft words.

Fei Lun didn't stop the afterburner, and sneered: "Then tell me first, who is that guy who drinks blood and eats meat?" ”

Cheng Kill was slightly stunned, and then said: "What you said must be crazy!" That guy will go crazy from time to time, and he likes to eat human flesh and drink human blood, but his hobby is the same as mine, and he hates those ** who wear purple and pink nail polish and tattered clothes! ”

“**？ I don't quite understand what you mean? Who is the biggest ** in your mind? As he spoke, Pheren added two more points of force with one hand.

Cheng Kill's whole body was trembling, and he roared: "The biggest **, naturally, is Shen Jiao's rotten thing ridden by 10,000 people!" ”

"Shen Jiao? Your mother?! ”

"She's not my mother, she's just a who hooked me up in front of me and almost kicked me into an idiot. Child! Speaking of this, the strength on his body suddenly increased a little, but he still couldn't move a little under Fei Lun's strong pressure.

Fei Lun laughed and said, "Cheng Kill, I think she must have made a deep impression on you at the time, and she must have put nail polish on her feet, right?" ”

"Yes and what? The one I hate the most is the ** with purple pink nail polish! Hey, so a few years ago, I stumbled upon that again while looking for food in the garbage heap. Sub-......" (To be continued)
