After returning to the scene of Liu Jianren's death, Xu Tiannan took out the golf club from the large evidence bag and found that it was a niblick club less than 1 meter long. The entire shaft was made of carbon steel.
, very light weight.
Xu Tiannan asked: "Where was this club found?"
Xu Wudi pointed to a line marked by a trace line on the ground, and explained: "It was thrown here. I also checked the surface of this club, and there was only Liu Jianren's fingerprint."
Xu Tiannan said: "Since this cue was brought by the murderer, but now it is stained with Liu Jianren's fingerprints, it seems that during their fight, this cue was snatched away by Liu Jianren."
"What's the use of this?"
Wen Sibao stepped forward and asked: "Only Liu Jianren's fingerprints were left on this club. This clue is not enough for us to identify the murderer."
Xu Tiannan raised the club, pointed it at the light in front of him, and explained: "Look carefully at this club. Do you find anything unusual?"
Wen Sibao looked carefully and seemed to have found some clues, but he hesitated and said uncertainly: "It seems... there is some bend in the front half of this club, as if... during their fight tonight, someone was beaten
Bent?"
"Yes, that's the problem!"
Xu Tiannan took out several clubs that the police found in the trash can just now, placed them on the ground, compared them one by one, and explained.
——"Look, these clubs that are thrown into the trash can all have one characteristic, that is, they are too long to be carried around."
——"But these discarded clubs are almost all brand new and straight, only the top of the one left at the scene is bent."
——"So it is basically certain that the short club at the scene was probably bent during the fight tonight."
Later, Xu Tiannan waved the club, making a "whooshing" sound, and said to Li Mengxue: "Check the two corpses at the scene and see if there are any injuries that can match the injuries left by this club."
Li Mengxue and Xu Wudi started working immediately. About 10 minutes later, the two voices were heard.
Xu Wudi: "In addition to the electric shock injuries on this guy's body, the only injuries on his nose and mouth were from being bumped on the ground!"
Li Mengxue: "Liu Jianren's fatal injury was a laceration on his neck. In addition, there was a deep tooth mark on his right calf. Four teeth in quadrant 1 of the tooth mark were missing. After comparison, it was confirmed that this is the tooth mark today."
Teeth marks left from Wan’s fight with the Rag King.”
Xu Tiannan: "Great, it's much easier now. From the looks of it, Liu Jianren probably took this club and hit the murderer who didn't show up tonight, and it was bent."
But Wen Sibao put forward a different opinion, "Isn't it right? Tiannan, if during the fight between these people, the club did not hit the person, but hit the furniture or some hard objects
, will also cause this kind of bending mark, right?”
"It's very unlikely."
Xu Tiannan said, took out a magnifying glass, put the curved part of the club under the light, and explained while examining it carefully.
——"Look, this is a carbon rod with a hollow center. Although the front half is now bent, there are no obvious impact marks on the curved surface."
——"And the cover cloth on the sofa in this living room has no wrinkles, so it can be seen that the fight between these people was not on the sofa."
——"Therefore, the most likely thing is that Liu Jianren was holding this club and hitting the other murderer's body, causing the bending caused by the collision with the bones under the skin and flesh of the human body."
After Xu Tiannan finished speaking, he asked the delivery boy at the door: "Brother, please recall again, what kind of clothes was the person you saw who bumped into your car tonight wearing?"
The delivery boy recalled: "Well...the black shirt and pants were buttoned up at the collar and cuffs."
"Are you wearing anything else under your shirt?"
The delivery boy shook his head, "Probably not. Although I didn't see his face clearly at the time, when I helped him up from the ground, I grabbed his arm and could feel that there was no trace of anything in his shirt.
Put on other clothes."
Xu Tiannan thought: "Well, the weather is not cold now, so it's not surprising that most people only wear a shirt when going out, so..."
Xu Tiannan weighed the club in his hands, suddenly turned to Wen Sibao and said, "Fourth Master, are you ready?"
Wen Sibao was stunned and asked in confusion: "Preparation? What are you preparing for?"
In an instant, Xu Tiannan raised his club and hit the opponent. This move was very fast and hit Wen Sibao's head. The opponent immediately stretched out his arms to resist in desperation.
With a muffled "bang" sound, the front end of the club hit Wen Sibao's arm hard, and a similarly curved gap was instantly created.
"Ouch! Ouch! Ah..."
Wen Sibao put his arm between his legs and grinned in pain: "Tian Nan! You are fucking sick! Why are you hitting me! Ouch..."
Xu Tiannan did not respond, but immediately stepped forward and pulled Wen Sibao's arm out, and then rolled up the sleeves of Wen Sibao's shirt to observe.
Soon, a red mark appeared on Wen Sibao's beaten arm. Xu Tiannan immediately took out a caliper to measure it, and said to himself: "Well! The wound hit by this club will probably be a long
45mm, 7mm wide blood stain..."
"I go!"
Wen Sibao immediately withdrew his arm and responded dissatisfied: "You guys are using me for experiments! It hurts like hell... Besides! There are millions of people in Mobei City! Are you going to go to the streets and turn over people's houses one by one?
Sleeves!”
"No no no!"
Xu Tiannan responded: "Of course it's impossible! And the location where the murderer was hit by the club was not necessarily in the arm, but I know what to do now."
Wen Sibao blew on the bruise on his arm and asked, "What? Listen to what you said...do you know who the murderer is?"
"I'm not sure yet, I'll tell you later."
"Hey! Hey! Hey! Why are you so mysterious?"
When Wen Sibao saw this attitude, he immediately became unhappy! He grabbed Xu Tiannan and said, "I've already been injured at work! You're still hiding it, what did you find? If you don't tell me, I'll be angry!"
"
"That's right, it's really hard to do this without you."
Xu Tiannan said, casually took out a band-aid from his pocket and put it on the wound on the other person's arm. Then he wrote a series of phone calls on it and warned: "Check the call records of this phone number during this period.
It will be sent to my mobile phone."
"Hey? What do you mean? Why did you just leave?"
Ignoring Wen Sibao's dissuasion, Xu Tiannan took Murong Shui and left the scene.
