my love letter is always guilty

Chapter 42 042 Dark Night Dawn

"What's the deal?" A careless voice sounded at the door.

Everyone looked over and saw a very young man in white leaning against the door, holding a stack of materials similar to reports in his hand.

The newly transferred forensic doctor - Wei Shili.

"Flowers come out of play?" Li Changan walked towards him, the irritability just now subsided a little, he had a little expectation, hoped that this bastard would give him something new, otherwise he would definitely strangle him to death on the spot , Throw it back to the technical department.

Wei Shili walked in lazily, threw the report on the table, looked at the pig-like eyes of the people in front of him, and sarcastically said: "You want to close the case before the forensic medical certificate comes out? It's really a raging nest."

This kid is really annoying, Zheng Tao twitched his eyebrows, and said a little annoyed: "Didn't you say that the utility blade was the murder weapon? The deceased had no other trauma, and the fingerprints were only from the deceased and the deceased's ex-boyfriend. What can be identified..."

"Shut up!" Li Changan and Wei Shili shouted at the same time.

I rely on... the synchronization rate is so high, Zheng Tao thought he was blind. He almost got into a fight when they met the day before yesterday, but today they are united.What two freaks.

Li Changan and Wei Shili looked at each other, as if seeing shit, they immediately took a step back.

Wei Shili spread out the report sheets one by one, took out the cotton swab in his pocket and bit it diagonally in his mouth, with a frowning look on his face.

"Look at the picture above. There are two incisions on the wrist. I have already said something about it last time. In the anatomy room, I identified it again. The deep wound is very deep, the wound is neat, the margin is smooth, and the veins The incisions in the arteries and arteries were very clean, and this was done with a sharp knife."

"Isn't this nonsense?" Li Changan said contemptuously, seeing the hair on the back of his head curl up discordantly, curling up into a kaleidoscope, which made it difficult for people with obsessive-compulsive disorder. This kid's housekeeping must be a mess The mass grave perfectly matches his bum-shaped appearance.

"Don't fucking interrupt me." Wei Shili gave him a hard look, and continued: "Look at the line diagram of the depth of the wound, does it look like a concave arc?"

Looking at the screenshots of Wei Shili's finger, the wound was of different depths from the beginning to the end. The shallow part was the two ends of the wound, and the deep part was the artery, like a crescent moon.

Li Changan took a breath of joy, slapped the report, and suddenly realized: "The murder weapon is a curved blade!! Not a straight line of art blade!"

The others stared wide-eyed in shock, and rushed forward to observe, but they saw Li Changan's very huge palm covering Wei Shili's hand, blocking the entire picture.

"Captain Li..." Liao Xin pointed at Li Changan's hand and said awkwardly, "Have you shake hands with Wei Fayi yet?"

Li Chang'an and Wei Shili lowered their heads at the same time, with ghost-like expressions, quickly withdrew their hands, each found a piece of paper and wiped it violently, as if they were afraid of catching bird flu.

"Oh...if the deadly weapon wasn't a utility blade...the case would be complicated." Zheng Tao worried after seeing the pictures, "We didn't find the second murder weapon at the scene. The kitchen blades were all fingerprinted, and only the owner of the house Tian Dong's is not Fang Ze's, which means that the real murder weapon is not at the scene!!"

"No." Liao Xin said solemnly: "This is murder. Could it be a curved kitchen knife? After Tian Dong killed the deceased, he washed the blood and put it back in the kitchen. This is a chess game... ..."

"Hahaha..." Li Changan laughed loudly, he felt that Liao Xin's serious reasoning appearance was a bit like a second-school patient.

"Pfft..." Wei Shili couldn't help laughing, and still looked at these people like pigs.

The two started to sync up again... Zheng Tao was stunned, not knowing what they were laughing at, but the two of them were still laughing when they were studying the case so seriously.

"Did I say something wrong?" Liao Xin blushed a little from their laughter.

Wei Shili thought the policewoman was a bit cute. He stopped laughing and explained: "The depth of the wound is 1.7 centimeters, which can produce such an obvious effect. This murder weapon is single-sided, with an angle of 25°-30°. , the thickness of the knife is about 5mm..."

He pointed back to the first picture and said: "This wound is clean across the board. The arc-shaped blade saves friction, and the force is applied to the tip of the knife to cut the wound cleanly. It's just that the posture of holding the knife needs to be more professional, because It's a saber."

Although he looks like a fool on the outside, the way this kid analyzes and appraises is quite convincing, and there is a quick, ruthless and accurate energy in his bones.

Li Chang'an hates this kind of duplicity person, he is too good at disguising, but he does not deny the correctness of the facts, he walked over to Zheng Tao and asked: "Tian Dong's family has knives with similar characteristics, such as trident survival in the wild. A knife or something?"

Zheng Tao shook his head: "No, just two ceramic kitchen knives, which don't meet these characteristics."

Wei Shili raised his head and saw that Li Changan was a little bit unexpected. This idiot is quite perceptive, but he is too fucking virtuous.

"Can't it be a sword?" Xiao Yuan asked suddenly while writing the record.

Li Changan rolled his eyes, and said angrily: "Who the hell is so unconventional and wants to drag a sword to cut his wrist? Afraid that others won't remember him? Or go back to the manga exhibition for cosplay?"

"Haha..." Several people laughed.

Xiao Yuan lowered his head with his ears red, wishing he could burrow into the ground.

"Captain Li." Hu Feifan came in hastily from the outside: "After I received a call from the Physical Evidence Division, I went for a run. Take a look at this."

He took out three evidence bags and a report.The first evidence bag contained silvery shards, the second contained a lump of chewed gum, cold and stiff, imprinted with the key empty, and the third was a thick piece of wire.

Li Changan looked at it, and asked with a serious face, "Where did you find it?"

After taking a sip of water, Hu Feifan said: "On the shed of the small shop on the first floor of the community, colleagues from the Physical Evidence Department left things on the spot, and they found them when they went back to pick them up." Hu Feifan looked at the report and continued: "The silver debris is tin foil. "

This is a shocking key clue, Li Changan pulled the collar button on his neck, his eyes were filled with strange excitement.

Chewing gum and tin foil are common items for picking locks and slipping doors. They are very effective for A-level locks with weak anti-theft functions. Chewing gum and iron wire are easy to operate, even a three-year-old child can handle it.

"Where are the fingerprints on it?" Li Changan asked.

Hu Feifan replied: "The fingerprints belong to the deceased Fang Ze."

Flipping through the bag of tinfoil scraps again, Li Changan found something was wrong, and asked anxiously, "Is there only scraps? What about the rest of the tinfoil? Can the scraps scan out fingerprints?"

After reading the report carefully, Hu Feifei shook his head and said, "No, no complete tinfoil was found, and there were no fingerprints on the scraps."

The cloud that had just been cleared was covered with smoke again. Li Changan frowned in thought, and said to himself: "Now I can be sure that Fang Ze used chewing gum combined with a wire to pry open Tian Dong's lock and entered the house. It stands to reason that the kind of A The super lock can be opened by one of the methods, if it is for safety, he brought two kinds of materials, then after unlocking, he should also throw them away together, why only throw away the chewing gum and iron wire, but the tinfoil is gone.”

"The scraps of tin foil are stuck to the chewing gum." Wei Shili said while watching for a while.

Hu Feifan looked at him in surprise. This was exactly the information he was going to report. It was rare to see a forensic doctor so flexible and keen.

As if enlightened, Li Changan slapped his thigh with a slap, and realized: "No wonder no fingerprints or traces of picking the lock were found on the door lock. The door was opened twice. The first time was tinfoil, which left traces in the door opening Debris, the second time is chewing gum, the fingerprints and tinfoil crumbs from the first lock are stuck on the chewing gum, and the only doubt is... where is the tinfoil?"

After listening to this, Liao Xin said with great emotion: "Blessed by God, this kind of thing is thrown on the shed, and it is usually ignored as garbage. The colleague of the Physical Evidence Department really opened his eyes and found this."

Hu Feifan explained: "What he didn't realize was that the proprietress of the store yelled at her when she was cleaning the shed, saying that she only cleaned it the first day and found it again the next day, which attracted the attention of the colleague. In the room of the murder case, with the mentality of casting a wide net, he twisted a bag of garbage back to the department."

"Well, this attitude in handling cases is commendable." Li Changan praised.

After comprehending the information, Zheng Tao analyzed: "At present, judging from various evidences, this is murder. There is no doubt that the deceased sneaked into the rented house of the suspect Tian Dong without authorization, and took a leisurely stroll at Tian Dong's house with snacks. This kind of behavior angered Tian Dong, so Tian Dong killed the deceased in a fit of rage, and then faked the illusion of suicide, the murder weapon should have been destroyed by him."

"Heh..." With a chuckle, Wei Shili questioned: "Have you all forgotten about the deceased's drinking? He drank a catty and a half of baijiu, so you don't care about this factor?"

Several people started to fog up again. Li Changan liked Wei Shili's question very much. He raised his hand and said calmly, "Tell me, how is the corpse? Last time you said there was something in the water and the smell, didn't you?" Any clues?"

Standing up and clapping his hands, Wei Shili walked with elegant steps, like Lingbo's micro-steps. He floated to the whiteboard, pasted the autopsy information on the whiteboard, and said in a soft tone: "The smell can be passed, then Things have no reference, let me talk about the situation of the corpse first...

After alcohol enters the human body, it can be absorbed in about 10 minutes, enter the blood, and reach a peak in 60-90 minutes.20% of alcohol is absorbed by the stomach, 80% is absorbed by the small intestine, and most of the liquid is in the intestine, so after drinking, you will want to pee. The capacity of the human bladder is about 300ml. Take beer as an example. Generally, 200ml of beer will produce 320ml of urine liquid……"

"Wait a minute." Li Chang'an said impatiently: "I'm not a student in class, what are you doing talking so much nonsense, let's focus."

"Stupid!" After cursing, Wei Shili smashed the whiteboard.

Li Changan raised his head like a cow, and looked over fiercely: "Do you need me to take you to the toilet to wash your mouth?"

Seeing that the situation was not right, Zheng Tao hurriedly stepped forward to make peace and said, "Okay, can we all be more harmonious?" He smiled flatteringly at Wei Shili and said, "Forensic Doctor Wei, please simplify it a bit, Captain Li is just a bit impatient. , don't be surprised."

Really didn't want to stay with this idiot any longer, Wei Shili turned around, tore off the document, put it in his hand, and said in a blunt tone: "He drank 750ml of white wine and died without urinating once, about 400ml of wine It stays in the stomach and has not been absorbed by the small intestine, so it is speculated that the time between drinking and death is about half an hour."

Li Chang'an raised a strange smile: "It will take 20 minutes to die at the fastest. According to you, he drank a catty and a half of wine 10 minutes before cutting his wrists. He is doing acrobatics, one bottle at a time?"

"I'm fucking telling you to interrupt me!" Wei Shili gave him a glare.

Under Zheng Tao's reassurance, Li Chang'an didn't get angry at all, but wanted to hear what he could come up with.

Wei Shili stared for a long time before turning his head and said, "He must have been force-fed with alcohol, using a funnel or something, and poured it all at once."

"Forcibly pouring so much alcohol, you should be struggling, and your body will instinctively resist." This time it was Liao Xin who asked: "The corpse we saw at the scene didn't have any bruises on it, and it didn't look like it had resisted."

"Yes." Wei Shili nodded: "I didn't find any flaws. Except for the incision on the wrist, the other skin and flesh are intact. The murderer is very experienced. He can do it without leaving any traces. If I didn't find it in the water. The cause of death of the deceased is simply a mystery."

"What's in the water?" Liao Xin was very curious.

"B|Ether!" After leaving these two words, Wei Shili left the meeting room with the documents.

The rest of the people were still a little dazed looking at the figure walking away, but Li Changan's thinking was instantly opened up, like a narrow path suddenly opened up, a series of confusions were all solved, and the clues in this mess were found.

Li Changan wiped his face and walked out of the meeting room.

The bewildered Zheng Tao chased after him: "Captain Li, what are you doing?"

"Interrogate the suspect."

"Then what are we doing? Do you have any direction for investigation?"

Li Changan turned back, with wise eyes, and ordered: "You and Wu Xiao go to interrogate Dong Hai and learn more about his wife Huang Lihua, Hu Feifan goes to investigate the matter of the navy blue hat, and Xiao Yuan goes to find out what places are near Time Bar. Surveillance blind spot, close to the key mark of the parking lot!... Liao Xin checked the bar surveillance on the night Gu Qin disappeared in the bureau, focusing on the time period when Gu Qin first arrived at the bar and when he disappeared, and checked all the guests of that night one by one. Be careful, and find that there are people related to our current case, please come back for tea."

"Yes!" Several people responded at the same time.

The dark night seems to have opened the prelude to the dawn...
