After Liu Jinghui made a statement that everyone was suspected, he was excited to pace back and forth in the room.
Everyone in Changsha knows that high IQ crimes are not desirable. The key to a murder case that can successfully escape from crime is to prevent the case from turning it into a murder case.
In this case, the murderer may have initially wanted to get the case out of the category of murder. However, Liu Jinghui was not sure about this. After all, the routine of strangling and pretending to commit suicide is a bit amateur. Anyone who knows a little should know that forensics have accumulated too much in this area, and even if they encounter a ninth-rate forensic doctor, they may not be able to succeed.
However, after seeing through the murderer's amateur routine, Liu Jinghui felt special.
This is equivalent to a double insurance structure.
As we all know, the linked insurance is more likely to occur when one breaks and one moves the whole body, let alone a murder case accompanied by fierce movements.
Making mistakes is the norm. Perfect invisibility is difficult to achieve.
Liu Jinghui took a few steps, then turned around and said, "Video surveillance can play such a great role. I need to solve the case next. I think I can start with the motivation. I think I can ask these people in the apartment in detail, so that each of them can write at least 3 people who may murder Martina..."
When Cui Qishan heard this, he didn't know what was so excited about Liu Jinghui. He glanced at the corner of his mouth: "You are playing games."
Liu Jinghui said "cough cough" twice: "We have limited understanding of them, and most of the apartments are foreigners, so it is difficult to investigate their lives. In this case, the clues can only come from confessions, asking them to write three murder suspects each to force them to report, but you can't report it openly, right, they are employees of the same company after all..."
"Okay." Cui Qishan was quite reliable when he heard what he said. Besides, even if Shannan Reasoning King is more playful, the current scene is in line with his character.
Cui Qishan called his subordinates directly and asked them to operate according to the pattern Liu Jinghui said.
Seeing that this side made it clear, Liu Jinghui turned his head suddenly and stared at Jiang Yuan.
Jiang Yuan was too familiar with Liu Jinghui's performance, so he gently picked up the coffee cup and asked, "What do you want?"
Liu Jinghui said: "We have no suspects now, so we have to update some information. Can you reproduce the crime scene?"
Jiang Yuan laughed silently: "The footprints cannot be found, and there is no blood, so it cannot be reproduced."
Liu Jinghui was a little disappointed: "I saw some things throwing in a mess on the scene, like pillowcases or something, and I can't make a judgment based on them."
"They are the culprits that lead to the lack of footprints." Jiang Yuan spread his hands.
Liu Jinghui sighed: "There is no condom or something, and there is no sweat or semen. I don't know what they are doing in the room. The simulation of sexual suffocation means that the murderer is a little familiar with Martina. He knows that she has a hobby in this area and has actually had sex?"
Liu Jinghui said and looked at Jiang Yuan again.
"There is no evidence to show that there is, but it cannot prove that there is no." Jiang Yuan expressed it quite clearly.
Liu Jinghui nodded in thought, not knowing what was going on in his head.
Seeing the difficulties he was thinking, Jiang Yuan said: "If you want to know more information in the room, you can only wait for the report of trace evidence. At that time, if you can find semen on the fabric in the room, it is the gold standard. If you find a lot of sweat, you can barely infer it."
Liu Jinghui's eyes lit up: "You have a good idea, when will their report be released?"
"It should be soon. I'll urge you." Jiang Yuan has done many cases in Zhengguang Bureau, especially in many major cases. He is an expert who has brought local criminal personnel. It is very easy to urge the report.
Liu Jinghui continued to think and asked, "What do you think now?"
"Do you eat hot pot?" Jiang Yuan looked up.
He has done everything he can do, and for him, the next step is to wait for the report.
Liu Jinghui thought about it carefully, but for a moment he could not refute it.
"Hey, Xiao Gu, I'm at Zhengguang Bureau..." Before he could come back to his senses, Wei Shizhi had already called.
Putting down the phone, Wei Shixiu smiled and explained: "I have a little brother who specializes in making copper pot mutton. I asked him to bring the master to bring the pot over."
"Okay." Jiang Yuan refused, saying, "Let him bring more pots and more ingredients, and see if Tao Zhi and others eat it."
"I understand. I'll let them open the ticket to Zhengguang Bureau." Teacher Wei didn't need to be taught by others, as if he was born with a natural ability or had attended some family tutoring class.
In a short while, the copper hot pot was filled with the canteen of the Criminal Police Detachment of Zhengguang Bureau.
This scene is familiar to the criminal police brigade of the County Bureau and the criminal police brigade of the Zhengguang Bureau. Although the two are quite different in levels, they are actually mainly in the city gap. The things they do are similar in nature, they are both in the front line positions, not as many small cases and trivial matters as police stations, and are more professional than township levels. However, as long as they rise to the level of criminal cases, they will be the life of the criminal police team.
And as long as the case is handled, there will be endless cases.
Nowadays, there are fewer murder cases, and even fewer crimes of various contact crimes, but in the number of criminal police in China, a few percent of the cases are still in a state of backlog. Once you encounter a big case, the most important thing is that once you encounter a case that the leader attaches importance to, the police who go out to handle the case must go out early and come back late.
Because of this, the canteens of the criminal police team are relatively better, especially in police stations with sufficient funds, who are still willing to spend money on food.
Although the canteen of Zhengguang Bureau is not large in size, the decoration is compact and has all the configurations that should be found. A few copper hotpots are delivered, and you can start eating after a little preparation.
Tao Lu, who was originally going home, simply stayed and had a meal with Jiang Yuan.
However, some ordinary policemen took the opportunity to evacuate.
Jiang Yuan naturally ignored these things. After Huang Qiangmin, Wei Shiqi and others greeted him, he sat in front of the hot pot, watching the clear soup rolling with ginger slices and green onion slices, while following the two cases that came this time in his mind.
Chinese people have always been very tolerant of genius figures. Huang Qiangmin and Tao Lu looked at each other. The latter waved their hands without listening to Huang Qiangmin's explanation and smiled: "We are all casual, all casual, and we don't have any wine today. We have enough to work after we have enough!"
People around him hummed and started to smack the meat.
Wei Shi consciously sat in the last place, holding the public chopsticks, put three taels of meat in one breath, and then laughed: "The mutton in this store is cut by hand, and they all come according to the ancient standards of the past. Today, I called eight masters over here, and I should be able to come here. However, the most delicious and famous thing in this store is not mutton, but frozen tofu."
"Oh, there are some specialties in frozen tofu?" Huang Qiangmin cooperated.
"Old tofu made by oneself should have low moisture content. After freezing, it should be thawed naturally and cannot be quickly removed with hot water." Wei Shixiu said and smiled: "In fact, there is nothing special. It is made according to the skills of the old master. If you don't sacrifice the taste to improve efficiency, you can make it. The taste is better than the products on the market."
The newest ⊥小⊥小⊥ said⊥⊥⊥⊥⊥⊥⊥⊥⊥⊥!
"It's rare..." Tao Lu nodded and praised, and did not talk about this topic again.
Wei Shi was stunned. He originally thought that the leader would make a high-level speech, but unexpectedly, the stage was set up and Tao Lu was not on the way. Wei Shi Shi continued to think that Tao Lu probably didn't want to regard himself as a leader at this time.
Wei Shi couldn't help but look at Jiang Yuan.
Jiang Yuan dipped mutton in sesame sauce at this time and ate it in big mouthfuls, without touching a bite of frozen tofu.
Jiang Yuan ate quickly, Tao Lu and others also ate quickly, and many people disappeared as they ate...
Liu Jinghui was old and couldn't eat much. After spending a while, he was ready to leave the table and disappear. At this time, his phone first made him a document.
"The physical and chemical report on the scene has come out." Liu Jinghui ignored the others and immediately handed it to Jiang Yuan.
"Let's take a look." Jiang Yuan reluctantly put down his chopsticks, and when he turned around, Wang Chuanxing took the pad and handed it over.
The PAD that has not been shot is particularly clear.
Jiang Yuan turned over page by page and flipped it very quickly.
The measurement of trace evidence sounds amazing, but it is not necessarily very useful in practice, especially if you don’t know what you are looking for.
Slight amounts mean that very few doses can be measured. In this way, if a piece of clothing is tested comprehensively, the result will be fiber, hair, soil, dust and metal particles, paint, pollen and spores, and various chemicals, such as cosmetics and skin care products, etc.
At this time, the difficulties that modern people often encounter occur. If you get too much information, you will often not get conclusions.
Therefore, in most cases, front-line criminal police need to find clear objects, clear locations, and point out the substances they want to find. For example, kidnapping cases look for traces of ropes from clothes, drug cases look for the existence of drugs, or forensic botany, it also requires the assistance of trace evidence.
Jiang Yuan was a little too familiar with this area, but this time, the direction he was looking for was not about spore powder or something.
What he wanted to see was that it was not in the apartment room, preferably that it was not in the entire apartment.
At this time, a string of chemical components such as CaCO, CaMg(CO), SiO, etc. came into Jiang Yuan's eyes.
Jiang Yuan immediately turned forward and indeed saw chemicals such as HCO and CHOSi.
"What is this?" Liu Jinghui held his stomach, paid attention to Jiang Yuan's expression, and saw that he was serious, he began to ask.
"There are many sources of calcium carbonate (CaCO). Let's look at these with calcium and magnesium carbonate [CaMg (CO)]...and oxalic acid (HCO), hydrochloric acid and methyl trimethoxysilane (CHOSi)..." Jiang Yuan pondered for a moment: "You can guess that oxalic acid, hydrochloric acid and other cleaning agents, and methyl trimethoxysilane is a surface protective agent..."
“What to protect?”
Jiang Yuandao: "Dry hanging stone. The exterior walls of the apartment building are made of dry hanging stone. In this way, silica is likely to be derived from quartz, not necessarily quartzite, granite, sandstone and slate all contain quartz. Calcium-magnesium carbonate is generally dolomite, and it is likely to be derived from marble, so..."
"Did the murderer climb into the apartment from the exterior wall?" Liu Jinghui quickly inferred and then said: "How did you enter? There are traces of knocking on the glass. Martina's room window was sure that it was not pried before. So Martina let him enter? Why? Or, you can not enter from Martina's room and first enter a certain corridor or other room..."
Although Liu Jinghui mentioned all the possibilities, he was not in a hurry. He took out his notebook and recorded it: "Check whether there are any signs of prying open from the outside. Ask all residents whether they have good windows and whether they hear strange noises after the early morning. In particular, if anyone has had similar experiences, families with teenagers should pay special attention. Foreigners like to play this... In addition, people who are capable of climbing the wall, especially foreigners, should look for it."
"Do you want to consider the possibility of burglary?" Cui Qishan whispered.
"I have actually considered it before. This case is not for money." Liu Jinghui shook his head decisively and said, "It is no longer an Oriental Train murder case. Someone pulled into the train and found his way into the apartment. The case was basically solved!"
