Chapter 349: Major Discoveries in Technical Investigation

"Captain Xu."

Chen Yi looked at Xu Wenbing.

After thinking about it carefully, Xu Wenbing still felt that Song Lishun killed his whole family, even his son...... This is too nonsense.

"Even if you have a great motive, you can't kill your son, it's really incomprehensible." He said what he really thought in his heart, "Compared to Song Lishun poisoning his family of eight, I still prefer that Fu Rongrong is still alive." ”

The ground under your feet is very large, and it is normal for the police to find no one, but it is not normal to almost wipe out their own door.

Chen Yi didn't respond, when did he speak: "Then where does Captain Xu think Fu Rongrong is hiding at the moment, why can't he find it?" ”

Xu Wenbing said: "He Deputy Branch, we are now looking for people to rely more on modern scientific and technological means, such as mobile phone number positioning, bank card activities, ID card activities, etc., but as long as the suspect gives up all modern conveniences and returns his life to before the seventies of the last century, it is still difficult to find it." ”

"At the very least, three days is definitely not enough."

What he said makes a lot of sense, and it is impossible to refute it when he is new.

The case discussion meeting is to express their opinions and not be afraid of making mistakes, brainstorming can advance the progress of the investigation, and if Fu Rongrong's body is not found at the moment, it cannot be said that she is dead.

Even if Song Lishun lied, Fu Rongrong didn't attend the dinner a few days ago at all, as long as there was no corpse, she was alive.

In any homicide case, the corpse is always the top priority, and without the corpse, anything is possible.

History has relevant cases, all the clues point to the murderer killed, the murderer himself admitted, who thought that the victim finally came out on his own, was not killed at all, and survived.

So, it is necessary to see the corpse.

To live to see people, to die to see corpses.

Chen Yi still admired Xu Wenbing, and the detachment had obviously begun to lean towards Fu Rongrong's death, but he did not follow the crowd and insisted that the evidence prevail.

This is a very theoretical captain.

Chen Yi spoke: "The analysis of the case is based on the existing clues to infer a variety of possibilities, Fu Rongrong is not dead, it is possible, Fu Rongrong is dead, it is possible." ”

"We can get such a result now: if Fu Rongrong is not dead, then she is the suspect in this case, and if Fu Rongrong is dead, then Song Lishun is the suspect in this case, do you agree?"

Everyone nodded, including Xu Wenbing.

Chen Yi continued: "So we went back to the original point and found Fu Rongrong, but the direction was ......."

Before he could finish speaking, there was a knock on the door.

"Come in." Chen Yi turned his head.

The door of the conference room opened, and Lu Yongqiang walked in, holding a stack of documents in his hand, on which were densely packed with text and photos of the scene.

"Team Chen, I've found a problem." Lu Yongqiang opened his mouth and handed over the documents in his hand as he walked towards Chen Yi.

Chen Yi took it and put it on the table without looking at it: "Let's talk about the point directly." ”

Lu Yongqiang nodded: "Okay, after technical analysis and comparison, the traces in every corner of all the rooms on the scene have been sorted out, and there are two things that are more important." ”

"First, all the plates on the table only have the fingerprints of the deceased Gong Yujuan and Tan Hong, and there is no fingerprint of the third person."

"Second, the results of the footprint analysis are also a bit strange, we carefully did a footprint coverage comparison, and determined that there were no new footprints of a third person in the kitchen, most of the new footprints came from Gong Yujuan and Tan Hong, and a small number came from an adult man."

"Team Chen and I talked about it before, and there is a ninth person at the scene, right?"

Chen Yi: "That's right. ”

Lu Yongqiang: "But we didn't find any traces of the ninth person's new activities. ”

Everyone looked at each other, and this result showed from the side that Fu Rongrong did not attend the party and did not cook in the kitchen.

Song Lishun lied.

Why lie? It's hard to say now, but the probability of Fu Rongrong's death has surged.

Xu Wenbing also did not expect this situation, his brows furrowed tightly, and he began to rethink the possibility of Song Lishun killing his family of eight.

If it weren't for the deceased's relationship with him, his suspicion of committing the crime would definitely not be small.

Chen Yi: "It's hard work, but the work is not over, gather the team with all the survey equipment, and prepare to go to the farm with me." ”

Lu Yongqiang: "Yes." ”

After Lu Yongqiang left, Chen Yi said: "Continue with the topic just now, where did I just talk about?" Oh yes, we are back to square one, we must find Fu Rongrong, but the direction must be a new extension, the person who was looking for Fu Rongrong before, now we have to add the person who is looking for Fu Rongrong's body. ”

"The two directions should be carried out at the same time, Lao He, you go to Fu Rongrong, Captain Xu, and follow me to the farm later."

Xu Wenbing ordered: "Yes, Chen Zhi." ”

It is one thing to express one's opinions in a meeting, and it is another thing to obey orders.

The team set off quickly, and this time almost all the police officers on standby in the county bureau were emptied, including the technical staff of the detachment, there were more than twenty people.

On the way, Xu Wenbing asked the purpose of the trip: "Chen Zhi, if Fu Rongrong is dead, do you suspect that the body is on the farm?" ”

Chen Yi: "If Fu Rongrong dies, there is a high probability that Song Lishun did it, he only left the hospital twice in ten days, and the trajectories of both times were on the farm." ”

Xu Wenbing: "In other words...... The first time she left the hospital, she killed Fu Rongrong, and the second time she left the hospital, she poisoned seven people in the family. ”

Chen Yi: "This is almost the only possibility, the premise is that Fu Rongrong is really dead, let's look for it, a corpse cannot disappear out of thin air, there must always be traces left." ”

The vehicle quickly arrived at the farm, this is the second on-site investigation, counting the county bureau's alarm, this is the third time.

At the same time, it will also be the most comprehensive survey, and the survey target is not only limited to the crime scene, but also covers the entire farm.

Every corner that can hide people, every inch of land that can bury people, will be swept away by the surveyors.

Everyone quickly scattered and threw themselves into the work, and Zhuo Yun was responsible for leading the team.

Standing in place, only Chen Yi and Xu Wenbing remained, the farm is not small, and it will be delayed here for a long time today.

"You go over there."

"You guys, go there."

"Qin Fei, take someone to carefully inspect the vegetable garden, as long as there are traces of movement, dig it immediately."

Zhuo Yun commanded in an orderly manner, while Lu Yongqiang led the technicians, looking for every place where blood might be left.

Looking down from above, the survey area is slowly spreading forward, and there is no omission to achieve a carpet search.

It was morning, time passed, and soon it was afternoon, and everyone had not eaten lunch, and they continued to work hungry.

It hasn't rained in the past few days, the soil is dry, if there are traces of renovation, it will be easy to find, Qin Fei has been looking for hours, but there is no gain, the suspected places have been dug up, and no corpses or human tissues have been found.

At four o'clock in the afternoon, the technical detectives came to the machinery factory area, which is the only mechanical operation room in the farm.

After the automation of breeding, modern equipment is indispensable, including feeding equipment, manure removal equipment, environmental control equipment, crushing equipment, etc., which increases the cost of breeding at the same time, and the subsequent profits are also increased accordingly.

"Block out as much light as possible and pull up all the curtains you can."

Lu Yongqiang gave an order, put on protective eyes and gloves, and personally took the trace lamp to move forward little by little.

Trace lamps are ultraviolet lamps, which are a commonly used crime scene investigation tool to detect and find bloodstains.

By emitting ultraviolet light, blood stains fluoresce in dark places, helping investigators find hidden blood trails and providing important crime scene clues.

Iron ions are reactive to ultraviolet rays, absorb energy and emit visible light, and the color is light blue or lavender, which contrasts sharply with the surrounding environment, which is very intuitive.

As soon as a suspicious point is found, it will be further confirmed with a bloodstain detection reagent, and luminol is commonly used.

Lu Yongqiang walked very slowly, constantly adjusting the wavelength of the trace lamp, and finally came to the vicinity of the feed grinder.

Suddenly, a clear blue light appeared in sight, and the familiar color made Lu Yongqiang straighten his body reflexively, and shouted in his mouth: "Bring the reagent!" ”

Hearing this, all the surrounding technical investigators quickly moved closer to this side, and when they saw the blue light that appeared, everyone's faces became solemn.

There are many forms of bloodstains.

Splash, splash, drip...... There were, and there were even pools of blood.

As a rule of thumb, the most likely occurrence of a bloodstained form is the destruction of the corpse.

Since the bloodstains appeared near the shredder, the possibility of dismembering the corpse filled the minds of the technical detectives.

Just think about it, no one speaks, no one proposes possibilities, their job is trace detection, not reconnaissance and analysis.

Several people began to spray luminol reagent along the route of the ultraviolet lamp, and after dozens of seconds, the blue light was very dazzling, and the atmosphere gradually became oppressive.

The discovery of bloodstains means that the missing person Fu Rongrong should have been killed.

Another human life, this is the eighth deceased.

As time passed, more and more residual blood stains appeared, especially inside the crusher, which was even more shocking, and Lu Yongqiang even saw hair, and objects that were suspected to be human tissue.

"Crazy case."

Lu Yongqiang muttered to himself in his heart.

Cases of corpse mutilation are extremely rare, not to mention that there are seven other deceased, but it is not known whether the deceased in front of him and the seven deceased who were poisoned are the same murderer, this point is not 100% certain.

The small Pingxian County is afraid that it will be famous in the provincial department, and if the case is made public, it will be famous in the whole country and even the world.

There is also the question of how the murderer dealt with the body after it was dismembered.

At the foot is the farm, Lu Yongqiang inevitably sprouted the judgment of feeding, in front of him is the feed grinder, and the things that come out of the feed grinder are naturally "feed".

He has been in the industry for many years, and he is also chilling at the moment.

"Report to Team Chen immediately, go quickly!!"

Lu Yongqiang spoke in a deep voice.

"Yes!"
