Xin Pet thought very well, but he hit a wall at the beginning, and Singh yelled at her on the phone: "Don't think that one is one out, you make up for Zhang Lao's shortcomings? Break your mind before it's too late, and stay in your office. ”

As he spoke, he hung up the phone.

Xin Pet has never hit the south wall or looked back, since Singh does not support her, she can only be self-reliant, so she went to the bureau leader's office by herself. The bureau leader was also open-minded, carefully read her resume, and asked her to go back and wait for news, she walked to the door reservedly, rigorously, and elitely, and suddenly turned around and added: "Leader, I can do without salary." ”

The leader looked at her seriously, slowly frowned, the atmosphere was a little awkward, Xin Pet hurriedly scratched his head and smirked, "Just kidding." The leader reviews slowly, and the leader says goodbye. ”

Out of the city bureau, Xin Pet rubbed his hands nervously, and was about to find someone to talk to, when the mobile phone rang, it turned out to be Ye Shichao.

Picked up the phone excitedly, and without waiting for her to say anything, Ye Shichao dropped a sentence: "There is progress, come to the laboratory if you want to see it, and forget it if you don't want to see it." Then he hung up the phone.

Of course I want to see it, she really wants to see it.

The nervous mood disappeared in an instant, Xin Pet started the car with a smile, and sped towards the "sound of insects".

When I came to "There is a sound of insects", I saw Singh's car parked outside the gate from a distance, and it was Ye Shichao who also called Singh. This feeling of not being left out made the corners of her mouth turn up and she trotted into the laboratory.

Ye Shichao's office is not only Singh, but also Shi Yin, the two are sitting on the sofa waiting, Singh crossed Erlang's legs, looking anxious, Shi Yin is drinking coffee unhurriedly, and Ye Shichao is sitting behind the computer with his eyes closed.

Xin Pet came in, and Singh was the first to yell at Ye Shichao, "She's an outsider, what are you waiting for her to do?"

Ye Shichao glanced at Xin Pet, his eyes were faint, and he got up and handed the prepared information to everyone, without a word of explanation. Shi Yin looked at Xin Pet, and then at Ye Shichao, smiling, "Ah Chao is a gentleman, and Miss Xin is also one of our teams." ”

"How can she be on a team with us, she's a lawyer, ah......" The latter sentence was swallowed up by a cry of pain, Xin Pet slowly withdrew the hand that twisted his arm, and also glanced at the results from Ye Shichao's hand, and exclaimed: "The efficiency is really high, it has come out." ”

It is a comparison chart of the DNA data of red fire ants in various parts of the city, not only DNA, but also fungal parasitism, and the trace elements of red fire ants have been compared with the red fire ants found on the corpses.

Ye Shichao pressed a button, closed the curtains in the office, and turned on the projector in the dim light, as simple as possible, "This is the residue of red fire ants on the corpse, this is a sample I took in the area where there are red fire ants in S City, through the cross-comparison of genetic sequences, the fire ants on the corpse belong to Fangshan District." However, considering that ant eggs and queens can be caught in the Fangshan area and raised in other areas, the comparison of insect fungi was made. A strain of Penicillium lavender was isolated from the live insect body of the red fire ant found on the carcass, which was identified as the pathogenic fungus of the red fire ant by Koch's rule. Ten strains of this bacterium were isolated from a single spor, and the same fungal infection was detected only on the samples from Fangshan area. Therefore, it can be concluded that the murderer caught red fire ants in this area and raised them in this area, and did not move across regions. ”

Fangshan District is located on the outskirts of S City, and it takes at least one and a half hours to drive from the scene of the crime.

Xin Pet frowned, "Fangshan District is also very large, and Fangshan is so far away from the park where the corpse was found, how can the corpse that was made into an anthill be transported? Raising ants and killing people are all in the same area, which means that this is the murderer's comfort zone, why did he go out of his comfort zone to throw the corpse? Longing for prosperity? But since you yearn for it, why did you choose such a secluded park? Longing for timidity?"

"The character of the prisoner does not belong to my professional category, but, when it comes to throwing corpses, ......" Ye Shichao said and switched to a page, on which was a map of the entire S City, "Fangshan District is here, the park where the corpse was found is here, if you take the national highway, it will probably be so ......far away" He drew a virtual line with a red laser pointer, and then drew it in another area, "But taking the national highway is a huge arc, if you are familiar with the path, take the path in a straight line, at most it will be half an hour." However, no matter what the path is, in order to transport the carcasses that have been made into anthills and a large number of red fire ants, two conditions must be met. One, the corpse cannot be folded. Second, there must be a specific container large enough to hold the fire ants. ”

"The area has shrunk a lot, and it's much easier to investigate. It's just, Dr. Ye, what do you mean to make another major discovery?" Singh asked.

"It starts with me. Shi Yin raised his hand, his voice was very low and good, and it could be slowed down, full of magnetism, and when it came to business, he seemed to be flirting with his sister, "As an ordinary forensic doctor in the forensic center of the city bureau, the first corpse I took over was a poor man who had his eyes gouged out and his lips cut. Miss Xin should know. ”

Of course, Xin Pet knew that he was talking about Fei Dehai, and it was yesterday, so he nodded, "I know." Does that case have anything to do with this case?"

"On the surface, it is indeed two cases that are not related, but when the autopsy was performed, I found a small sandbag in the stomach of the corpse, and when I opened the sandbag, I found that it was an egg, because I was not sure what kind of egg it was, so I showed it to Ah Chao, and the result was ......" Shi Yin said here and sold a pass, his eyes patrolling the faces of the unaware Xin family brothers and sisters.

Singh became anxious and grabbed the conversation, "Could it be the eggs of the red fire ants?"

Ye Shichao nodded, "It's the eggs of the red fire ants." ”

Xin Pet felt a chill down his spine, a kind of creepy that he had never experienced before, and the base of his tongue was a little stiff, "This...... Nor can it be concluded that the two cases are related......"

"Yes. Ye Shichao looked at her, serious and serious, "So I sat for genetic testing, and it turned out that these eggs belonged to the same nest as the red fire ants in the Ten Thousand Ants Devouring Case." I once told you that red fire ants have special supergene variations, which contain more than 600 genes, including two variants of B and b, just like the X and Y chromosomes in the human body. Worker ants with B mutation can only accept one queen with BB gene, while worker ants with B mutation can accept hundreds of queens with Bb gene. Therefore, there is a strange scene in the anthill of the red fire ant, that is, some anthills have only one queen, and some have hundreds of queens. These eggs are the eggs that are born after other queens in the same colony have been separated from each other to establish a new colony. They all have the same B-mutant supergene. ”

Singh stood up, "Is it the same criminal? But how can the modus operandi be so different? It is untenable to say that it is a serial murder case." ”

Regarding Singh's view, Xin Pet agreed, although there have been serial murder cases with different methods in many cases in ancient and modern China and abroad, but there is a certain connection in these cases, or the gender of the deceased, or the occupation of the deceased, or the clothing of the deceased. And the only point of contact in these cases is the red fire ants.

It's just that after killing the first victim, the murderer spent so much effort and a lot of thought to create such an iconic corpse, and he will definitely not give up so easily. So was Federhead's death an accident? An accident that the murderer himself did not expect?
