After Shen Yuan finished introducing the apparatus in the experiment, he brought him to a small working room beside it. Inside the work room, there were a few microscopes and a few bottles filled with 75% alcohol containing different kinds of maggots.

Shen Yuan pointed to the bottles and said, "The larvae taken from the victim's nasal cavity and oral cavity are these three species: the golden fly, the red head fly, and the silky green fly. If there are enough of them, some of them will be killed in alcohol to measure their length, while others will be kept in specific insect cages to continue feeding for other useful information. "

"From the looks of these insects, the larvae of the red fly seem to be much longer than those of other larvae, while the silk flies are very small." Ding Wei said.

"Usually the red head flies appear on the body one day before the red light flies, and the transformed larvae produced by the red head flies appear on the second day, and the larvae gradually grow up. The tiny flies you see are newly transformed larvae from the eggs they produce, which will take about five days to transform under natural conditions. In these five days, the larvae of the red head fly have grown up a lot. "

"So, five days have passed since the death of the deceased at autopsy?"

"Using the length of a single insect species to estimate the time of death is usually much more erroneous. We need to work it out in conjunction with the red head fly and the golden fly, and we need to consider the climate factor as well. Meteorological data show that the temperature the week before the body was found was 9 – 15 ℃. Two of them were filled with fog and rain. Three days were overcast. Two days were overcast. Taking Red-head fly as an example, its length was 12.7mm, the average temperature was 13.6 ℃ the previous week, and its developing time was 75.7 hours. In addition, the time from the dead to the eggs being hatched into maggots was 20-25 hours in the early spring, so it was concluded that the time of death was between 95.7 and 100.7 hours before the autopsy. The body was found on March 18, and the time of the victim's death can be estimated to be around March 14. Because the estimated time of arrival of the adult flies at the corpse for spawning is generally erroneous, the time interval between the corpse's death is considered to be at least four days. "

"These flies are indeed magical." Ding Wei praised.

"Interestingly, the flies are at a later stage of development than the goldflies, the flies are six or seven hours earlier than the goldflies, and the goldflies have no eggs at night. We calculated the time of development of the fly, which was about four days after the death. In this way, we believe that the victim was killed most likely on the night of February 13th. "

"The interval between the deaths is at least four days. Can I take it that your data still does not provide an accurate indication of when the victim was killed?" Ding Wei said.

"You could say so. After all, insect spawning and adult growth are influenced and restricted by many factors, so the time of death is allowed to have a certain amount of time error. " Shen Yuan said, "However, when I was a Ph.D. student, I noticed that there was a red fly in Hunan that was very sensitive to temperature. The low temperature usually doesn't attract their attention to the corpse."

"Can you find any clues through it?"

"At the moment I cannot answer your question with certainty. I've had someone help me get some rat corpses from the Central South University School of Medicine. I have to do some experiments to find out. I'll let you know immediately if I can find something that will enlighten me on the case. "

"Okay, where is the piece of bug in my stomach? Did you find any useful information? "

"Careful observation through the stereomicroscope revealed that the sample sent was the broken body wall of the larva of the moth. The insect is only distributed in Xinjiang, and is a quarantine object determined by the Ministry of Agriculture and the Forestry Bureau. Its larvae eat the flesh and seeds of apples, pears, fruits, peaches, apricots and other fruits. Changsha has neither the distribution of the worm nor the production of its host fruit, and it is inferred that the victim had eaten an apple or other fruit eaten by a moth larva not long before the murder.

"Can't you identify the location of the apple in Xinjiang?"

"This is already the best result."

Which fruit store owner had a secret relationship with Ah Shuang? Would the owner of this shop know some secrets about Ah Shuang before she died? If there were no breakthroughs in other areas, Ding Wei felt that this was a direction for investigation. The question was, how was he going to find the boss of the fruit shop? It should be known only to the people most familiar with Ah Shuang. There were two people that Frost knew best. One was her ex-husband, and for the sake of their children, they were more or less familiar with each other. They should know a little about each other. Also, Chen Huan already knew that the fruit shop owner was related to Ah Shuang. Although Ah Shuang wouldn't tell him who the fruit shop owner was, wouldn't Chen Huan secretly investigate this matter?

There was a call from the court, and the court did receive the petition about Ah Shuang's request for custody of the child, and intended to take up the case in March, but when they called the client to contact the date of the appearance, they were unable to contact the client, so the case was dragged down.

Shortly afterwards, his colleague also called and told Dingwei that the police had gotten a hundred thousand dollars in loans from him. The authentication center issued a judicial opinion: the signature on the IOU and the content of the IOU are the same person's handwriting, but the content of the IOU occurred after the time of signing. The signatory first signed a blank piece of paper, and a few months later, the signatory will borrow 100,000 dollars to sign the contents.

What kind of situation was this?

When Ding Wei once again stood in front of Lin to interrogate him about this matter, he still acted as if he didn't care.

"What do we have to do with you? Have you fallen in love with Qi Menglu? "

"It doesn't matter if husband Qi Meng Lu lent you money or not. The reverse date means that you are faking. Since you are faking, it is illegal for you to ask Qi Meng Lu for money based on this kind of loan."

"So what if it's illegal?"

"Qi Menglu can sue you for extortion. Think about it, are you willing to try it on yourself?"

"Hmph, but my money-her husband really did take it." After saying that, he began to cry.

Seeing that he was crying so miserably, Ding Wei felt that the matter of borrowing money couldn't be fake. What was the problem?

"Then why don't you explain why it's signed before writing?"

"Because …"

"Why not?"

"If you don't have it, why don't you ask him yourself?"

"I heard from Kimono that he's missing."

"Hmph, he must have gone into hiding after owing a debt."

"I hope you'll behave yourself. Even if husband Qi Menglu borrowed your money, don't force Qi Menglu to return the money. I'll investigate thoroughly if this is what you said."

"Hmph, go ahead and check. Do you want my money back? Why should I listen to you? "

"Listen up, your sister has a large amount of money to settle. Do you want it to flash past you?"

"But the property isn't hers, it's Boss Chen's."

"But the property registered in Ah Shuang's name is Ah Shuang's. After the death of Ah Shuang, Chen Huan was no longer able to change her name. "

"I see. I'll listen to you. "

"And if you don't want to cause trouble for the police, you'd better disappear in a place like this."

The blissful district was an old-fashioned district, with sixteen eight-story staircase rooms. Liu lived in room 305 of the third building.

Liu was already waiting in the living room when he heard that Ding Wei was coming over. As soon as he saw someone approaching the door, he almost jogged to open it.

Although the house was only 935 square meters, it was beautifully decorated. There were many wooden cabinets arranged on the walls under the ceiling of the bedroom and kitchen, and some small but very tall wooden cabinets at corners or corners. There were drawers underneath, and shelves for holding items on top. The room was well-used and looked spacious.

When Ding Wei entered, he saw a tall wooden cabinet next to the TV cabinet filled with all kinds of awards and certificates for children. On top of the cabinet was a beautiful picture frame. Inside the frame was an enlarged picture of a child with a sweet smile on his face.

No doubt this was A Shuang's child, Ding Wei thought.
