I'm not a super cop

Chapter 379 New Discovery
After the task was assigned, Liu Qing, He Liang, and Song Zhiyi who came over followed the information they found on the Internet to find the organizers of the cross-country race on May 5 and learn about the relevant situation.

Together with Zhang Lei, Xiao Ran is going to Wanggong Mountain to investigate the site again.

But just as he was about to leave, Yu Yu chased after him with a forensic box, "The vegetable market, let's go to the vegetable market first! I'm going to buy something and put it on the spot for experiments."

"What do you buy at the vegetable market? If you are doing an experiment, you don't have anything in the laboratory, so you still have to go to the vegetable market to look for it?" Zhang Lei turned to the vegetable market and asked puzzled.

"Meat, there is no meat in our laboratory!" Yu Yu said, sighing resentfully: "It's a pity, I finally went to the vegetable market, and the meat I bought can't be eaten by myself..."

"You bought the meat to test those fly larvae, right?" Xiao Ran asked looking out the window.

"Yes, yes." Yu Yu nodded like a chicken pecking at rice, happily took out a medium-sized ziplock bag from the box, and kept shaking it in front of Xiao Ran: "Look, look!"

Xiao Ran turned his head, and immediately saw those fat maggots that were about to touch his face, which were clumped together in a ziplock bag!
"I'll go, what are you doing with these?!" Even Xiao Ran, who has always had an excellent mental quality, was taken aback when he suddenly saw these densely packed little things that were about to touch his face.

Zhang Lei, who was driving, saw these and yelled: "You perverted girl, you bring these things to the vegetable market, you don't think it's disgusting!"

"I didn't bring these to help you handle the case!"

Yu Yu glanced at Zhang Lei, pointed to the mass of fresh and fat maggots in the bag, and explained: "These are the best-developed larvae I picked from the dead body, and after my observation yesterday, there were no dead maggots at the scene. Broken chrysalis, which shows that none of the maggots on the dead body have turned into flies."

"And then?" Zhang Lei grinned, forcing himself not to look at the things in Yu Yu's hands, otherwise the breakfast he had just eaten might be thrown up in the car!

O maggots picked from the dead!
That's the girl who can do it.

Thinking of the intensive situation on the body of the deceased yesterday, Zhang Lei's scalp became numb, especially when he thought of:
——In the middle of the night, Yu Yu looked down at the corpse, carefully picked out such a group of maggots one by one with tweezers, and then raised his hand to shake the fleshy and soft worms, and said with a smile, " Perfect'!
Can't think, can't think...

"We did research last year. You must know that among insects destroying corpses, fly maggots are the most common, and flies are very sensitive to corpse odor. Sometimes they can even gather when the organism is dying. to the surface of the organism to start spawning.

After the fly eggs hatch, they will secrete a liquid containing proteolytic enzymes. The first thing they have to digest and destroy is the soft tissue of the corpse, especially the fat in the abdomen, and then invade the subcutaneous muscles and internal organs.

The most common fly species in the area, in summer, the fly eggs usually hatch into larvae after 12-24 hours, and then turn into pupae after 5-7 days, and the pupae break out into flies after 3-5 days. "

Yu Yu put the larvae back in the bag, "These are the best-developed batch of larvae, I put them on the site together with the meat, and observe regularly that it will take a few days for them to turn into flies.

After confirming this time difference, I will cultivate two groups of fly eggs outdoors and in the laboratory, compare and observe the time it takes for the fly eggs to grow into these larvae states, and then calculate after excluding interference factors, and then I can get a more accurate estimate of the death of the deceased. It's time. "

"Admiration, admiration, although I don't understand what you said, but I think it's amazing!" Zhang Lei joked.

Xiao Ran had been silently listening to Yu Yu's experimental ideas, and suddenly asked: "But if you do this, wouldn't it take a long time?"

"It will take ten and a half months."

Yu Yu thought for a while, and said, "But this is just a bottom-up experiment, just in case. In case you can't figure out the situation in a short time, then with my experimental results as a basis, maybe it can provide you with a lot of information. Big help."

"But you know, we, Xiao Ran, always handle cases very quickly. If you haven't come out with the result, we have already solved the case. Wouldn't your work be in vain?" Zhang Lei said with a smile.

"It's better to be busy for nothing than to ask me for data when the time comes, but I can't come up with the results?"

Yu Yu didn't care, but after another thought, she looked at Xiao Ran and said, "That's right, I haven't seen a case in your hands that lasted more than half a month. ——Hey, if you hurt me If you are busy for nothing, you have to treat guests to dinner!"

"What do you mean I make you work in vain? I'm not a god. Besides, I can't handle the case by myself. Why don't I rely on your help."

Xiao Ran glanced at Yu Yu, "But what you said is pitiful, so let's do it this way, if the case can be solved before the results of your experiment come out, I will treat you to a big meal, the kind with a lot of meat!"

"That's it!" Yu Yu cheered.

While talking, Zhang Lei drove to a vegetable market on the way, and the vegetable market in the morning was crowded with people.

It took a lot of effort for Yu Yu to pick out a large piece of pork that was more fat than thin, and then asked the shopkeeper to divide the meat into three evenly, then returned to the car and headed to the scene of Wanggong Mountain.

On the side of the road at the foot of the mountain, an assistant policeman dozed off in the car. Zhang Lei parked the cars side by side, and went straight up the mountain without disturbing the assistant policeman in the car.

Next to the warning belt on the mountainside, there was also an assistant policeman guarding the scene. The three greeted him and then crossed the warning belt and entered the scene.

It has to be said that the daytime atmosphere at the scene was much better than last night, and after the corpse was removed, after a night of air circulation, most of the stench dissipated, only a little stench remained in the pit.

After helping Yu Yu down to the bottom of the pit, Xiao Ran and Zhang Lei began to survey the periphery of the pit again. Their attention was all around the pit last night, and this time they want to expand the scope of the survey.

Taking the place where the deceased fell as the center, Xiao Ran and Zhang Lei spread out. The bushes and weeds near the pit were all trampled down yesterday. It is easy to check, but further away, there are overgrown trees and trees. Little by little, weeds and bushes were carefully inspected.

"I found something! Xiao Ran, come over and have a look!"

There was a shout from Zhang Lei, and Xiao Ran walked over immediately, and saw a pebble-shaped blue stone with many edges, the size of two steamed buns, quietly embedded in the soil beside the grass.

The most important thing is that there are mottled bloodstains on one side of this stone, and a bloody handprint on the other side!

After Zhang Lei took out his camera to take pictures, he carefully put the stone into the evidence belt, and said excitedly: "This must be another murder weapon. The dead man's finger may have been broken by this stone, and it may still be extracted from it." The murderer's fingerprints!"

Xiao Ran nodded, looking at the small hole left by the stone on the ground, "It should have been thrown over by the suspect after committing the crime."
