After examining the corpse, Peng Sijue pointed to a place and said to Lin Qiupu: "There are signs of struggle on the ground here, and there are a lot of blood stains around... Look here, there are two circular marks, which may be left on the knees."
Lin Qiupu nodded, "The murderer should have pushed the deceased down here, smashed his face with a stone, causing his death, and then dragged it over there and placed it with the female corpse... Is the time of death determined?"
Peng Sijue shook his head, "It's too cold here, you can't be sure with the corpse spots alone, you have to go back and take the liver temperature... How do people plan to take it back?"
"It's not easy. Call a helicopter from the headquarters."
Lin Qiupu called immediately, then walked to the side of the cave and looked down. The bottom was a deep mountain and old forest. The murderer was most likely to throw away the things related to the case, and it was like looking for a needle in a haystack.
He said to the person in charge: “I’m sorry to ask you one thing, hire a few migrant workers to look for evidence below, and we will come out with the money... Please also cooperate with the comrades at the local police station.”
The police said: "We have an unshirkable responsibility for human lives."
Lin Qiupu asked the person in charge again: "Does this place usually accept tickets?"
"Not for this season."
"Why?"
"Police officer, you don’t know. Nobody will come to this place. In the spring, when the peach blossoms are blooming, there will be some self-driving people who will come to have fun. There will be tourism activities at that time. After autumn, the mountains will be bare. Yes, it's so cold again, who is coming? Even if the tickets are collected, it is not enough to pay for the labor costs."
"It's free and open?"
"Yes, but those who will come here are all mountaineering enthusiasts."
Speaking of mountaineering enthusiasts, the person in charge took a look at the accompanying college students. The college students said: "Several of us are mountaineering clubs, and we often organize mountaineering activities. The team members often say that you should never be unfamiliar with climbing outside. People form a team together, and there may be some kind of money and sex in the deep mountains and old forests. This kind of thing has happened before, and the police can't break it... Oh, sorry."
The speaker was unintentional, and the listener was intentional. Lin Qiupu frowned and thought. The police are not afraid of complicated cases, but simple ones.
This kind of case is the most difficult to solve when a person runs into the street and kills a person without warning. If this kind of casual indiscriminate murder takes place in the mountains, it is even more difficult.
"Then... Is there monitoring at the entrance?" Lin Qiupu asked again.
The person in charge smiled and shook his head, "In the mountain, where is the surveillance, but there are a few restaurants that open at the intersection. You can ask."
There was a gust of wind in the air. Everyone looked up and saw that the helicopter was coming. The technical squadron stuffed the body into the body bag, tied it to the rope lowered by the helicopter, and slowly hoisted it up.
The college student saw a police helicopter for the first time and took out a few pictures with his mobile phone. Lin Qiupu said, "Don't take pictures, delete the pictures."
"Sorry!" The college student smiled.
The body was transported away, and everyone returned the same way. Lin Qiupu asked Lin Dongxue to talk to the group of college students to see if there were any clues left. He sent a few people to look for witnesses nearby, and he went to communicate with the local police station. .
Lin Dongxue asked, "Would you like to call Chen Shi."
"Don't look for him first, count on him for any case, what have we accomplished... Besides, this case is no better than the previous ones, and he can't help but solve it."
"Oh well!"
The on-site forensic work was over, and it was past noon. Everyone had a meal together in a small restaurant. After returning to the bureau in the afternoon, Peng Sijue started the autopsy work, and Lin Qiupu and Lin Dongxue also came to watch the forensic laboratory.
The body has been dissected, and Peng Sijue said: "The time of death for women was about seven days ago. For men, it seems to be a little later, from three to twelve hours."
"Can't it be more accurate?" Lin Qiupu asked.
Peng Sijue shook his head, "The cave is very cold and there are no insects in this season. All of our methods cannot accurately predict the time of death."
"You keep talking."
"Women are around 23 years old, and men are around 25 years old. The injuries on the female face are caused after death. The real cause of death seems to be poisoning. Her liver and kidneys have obvious signs of poisoning. A pinhole was found behind his left shoulder blade, which was pierced through the clothes..."
"let me see."
Peng Sijue showed the eye of the needle to Lin Qiupu. He said: “Because the female deceased was thinner and had thinner muscles, the needle was crooked after being inserted, but overall, this angle cannot be pierced by himself.”
"What poison?"
"Still in the laboratory test, I found that her heart was failing. The cause of death was most likely the heart failure caused by the poison. The target of this poison should be the cardiopulmonary system."
Lin Dongxue said: "The two wore the same mountaineering suits, maybe they were really killed in love... It's just that a murderer broke in and killed them in the process of their love."
Peng Sijue said: "This is impossible to prove. The calluses on the palm of the male deceased and the talcum powder on his fingertips prove that this person should love mountain climbing. As for whether he came with the deceased female, it is unclear. ."
"What else do you find?" Lin Qiupu asked.
"The male deceased suffered serious injuries to the face and bones and ruptured eyeballs, but this was not the cause of death. The cause of death was suffocation caused by a ruptured blood vessel and blocked the trachea. The death process may have lasted for more than an hour. After the murderer started, the deceased was actually alive. There, he died slowly in a half-conscious state."
Hearing this, Lin Dongxue couldn't help frowning, this kind of death was too painful.
Peng Sijue continued: "By the way, the stomach contents of the two people show that the last meal of the female deceased was ten hours before death, and the last meal of the male deceased was two hours before death. The two people ate completely inconsistent. The male deceased seemed to ate during the climb. Chocolates, compressed biscuits and energy drinks. It can be said that the dead female went up the mountain on an empty stomach and never even drank a sip of water."
"It takes four hours to climb that mountain, and you don't even drink saliva on the road?" Lin Dongxue was a little surprised.
"It seems that these two people are not together, otherwise, why would the food be so much worse?" Lin Qiupu asserted.
"This can only be regarded as circumstantial evidence."
"Are there any female deceased..."
Peng Sijue knew what Lin Qiupu wanted to ask, and said: "There is no sign of sexual intercourse. She is not a virgin. Also, both of them are in good health. Except for the male deceased who had a liver problem and had smoking habits, the female deceased had a slight gastritis. In addition, the deceased woman showed signs of wearing earrings, necklaces, bracelets, and rings, but all these things were missing."
"Can you restore the face of the deceased?"
"The face is broken like this, it will take time to recover."
"Okay, I'll leave it to you, let's find out if anyone has been reported missing recently."
