Back in the office, Jiang Liu organized everyone to discuss the next direction of the case.

Gen Hao took the report belatedly, "The results just came out, the female deceased was about twenty-five years old, between 1.65 and 1.68 meters tall, weighed about 50 kilograms, had a plum blossom tattoo on her left ankle, did not encounter sexual violence before her death, there were more injuries on the surface of the body, mostly abrasions, it should be caused by the villagers when they removed her from the coffin, there are many possibilities for the cause of death, she had blunt force blows to her head, which caused bone cracks, but this is not the fundamental cause of death, the dissection found that the victim had multiple organ failure after intracranial infection, This takes a certain amount of time, and it is considered one of the joint causes of death, and the direct cause of death is ......"

"Suffocation." Wu Dao, who was silent, suddenly spoke.

Nechi and the others present were stunned, and it took him a moment to affirm, "That's right, how did you know?" ”

"Wait, you mean the deceased survived for a while after being seriously injured?" Guo Rebellion interrupted.

Wu Dao dragged his chin in contemplation, staring at one part of the room with empty eyes, and his brain was rapidly constructing the simulated scene before the woman's death.

"The victim's living environment should be relatively favorable, her hands are neither rough, nor have her knuckles thickened because of housework, she should have done frequent hand care before her death, she had just done nail maintenance before she died, and the little finger and ring finger of her left hand are layered with nail polish glue residue from French manicures, you can see that her nails are three short and two long, showing uneven wear, which is a bit abnormal for a person who pays attention to hand maintenance."

"That's how you judged?" Gen looked at the report, "We have a record of this, and it is inferred that it should be the damage caused by the resistance. ”

Wu Dao shook his fingers, "If it was caused by resistance, the cross-section of the broken nails would not be so neat, there are other reasons." ”

Chen Daming listened attentively and urged Wu Dao, "Don't sell Guanzi." ”

"I was only guessing at first, and it wasn't until I was chased by the villagers and fell into the coffin that I was sure of my previous guess." Wu Dao took out his mobile phone and opened the photo album, on which were the photos he took inside the coffin, "There are several suspicious features of the female corpse's death, her knees are bent, her upper body is leaning forward, and her mouth is wide open, all of which are very in line with the instinctive reaction of the human body in the case of extreme hypoxia, she should still be alive when she was sealed in the coffin, the slight bone crack caused by the blunt force blow to the head only made her faint temporarily, but the murderer did not have enough medical knowledge, he thought she was dead, so he put her in the coffin and destroyed the body, The coffin board of the coffin is dug from the whole cypress wood, and the murderer repaints the joints, which is tantamount to turning the coffin into a vacuum environment with excellent airtightness, and the oxygen in the coffin is very limited, so when the victim wakes up and calls for help, the oxygen is quickly depleted, which is why her body can be preserved well, because at that moment, everything is still. ”

Jiang Liu took his mobile phone and circulated it to everyone.

In the photo, the sides and top of the coffin are covered with eerie scratches, and it is hard to imagine how frightened and helpless the victim was when he woke up in a small dim space.

After reading the photo, Gen Hao returned the phone to Wu Dao, "You are right, her jugular veins are seriously distended, there is very little oxyhemoglobin, and suffocation is indeed the cause of her death." ”

"Can you tell when the deceased died?" Jiang Liu asked.

Gen Hao shook his head a little embarrassed, "Not sure, the situation is a little special, under normal circumstances, the method of inferring the deceased's commission to determine the time of death is not applicable, I can only try." ”

"Maybe it can be helpful to start with those black paints and check the age of the cracking of the coating." Wu Dao added.

Guo Rebellion didn't know when he came to him, and directly hugged his shoulder, "I can't see it, you still have two more hits." ”

Wu Dao rolled his eyes and handed a note to Jiang Liu, "The light is not good, there is a word above the coffin that is not clear."

"Female characters?" Jiang Liu muttered suspiciously.

Wu Dao shook off Guo Rebellion's arm, "I think this character should not be finished, the victim will lose his breath, the whole font is obviously tilted at a certain angle, obviously used as a radical, not a single word." ”

Chen Daming muttered, "Mom, it's the word mother, maybe I missed my mother very much before I died, so I wrote it." ”

"It could also be grandma, auntie, aunt." Guo rebelled and said a series of possibilities.

The root number is a little unbearable, "It should be related to the murderer, psychologically speaking, the most likely thing that prompts the victim to stimulate his potential and leave a mark is the things related to the murderer, family, affection, love, these things that are nostalgic exist in the mind when they are dying. ”

Wu Dao snapped his fingers, "Totally agree." ”

Twilight had arrived, and a light rain had fallen in the sky.

The pace of this day was too fast, and the atmosphere was very tense, even if it made the fledgling Wu Dao feel excited, he was also a little tired.

He doesn't smoke, so he can't refresh himself like Guo Rebellion and Chen Daming, and he is so sleepy that he yawns.

Jiang Liu roughly summarized the clues and ideas before announcing the end of the meeting.

He picked up his coat and threw it to Wu Dao, "Let's go and fill our stomachs first, and then go to the county guest house to make up for the night." ”

Wu Dao glanced at the time, it was indeed too late to rush back to the dormitory at this time, "Okay." ”

Early the next morning, there was news about the black paint that had been sent for inspection.

Since the comrades of the cultural management office have been dealing with ancient tombs all the year round, they have studied the BP of cultural relics (the limit from this year) very well, and they have come to conclusions without going through any sophisticated instruments and complicated procedures.

Song Yi knocked on the door of the office and returned the physical evidence bag to Chen Daming, "Judging from the cracking and oxidation stratification of the black paint, it will take about five years. ”

"It's about the same time as we figured it would be." Root number identification.

Guo Rebellion slapped his face, "The breakthrough is obvious, and the identity information of the deceased can be compared with the missing person library in the past five years." ”

Jiang Liu didn't agree, and looked at Wu Dao, who was indifferent, "Have you ever touched profile?" ”

Wu Dao was stunned for a moment, "A little bit, what's wrong?" ”

"What conclusions can you draw from the information available?" Jiang Liu didn't answer his question and continued to ask.

Wu Dao thought for a while, "The deceased is about twenty-five years old, although he is naked but has not been sexually assaulted, then there are only two possibilities, one is to rob money, but under normal circumstances, random crimes for the purpose of robbing money, there is no need to go to great lengths to throw the deceased into the tomb group to cover up, so it should be the second reason, vendetta or love killing, after deliberately killing someone, the victim is stripped naked in order not to leave relevant information that can prove his identity, even if the body is found, there is no way to find it." ”

Jiang Liu lit a cigarette, "I'm a little surprised by your performance. ”
