Evidence hunting forensic 4 unsolved case code

The fingerprints that triggered the chasing alarm were collected from the gate of the crime scene, with four fingers in a row, completely in line with the original records of the "Black Widow" case.After rushing back to the bureau overnight, Tang Zhexue looked at the portraits of the suspects chasing and fleeing in the system, and his heart sank. It was Aunt Deng. recognize.

Lin Dong crossed his arms and stared at the portrait on the screen with a dark expression.

Du Haiwei recounted the case while looking at the pad: "On February [-], [-], which is the seventh day of the first month of the lunar calendar, around [-] am, the head of the village committee visited the victim's house, and when he entered the house, he saw the whole family lying in a pool of blood. , then called the police, and there were four victims in total, all of whom were male. The forensic autopsy confirmed that three of them died of hemorrhagic shock, and one died of mechanical asphyxiation. It is deduced that she is the murderer who made this murder case."

There was a pause, and then he seemed a little out of breath: "...the youngest victim is only eight months old, and is the biological son of the eldest son and daughter-in-law..."

"Slash and kill adults with a sharp weapon, and then strangle children."

Lin Dong closed his eyes and stated his conclusion without emotion.Without looking at the pad, he can still restore the blood and cruelty of the crime scene.It is not unreasonable for the police handling the case to call the suspect a "black widow". According to research, this poisonous spider not only eats husbands, but also eats children when food is scarce.

"This eldest daughter-in-law's surname is Deng?" Tang Zhexue still couldn't believe that the kind and gentle old lady could commit such a horrific tragedy.

Du Haiwei turned back a page of records on the screen, raised his eyebrows slightly: "No one in the village knows her name, and the investigators confirmed through interviews that she was bought by the victim's family to be the eldest son's daughter-in-law."

Sighing silently, Tang Zhexue asked, "What do the villagers usually call her?"

"People in the village say that she doesn't stay out of the house, and the three members of the old Tang's family take turns to work in the field, making sure that one person is watching her at home." Speaking of this, Du Haiwei frowned and smiled, "Yo, deputy Tang, it's still your family Son, maybe they were relatives 500 years ago."

"I don't have such relatives!"

Tang Zhexue pouted angrily.The sale of women and children has always been a serious crime, but in the 90s, there were as many such cases as a cow's hair.There are still several missing persons cases piled up in the office of the cold case team, suspected to be the work of traffickers who abducted women.They are all poor and troubled, and they can't marry a daughter-in-law in a serious way, so they have to buy one at a low price. Some buyers owe huge debts for this.

It’s not that no one cares, it’s that there’s no way to control it. Going back 30 years, the police dared to rob other people’s wives, and the old and young men in a village fought with them—they were all grasshoppers on a rope. If you buy it, I will buy it. Yours was taken away by the police, wouldn't mine be lost too?Moreover, many women simply cannot return to their original homes due to childbirth or other reasons. The victims themselves do not stand up, and it is even more difficult for others to intervene.There really were those who were picked up by the police and came back by themselves within two months.

I was thinking of staying up late in the middle of the night to refresh my spirits, but in the end I put my hot face on my cold butt. Du Haiwei lowered his head and coughed lightly, and continued: "The murder weapon left at the scene is a hatchet with the fingerprints of the assailant on it." , which is exactly the same as what the Donggang branch extracted this time."

Lin Dong put his hands on the back of Du Haiwei's swivel chair, bent slightly to look at the pad in his hand, and asked a question: "She is a weak woman, how can she subdue three strong men?"

"The autopsy showed that the deceased was in a state of drunkenness. It can be said that he had no power to resist. The blood splatter pattern at the scene also confirmed that the victim and the murderer did not have a scuffle. They were all killed by a single knife." Du Haiwei quickly swiped through several photos of the scene, There is Zhang Xiaobao's in it, and he strokes the fastest, "I am more puzzled, why did she kill the child together, and the child did not make a mistake."

Standing up straight, Lin Dong raised his eyes to meet Tang Zhexue's regretful gaze, and sighed softly——

"Then she has to ask herself."

—

In order to be sure, Lin Dong coordinated the criminal investigation team of the Donggang Branch to secretly obtain Aunt Deng's fingerprints on the grounds of the investigation of Hua Jiumei's attack.The results of the second fingerprint comparison show that the suspect in the "Black Widow" case is the woman named Deng Mei.

When the unsolved crime team went to the house to pick up someone, the old man’s reaction was even more violent than Aunt Deng himself. He held on to Tang Zhexue’s arm and kept saying, “You’ve arrested the wrong person! You’ve arrested the wrong person!” .Not bad, let's not mention the fingerprints, just go back to the DNA of a pair of children.At that time, DNA testing was relatively difficult. Only Beijing and Shanghai had testing institutions in the country, and there were no comparison samples, so although the forensic doctor took the test materials, they did not send them for test.Before coming, Lin Dong had notified the place where the case was reported overnight, and asked them to express the inspection materials that had been dusty for nearly 30 years, and they should be able to arrive the day after tomorrow at the latest.

Facing the young police officers, Aunt Deng didn't say a word, she just put on her clothes, took care of herself and went out with them.The old man cried until he knelt on the ground, looking as if the sky had collapsed, neither Yue Lin nor He Lan could pull him up.Every time Tang Zhexue saw such a family member, his heart felt as uncomfortable as a needle prick.Back when his second uncle, Tang Hua, was arrested on suspicion of money laundering, his father, Tang Kui, was there when the Economic Investigator of the City Bureau went home to pick him up. The hospital put in a brace.Urgent, really urgent, his father has been working for so many years that the police can't handle the excitement, let alone ordinary people.

Worried about the sudden cardiovascular and cerebrovascular emergencies at the old man's age, Lin Dong arranged for Yue Lin to stay with him at home, and waited for relatives and friends who could take over to arrive before leaving.He Lan has to go, the female suspect must be accompanied by a policewoman.To say that the girl He Lan is really careful, she took out Aunt Deng's reading glasses and put them on before leaving.

Back at the bureau, Lin Dong didn't rush to interrogate, but first arranged Aunt Deng into the detention room.Just after it was announced that she was arrested on suspicion of intentional homicide, Lin Dong didn't see the slightest panic in her eyes, but only endless loss and regret.

After completing the detention procedures, Tang Zhexue stared at the word "Deng Mei" signed on the document, feeling really uncomfortable.Unexpectedly, really unexpected, a woman with such a gentle appearance would be so cruel, even her own child would not be spared.He almost couldn't bear it just now and asked the other party, "What did you think when you strangled your son to death?"——A tiger's poison does not eat its child!

My mind is complicated and I can't sleep.After six o'clock in the morning, Tang Zhexue went home to walk the dog and feed the cat, and then returned to the bureau for a morning meeting.At noon, I finally couldn't stand it anymore. I fell asleep in the rest room, and was woken up by Lin Dong after not sleeping for a long time, saying that the person from the place where the case belonged had arrived.

Two people came over there, the elder named Fu Manjun, who was still a rookie in the police force at the time of the incident, and is about to retire now.The young one is called Peng Bo, who is about the same age as Yue Linwen Yingjie and the others, and is Fu Manjun's apprentice.They also brought test materials, which have now been sent to the forensic office for testing.

Fu Manjun said that he did not expect to see the result of this case before he retired.This is an unsolved case concerning his master, his master's master, and himself, three generations of police officers.It is no exaggeration to say that because of this case, he had the opportunity to be transferred several times but did not make up his mind to leave the criminal police team.He was a police officer who witnessed the scene. He said that he would remember the tragedy until his death.Especially that little baby's body, when he was a young man in his twenties, he couldn't help but get red eyes when he saw it.

Wen Yingjie arranged for Wen Yingjie to take them to the guest house, and Lin Dong went to Qi Ming with the autopsy report.In fact, there is nothing to be picky about. I don’t know how many people have turned over this case. The paper slips in the original file that record the thinking of solving the case can be bound into a Chinese textbook.It's just that this is his habit, after discussing with Du Haiwei about the on-site investigation and physical evidence analysis at night, he will come to Qi Ming to talk about the autopsy report.How the murderer treats the corpse after the murder can truly reflect the TA's psychological state at that time. It has been thoroughly studied and is very helpful for the interrogation work.

Knocking on the door and entering the room, Lin Dong felt that today's forensic office was a little brighter than usual—as if Qi Ming was shining.

——Ha, it seems that Comrade Luo Nangua guards the clouds and sees the moon.

Hearing the movement, Qi Ming turned around, thinking that Lin Dong came to urge the DNA report: "Gao Ren is doing it. The maternity test is a mitochondrial DNA test. It will be slower, and I can give it to you tomorrow morning."

"That's not in a hurry, people have already secured it." Lin Dong put the dossier on the table, squinted at Qi Ming's smooth to reflective face, and said with a smile: "Didn't sleep well these two nights? I see you The dark circles came out."

A fool would not be able to hear what he said was ironic.Qi Ming heaved a sigh of relief, did not continue, moved the unusually thick file, and flipped through the autopsy report.Looking at it, he raised his face to look at Lin Dong, his brows were slightly frowned, and his eyes flashed with an unbelievable expression: "Mother, strangle your son to death with your own hands?"

It's not that he has never handled the case of Hudu Shizi, he also handled the case of stuffing a newborn child into a locker to starve to death, but he was still deeply shocked when he encountered it again.Although he doesn't like children very much, he still can't resist the bond formed by blood.When helping his younger sister with his niece, he could let the little girl hold her fingers all night without taking them away.

Nodding, Lin Dong left the desk and poured a cup of coffee kept warm on the induction cooker self-sufficiently.Qiming's coffee is all his own, and it's not a little bit better than the cafeteria.Yes, coffee is now provided in the cafeteria. It is said that it is the result of Luo Jianan pestering the logistics veteran Jia for a long time.However, the coffee that old Jaken bought with blood tasted like the ashes washed out of the stove. Qi Ming poured it after only one sip, which meant that Luo Jianan flattered the donkey's hoof.

Seeing that he was pouring the coffee, he had the intention of sticking in here, Qi Ming hurriedly said: "Let's put the file here first, I'll take it back to read at night, I have something to do later."

Before Lin Dong could figure out the reason why the other party issued the expulsion order, he heard Luo Jianan's smoky voice coming from the corridor: "Yes, I will be interrogated again tomorrow, and then I can hand it over... huh? Jiang Bin? What did he do... Dear Well, I'm afraid he can do it, if he is willing to intervene in advance, he will intervene in advance, and let my master connect with him later... Well, then, I will die first, the boss, I have to send Teacher Qi to the hospital."

go to the hospital?Two meters away, Lin Dong's gaze flickered to Qi Ming: "What's wrong with you?"

Qi Ming tensed up: "Check your eyes again."

"Oh……"

Thinking about the fact that Qi Ming hadn't seen Qi Ming get up from his chair for several hours from the time he sent the inspection materials to the present, and hearing the other party's awkward tone, Lin Dong felt as if he had guessed something.
