Tiger Police

Chapter 579 Phosphorus Poisoning

Hu Pingtao felt that the scope of the case was too wide, far beyond previous expectations.

I thought it was just food poisoning, or poisoning.Now it seems that the internal disputes in Cao Zhong's family alone are a headache, not to mention that there are many other things involved.

Of course, it cannot be ruled out that when Pang Zhonghua and Liao Yan introduced the situation, a lot of personal factors were involved.

For example, Liao Yan's sympathy for Liu Xiao'e, the congeniality between Pang Zhonghua and Cao Zhong, and so on.

Hu Pingtao was about to continue asking when his cell phone rang.I took it out and saw that it was Ding Jian's number.

"Where are you?" Ding Jian asked.

"I'm at the wholesale market." Hu Pingtao asked subconsciously, "Have the test results come out?"

"Well, it's out." Ding Jian spoke in a dignified tone.

Hu Pingtao was quite surprised. Ding Jian in his impression likes to joke, sometimes even the dead.

As long as Ding Jian spoke in this tone, it indicated that the situation was serious, or something unexpected went wrong.

Hu Pingtao couldn't help feeling tense, and asked, "What happened?"

Ding Jian said: "I can't say a word or two clearly on the phone, let's talk about it when you get back to the office!"

Hu Pingtao said: "Okay, I'll hurry back now."

……

Half an hour later, the office of the criminal investigation team of the sub-bureau.

As soon as he entered the room, Hu Pingtao saw Ding Jian sitting on the chair, and asked quickly, "What's the matter?"

Ding Jian sat on the chair stretched out, his sitting posture was similar to that of a tortoise basking in the sun with its belly stretched out.He lazily picked up a document on the table and handed it over: "The inspection report is out, you can read it yourself!"

Hu Pingtao quickly took it and opened the folder.

After a while, he browsed through it roughly and shouted in disbelief: "No toxin was detected in all the samples...how is this possible?"

Ding Jian crossed his hands on his belly, his chubby face was full of helplessness: "This is really weird, I can't figure it out no matter how I think about it."

"I took people to investigate the scene. I took all the vomit, rice, flour, oil in barrels, seasonings, vegetables, and even the leftovers in the refrigerator that I didn't eat the night before, as well as dumplings. I took a sample. I thought that there must be... no, at least one of them should contain toxins, and I can find clues as long as I follow the clues. But I never dreamed that the final test result turned out to be zero toxins. "

Hu Pingtao weighed the folder in his hand, and asked uncertainly: "Could it be... Could it be that you missed a certain sample when you were testing?"

Ding Jian curled his lips and said very unhappy: "Hey! You can question my personality, or think that I am lazy, but if you want to blame me on work, then I won't admit it at all. !"

"My old man has been working as a forensic doctor for so many years. Do you think my tricks are for nothing? Besides, when did the test report from me go wrong?"

This is correct. Although Ding Jian seems unreliable, he really has nothing to choose in terms of work.He has been rated as an "Advanced Worker" for several years in a row, and his name often appears on the "Legal News" and industry websites, regardless of the branch bureau, municipal bureau or provincial department.Even Ran Ting praised him several times on different occasions: Ding Jian from the Gudu Sub-bureau is a good comrade... a thousand words will be omitted from now on.

Despite this, Hu Pingtao was still cautious: "Are you sure that all samples have been tested?"

Knowing Hu Pingtao's habits, Ding Jian sighed: "I know what I do. I'm also worried about what might happen! So I did two tests in succession, plus a retest, which is a total of three times."

"Think about it, the two groups of people have been tested three times, and the possibility of missing it is extremely low. If you can still miss a sample... I swear I will never enter the laboratory in the future, and I will never do forensic medicine .”

Ding Jian seldom swears and swears, which means he is sure about something.

Hu Pingtao frowned, walked slowly to his chair and sat down, and said to himself: "All samples are free of toxins... This is strange. The Cao family has five children, why did they get food poisoning Woolen cloth?"

"Wait...it's not..."

Suddenly, a light flashed in Hu Pingtao's mind, and an expression of enlightenment appeared on his face.

Sitting opposite, Ding Jian took everything in his eyes and deliberately teased: "Now you know why I called you back?"

Hu Pingtao nodded clearly, and asked seriously: "This case is not food poisoning, and the cause of the poisoning of the five members of the Cao family is unknown?"

"At present, it can be judged that the poisoning of Cao Zhong's family has nothing to do with food." Ding Jian explained his point of view: "Don't worry about the test, I have searched Cao's family all over, and everything that can be eaten... should be everything that can be eaten." I have tested all the things in the entrance, and found no toxic substances."

As he spoke, Ding Jian raised his finger to the folder Hu Pingtao had on hand: "Look at the third page from the bottom of the document. I called the hospital today and communicated with them. Because they died one after another. The two children, especially the youngest son of the Cao family, are young and have weak resistance. The hospital also did a preliminary blood test, and the results from my side are exactly the same."

Hu Pingtao frowned and asked, "What specific toxin caused it?"

"Phosphate." Ding Jian said: "After being poisoned by this thing, symptoms such as coma, vomiting, and body organ edema will appear one after another, and eventually lead to death."

Hu Pingtao recalled what Cao Zhong said in the hospital, and nodded slightly: "Cao Zhong felt dizzy and nauseated that night. He thought it was something wrong with the dumplings, so he didn't eat too much, and went to bed. Wait until the next day. When I woke up the next day, I found that the whole family was unconscious... This symptom can be matched."

Ding Jian agreed: "The hospital gave Cao Zhong, his wife, and his eldest daughter a comprehensive checkup. All three showed signs of organ edema. Phosphorus poisoning was not diagnosed until this morning."

Hu Pingtao said subconsciously: "If it's phosphide, it's very strange."

Phosphides usually refer to binary compounds composed of metal or nonmetal, such as calcium phosphide, zinc phosphide, aluminum phosphide, sodium phosphide and phosphine.

All phosphides are highly toxic substances.

Ding Jian understood what he meant: "Phosphorus is very pungent, and it is usually used as an insecticide or for cleaning. If it is accidentally mixed with food, as long as it smells that smell, I guess other than idiots and Fool, no one will touch it."

As he spoke, he raised his hand and tapped his head lightly: "The people from the Cao family should be fine here, right?"

Hu Pingtao's eyes narrowed slightly: "We need to change the direction of the investigation. It seems that someone deliberately poisoned."

Ding Jian shrugged his shoulders: "This is your business. I guess Cao Zhong usually offends a lot of people. If he wants to kill his whole family, he needs a lot of phosphide."

Hu Pingtao was puzzled: "Phosphide is a controlled product. Except for chemical units, it is impossible for ordinary people to get such a large dose!"

Ding Jian continued: "I looked around the scene of the crime, but I didn't find any suspected crime tools. This is unreasonable! Phosphide volatilizes quickly, and once it is put on for too long, it is useless."

Hu Pingtao nodded and said: "There is also a problem with time. Think about it, Liu Xiao'e took the three children and cooked the dumplings and ate them first. When Cao Zhong came back, the three children were already full. His son yelled no Comfortable, go to bed first. Liu Xiaoe asked her two daughters to wash their faces and feet, and Cao Zhong was sitting at the table eating dumplings alone at this time... There is an obvious time difference."

Ding Jian asked suspiciously: "Do you suspect that Cao Zhong is a criminal suspect?"

Hu Pingtao said seriously: "Cao Zhong is indeed suspected, but I'm not sure he did it."

Ding Jian asked: "What should I do next?"

Hu Pingtao thought for a while and asked, "Do you have anything else on hand?"

"Not yet." Ding Jian replied.

"In that case, you go to the hospital with me." Hu Pingtao explained: "Because Cao Zhong and Liu Xiao'e are not in the same ward, they are separated, and I have to ask them about some things."

……

Hospital, intensive care unit.

Liu Xiaoe was lying on the hospital bed. Although she was awake, her face was pale and she looked extremely weak.

Hu Pingtao looked at the glucose needle water hanging in front of the bed, probably the nurse had just hung it up before he came in, and the liquid level only went down a very shallow layer.

He pulled a chair from the side, sat down in front of the bed, and watched Liu Xiao'e carefully.

Her facial features are indeed terrible, and there is a sense of disobedience that cannot be explained in words.

Liu Xiaoe stretched out her right hand from under the quilt to cover her face.

Seeing this, Hu Pingtao asked puzzledly, "What's wrong with you?"

Liu Xiaoe turned her face in the direction opposite to Hu Pingtao's gaze, and her voice was very low: "I... am not good-looking."

Hearing this, Hu Pingtao smiled gently, and comforted him: "You think too much. I'm a policeman, and I came here today to ask you to understand the situation."

These words obviously touched Liu Xiaoe, she slowly slid her hand covering her face, turned her body halfway, and asked suspiciously: "Have you...have checked it?"

Hu Pingtao explained: "We are looking for clues. If you can help, we can solve the case as soon as possible."

Liu Xiao'e said: "What's there to investigate? It's obvious that it was Cao Zhong's poison. He always hoped that our three mothers would die soon, so that he could take his son and find another good one."

When she said this, she didn't have any emotional fluctuations on her face, and her tone was very flat, as if this matter had nothing to do with her.

Hu Pingtao turned his head and glanced at Ding Jian who was sitting beside him, who was opening a folder and taking notes.Hu Pingtao turned his gaze back to Liu Xiaoe and asked, "Why do you think it was your husband who poisoned you? Also, how did he poison him?"

Liu Xiaoe found it difficult to speak while lying down. She supported the bed with her hands and tried to sit up.Seeing this, Hu Pingtao quickly stood up, supported her arm, placed the needle vertically on her waist, then walked to the end of the bed, shook the pole, and pushed the front half of the bed up.

"Thank you!" Liu Xiaoe felt much better when she sat up, and her chest was not as stuffy as before.She half-covered her mouth and nose with her left hand, and said earnestly, "Cao Zhong and I would have been unable to live on long ago. If it wasn't for the child...I..."

She shook her head feebly, she didn't say the following words, but the meaning she wanted to express was clear enough.

Hu Pingtao stared at Liu Xiaoe, he found that the woman raised her hands to cover her face was very natural and smooth, obviously she was used to doing this.

When he was at the police station, Hu Pingtao knew an old woman who lived nearby.The man suffered from facial paralysis when he was in his 40s, and half of his mouth was crooked.Since then, she has habitually turned her head to one side, and turned her face sideways when speaking, in this way to cover up her physical defects.

After a long time, Hu Pingtao asked seriously: "Just because Cao Zhong beat you, do you think he poisoned you?"

Liu Xiao'e didn't answer directly, her voice was full of suppressed anger: "Except for him, who else would do such a cruel thing to me and my daughter?"

Hu Pingtao noticed the word "daughter" in Liu Xiaoe's words, not "children".

He decided to add more weight to the talking scale.

"This case is more serious than you think. Both your son and youngest daughter are dead. Two lives!"

Liu Xiao'e had known the news of her son's death before, and the news of her youngest daughter Cao Pandi's death after rescue failed was also known later.She had already cried at that time, and now that Hu Pingtao mentioned it again, she couldn't help but shed tears, grabbed the quilt with her right hand, tightly covered her lips, and sobbed silently.

Hu Pingtao did not directly point out the key issue of "phosphorus poisoning".

He observed Liu Xiao'e's emotional changes, and said calmly: "I came from the wholesale market. I was doing case investigations there before, and I talked to your neighbors by the way. Pang Zhonghua and Liao Yan live here. It's across from your house. Liao Yan is very enthusiastic and told me a lot about you."

Liu Xiaoe's body visibly trembled, and the gap between her left hand covering her mouth and nose and her face was wider than before.

"Liao Yan... what did she say about me?" Although it was an inquiring tone, it could be heard that the tone was a little impatient.

Hu Pingtao still smiled: "A lot. Anyway, Liao Yan told me all the things you said to her."

After a pause, Hu Pingtao explained: "Whether it is good or bad, as long as we ask, Liao Yan must answer truthfully. As I said just now, this is not an ordinary case, but a murder case. Citizens have to cooperate with the public security organs. Obligation to investigate. If Liao Yan does not report the case, or conceals the facts of the case, she will also be held accountable."

After saying this, Hu Pingtao gave Liu Xiaoe a few seconds to think and react.

This woman is very shrewd, yet she also has great fears and burdens deep inside her.

Guessing that the time was almost up, Hu Pingtao asked in a more serious tone, "Why do you think it was Cao Zhong who poisoned you?"

Liu Xiaoe remained silent.

After a full half a minute, she raised her head, looked past Hu Pingtao, looked at the open door behind him, and begged, "That... can you close the door?"

Hu Pingtao and Ding Jian subconsciously turned their heads and looked at the door behind them.

Ding Jian stood up, walked over, and closed the door.
