"Also, the gastrointestinal contents have been extracted, except for a small amount of thallium sulfate that can still be detected in the feces in the colon, the toxic component has not been detected in the remaining contents, and last night's supper and this morning's breakfast can basically be ruled out, it should be that the hot pot they ate yesterday evening was poisonous."

Speaking of this, Yan Zhongxin paused and said, "As of now, the conclusion of the autopsy is almost that, is there any problem?" ”

Su Ping shook his head slightly, looked at Brother Song, and said, "If there is a problem with the hot pot eaten at Su Haohu's house, then the focus of this case is to determine the source of the poison, so as to further confirm that it is an accidental case or someone deliberately poisoned it."

Song, you and Xiao Qi go outside the toxicology laboratory and wait for a while, the test results should come out soon, and when we confirm which sample has a problem, we will immediately start a corresponding visit. Go ahead, the decision is up to you, and then you and Xiao Qi will act independently. ”

"Understood." Brother Song nodded in understanding, and then left the dissection laboratory with Qi Yuan.

As soon as they arrived at the door of the toxicology laboratory, the results of the analysis came out - the edible salt in Su Haohu's house contained a high concentration of thallium sulfate, so the hot pot soup and dipping water they ate also contained a relatively high concentration of thallium sulfate.

The salt is stored in the seasoning box, unless Su Haohu himself poured the wrong salt, otherwise, it can be considered that someone replaced the salt in Su Haohu's house.

Five of the dipping water had a higher salt content, corresponding to five deceased.

"Is there a problem with salt," Chai Ningning said after learning the result: "If it is a problem with salt, the possibility of an accident is relatively small, no one would be stupid enough to pour thallium sulfate into the seasoning box as table salt, and no dealer has the courage to sell thallium sulfate as edible salt."

What's more, in terms of price, thallium sulfate can be much more expensive than table salt. ”

"So what Team Su said is right," Brother Song took over: "The top priority is to confirm the source of this thallium sulfate, as long as it is confirmed, the case will basically be solved." Sister Chai, how do you say it, is there a discovery on the spice box? ”

"There are several sets of fingerprints detected," Chai Ningning said: "Most of them are Su Haohu's, but there are two groups that do not match Su Haohu's fingerprints, but unfortunately after many fingerprint coverage and oil pollution, the fingerprints are somewhat incomplete, and they have been extracted and fixed, but it is difficult to say whether they can come in handy." ”

At this point, she paused, and then continued: "But judging from the concentration of thallium sulfate in the table salt, combined with the analysis of the salt content of the dipping water he used, he should eat quite heavy salt, and the thallium sulfate he ingested in one meal may reach a lethal amount."

Looking at the traces of the kitchen, his cooking frequency is still relatively high, but he died of poison after eating hot pot at this dinner, and it can be basically inferred that the salt was replaced with thallium sulfate, which is a recent thing.

Therefore, the owner of the fingerprints that have been covered many times and mutilated on the spice box may not be the murderer. Because if it was the poison he replaced, Su Haohu would have died of poison a long time ago, and no matter how bad it was, he would have been hospitalized due to acute poisoning. ”

"Is it poison released recently," Qi Yuan couldn't help but say, "That is, before they ate hot pot yesterday evening, after Su Haohu cooked last time?" ”

"Yes," Chai Ningning nodded in agreement: "But no fresh fingerprints were found on the spice box, and the perpetrator may have been wearing gloves when poisoning."

But this is not a big problem, Su Haohu lives in a relatively high-end community, there are surveillance in the corridors, when I entered the scene, I noticed that there were two cameras just facing the door of his house, as long as you go through the surveillance video, it is not difficult to screen out the suspect. ”

"Then I'll go to the detective and ask later." Brother Song said, and then asked: "Speaking of Sister Chai, can you analyze when was the last time Su Haohu cooked?" ”

"You're a bit of a strongman, aren't you?" Chai Ningning raised his eyebrows, and then said, "But...... You can try, but it will take time, and I won't be able to give you results in the short term. ”

"Okay," Brother Song bowed: "Then let's go to the map detective to ask the result first." ”

"Go ahead."

……

Graphic Investigation Department, after Liu Xun listened to Brother Song's words, he quickly passed through the monitoring in the form of the highest multiple reversal, Brother Song didn't wait, let Qi Yuan wait here for the result, and then ran back to the office, notified Su Haohu's parents to come to the detachment, and told them the news of Su Haohu's death, thought about it, and called Su Haohu's ex-wife again.

About half an hour later, Qi Yuan came to the detachment and said, "Brother Song, I found out, Su Haohu and their dinner party forty-eight hours ago, a total of six people went to his house.

Three of them are delivery people, one is Su Haohu's ex-wife, and the other two don't know each other, but one of them is a little similar to Su Haohu, and may be brothers. ”

"Oh?" Brother Song asked, "Are all the screenshots kept?" ”

"Yes." Qi Yuan bowed: "And their community uses high-definition monitoring, which is very clear, and after looking for a few frames, I found a screenshot of the front face, and I don't need the technical team to do sharpening processing." ”

"That's good." Brother Song said: "Send the photos to Fang Chang and the others, and find a way to confirm the identities of these two people." In addition, let's not leave yet, Su Haohu's ex-wife will come to the detachment later, as for his parents, they are far away, and they will not be able to arrive in the evening at the earliest. ”

"Okay."

……

Twenty minutes later, Su Haohu's ex-wife, Xiong Yunqi, came to the detachment.

Looking at it, she was a little depressed, and after seeing Brother Song, she sighed for a long time and asked, "Can I see Ah Hu's corpse?" ”

"I'm sorry, Su Haohu's body is currently undergoing an autopsy, which is inconvenient." Brother Song shook his head, and then asked, "I take the liberty of asking, how long have you been divorced from him?" ”

"It's been five or six years." Xiong Yunqi turned his head and said softly: "It was a fake divorce at the beginning, in order to buy a house, where did you think that he would cheat...... can't say cheating, the marriage is divorced, it can only be said that he faked it and found another woman.

I couldn't stand it and had a falling out with him. After that, there were a lot of things, after all, I didn't think about the divorce so much at that time, and I went directly to get the divorce certificate. As a result, the ownership of property, the custody of the daughter, and nothing was mentioned.

I don't want to fight with him for anything, the property belongs to whoever is in his name, I have suffered a lot of losses, but I don't care, but my daughter must not give it to him.

In the end, I won the lawsuit, and the custody of my daughter was awarded to me, and from then on, he and I went our separate ways, without affecting each other, and that's it. ”

Speaking of this, she chuckled: "Now that I think about it, it's really stupid, the fake divorce is even divorced...... Forget it, it's all in the past, I can only say that it's all fate. He did ask me to remarry, but I really didn't trust him anymore.

What's the point of holding on without trusting feelings? Reunion of husband and wife after an enforced separation or rupture? Even if they are glued, aren't the cracks still there? ”
