Chapter 671: Shock: Cryptography Professor Dies, the Truth Behind a Crime

When interrogating the nanny, Qi Changye came over specifically.

But he arrived a little later than expected. By the time he reached the place, the main course of the interrogation had basically ended.

Before Qi Changye could express anything, Tao Lu called Liu Cheng up and asked him to report in person.

Liu Cheng sat upright, hands on his legs, and said: "Through police dogs, we found the aconite discarded by the nanny Li Shuyi in the green belt near Zhou Xiangyang's house. After showing it to her, Li Shuyi confessed everything..."

"What is the motive for the crime?" Tao Lu asked.

Liu Cheng first looked at Tao Lu, then said: "Nanny Li Shuyi is 56 years old this year and has been a nanny for Zhou Xiangrong's family for four years. It was about a year or more after she started working, about a year or two ago, that several nephews and nieces of the Zhou family felt that Li Shuyi worked meticulously, had a good attitude, and was capable, so they hoped she could work for a long time. So they promised Li Shuyi that if she could work in the Zhou family for five years, or send off the old man Zhou Xiangrong, they would solve a job for her son, a temporary worker in a school or public institution in the capital, the kind with social security..."

Liu Cheng paused slightly and said: "Li Shuyi planned it very well, but her daughter-in-law was accidentally pregnant. The two originally didn't plan to have children, but suddenly they had one, and Li Shuyi was very happy. But the daughter-in-law planned to have an abortion, the reason being that no one was there to take care of the confinement, take care of the pregnant woman, and no one was there to help bring up the child. Li Shuyi was very anxious. She wanted to resign to take care of her daughter-in-law, but she was reluctant to give up the promise of the Zhou family. Finally, she came up with such a perfect idea."

Qi Changye listened with his brows locked.

To be honest, nanny murder is no longer a fresh thing for the police. Cases like the Hangzhou nanny case are emerging one after another across the country. There are also nannies who turn into angels of death, specifically killing elderly people to collect "deposit fees."

But Qi Changye always felt it was too smooth. This completely did not conform to the case-handling process he was familiar with, as well as the nature of the cases he came into contact with.

Moreover, from the first half of the case, this case still had considerable concealment and difficulty.

Qi Changye couldn't help but ask: "After the incident, the nanny was at the scene, right? Did you let the nanny go home later? Or did you bring her back?"

"After recording the statement that day, she was allowed to go back." Liu Cheng thought for a while and said: "She was brought back the next day."

Qi Changye looked slightly disappointed. If this nanny had died, or disappeared, that would really be a major case, and it is very likely that they would really have to ask someone for help and search the whole city.

Although it felt very troublesome, isn't this a major case worth paying attention to?

Qi Changye was a little unwilling, and a little worried, and asked again: "Then on this day, did anything strange happen, or any special phone calls, or any other unexpected situations? Traffic accidents?"

"Cough cough..." Liu Cheng could hear what Qi Changye meant, shook his head helplessly, and said: "Team Leader Qi, at present, it is just an ordinary nanny. We also asked, and she didn't encounter any strange situations. As for the nanny's situation, we also have a certain understanding. The nanny's son and daughter-in-law have been married for more than three years and have never planned to have children. The accidental pregnancy is also true..."

Under Qi Changye's gaze, Liu Cheng described in detail the evidence and other materials obtained.

Finally, Liu Cheng emphasized: "Li Shuyi's uncle was a barefoot doctor. She learned from her uncle when she was very young that aconite is highly toxic, and raw aconite is even more toxic, etc. These are all situations that Li Shuyi confessed herself."

"Alright. I know." Qi Changye shrugged, just a little tangled, and more, just unaccustomed to the smooth sailing of this matter, his brows never relaxed.

Liu Cheng didn't care so much. Anyway, he was used to solving cases smoothly now. He looked at Tao Lu with a smile and said: "Branch Chief Tao, if there is nothing else, I will go back. The brothers dug thousands of meters of green belts today, dozens of trash cans, all waiting for me to treat them..."

"Go, go." Tao Lu waved his hand to let him withdraw, and then looked at Qi Changye.

Since the words had reached this point, logically speaking, Qi Changye should also say goodbye. Of course, if he felt there were doubts and wanted to continue the investigation or even take over the case, that was his power, and Tao Lu couldn't control it.

"Team Leader Jiang, I have a question here." Qi Changye turned his gaze to Jiang Yuan who had been silent.

Jiang Yuan's reaction was half a beat slow, and then he smiled with high emotional intelligence and said: "Director Qi, please speak."

"I don't deserve it, I don't deserve it." Qi Changye declined modestly, smiled again, took out an envelope, and said: "I have some photos here, would you like to take a look?"

"Okay." Jiang Yuan received it, took it out and looked at it, and said without surprise: "This is not a photo of this case, right."

The photos in his hand were long-range shots of a storefront, which felt a bit out of place with the Zhou Xiangyang case.

"It is a photo of another case. For the specific case situation, forgive me for selling a pass. Team Leader Jiang, please help take a look. If you can find anything, just say it. It doesn't matter how much, it doesn't matter how deep."

Tao Lu didn't even aim at the stack of photos, just picked up his heavy cadre cup and said: "Jiang Yuan, you just talk about technical things, just say what is relatively certain."

Qi Changye sighed and said: "Branch Chief Tao, it's not that serious."

Tao Lu smiled and didn't say anything.

Jiang Yuan took the photos and looked at them one by one.

Judging from the scene shown in the photos alone, this is a case of a storefront being stolen.

The storefront with a rolling shutter door, after being pried open, the items inside were looted, and the remaining objects were also scattered all over the floor in a mess. Looking closely, it was mainly hardware and building materials.

Jiang Yuan had seen many similar scenes before. Theft cases have their own differences, but the core elements are about the same.

However, this does not mean that theft cases are easy to solve.

Most theft cases are easy to solve, often benefiting from the carelessness of the perpetrator—of course, this can also be understood as a kind of inevitability, because theft is often long-term. If you do too much, it is naturally difficult to maintain rationality, seriousness, meticulousness, and compliance for a long time...

On the contrary, if the perpetrator of a theft case is careful enough, the case is very difficult to solve.

Just on the motive of the crime, theft cases are often very annoying and purely random. The purpose of theft is usually to seek money, which is correct, but the money is not necessarily displayed on the surface. Coupled with the randomness of the thief himself, some people like to look at money, some people like to look at difficulty, and some people may just like certain numbers, or the color of the door, the orientation of the window, etc...

If the theft personnel do not commit a series of cases, purely random theft cases are simply more difficult than getting rid of the Pleasant Goat.

The photos of this case that Qi Changye took out looked difficult. No fingerprints, no footprints, no DNA, and no surveillance video. Even a major case task force with a lot of resources would frown wildly when encountering such a case.

Jiang Yuan also looked at the photos one by one, looked at them again, and looked at them again...

Qi Changye waited until the tea in the cup was dry. Seeing that Tao Lu didn't add water, he coughed twice and said: "Team Leader Jiang, or I will leave the photos here, and you can take your time to look at them later. Of course, if you think it is necessary, you can also go to the scene to take a look, but the scene has been cleaned up, and you can only see the situation on the periphery."

Jiang Yuan, who was looking at the photos, said "Hmm" a bit slowly.

Qi Changye didn't care, smiled and stood up and said: "Then that's it. If there is any situation later, you notify me, we will update the news at any time..."

Jiang Yuan heard this and raised his head, slowly saying: "Speaking of updating the news at any time..." ===== CHAPTER 672 =====
