In the face of Jiang Jianzhou, Chu Yu did not elaborate on the contents of the investigation, but went straight to the point and asked the other party to cooperate unknowingly: "Have you received fraudulent calls or text messages recently?"
Jiang Jianzhou recalled: "No, I usually see a lot of police propaganda, and they teach how to distinguish scams. I have learned a lot, and I can see it when I really encounter it."
Chu Yu nodded, "Have you received a text message from any business? For example, a certain promotional event, followed by a link for you to fill in your personal information or other content?"
"It seems there is. It's from a supermarket. Let me fill out a questionnaire."
Chu Yu smiled and said, "Can we check your phone?"
Jiang Jianzhou took out his mobile phone. It was a smart phone. He deliberately dug out the text message, hesitated for a while, and didn't immediately give them: "Do you just need to check the text message?"
Muyu is not as approachable as Chu Yu, let alone a professional smirk, not even a professional tone: "Don't worry, it won't involve privacy, just check whether your memory device is safe."
"How to check? Do I need to pull out the card?"
Muyu took the phone directly and lowered his head to fiddle, "How many years have you used this phone?"
"It's been almost three years, and it was given by my son for his birthday."
"What are they used for?"
"I just play music occasionally and listen to the news. I don't use it very much. It's mainly the same as the old mobile phone, calling and texting with my family."
The old man sat next to Muyu and wanted to stare at her to check. Chu Yu continued to ask questions, diverting his attention: "Has anyone come to sell it recently?"
"No, they generally can't enter the unit building."
Chu Yu nodded, "Okay, please take out your bank card, we need to check."
"Bank card?" Jiang Jianzhou was a little puzzled, "What exactly do you want to check?"
"See if you have lost your bank card."
Jiang Jianzhou hesitated for a moment, but went into the bedroom. While he was away, Chu Yu glanced around the room. The interior was very delicately decorated. It could be seen that the family was well-off. The dining table was made of marble. There are snacks on the TV cabinet and balcony, and there is an armchair by the window for viewing the scenery.
After rummaging inside for a while, the old man took out the cards. There were five cards in total, belonging to different banks, including commemorative cards. Chu Yu took it, mainly to make sure that his family had the same card as Xia Yihan.
"Are all your cards here?"
Jiang Jianzhou was a little dazed, and after a while, he replied, "Yes, it's all here."
The cards were placed in a row, even more so to show off their wealth. Each card is "rich with money".
Chu Yu took out the information given by the bank, compared it with a gesture, and asked, "Have you ever lost your bank card?"
The old man frowned and denied it immediately, but quickly nodded again: "Oh, yes, yes, there is one, it seems to be from ICBC, it was lost not long ago, but I found it again later."
Chu Yu, "If you encounter loss in the future, it is best to report the loss. If it falls outside and is picked up by others, it may transfer all the money in your card."
The old man agreed, and after a while, his expression became nervous: "Officer, shouldn't all the money in my card be wiped out?"
"No, now it's mainly prevention. We received a report yesterday that there are suspected criminals in this block, targeting the elderly living alone. They disguised themselves as salesmen, tricked the elderly into scanning codes, stealing personal information, swiping away personal savings, and returning Some people who promote health care products need to pay by bank card, but the card information will be copied. At present, we are still collecting information and statistical data.”
It happened that a similar case had just happened in this block, and Chu Yu applied it to "selling dog meat on sheepskins".
Jiang Jianzhou: "Oh, I haven't encountered any of these, but I have heard of them recently, and it seems that there are quite a few old people who have been deceived."
After Muyu checked, he returned the phone to him.
Chu Yu: "Yes, but it's fine if you haven't encountered it, but if you find suspicious people in the future, please be sure to contact us."
Jiang Jianzhou took the phone and nodded with a smile. He looked approachable, but Chu Yu could feel it, and he was still a little nervous.
The question was almost over. The two of them got up and left. Jiang Jianzhou sent it to the door with a smile: "The two police officers have worked hard. In this winter, go door to door to understand the situation."
Chu Yu also politely said: "Thank you for your cooperation, you are at home alone, usually pay more attention to safety!"
After the other party closed the door, Chu Yu and Mu Yu looked at each other and didn't speak. They quickly left the unit building and met Song Qingyang at the door. The three walked out of the community.
Song Qingyang cared about the two of them: "How is it, have you run into a strange grandpa?"
The wind was a bit strong, Chu Yu buried his head slightly, his chin nestled in the collar of the sweater, "Fortunately, people look quite normal."
It was inconvenient to talk about the case outside, so the three of them held back all the way, and finally returned to Superman.
Fang Datuo was busy on the fifth floor, and when he saw the movement on the second floor, he rushed down. He wanted to see their faces and guess the result, but found that it didn't work at all - Muyu has always been expressionless, Chu Yuxi is not happy, Song Qing Yang was heartless and felt that the three of them were like going out for a spin and came back for dinner.
"Sisters, have you found anything?"
Muyu glanced at him: "Some sisters, Grandpa Jiang has a Trojan program in his phone, and there are not a few APPs, the memory is basically full, and the text messages and call records of the past three years are all there, but they have not been deleted, and there is a suspicious link. The time was March this year, and I found the verification code to apply for the payment account, which was opened in April this year."
Chu Yu's fingertips were a little cold, and he sighed: "His bank card has not been lost, all the cards are there, and he doesn't seem to know that his card has been copied."
Song Qingyang: "Hey, doesn't this basically rule out suspicion? He is an empty-nest old man who was brutally poisoned by Overlord Flower."
"Not necessarily. Although I didn't find any suspicious points in the economic information, I noticed other suspicious points. Xiaoyu, did you just notice that there are snacks in the old man's house, such as candy, plum, dried fruit, etc., sugar content It's quite tall, aren't elderly people generally taboo?"
"It's usually like this, but it's not necessarily. My grandma likes to eat sweet and soft food, otherwise she will have no taste in her mouth."
Chu Yu: "And I was sitting on the sofa, and I could see the second bedroom. The bed was covered with sheets and the window was open. It looked like someone was living there."
Fang Datuo: "Could it be that the children go home and sleep occasionally?"
Chu Yu was noncommittal, his face was calm: "Anyway, the whole house gives me the feeling that there is still a young man living in it, either hiding or not at home.
Muyu: "I checked his household registration information before, there are only four members of his family, except for the deceased wife and the children who moved out, he is only an old man, and it may be other relatives and friends who come to stay for a few days... But before you leave, tell him that you should pay more attention when you live alone, and he didn't say that you are not alone."
"Well, you can sort out his information again. I'll call the community property and ask about the specific situation of his family."
Chu Yu dialed the property number of the □□ community and asked about the situation of the 10-1 households in the 10th building. The property management knew that it was the police who came to investigate not long ago, and reflected: "There are people in the community who pay special attention to the elderly living alone and will provide community services. Mr. Jiang has always lived alone, but his body is still strong, so he did not accept the help of social workers."
After that, Chu Yu called Jiang Jianzhou's children again. As a community volunteer, he explained that the old man did not receive regular visits. He wanted to check the old man's physical condition to see if he needed help.
Jiang Jianzhou's son is named Jiang Yu, and his daughter is named Jiang Zhu. They are both successful business people. They are busy with business, and now they live in other cities. He is healthy and has no serious illness. Although he lives alone, he can live a good life. Since he has not accepted visits, he does not need them to worry about it for the time being.
After hanging up the phone, Chu Yu rubbed his forehead. He talked too much today, his teeth were dry, and he had to change his identities at any time. For a while, he was a director, a policeman, and a volunteer again, for fear that he would say it. Disconnected.
"Qingyang, please go and install a camera in the corridor today, facing Jiang Jianzhou's door. I still don't believe that the person in his family can never go out."
Song Qingyang got the order, rubbed his hands excitedly, and went to work.
After sorting out the information, Muyu didn't bother to print it, so she took the laptop over. Seeing that Chu Yu's head was big, she didn't bother her old man to see it in person. She directly introduced her voice: "Jiang Jianzhou's family conditions are really good, he's always been from the city, After going through a turbulent era, in his early twenties, he held an important position in a state-owned enterprise. After resuming the college entrance examination, he also obtained a diploma. He was born and educated among his peers. , but he still did a lot of practical things in his position, and the position was not easy. When he was young, he often needed to travel on business. He had been to Liangshui and Honggang, all of which were relatively small prefecture-level cities. Months..."
"Cool water..." Chu Yu repeated the name of the place, "is it near Chenyang?"
"In a province, it is quite far from Wangjiang anyway."
Chu Yu was pacing back and forth in the office, but suddenly stopped and put his hands on the desk: "I remember we used to check Zhou Lanxin's ancestral home, is it also cold water?"
Muyu thought about it: "Yes, she is not a native of Wangjiang. It seems that her family is too poor, so she came to Wangjiang to work and settled here."
Chu Yu murmured to himself: "Is this a coincidence... .. by the way, you can confirm that Mu Shangqing's address before his death was also on North Linquan Road. I felt this neighborhood was familiar from the beginning."
Muyu re-checked Mu Shangqing's information, and soon got a reply: "You remember right, Chief Mu and Huang Nan have been living in the famous residential area on North Linquan Road, and we passed by today, just opposite the residential area. ."
Chu Yu sat down, glanced at Muyu and Fang Datuo, his face paled: "I said earlier that Xiao Huaihua has no relatives, but we may have missed someone."
