We contacted the Eastern District Bureau and said that there were thirty-four pieces left in the stack of coins that were opened at that time, in other words, Jiang Tiannan used at least 6,600 yuan. Xu Rui was responsible for contacting the credit union to check the deceased's latest withdrawal record, and after finishing the account number, he returned the news not long after, saying that Jiang Tiannan's last withdrawal was on the 7th of January this year, and he withdrew 500 yuan.

A total of seven thousand and one hundred dollars.

According to the calculation of a lone old man and thirteen dogs, 7,100 yuan is almost enough for more than half a year, that is, the time of death two months ago, if you are frugal, you may not be able to spend it all.

Next, I drove with the living dead and Ah Li to Xiaoshui Alley on Hongnan Street, and when we arrived, it was already half past three in the afternoon. Jiang Tiannan's yard was still sealed and cordoned off by the police at the time of the crime.

The bloodstains in the yard have long since disappeared, of course, not by man-made, but by rain.

I opened the seal and entered the courtyard, took the key to open Jiang Tiannan's door, the wine jar was still in the kitchen, I lifted the lid, and the mellow smell of wine came in. I have to say that Jiang Tiannan's wine-making skills are not false, even I, who don't drink, are ready to move, if it weren't for the death of people in this wine vat, I'm afraid that the living dead would have been unable to help scooping up a cup.

I spent half an hour with the living dead and Ali reading carefully, and we didn't find any vague clues, and the murderer was too clean and neat after the invasion.

Ah Li looked around at the layout of the Jiang family's house, and then I called Lao Song, who lived not far away, and he said that at home, I asked Lao Song to go to Jiang Tiannan's house immediately.

After a while, Lao Song came cooperatively, but he was afraid to enter the door.

We had to go out of the courtyard to talk about Jiang Tiannan.

Lao Song was puzzled and said, "What is the matter with the police officers calling me?" ”

"At that time, you were the first to see Jiang Tiannan's family have an accident, right?" I asked.

Old Song nodded again and again, and he said with deep fear: "I haven't forgotten this terrifying scene until now, I still remember it vividly, the death word of thirteen dogs is based on the blood on the ground...... The day after that, I had a serious illness and was really scared silly. ”

"Let's think back to whether I saw anything inconspicuous at that time." I said.

Lao Song closed his eyes and thought about it, his body suddenly trembled and said, "No, when I think about it, that scene appears in front of me." ”

"Hmm......" I looked sideways at Ah Li and said, "Ah Li, it's your turn." ”

Ah Li thought for a moment, took out a pen and paper and asked, "How is Jiang Tiannan's usual life?" Where are the places where the money is spent? ”

"This old Jiang is usually quite frugal." Lao Song said while recalling: "I go to the vegetable market every day to buy vegetables for more than ten yuan, a bag of rice and a bag of noodles a month, he doesn't eat much, most of them are eaten by the Thirteenth Taibao, the earth dog is not particular, unlike pet dogs that eat dog food, but Lao Jiang will still dress up a bag of dog food every other week, and the bag is quite big." ”

"Big bag of dog food...... Ah Li nodded, and then he asked, "Do you know how much a pack is?" ”

Lao Song thought for a while, and he said with certainty: "Fifty yuan seems to be." ”

After remembering it, Ah Li asked, "How often does Jiang Tiannan buy clothes?" ”

"Two or three years." Lao Song said: "Old guys like us, we basically don't change our clothes much. ”

"He doesn't have anything else to spend his money on?"

"No, it's just the water and electricity bills and phone bills......" Lao Song said, his eyes lit up and said: "By the way, in May and June this year, the seventh child of the Thirteenth Taibao was sick, and Lao Jiang took it to the pet hospital and spent two thousand yuan to cure it." ”

"That's good." Ah Li immediately took the note and said, "Is there anything else?" Does Jiang Tiannan smoke? Drinking? ”

"No, don't smoke, gamble, don't prostitute, drink half a bowl of self-brewed rice wine every day, hehe." Lao Song said with a smile: "Lao Jiang's physical condition is good, and after so many years of neighborhood, I have hardly seen him sick." Alas...... I can't imagine who I provoked so suddenly! ”

Ah Li thought for a moment and said, "Oh yes, when was the rice wine in Jiang Tiannan's wine jar made?" ”

"Last fall." Lao Song said uncertainly: "Anyway, it's not this year." ”

I thought for a moment, it should be right, otherwise there wouldn't be so much less wine in the vat, although I had to drink it with it, but the amount wouldn't be too large.

Ah Li put the pen and paper away and said, "I'm done." ”

"Old Song, you go home first, if there is a need for you, we will contact you again." I shook Lao Song's hand, and the other party nodded and turned to go home.

I smiled and asked, "Ah Li, how is it, do you have confidence?" ”

"I can almost figure it out." After speaking, Ah Li added: "But I still have to give details of the water and electricity bills and phone bills that Jiang Tiannan paid from January to before he died." ”

"Don't worry, the boss has already checked it, I'll ask him." I picked up my phone and sent a message to Xu Rui, and soon after, he replied: "The three items add together for a total of 560.9 yuan, as for the detailed list from January, I have printed it, you go back to the police station to see it." ”

“560.9。” Ah Li Nian chattered, he blurted out: "Jiang Tiannan spent about 6,900 yuan from January to two months ago, if I guessed correctly, Jiang Tiannan's house at that time had about 200 yuan in loose cash, not outside the drawer, or in his pocket, or in his wallet. ”

My eyelids jumped and I said, "Wait a minute." "Then I called Xu Rui and asked him to see the details of the search at the scene of the crime, how much cash was in the house except for the drawers, which we jumped over to see at the time because there were no clues.

Less than five minutes later, Xu Rui called and said, "There are 131 yuan in the wallet, and the pants pocket I wore when I died was 60 yuan and 7 cents." ”

"Okay." I hung up the phone and quickly calculated, adding up to nearly one hundred and ninety-two yuan, indeed, as Ah Li speculated, the scattered cash was only about two hundred, thinking that he had estimated the approximate value of the three expenses almost in the blink of an eye after listening to the three fees before, I couldn't help but give a thumbs up and said: "Tough!" ”

The living dead also said with admiration: "He is worthy of being a computer master, and his brain is faster than that of a computer." ”

Ah Li smiled awkwardly and said, "The seniors are smiling." ”

We walked around Jiang Tiannan's house again, and found nothing else, so we locked the door of Jiang's house, restored the seal, and drove back to the police station.

After arriving, we came directly to the office, Ah Li read the detailed list of the three expenses, paid a total of 97 yuan in January, and then contacted Jiang Tiannan's daily consumption, he took the pen and estimated it for two minutes, and said: "Jiang Tiannan's 500 yuan can be spent about February 13, and the error fluctuates for about three days." In other words, the delivery time should be from January 7 to February 16. ”

"Is it the range of nearly forty days...... Xu Rui said thoughtfully: "I thought about it wrong before, and I forgot to count the unspent time of five hundred yuan, but it doesn't matter." When the money giver comes, he will avoid people's eyes and choose after dark, and Jiang Tiannan's identity is not simple, if he is sleeping, it is impossible for the other party to come to disturb. Xiaochen, you now go to the Tianyan Department, transfer five monitors, and ask them to check the surveillance images around Xiaoshui Lane on Hongnan Street between half past six and half past twelve every night in the past forty days, the target may be driving, and he may be carrying a bag in his hand when he enters the alley, and it has only appeared once in the past forty days. I want to see who sent the money to Jiang Tiannan. ”

Not long after, I came to the office of the Tianyan department, and repeated the time, place and requirements that Xu Rui said, and the monitors had a headache, but the total time range was 240 hours, and on average, everyone was only 48 hours, and they were relieved when they thought of it, and immediately started to get busy, saying that the results would come out at this time tomorrow.

I stayed here for five minutes and then returned to the office, where Du Xiaoworm and Ye Jia also came, and they were looking at the details of Jiang Tiannan's case.

Du Xiaoworm's eyes suddenly moved, and she said solemnly: "Like Jiang Tiannan's death and the scene of pets posing words, if I remember correctly, there was a similar case before, and I inadvertently glanced at it when I was still flipping through the file......"
