There were also dripping drinks on the edge and around the wine vat at that time, which confirmed that the deceased had indeed struggled at that time, because the wine vat was not full before, and about half of it looked like it, even if Jiang Tiannan put the wine in, it did not cross the edge of the vat wall.

Jiang Tiannan's time of death was the night before.

Through the visit, the police learned that Jiang Tiannan's house was not invaded at that time and the wild dog barked when slaughtered, which was very strange, so the forensic doctor selected a few dogs for autopsy and found that their stomachs had undigested meat, and the meat was checked out of the ingredients of rat poison, which was the banned "tetramethylenedisulfoxidetetramine", and the police found a packaging bag outside the yard, which said "no rat life", which is strong with rat poison, and the packaging is different.

Based on this, the police deduced that the murderer had a better understanding of the situation of Jiang Tiannan's house, and prepared the meat dressed in rat poison in advance and threw it to the "Thirteen Taibao", and they died one after another after eating, so they sneaked into the yard, jumped out of the window and entered the house and drowned Jiang Tiannan in the wine tank, and then dragged the thirteen dogs who died to the cement floor in the middle of the yard, and mended the knives and put them as the word "death", so that the scene of the crime had a strong visual impact.

However, Jiang Tiannan's house has no signs of being turned over, there are more than 30,000 cash in the drawer at home, Jiang Tiannan's passbook has 2 million hundreds of thousands, and his wrist has a string of valuable beads, after testing, this is Hetian sheep fat jade, the texture is delicate, glossy, white, and skin color are all superior things, this thing is tens of thousands of yuan a gram!

The murderer was indifferent, if he didn't know the goods, forget it, but the cash at home was not touched, so he came to kill people, not because of money, but because of Jiang Tiannan himself.

This can make the police embarrassed, Jiang Tiannan is a lonely and widowed old man, how can he have any enemies?

The police checked Jiang Tiannan's ID card and went to Gaoshi where his household registration was located, and no one in the local area had an impression of Jiang Tiannan, in other words, it was just that the household registration was here, and the house had already been demolished.

Therefore, everything before Jiang Tiannan moved to the alley of Qingshi became a fog.

Anyone thinks that it is not easy before the deceased is fifty years old, after all, there are so many cash and deposits, plus a hand of beads, this is not something that ordinary people can have, and he has been raising dogs and playing chess every day for more than 20 years, and he has not done anything else, but he can't find anything, what can he do?

The police checked the road surveillance and found no trace of the murderer, so it seems that the other party is quite cautious.

Jiang Tiannan's death was like a stone smashed into the calm lake of Hongnan Street, especially the terrible and tragic situation of the "Thirteen Taibao" in the courtyard, more and more people talked about it, and the scope of spread became larger and larger, and many people panicked. Two months ago, the media coverage lasted for two days, but then the official blocked the news about the case, so the matter became a topic of conversation among citizens after dinner, and there were no follow-up rumors, and the impact gradually disappeared.

There were no bloody footprints left by the murderer in the courtyard of the Jiang family at the scene of the crime, because the other party deliberately smeared it with dog blood before leaving, and it should have been changed into spare clean shoes to escape from the scene.

Jiang Tiannan's impression in the eyes of his neighbors is that he has a smiling face all the year round, and he has no power to restrain the chicken, and any woman can overturn him, so the police know almost nothing about the murderer, including gender.

But there's something suspicious.

Two of the 30,000 yuan in cash in Jiang Tiannan's home have not been opened, so it is inferred that the money was withdrawn at the bank at one time, but the police contacted the credit union and found that Jiang Tiannan only had that passbook in his name, but he himself had no record of large deposits and withdrawals, and the maximum was only 500 yuan at a time, in other words, the cash was not taken by Jiang Tiannan himself.

And put the cash thing away, how did the 2 million and hundreds of thousands on the passbook come from?

Finally, the credit union found out the source of this money, and almost every year, someone sent money to Jiang Tiannan's passbook in different places, sometimes tens of thousands, sometimes hundreds of thousands, sometimes more than 200,000, and the accumulation reached a huge level over a long time.

At first, the remittance was not a real-name system, but since the year of the implementation of the real-name system, the records displayed have all the same name and identity number, Chu Shengran, whose household registration is located in Baise City, Guangzhou Province.

The Qingshi police contacted the Baise police, and what is surprising is that although there is Chu Shengran, his family is extremely poor, almost having a meal and worrying about the next meal, and the family is even stretched to take out a thousand yuan, how can it be possible to contact Jiang Tiannan for so many years to accumulate and remit 2 million hundreds of thousands? Chu Shengran himself was confused, and the local police found that the other party's situation was true through investigation, and analyzed that someone may have fraudulently used Chu Shengran's identity information to remit money for Jiang Tiannan.

The police retrieved the latest surveillance record of the corresponding time at the place of remittance, this is the beginning of this year, and the man in the surveillance is indeed very similar to Chu Shengran, but his appearance is still a little different, and his walking posture is also different, and he is indeed impersonated.

The living dead beside me leaned his head together, and he said in surprise, "Who is this old man?" It's too inconspicuous......"

"What about the devil......" Xu Rui twisted his stiff neck and asked, "Xiaochen, what do you think?" ”

I shook my head and said, "I feel that the difficulty is greater than the previous case, so I don't have a clue for the time being." ”

The next moment, Xu Rui pretended to be mysterious and said: "The small one is small after all, and I have to be a veteran at the critical moment." ”

"Boss, do you have an idea?" My mind moved, and I said, "Tell me about it." ”

"Cash."

Xu Rui said analytically: "Jiang Tiannan himself has no record of large deposits and withdrawals, where did this money come from?" It was clear that someone sent it to the door, so it couldn't be the one he brought with him when he moved here more than 20 years ago, right? This is a new version of RMB, unless he crosses over. ”

And then...... "I was extremely puzzled.

"The person who sends the money may avoid people and choose to come to the door at night, but they may not deliberately avoid surveillance." Xu Rui said slowly: "Let's let the monitor check the eyes of the sky at both ends of Xiaoshui Alley and the front and back streets." ”

"Well, this range is a bit big, no one knows when the money will be sent, so you can't go forward day after day from the day of the crime, right? The monitors must not be tired and vomit blood? I spread my hands and said unrealistically, "By the time I find it, it will probably be several years." ”

Xu Rui rolled his eyes and said, "Am I that boring?" Calculate and you can get the approximate time frame for sending money. ”

"How?" The living dead asked curiously.

Xu Rui explained thoughtfully: "Count how many pieces of money there are in the stack of coins that are opened, and subtract it with 10,000 to get how much Jiang Tiannan used, this is the first part." ”

I wondered, "Boss, what if the money is sent not just three stacks, but four, five, or six stacks, and the rest is spent?" ”

"It's up to the second part." Xu Rui said with a smile: "Just imagine, if you have cash at home, will you still go to withdraw the money in the passbook?" We found out when Jiang Tiannan last withdrew money. Then, visit Jiang Tiannan's neighbors to learn more about his daily life and estimate his daily consumption. Then use the time of Jiang Tiannan's last withdrawal, and push down how long it will take, this is the approximate time when the money is sent. ”

"I see." I suddenly realized, "But the first part is not necessary, right?" ”

"Why is it not necessary?" Xu Rui said simply: "The part of the unpacked money is less, plus zero or 10,000, 20,000, 30,000 or the like, according to Jiang Tiannan's consumption, you can verify whether the time of the second part is accurate, if it is both reasonable and reasonable, expand the speculated time by ten days, and let the monitor check it." ”

"That's right......" I gave a thumbs up, "The boss is the boss after all, and I'm convinced." ”

The living dead nodded, "I'm also convinced." ”

Li Yuan listened quietly from beginning to end, and he suddenly opened his mouth and said, "Give me this task to be responsible, I will calculate this." ”

Xu Rui thought for a moment, and he approved: "Hmm...... The computer doctor must have enough brains, Alley, so this key part will let you be fully responsible, remember to take into account all the factors that can spend money, a little negligence, the calculated time may have a fatal error with the correct time to send money! ”
