The book-crossing case happened! The villains all want me to go to jail

After an in-depth investigation of the barbecue restaurant's competitors, the police found that one of the competitors had been in poor operating conditions recently and was facing the risk of bankruptcy. The owner had repeatedly expressed his jealousy and dissatisfaction with the barbecue restaurant's booming business in private, and even threatened to teach the other party a lesson in front of his employees.

On the night of the poisoning, the boss's whereabouts were unknown and he had no reliable alibi.

During the investigation of the food supplier, the police found that the procurement channels of a batch of key ingredients were abnormal. The long-term regular supplier was replaced before the incident. The new supplier was not fully qualified, and the food it provided had loopholes in the storage and transportation links. Further investigation found that the new supplier had financial dealings with an internal employee of the barbecue restaurant.

In addition, the police discovered through surveillance video that a suspicious figure appeared near the back kitchen of the barbecue restaurant the night before the incident. Although his face could not be seen clearly, his figure was similar to that of the employee who had dealings with the new supplier.

These discoveries made the case seem clearer and also made the police realize that Xie Xuan'an's proposal opened up a new breakthrough in solving the case.

The police quickly launched a comprehensive and in-depth investigation. After several days of sleepless investigation, they finally identified the murderer and arrested him.

The murderer was taken to the interrogation room. He lowered his head, his eyes revealing deep despair and stubborn resistance.

"Why did you poison the barbecue restaurant?" the police asked sternly.

The murderer bit his lips tightly and said nothing, as if his mouth was glued shut.

The police raised his voice: "Your actions have caused many people to be injured and some even lost their lives. You must be held accountable for your crime!"

The murderer raised his head, looked at the police coldly, then quickly lowered his head and remained silent.

The police slammed the table and shouted, "Tell the truth, don't try to get away with it! We have a lot of evidence in our possession, and you can't escape the blame even if you don't tell the truth!"

The murderer trembled slightly, but still kept his lips tightly closed.

As time went by, the atmosphere in the interrogation room became more and more oppressive. The police kept changing their strategies, sometimes sternly reprimanding, sometimes patiently persuading.

"As long as you tell the truth, we will consider giving you a lighter sentence. This is your only way out." The policeman's tone was suggestive.

The murderer's expression relaxed a little, but soon returned to indifference.

Several hours passed, and the murderer still refused to speak. The policeman was a little tired, but his eyes were still determined.

"Think about your family and your future. Do you want to bear this crime for the rest of your life?"

There was a hint of panic in the murderer's eyes, but it was quickly covered up by toughness.

The police continued, "If we can find out that you did it, we can definitely find out the reason behind it. If you don't tell us now, you won't have any chance of getting a lighter sentence when we find out."

After a long psychological struggle, the murderer finally couldn't help but say: "Someone gave me money to do this."

The police immediately asked: "Who gave the money?"

The murderer hesitated for a long time before hesitatingly saying, "It's... it's Shao Liechuan."

The police asked: "How did you get the money?"

The murderer confessed: "He gave me an anonymous bank card and wrote the password on a piece of paper."

The police immediately launched an investigation into the bank card and found that the money was transferred through multiple anonymous accounts. The flow of funds was complicated and it was difficult to trace the direct connection to Shao Liechuan. Moreover, the murderer did not leave any evidence directly pointing to Shao Liechuan during the process of receiving and using the money.

Although the police found out where the money went, due to the complexity of the fund flow process and the lack of evidence, they were unable to convict Shao Liechuan for the time being.

The police decided to conduct a secret investigation on Shao Liechuan, not letting go of any clues, and vowed to uncover the truth behind the poisoning case. The police conducted a close and secret observation on Shao Liechuan for many days, but all of Shao Liechuan's activities during this period were normal.

He went to school or work on time every day, had a regular work schedule, and communicated normally with colleagues and partners. After get off work, he went straight home or participated in common social activities, such as dining with friends and working out, without any suspicious behavior or contact.

His communication records did not show any unusual contact with the poisoner or other suspicious persons, and there was no large amount of capital flow or unknown funds in his financial affairs.

Although the situation seemed normal on the surface, the experienced police officers did not let down their guard, as they knew that the suspects might try to conceal their crimes and connections.

The police continued to hold on, not letting go of any subtle changes and clues, waiting for the moment to reveal the truth. Although they observed Shao Liechuan for a long time, they did not find any suspicious clues related to the poisoning case.

When the investigation got stuck, there was a heated discussion within the police force. An old police officer spent several days in an office filled with files, burying himself in past case materials.

Late one night, the old police officer rubbed his eyes and prepared to rest when he accidentally put several seemingly unrelated case files together. Suddenly, Xie Xuan'an's name came into his sight.

The old police officer was nervous and opened the file of a theft case from two years ago. There was no sign of intrusion at the scene, but valuables were missing. When checking for suspects, Xie Xuan'an was ruled out because of his alibi.

Then, the case of fraud from last year was brought up again, and Xie Xuan'an's name appeared again, and he was also cleared of suspicion due to evidence.

The old police officer frowned and compared the information related to Xie Xuan'an. He found that he was calm and composed every time he was questioned, and his answers seemed perfect but deliberate. In both cases, he had a weak and easily overlooked connection with the key figures.

After thinking and analyzing, the old police officer had strong doubts. He firmly believed that it was no coincidence that his name frequently appeared on the edge of different cases, and Xie Xuan'an might be hiding a criminal intention.

So, the old police officer raised his findings and suspicions at an internal meeting of the police station, and everyone decided to launch a comprehensive investigation of Xie Xuan'an again, leaving no details unexamined.
