The thinking of the criminal police gradually became clear and tended to be consistent: one possibility is that the murderer coveted Zhu Zihua's property and burglarized, but unexpectedly woke up Zhou Lihua in his sleep, so in a hurry, he killed people and killed them, and finally swept away his property and fled; Another possibility is that after Zhou Lihua's death, according to An Qin's reaction, Zhu Zihua, who never turned off his mobile phone, left the company before the crime, and turned off his mobile phone uncharacteristically after the crime, which is also a major suspicion of committing a crime.

The top priority is to track down Zhu Zihua's whereabouts. When the criminal police were about to issue a notice to assist in the investigation, they unexpectedly received a call from Zhu Zihua.

Zhu Zihua burst into tears on the phone, begging the criminal police to find out the murderer no matter what, and avenge his deceased wife.

During the phone call with Zhu Zihua, Xiao Song learned that after Zhu Zihua left Qianxian County, he went to Kunming to negotiate a project there.

Unexpectedly, when he arrived in Kunming, a local leader in charge of bidding for the project announced that the bidding would be postponed for three days due to urgent matters. Zhu Zihua, who has been busy with business, planned to take advantage of the rare time of the past three days to relax and not want to be disturbed, so he turned off his mobile phone.

When he turned on his phone again, he unexpectedly saw many strange missed calls and text messages sent to him by the Public Security Bureau and company employees, and then he realized that after he left, his wife Zhou Lihua was killed.

Zhu Zihua was in pain, and told Xiao Song on the phone that he had bought a ticket and was on his way back.

When he saw the body of his deceased wife, Zhu Zihua cried loudly and fainted. When he woke up, he saw himself lying in the hospital's intensive care unit with salt water hanging from it, and several police officers were sitting in the ward watching him.

Xiao Song comforted Zhu Zihua a few words, and after he calmed down, he asked him about some situations.

Zhu Zihua showed his round-trip ticket and accommodation in Kunming**, and after Xiao Song instructed a criminal police officer to check it, it was confirmed that Zhu Zihua had indeed arrived in Kunming on the morning before his wife's death, and the local public security bureau used the video of Zhu Zihua's stay in the hotel to prove that what Zhu Zihua said was true. At the same time, the footprints of another man left at the scene did not coincide with Zhu Zihua's safety.

Thus, the suspicion that Zhu Zihua murdered his wife was basically ruled out. Who could have left this mysterious footprint? Is he the murderer of Zhou Lihua? Xiao Song and the people in the task force were confused.

At this time, another group of criminal police in charge of the investigation reported to Xiao Song that after Zhou Lihua's death, a withdrawal record appeared on her bank account.

This greatly encouraged the members of the task force, and they immediately contacted the bank to investigate this important clue.

Through the video footage on the bank's ATM, the police zeroed in on a man in his thirties with an obscene appearance. Xiao Song immediately ordered to retrieve the video materials left by the man, print them out as a reward notice, and post them widely within a 10-kilometer radius centered on the self-service bank.

Just when the task force was waiting to get clues from the masses, another group of police officers brought a piece of news that shocked the members of the task force.

Through various investigations into Zhou Lihua's life, the criminal police were surprised to find that half a month before the crime, three houses and a luxury car in Zhou Lihua's name were mysteriously transferred through an intermediary company, and the person who accepted the transfer was Xu Xin, who was burned to death in a bus accident a few days ago.

This puzzled the task force, Xu Xin was just an ordinary college student, how could he let Zhou Lihua, an art lecturer who taught at the university, transfer this huge amount of property to him?

Through the investigation of many teachers and students, it was found that Zhou Lihua was not Xu Xin's teacher, and almost no one believed that Xu Xin and Zhou Lihua were very familiar.

The seemingly uncomplicated case became confusing, which made Xiao Song very troubled. Xiao Song, who was confused, began to get excited because of a phone call, and the masses reported that the person in the photo in the reward notice posted by the Public Security Bureau resembled Xu Bin, an unemployed gangster in the town.

The criminal police team quickly dispatched and with the assistance of the local police station, they quickly arrested Xu Bin, who was staying in a hotel.

Xu Bin quickly confessed everything, and the ulterior secret behind the scenes shocked everyone.

Xu Bin, who has been unemployed, is idle all day long and does not want to make progress. He gathered a few idle people in the town, and often caused trouble in the local area, stealing chickens and dogs, and doing evil.

A few days ago, Zhu Zihua, the richest man in the local area, quietly made an appointment with Xu Bin. Zhu Zihua entrusted Xu Bin to do something for him, gave Xu Bin 20,000 yuan as a deposit, and gave Xu Bin 80,000 yuan in cash after the promise was successful.

Zhu Zihua learned from elsewhere that Xu Bin had mastered the skill of opening the safe with one hand, and he asked Xu Bin to sneak into his house quietly, open a safe in his wife Zhou Lihua's bedroom, and take out a small box sealed with fire wax from inside, which must not be opened without permission, and must be handed over to Zhu Zihua intact.

Seeing that there was so much remuneration, Xu Bin, who was often penniless, was naturally happy to agree. Zhu Zihua took advantage of the darkness to drive his high-end car, hid Xu Bin in the trunk, and unknowingly avoided the sight of the company's doorman and everyone else, as well as the surveillance probe at the door of the company, and hid Xu Bin in a warehouse of the company.

The reason why Zhu Zihua wanted to take Xu Bin into his company instead of handing over the side door key to Xu Bin was because he was also wary of this stealing Xu Bin who might have the idea of stealing from his house in the future. Of course, Xu Bin himself was very aware of Zhu Zihua's thoughts, so he had to obey Zhu Zihua.

After Zhu Zihua sent him into the company and went on a business trip to Kunming under the pretext of going on a business trip, Xu Bin obediently hid in the warehouse until after 11 o'clock in the evening, when he saw that there was no one else in the company, and Zhou Lihua's room was also turned off, so he quietly entered the small villa.

Xu Bin quietly opened Zhou Lihua's room, but unexpectedly, just after moving a few steps, he tripped over something and fell to the ground.

Xu Bin was shocked, for fear that Zhou Lihua would hear the movement and find out that he was stealing. Xu Bin had just gotten up from the ground and was about to escape, but he didn't hear any movement in the room.

Xu Bin was relieved, and the 100,000 yuan reward that Zhu Zihua promised to him made him feel at ease, with a hint of luck, he estimated that he didn't wake up Zhou Lihua just now, and decided to continue stealing.

Unexpectedly, when he turned on the glimmer flashlight covered with black cloth, he was frightened, and it turned out that it was a woman's body that tripped him.

I saw that the woman was lying on her side motionless, although Xu Bin was scared in his heart, but the temptation of the huge reward made him still bold to stretch out his finger and try the woman's snort.

At this moment, Xu Bin was completely panicked, the woman was no longer breathing, and her body was cold, and her two wide eyes were facing Xu Bin.

Xu Bin used a flashlight to shine a flashlight in the room, and the bed was empty, and at this time, he decided that the female corpse lying underground must be Zhu Zihua's wife Zhou Lihua.

Although I don't know who killed Zhou Lihua, Xu Bin, who is a thief, is unwilling to come empty-handed.

Seeing that the owner of the room was dead, after being scared for a while, Xu Bin's courage grew. He unhurriedly opened the safe in the room, which surprised him.

It turned out that in the safe, in addition to the small box sealed with fire wax that Zhu Zihua wanted, there were also a few piles of cash, more than a dozen bank cards and a diary.

Xu Bin found a plastic vest bag and put the small box, cash and bank cards into it. He glanced at the notebook with the help of a flashlight, and he was even more overjoyed, and on the second page of the notebook, there were many numbers recorded.

Xu Bin was ecstatic, these numbers, a group of six, obviously, are the passwords of those bank cards. Look at the back, it is all Zhou Lihua's life diary, and it is a diary written continuously. Xu Bin was naturally not interested in this, and he also put the notebook in his vest bag. Then he took out a bunch of keys from the small bag that Zhou Lihua put on the table.

Xu Bin tied the vest bag tightly to his body, and then slipped into the side door on the edge of the villa, and after several attempts, finally opened the side door with one of the keys, and disappeared into the night without noticing.

After listening to Xu Bin's confession, Xiao Song slammed the table and shouted loudly: "Xu Bin, you are lying." You know the policy, be lenient in confession, and strict in resistance. It's not the first time you've entered the Public Security Bureau, do you have to see a lot of evidence before you are willing to confess that you killed Zhou Lihua? ”

Xu Bin's face turned white with fright, and he tried his best to deny that he was just greedy for money and did not kill Zhou Lihua.

Xiao Song sneered and took out the mobile phone he had searched from Xu Bin.
