Then at the scene, the most favorable evidence found was this bloody fingerprint.

After the investigation of the crime scene is completed, it is necessary to find out if there are any traces of the murderer left outside.

The scene of the crime is outside the Lujiaba Industrial Park at the junction of urban and rural areas, and most of the people who come to patronize this foot massage shop are also workers from surrounding factories.

However, I deduce that the time of death of the deceased was between 23 o'clock in the evening and 1 o'clock in the morning. At this time, on the road outside the Lujiaba Industrial Park, there are hardly any pedestrians in sight.

Even though there are many shops next to this pedicure shop, most of them are restaurants and car shops, and by 11 p.m., they are already closed, so it is quite difficult to find witnesses here. Therefore, I have ruled out this direction of investigation.

Then there is also the search for a monitoring probe, but there is only a monitoring probe two hundred meters away from the left of the pedicure shop, and this probe is not facing the direction of the pedicure shop, it is in the opposite direction of the pedicure shop.

Three hundred meters to the right, there is a monitoring probe hanging outside the gate of a light bulb factory, but the monitoring range of this probe is very limited, it is facing the road and the gate of the light bulb factory, so here, I still have no findings.

So now I can be sure that the foot massage shop is in the blind spot of monitoring, so it is relatively difficult to find the murderer from the monitoring.

Putting these circumstances aside for now, I first investigated the identity of the deceased, because I suspected that the murder of the deceased was not necessarily a robbery and murder, and perhaps the murderer had other motives. If the murderer had other motives, then the murderer should be someone the deceased knew, so I decided to start with the deceased's social sphere.

The police quickly investigated and clarified the identity of the deceased. The deceased's name is Zheng Xiaoxiao, 28 years old this year, unmarried, from Changling Town, Wanzhou District, at the end of 2008, he co-rented this store in Lujiaba and engaged in the foot massage industry.

In the investigation of Zheng Xiaoxiao's social relations, it was found that Zheng Xiaoxiao's social relations were extremely complex and had multiple ex-boyfriends. And the ex-boyfriend who just broke up with him is a partner of this foot massage shop, and he can also be said to be an investor.

The ex-boyfriend of Zheng Xiaoxiao is named Zhang Guangsong, 32 years old this year, who has a criminal history and has been in prison for three years, and the reason for his crime is related to gangsters. After being released from prison, Zhang Guangsong still had contact with lawbreakers in society and was a figure walking on the edge of crime.

And importantly, Zhang Guangsong does not have any legitimate occupation, mainly working for people in some entertainment venues. He met Zheng Xiaoxiao in early 2008, and the two quickly established a relationship. and invested 40,000 yuan in Zheng Xiaoxiao's foot massage shop. However, after the two broke up, Zhang Guangsong asked Zheng Xiaoxiao to return the 40,000 yuan to him, but Zheng Xiaoxiao refused all the time, and the reason for the refusal was that the 40,000 yuan was used as a breakup fee.

Zhang Guangsong has approached Zheng Xiaoxiao many times and asked him to repay the money, but Zheng Xiaoxiao refused. Zhang Guangsong said that Zheng Xiaoxiao was an unreasonable woman and valued money. His claim was confirmed by our subsequent investigations.

However, it is precisely because of the financial entanglement between Zhang Guangsong and Zheng Xiaoxiao that he has become our biggest suspicion.

But I don't think this case will be so simple. Of course, this case is by no means so simple, and if it were, I would not repeat it here.

The possibility that Zhang Guangsong was the murderer was quickly ruled out. First of all, the bloody fingerprints did not match Zhang Guangsong, and secondly, Zhang Guangsong was helping out at a KTV on the night of the crime, and many people testified for him.

After the first suspect was ruled out, the results of the fingerprint comparison by the forensic center were also available. But this result is the same as most of the time, that is, in the fingerprint center, there is no fingerprint that matches it.

This indicates that the murderer is a first-time offender, or a wanted person with a criminal history but has not been arrested.

Of course, I am more inclined to be a first-time offender, because when a wanted criminal is wanted, he mostly changes his appearance and is low-key, and it is impossible to commit such an extraordinarily cruel bloody case. Unless psychopathic.

In the subsequent investigation, the suspicion of several people closely related to Zheng Xiaoxiao was also ruled out, and the whole case came to an impasse.

So I simplified the idea of the whole case, as if it was a case of robbery and murder. But as a robber, wearing gloves and carrying a murder weapon, it shows that he was carefully planned and premeditated. Then this robber must have learned that Zheng Xiaoxiao had a large amount of cash left in the store, and perhaps the murderer had stepped on this store before. So why did he choose to get his hands dirty on this night? Either there is a lot of turnover today, or the deceased has just withdrawn money from the bank.

The day of the incident was a Tuesday, not a holiday, and I believe that the turnover on this day will not be too high. But the murderer planned to choose to do it on this day, which means that he is aiming at this day, and the foot massage shop has a lot of cash.

Therefore, I deduce that the deceased must have gone to the bank to withdraw money before his death.

Along this line of thought, the police investigated the deceased's financial situation. Sure enough, at 4 p.m. on the day of the crime, the deceased withdrew 8,000 yuan in cash from a nearby bank ATM.

Why did she withdraw so much cash? The first thing that comes to my mind is rent. After understanding the landlord of the façade, sure enough, the day of paying rent was on this day or two.

Then I now have another hypothesis, maybe when the deceased took the money, she was already targeted by the murderer. Or maybe the killer knew she had taken the money.

So we retrieved the surveillance video in front of the bank and the surveillance video of Zheng Xiaoxiao withdrawing money from the ATM.

In the surveillance video, there was a major discovery, Zheng Xiaoxiao came to the door of the bank in a battery car driven by a strange man. The man looked very young, about 175 centimeters tall.

When Zheng Xiaoxiao withdrew the money, the man had been waiting outside the bank. After Zheng Xiaoxiao took out the money, he went straight to the back seat of the battery car driven by the man.

At this moment, this man with a black helmet, a brown jacket, and blue pants became the object of our suspicion.

Actually, I've been watching the surveillance because I want to see what kind of shoes this man is wearing. Because at the scene of the murder, the shoe prints of the murderer are the shoe prints of leather shoes, if we can see the shoes worn by this strange man, we can quickly determine whether the direction we suspect is right or wrong. Unfortunately, in the blurry surveillance footage, I was never able to see what shoes he was wearing.

Of course, since there are new clues and investigation directions, then we have to find this man as soon as possible, whether he is a criminal or not, and we will know as soon as we ask.

The strange thing is that this person has already left Wanzhou and does not know where to go.

This undoubtedly increased his suspicions.
