While the manhunt is in progress

687 Lock the target
Following Song He's reasoning, everyone quickly summed up the characteristics of the murderer in their minds, and began to try to determine the scope of the suspect.

Seeing this, Song He stopped talking, so as not to interrupt everyone's thoughts.

"So, the murderer must not be a local, and he has not lived there for a long time." Chang Qinghua looked at Song He and thought, "Because if he is a local, he will be prepared to live a suitable life even if he rents a house. Supplies.”

"And if you are a person who has settled in Gai County for a long time, your living habits will become normalized, and it is impossible to eat takeaway every day."

"That's right." Song He nodded: "In addition, the place he rents and his job will also restrict his living habits. At the same time, he also has a first place that will not be easily discovered and disturbed." A crime scene."

"At the scene of the first case, he killed the deceased and dealt with the body accordingly, and the more he did, the more traces would be left behind, so as long as we find the scene of the first case, we can find the evidence that points to Suspect leads."

Chang Qinghua was a little embarrassed: "But in the investigation of the first crime scene, there is no direction at all."

"Actually, there are." Song He said firmly: "Because the murderer's mental state was not stable when handling the dead body, and he didn't expect that human bones would be so difficult to handle, so from the wounds on the dead body, we I can see some traces of his negligence."

"Especially when he sawed off the body of the deceased, the lines on the cut were rough and uneven, so the saw he used must be a cheap woodworking hand saw held by one person, because only the saw teeth of this kind of saw can cause This kind of wound."

Chang Qinghua wondered: "Carpenter? Carpenter?"

"It's not a carpenter, because he is not skilled in using a carpenter's saw." Song He shook his head: "But precisely because of his unskilledness, he used his non-dominant hand to stabilize the body and his dominant hand to dismember the body."

"And judging from the oblique angle of the waist section of the deceased, he was using his left hand, so he was left-handed."

"At the same time, the cleaning of the wounds of the deceased is also of great concern to me."

Chang Qinghua asked: "Why?"

"Because it's too clean." Song He released two comparison photos again: "Judging from the cleanliness of the cleaning, although the murderer who committed the imitation crime did not do as well as the murderer in the original case, it is not far behind."

"However, the murderer in the original case was a surgeon, who was able to use certain medical equipment and resources, and probably refrigerated the corpse before discarding it."

"However, the interval between the death time of the imitation crime victim and the time of dumping the body was not long, and it was clear that some tools were used to clean it up so cleanly."

"After clarifying this point, I carefully observed the wound of the deceased, and found that the muscles and skin in the wound were somewhat similar to raw meat that had been washed in a slaughterhouse."

"Therefore, I conclude that the murderer used a high-pressure water gun to clean the fracture of the waist of the corpse, so that it can achieve this level of cleanliness that is difficult to achieve under normal circumstances."

"Car wash!" Just as Song He finished speaking, a voice suddenly rang out. Everyone looked, but it was Liu Xuejun who looked excited: "The deceased died at around eleven o'clock in the evening, and the time for dumping the body was two o'clock in the morning!"

"If the murderer is the car wash worker in charge of the night watch at the car wash shop, he is capable of completing this murder case without alarming anyone!"

Everyone was surprised at the same time, and almost at the same time thought that with the help of the equipment in the car wash room, the first scene could be completely cleaned up!

At the same time, due to work reasons, it is difficult for car washers to have time to carefully prepare three meals, so naturally they do not need the knives for cooking!
In an instant, everyone in the conference room became excited, Chang Qinghua and other police officers looked at Song He excitedly, waiting for Song He to give an affirmative answer!

Song He glanced at the nervous and excited Liu Xuejun, nodded and said, "I think the same way, so we'd better check all the car washes in Gai County as soon as possible, and look for the left-handed car wash worker who was on duty at night on the day of the crime."

After getting an accurate answer, Chang Qinghua and the others immediately reached an agreement, and began to arrange manpower to do related investigations, throwing everyone out in the blink of an eye.

With the exact investigation conditions in place, within an hour, a man named Cao Jintian came into the police's sight!
"Guys, I didn't disappoint you, did you?" Song He looked at the Juncheng police officer and the chief and deputy chief of the Gai County Police Station who looked much more relaxed, and said with a smile: "I can't help you with the rest. "

"If we still need Officer Song to arrest people, we are too useless." The chief of the Gai County Police Station waved his hands with a smile, and then praised: "But having said that, Officer Song really lives up to his reputation."

Just as Song He and a group of police officers flattered each other, Chang Qinghua, who had found out Cao Jintian's whereabouts, led Liu Xuejun straight to Gucheng.

Chang Qinghua took a deep breath, looked at the scenery passing by the window of the high-speed train, turned to Liu Xuejun beside him and said: "Xiao Liu, you have shown your face in front of the chief this time, you have to work harder and behave well. "

"The action of arresting Cao Jintian is up to you to lead someone to execute it."

Liu Xuejun's expression became serious for a moment, and he nodded: "Don't worry, Captain Chang, I will definitely capture Cao Jintian!"

"Yeah." Chang Qinghua was very satisfied with Liu Xuejun's attitude, looked around and asked in a low voice: "According to the current situation, Cao Jintian should be running after his female netizen in Gucheng, what do you think? ?”

Liu Xuejun was in high spirits: "I have read Cao Jintian's residence, there are many suspense novels, and judging from all aspects of the case, he should have considerable anti-reconnaissance capabilities."

"However, judging from their online chat records, Cao Jintian obviously has a deep affection for his online dating female netizen. However, he accidentally learned that this female netizen has stepped on many boats, so it is likely that he wants to use the black dahlia The means in the case were used to torture her."

"So I think, instead of everyone looking for Cao Jintian's whereabouts in Gucheng, it is better to send only a few people to find him, and most of them find his female netizens and wait for Cao Jintian to show up."

Chang Qinghua sat up straight after hearing this and patted Liu Xuejun on the shoulder with a smile on his face: "I can leave this to you with confidence!"

At dusk, Cao Jintian, who had fled to Gucheng alone, drove slowly on the street in his rented car.

After a while, the mobile phone in Cao Jintian's hand suddenly sounded a notification tone, and when he looked down, it was a text message: Where are you?

Glancing at the signature of the message, Cao Jintian went through what he was going to do for the first time in his mind, and then decisively replied a text message with angry eyes, asking the other party's location, and said that he would drive to pick it up.

The other party did not suspect him, and quickly returned to a position, and added a cute expression, but it completely ignited the anger in Cao Jintian's heart.

Looking at the phone coldly, Cao Jintian suddenly thought of the execution place he had worked hard to arrange and those cold and hard tools, and a sneer rose from the corner of his mouth.

Let yourself calm down, and replied that I will be there soon. As soon as Cao Jintian stepped on the accelerator, the car started to gallop in the darker and darker sky like an arrow off the string, and disappeared in the blink of an eye.
