He Zhonghua fed back the information from here to Luo Cheng, and at the same time immediately sent someone to contact the relevant departments to see if Wei Ling had left the country.

He Zhonghua was also startled when Luo Cheng told He Zhonghua about his conjecture, this Li Shengyu was like a ghost, he killed Professor Wan obviously for the police, thinking of what he said, then he would never give up easily, and Professor Wan was by no means the first victim.

This made the whole case escalate abruptly, you must know that a top killer like Li Shengyu is already difficult to deal with, and now it is even more difficult to prevent it if he is still hiding in the dark, and the Qingzhou police can only defend passively, which will make the police very passive.

The only way to do this is to catch him as soon as possible.

But where to catch a cunning fox in the vast sea of people?

In Jinghu Villa, Li Xiao presented the topographical map around Jinghu Villa in front of everyone, it was already late at night, and the border guard was currently investigating, Xiao Wu was investigating Professor Wan's financial flows, and Li Xiao was monitoring Wei Ling and Professor Wan's phone calls all the time.

The room was very quiet, everyone was very nervous since Luo Cheng identified the murderer as Li Shengyu, and no one knew who Li Shengyu's next target of revenge would be, perhaps everyone present and their families.

Especially Luo Cheng, at that time, Li Shengyu named and wanted to take revenge on Luo Cheng's family, for which the family and Luo Cheng had a serious disagreement, and the family hoped that Luo Cheng could follow the arrangement and be transferred back to Shanghai immediately, but Luo Cheng rejected them again, which made the family very unhappy, and Luo Cheng had a quarrel with his family a few hours ago.

At this time, the Luo family was panicked, and many relatives had fled abroad in spite of the advice in order to protect themselves.

There are dozens of people in the Qingzhou Criminal Police Team, and their families and related personnel are hundreds, these people may become the next target, but the manpower is limited and there is no way to fully monitor, so only a few people can be selected for key monitoring, and Luo Chengcheng belongs to the target of key monitoring and protection.

He Zhonghua meant that if Luo Cheng was worried, he could withdraw first and replace other colleagues on top, but Luo Cheng refused.

The air in the room was a little oppressive, and now everyone couldn't help, the only thing they could do was to watch quietly.

Luo Cheng dragged his chin and connected several places on the map, and then marked the possible time of the crime.

"After the murderer killed Professor Wan, he didn't take the gate and side door, then the route he escaped may be the wall and waterway, the wall is more than two meters high, and sharp barbed wire is laid on it, it is not difficult to escape alone with Li Shengyu's skills, but it is another matter to take Professor Wan's body to flip through it, I have checked all the barbed wire and found no traces of climbing and flipping through it."

"You mean the murderer came by water and then took the body from the water?" Dai Lin asked.

Luo Cheng shook his head and rejected this statement.

"Impossible, assuming that Li Shengyu catches Wei Ling and uses her to contact Xie Yusheng's friend and prepare to escape, then he definitely doesn't want any accidents before he escapes, so he can't let people find Professor Wan's body, at least he won't allow it until he escapes, and if he takes the waterway, Wei Ling can't swim, even if he can, it will be impossible to swim out of the Mirror Lake, let alone take a corpse with him, so they can only go out through the gate!"

Gate?

Everyone was a little surprised, is this Wang Shengyu so bold?

"No, I've seen all the surveillance, and I haven't found Wei Ling or Wang Shengyu." Li Xiao is very confident in his eyes, he has not only seen the surveillance at the door, but also the surveillance around him.

"What do you mean by looking? Monitoring? It seems that you can only see the two people in the cab and the co-pilot, right? Are you sure you can see the person sitting behind you? Are you sure you can see the person in the trunk? Are you sure that no one cooperates with them? ”

Luo Cheng asked a series of questions Li Shengyu was speechless, really, if the suspect was hiding in the trunk, then he really couldn't see anything.

"A veteran like Li Shengyu has full confidence in himself, he will never use the time-consuming and laborious method of swimming, so I boldly predict that he came in by car, he has no accomplices, the person who drove should be hired by him, this person may be a private car owner, the car should belong to the low-end car, otherwise he will not accept this kind of business, the owner drove the car into the hotel and was opened, with the ferocity of Li Shengyu, it is estimated that this person also had an accident, and now go to investigate the missing person in the last week, It mainly concentrates on taxis and private car owners who run Didi. ”

Luo Cheng overturned all his previous judgments, he thought of his opponent too cautiously, although Wang Shengyu has a strong reconnaissance ability, he is very confident in himself, and he is very casual in killing, he should be a very bold person, if he kills Professor Wan, he doesn't need to play so many tricks to come in directly.

Moreover, Luo Cheng also felt that Li Shengyu's capture of Wei Ling was not a set goal, but a temporary intention.

Although everyone was skeptical, they did it anyway.

At three o'clock in the morning, Luo Cheng appeared by the lake alone, he held a cigarette in his mouth, and his expression was solemn and deep in the flashing firelight, and at this moment Luo Cheng's mind was still thinking about Li Shengyu's strange behavior.

If he didn't come by himself, then who informed him?

Wang Jieyu?

How did Wang Jieyu do it? Does she still have an accomplice?

"What do you think?" Dai Lin walked over and asked.

Luo Cheng spit out a smoke ring and said with a solemn expression: "It is certain that Lu Yan's death is directly related to Li Shengyu, Lu Yan's death time is after the ranger, if Wu Cheng and Li Shengyu are also related, then Li Shengyu must have returned to Qingzhou to kill Lu Yan after finding Wu Cheng, and then ran to Jinghu Villa to kill Professor Wan and took Wei Ling away to prepare to escape." ”

After speaking, Luo Cheng shook his head again and said: "No, this is not the case, we don't have any evidence to prove that Wu Cheng has anything to do with Li Shengyu, and the death of the forest ranger is not necessarily done by Li Shengyu, and if he wants to kill Lu Yan directly, why kill the forest ranger and then run back to kill Lu Yan, isn't this an extra move?" ”

Saying that, Luo Cheng picked up the pen again and connected Jinghu Villa and Qingzhou.

"If it would be much more reasonable for Li Shengyu to rush to Jinghu Villa to kill Professor Wan after killing Lu Yan, then who killed the forest ranger? Could it be that Wu Cheng did it? ”

A picture appeared in Luo Cheng's mind, Wu Cheng wrote a suicide note in the hut of the bamboo forest and pressed it under the table, just when he was about to go out, the ranger came, Wu Cheng had a quirky and cold personality, and the ranger asked two more words when he found out that he was leaving, which made Wu Cheng suspicious, so he simply killed him while the ranger was not paying attention, and after killing the ranger, he dismembered him and threw him into the kennel.

There was a strong smell of blood in the air, and Wu Cheng stood aside and looked coldly at his expression, with a happy smile of revenge on the corner of his mouth.

If that's the case, then wasn't his suicide note written in vain? No, regardless of whether the ranger was killed by Wu Cheng or not, he would never leave a body in the kennel to make the police suspicious when he was completely free.

Judging from the suicide note, whether it is the handwriting or the tone, it was written by Wu Cheng himself, so he concocted the suicide note to escape the blow, Li Shengyu did not have the time to commit the crime, so who killed the ranger? Could there be another murderer?

Dai Lin smiled and said: "I'm here to inform you of a good news, according to your arrangement, we conducted an investigation, and screened a man named Hu Wei among the suspicious targets, this person is a Didi driver, no official job, his hometown is Chongqing, has been missing for four days, three days ago his friend reported the case, and now this case is still under investigation, he said that the white Kia of the posture drove into Jinghu Villa from the suburbs of the city four days ago, the time was 3:50 in the afternoon, and then he ate in the hotel, opened the room and slept for a while, Left the villa at nine o'clock in the evening, and got on the highway at half past nine. ”

"It can't be going to Yunnan, right?" Luo Cheng asked.

"That's right, it's Yunnan!"
