It is difficult to walk, not in the mountains, not in the water, but only in the repetition of people's hearts.

The pin, a common gadget in the office, was accurately pierced into the sciatic nerve, which has the most abundant neurons, causing Liang Wenbo to die of cerebral hemorrhage due to severe pain. The murderer's modus operandi has been found, but there are no clues to the entire crime process and motive for the crime, and it is too difficult to delineate the scope of the suspect with only a pin.

Ma Wanliang has already begun to investigate the lost documents, hoping to follow this clue to find Wang Kai, who stole the documents. Because Wang Kai had pretended to be an electrician to come to the Legal Mansion before, as long as he got the registration book of the security room and found the impostor among the outsiders, he could be locked up quickly through the surveillance video.

Time is running out.

Xu Jiahui suddenly said: "This kind of pin should be rare." Then she analyzed: "There is a metal cap at the end of an ordinary pin, which is convenient for applying pressure to pierce the object, but this one does not, it should have a plastic round head installed on the tail to make it easier to pinch and exert force, such a pin is much more expensive than the ordinary one." ”

Gu Tianyou immediately said goodbye to Xu Jiahui, and when she rushed home, it was already half past three in the middle of the night, Fang Le'er was lying on the sofa, and she woke up as soon as she entered the door. Gu Tianyou's heart is warm, but at this moment, he can't care about talking about love and talking about his heart. Hurriedly asked, "Le'er, do you remember who in the office used a plastic pin and was able to open the door of the reference room?"

Fang Le'er thought carefully for a while, and said, "I seem to have seen this kind of pin you said in the small conference hall of Liang Bida's office, and I don't have an impression of other places." ”

Gu Tianyou asked again: "Then do you know that there is anyone in the office who knows how to give injections to people, or who has some medical knowledge and practical experience?"

Fang Leer said: "Liang Bida, he likes to study Chinese medicine, often goes to acupuncture and cupping, and he still has the key to the data room, but he should be the person who has the most reason to kill Liang Wenbo." ”

There are many kinds of motives for committing crimes, and there are random, such as killing people in the heat of passion and killing people in silence. There are premeditated ones, such as vendetta and love killing. The former is a sudden increase in murderous intent, and the latter accumulates murderous intent. Either way, all Gu Tianyou needs now is a new direction to detect.

It was already four o'clock in the morning when I hurriedly came to the Legal Building, and there were people from the criminal police team of the Municipal Bureau who were still collecting evidence, and the security of the building and the security of the Beida Law Firm had also arranged for night shift personnel to cooperate. The focus has been on surveillance footage. Gu Tianyou was dressed in a military uniform, carrying the sign of the third-level superintendent on his shoulders, and came to Zhao Wanchen, who was in charge of the scene, in a grand manner.

"I just came from the technical brigade of the corps, and the autopsy report has made new discoveries, and the cause of death of the deceased was not falling from a building, but being pricked to death with a needle. ”

"Who allowed you to participate in the investigation?" Zhao Wanchen pulled his face, took the autopsy report and looked down, "Pin?"

"Team Dai showed me the on-site inspection records in front of you, do you think I am qualified to participate in the investigation?" Gu Tianyou didn't want to involve Xu Jiahui, so he avoided the important and said lightly: " The murderer pierced the needle from the sciatic nerve of the deceased Liang Wenbo, and the severe pain caused Liang Wenbo's cerebral blood vessel to rupture, and the murder weapon used was a kind of pin that was not unusual, and I learned after asking Fang Leer, an intern employee of the firm, that there was this kind of needle in the small conference room of Liang Bida's office in the firm, and Liang Bida himself was a fan of Chinese medicine and was good at acupuncture, so I suggested that Liang Bida's office on the 16th floor be searched immediately. ”

Zhao Wanchen had already recognized Dai Xiaolou's judgment and ruled out Gu Tianyou's suspicion, he was a workaholic, and solving the case was the first place in his heart, he pondered for a moment and said, "It's an investigation direction." As he spoke, he immediately called the security guard on duty at the office and ordered him to immediately open Liang Bida's office to cooperate with the search.

The security guard said that he was very embarrassed at first, but Zhao Wanchen warned him that this was a homicide case, and that it was a citizen's legal obligation to cooperate with the investigation, and that even if Barrister Liang was present, he had to cooperate unconditionally, and if he refused, it would mean that there might be a major suspicion. This guy fart, who can't wait to write a charter, scared the security brother into confusion, and took out the key in a hurry.

In the small conference room of Liang Bida's office, Gu Tianyou and Zhao Wanchen sensed that something was wrong as soon as they walked in. It has been carefully cleaned, and there is a big difference between a daily cleaning and a cleaning done to sweep up evidence. The former is prone to leave dead corners, and it is rare to deliberately place and arrange some details. The latter, on the other hand, will definitely take into account every link that may reveal flaws.

All sins leave a mark.

Gu Tianyou and Zhao Wanchen led several criminal policemen to conduct a careful search, and soon found the kind of pin with a round plastic head as Xu Jiahui said, and the length of the plastic head after removing it was exactly the same as the one taken out of Liang Wenbo's body. And Zhao Wanchen found a crack and deformation in the corner of the table under the conference table, and even made a simple repair to cover it. Subsequently, the comrades of the technical department who arrived at the scene made more detailed on-site investigation work, which further proved that Liang Bida was suspected of committing a major crime!

Small fragments of broken glassware were found in the cracks in the corners, several galvanized layers of the chair legs in the conference room collided and fell off, and suspicious hairs were found in the gaps between the marble of the window sill and the staircase, all kinds of signs reminded Zhao Wanchen that someone may have suffered greatly here, he touched a glass, knocked over the chair, and broke the corner of the table, he was in pain, and even climbed to the edge of the windowsill out of control, and finally he struggled to die here.

There is a good chance that this place is the scene of the first crime!

If the fifteenth floor was just a corpse dumping site, then the suspect would definitely show his horse's feet when carrying the body. Zhao Wanchen immediately ordered to access the surveillance video of the fire escape between the elevator and the 16th and 15th floors between five and half past eight last night.

Surveillance footage shows that at 7:40 a.m., Liang did take the elevator down to the 15th floor once, but he did not carry anything.

The location where Liang Wenbo's body fell corresponds to the data room on the fifteenth floor, while Liang Bida's office is three rooms further south, assuming that it is a murder scene, if the body is thrown from there, the location of the fall should be further south. However, the surveillance video proved that there was no indication that Liang Bida had moved the body to the data room on the fifteenth floor. Assuming that he was the murderer, how did this corpse be thrown downstairs? Zhao Wanchen couldn't think of why, and Gu Tianyou couldn't figure it out.

In desperation, Gu Tianyou called Professor Li Yunqing. I want to hear the opinion of the old criminal investigator. After stating the facts of the case and the situation at the two scenes, the old professor fell into a long silence. After a while, Professor Li Yunqing suddenly asked, "There was a strong wind in Jianye last night?" Gu Tianyou said: "It's windy, but it shouldn't be enough to affect the parabola where the corpse falls." Li Yunqing asked again: "What if this corpse is tied and fixed on a rope and suspended in the air?" Gu Tianyou thought for a while and said, "It will definitely be blown back and forth by the wind." ”

hung up the phone and immediately called Xu Jiahui again. The clothes Liang Wenbo wore before his death had traces of fiber wear on both shoulders and armpits, which he thought was caused by the transportation of the corpse, but after careful screening again, he came to a new conclusion that it was caused by friction with another fiber material.

The problem of throwing the corpse was solved, and the first crime scene was established.

Gu Tianyou called Zhao Wanchen aside and analyzed: "The case is basically clear, assuming that the murderer is Liang Bida, he took the elevator to the fifteenth floor at 7:40, entered the data room and opened the window, leaving the footprints of the deceased and clothing fibers, faking the first scene, and then returning upstairs, at about 8:30 to complete the body disposal with the help of the wind through the sling, and then calmly cleaned the small conference room. ”

At this point in the investigation of the case, Zhao Wanchen had seen Gu Tianyou's influence on Dai Xiaolou, and at the same time, he had to recognize Gu Tianyou's ability, so he didn't dare to underestimate it, he asked in a modest tone: "Why did Liang Bida do this?"

Gu Tianyou nodded and said: " The Ma detachment went to visit other employees of the office to investigate the loss of data, I think he made the focus of the investigation wrong, we should immediately report to him the investigation here, and immediately control Liang Bida first, first, this person's identity is not trivial, and the Ma detachment must personally lead the team to be deterred; 。 ”

Zhao Wanchen listened attentively, and it took a while before he suddenly came back to his senses, and immediately said, "I'll call right away." ”

In Liang Bida's office, Gu Tianyou sat on a chair and fell into deep thought.

Zhao Ziming's kidnapping and the death case of the Bida Law Firm all happened in one day. Xi Zhiming's revenge plan is menacing. At this point in the investigation of the case, Liang Bida is very suspected of murder. It's just that with Barrister Liang's shrewdness and strength for many years, how did this kid Xi Zhiming force him to do this case?

Ma Wanliang hurried over, with beads of sweat on his chubby cheeks, this old fritter went home last night in the name of investigating information and slept peacefully, and after receiving Zhao Wanchen's case report early in the morning, he immediately realized that this was a good opportunity to make a name for himself. Liang Bida's identity is not trivial, he is a well-known figure in both political and business circles, he has friends and enemies, and he has great influence but does not belong to the real power faction. If this case is put on his head, it will definitely cause a sensation.

A barrister who has been dealing with crime for many years has masterminded an ingenious murder case that has been solved overnight, and the investigator will undoubtedly become famous overnight when such a press release appears.

Zhao Wanchen stood aside like a fool and listened to Gu Tianyou and Ma Wanliang discussing the case as if they were sitting on the ground and sharing the spoils.

Gu Tianyou: "The horse detachment came in time, and Liang Bida's side is all under control?"

Ma Wanliang is no better than Zhao Wanchen's mallet, he is well-informed and sleek, he has long heard of Gu Tianyou, and knows that this young man has a mysterious background, it is rumored that he is the apprentice of the Dai Corps, the godson of the old hall director Guan Peiyuan, and he is deeply valued by the political commissar of the provincial department Bai Fenglin. Although it is only a small third-level superintendent, it is definitely not to be underestimated.

He politely said: "It's all arranged, I'll come over to review the investigation, and if there are no mistakes, I'll arrest people in person." ”

Gu Tianyou said: "The investigation of the case is carried out under your full guidance, Captain Zhao is in charge of the scene part, I am only responsible for delivering the news here on behalf of several leaders, when to arrest people, how to write the report, it should be your two business." ”

Ma Wan's conscience was secretly happy, his face was silent, and he said: "It's not appropriate to do this, our working principle has always been to respect the facts, seek truth from facts, Assistant Gu worked tirelessly in the investigation of this case 616161616161"

"Don't talk about the horse detachment. Gu Tianyou waved his hand and said categorically: "I'm here to help, the case is under your command and supervision, and Captain Zhao will carry it out!"

Ma Wanliang looked at Gu Tianyou a few times in shock, but he couldn't see the temptation, and finally nodded: "Okay, I'll arrest someone now!"

Zhao Wanchen was on the side, confused and annoyed, looking at Gu Tianyou's eyes, but with a little more respect.
