Song Chuan's analysis is actually very thorough, although the murderer did not leave any traces about himself at the scene of Sun Haining's killing, but there must be clues to kill, such as RAGUEL using a strong magnetic field device to kill Zhao Guangming, it seems that there are no clues, but whether it is the device itself or the mailing process, there are traces to follow.

It's just that the murderer erased these traces through various means.

When I returned to the scene of Sun Haining's murder from the conference room, it was already half past five in the afternoon, and the sky had begun to darken, so Sun Baoqiang came with Song Chuan.

"Xiao Song, do you think that torn off page number is a clue deliberately left by Lao Sun?"

"Brother Qiang, I'm just guessing that there is also a possibility that the murderer tore off the page number and destroyed the evidence, of course, this is not necessarily to hide the identity of the murderer, it is very likely to mislead us, or the page number itself records nothing."

After all, the sixty-sixth page of the roster has disappeared, and no one knows whether Sun Haining recorded anything on it.

The blockade of the unit building has been lifted, but the 202 outdoor guard is still in place, and the keys have been kept by the criminal investigation team.

Opening the door still had a strong smell of blood, Song Chuan did not hesitate to go straight to the bookshelf, opened the box where he found the roster, and searched carefully.

"How's it going, did you find anything?"

Sun Baoqiang helped Song Chuan rummage through other bookshelves, but did not find the torn page numbers.

Song Chuan shook his head, frowning and looking at the bookshelf where the roster was found: "I didn't find it." ”

Could it be that his analysis was wrong, that page of the roster was not a clue left by Sun Haining, but was really taken away by the murderer?

But why?

Didn't the murderer take this page alone and leave a bigger flaw?

The two searched the scene again, but found nothing.

"Brother Qiang, I still haven't found out, my guess may be wrong, the roster that was torn off was not a clue left by Officer Sun, but was torn off by the murderer."

Sun Baoqiang patted Song Chuan on the shoulder: "It's okay, don't be discouraged, let's go back to the team first, the technical room is still doing technical analysis, and there may be more clues when the results come out." ”

Song Chuan could only nod and followed Sun Baoqiang out of the scene.

On the way, Sun Baoqiang lit a cigarette and handed one to Song Chuan: "Xiao Song, didn't you think that Lao Sun's family had a roster of the No. 1 Woolen Mill when you had a meeting just now, and he often read it." ”

Song Chuan nodded: "I think it seems that Team Chen doesn't care much about this, is there something hidden?" ”

If Sun Haining's family finds a roster of the criminal investigation detachment, there is no problem, but there is a roster of woolen mills, you must know that the woolen mill has been closed down for 16 years, and Sun Haining must have an important reason to turn over this roster every day.

Sun Baoqiang spit out an eye circle and sighed: "This matter starts with the fire in the woolen mill sixteen years ago. ”

"You know about the fire, right?"

Song Chuan nodded: "I was seven or eight years old at the time, I had just entered elementary school, and my aunt and brother-in-law worked in the woolen mill, and they also lived in the dormitory area of the woolen mill back then, and the house was also burned. ”

Sun Baoqiang nodded: "When the 718 fire in the woolen mill occurred, I had just been working for a few years, and I was still working as a police officer in the police station, but Lao Sun was already the captain of the reconnaissance team, which was the position of the Wang team. ”

After sighing, Sun Baoqiang began to explain to Song Chuan why Sun Haining's family had a roster of woolen mills: "Lao Sun had a sister named Sun Sufang, who was an employee of the woolen mill, who was burned to death in that fire, and died in front of Lao Sun. ”

"Didn't get out?"

Sun Baoqiang shook his head: "There is no way to save it, Sun Sufang's house was robbed back then, and when he fled, he locked the door of Sun Sufang's house, and no one came out when the fire burned, Sun Sufang's husband was not locked in the house on duty that day, and he almost burned to death when he saved Sun Sufang, it was Lao Sun who pulled him out, but there was only half a life left, and Lao Sun's leg was also broken." ”

"The fire of that year was characterized as an accident, but if it weren't for the thief, Lao Sun's sister and nephew would not have burned to death in the house, so Lao Sun has been looking for the thief back then."

"The dormitory area of the woolen mill is inside the factory, and outsiders can't get in, so Lao Sun targeted the woolen mill workers, and he has never given up for 16 years, so he has that roster in his hand, and the old people in the detachment have seen it and know about it."

Sixteen years ago, in the 718 fire, my sister and nephew were burned to death in front of my eyes......

I see.

The criminal investigation detachment, where everyone is working overtime, there are two homicides in one day, and the entire detachment is operating at maximum efficiency.

In the conference room, Chen Jianbin was still organizing the analysis of the case.

Wang Tao was speaking: "What is more important now is whether the killing of Lao Sun and Zhao Guangming's death have anything to do with it, and whether it should be handled together?" ”

Because Zhao Guangming's name was found in the page number of the disappeared roster, it was also marked emphatically, which made Wang Tao vigilant, whether it was possible that the one who killed Lao Sun was RAGUEL.

After working as a criminal police officer for so many years, what Wang Tao doesn't believe in the most is coincidence, although from the current point of view, Zhao Guangming and Sun Haining do not have any intersection, and even Zhao Guangming's death and intimidation of the letter, Sun Haining doesn't even know, but Zhao Guangming was an employee of the woolen mill back then, and Sun Haining has been investigating the thief who locked his sister in the room before the fire for so many years, and now the two have been killed one after another, if there is no connection, Wang Tao does not believe it at all.

Others are also thinking about Wang Tao's suggestion, and at present, it is very likely that the two cases are related, and it may even be the same murderer.

ANOTHER IMPORTANT POINT IS THAT THE HEIGHT AND AGE OF THE MURDERER THAT SONG CHUAN HAD JUST SPECULATED ABOUT COINCIDED WITH RAGUEL'S INFERENCE IN SOME CHARACTERISTICS.

But whether to merge the cases, Chen Jianbin has his own thoughts: "There is a certain coincidence between the two cases now, but it is only about the identity of Zhao Guangming's former woolen factory, which has been marked on the roster, and it cannot be made that there is a direct relationship between the two being killed." ”

"In this way, we will first investigate the two cases separately, but we must communicate in a timely manner, and if major related clues are found in the investigation, it will not be too late to merge the cases."

Since Chen Jianbin has determined the direction of work, everyone will naturally not object, Wang Tao began to report on the investigation around the detachment: "The Lijun organization force has conducted a visit and investigation around the detachment, and found some clues, but there is no obvious point, and no obvious suspicious persons have been found. ”

Chen Jianbin is mentally prepared for this, since the other party dares to call out the police, he must have made complete preparations, and it is unlikely that he will expose clues during the investigation.

In particular, there are three hotels around the detachment, and the flow of people is very large, but even if the possibility is small, it cannot be missed: "Focus on visiting and investigating the surrounding hotels and high-rise buildings, especially paying attention to external characteristics such as crutches and beards, and screening them in combination with Song Chuan's height, age and other characteristics." ”

"Yes, I'll arrange it."
