"It's possible!" Lin Jiangbei nodded.

At this time, Wang Jiangang, who had been standing awkwardly beside him, touched the back of his neck and opened his mouth: "Bureau, these cigarette butts may also be the ...... left by the old cigarette guns under my hands."

"Maybe?" Zhou Fengshan's fierce gaze swept over.

"No, no, no, it's possible," Wang Jiangang was so frightened that he quickly changed his words, "It should be those old smoking guns left." At that time, after investigating the crime scene in the main hall, the guys hid here and smoked for a while. ”

"Wang Jiangang, Wang Jiangang, how did you become the detective captain?" Zhou Fengshan hated to stomp Wang Jiangang's foot, "You don't want to think about what kind of case this is?" Allowing his subordinates to smoke here? ”

"Bureau, humble and guilty! Guilty of contemplation! Wang saw that the sweat on his forehead was rising, and he lowered his head and did not dare to explain.

Zhou Fengshan shook his head and didn't say anything more. He also understands the bad habits of these policemen under him, not to mention smoking at the scene of the case, or even and pee at the scene of the case.

Wang Jiangang's cigarette guns were able to endure until they had completed the investigation of the murder scene in the main hall before hiding in the corner of the patio outside to smoke, which was already a face-saving experience for Deputy Director Cao.

It's a pity that he rejoiced in vain just now, thinking that he had found a new clue!

But at this moment, Lin Jiangbei shook his head and said, "Captain Wang, among these cigarette butts, one of them should not have been left by your subordinates. ”

While speaking, Lin Jiangbei took out a pair of tweezers from his satchel, then lay on the edge of the ditch, and carefully used the tweezers to take out one of the five cigarette butts in the corner of the drainage ditch.

"Didn't they stay? Consultant Lin, how do you see that? Wang Jiangang looked at Lin Jiangbei puzzled.

Lin Jiangbei did not rush to answer Wang Jiangang's words, but squatted on the ground, carefully observed the cigarette butts on the tweezers for a while, and finally put the cigarette butts under his nose and sniffed for a while, and then slowly stood up.

"Xiao Zhang," Lin Jiangbei explained to the police officer in the physical evidence room who was following him, "Take out the remaining four cigarette butts in the ditch and put them in the physical evidence bottle for preservation." ”

"Yes!" Xiao Zhang answered, and hurriedly took out a pair of tweezers and a few small glass bottles from his satchel, took out the four cigarette butts in the drainage ditch, and put them into the four small glass bottles for preservation.

When Xiao Zhang took the cigarette butt, Lin Jiangbei took out the white paper from the satchel, spread it on the stone table next to the patio, and then put the cigarette butt held on the tweezers on the white paper, then dodged to the side, and said to Zhou Fengshan and Wang Jiangang, who had been following him with doubts on their faces: "Principal Zhou, Captain Wang, you two come to see what is abnormal about this cigarette butt?" ”

Zhou Fengshan and Wang Jiangang stepped forward and looked down at the cigarette butts on the white paper. Soon, both of them saw something unusual about the cigarette butt. It is a cigarette rolled by hand in straw paper.

Wang Jiangang immediately understood why Lin Jiangbei was able to judge with such certainty that this cigarette was not left by his subordinates. Because his subordinates all buy cigarettes to smoke, and no one rolls cigarettes by hand.

Oh, that's not right! Lin Jiangbei is not familiar with his subordinates, how do he know that his subordinates don't like to smoke cigarettes by themselves?

As if he understood the question in Wang Jiangang's heart, Lin Jiangbei smiled and asked, "Captain Wang, the salaries of the detectives under your command are not low, right?" ”

According to the system of the Republic of China, the same is a police officer, but the police officer is a civil servant, and the salary he receives is called "official salary". On the other hand, the chief police officer does not have the status of a civil servant and receives a salary called "salary".

Among the chief police officers, they are divided into two levels: sergeant sergeant, each with three grades: A, B, and C.

To be able to serve as a backbone member of the detective team of the provincial capital police station who was brought by Wang Jiangang by his side, the level must have reached the level of sergeant, so it is not extraordinary, just in terms of salary, even if he takes the lowest sixth-class salary, he has 21 yuan of legal currency per month.

At that time, the price of domestic cigarettes, 20 packs, was basically about a dime. In other words, even if Wang Jiangang's subordinates receive the lowest salary of a sixth-class sergeant, they can buy at least more than 200 packs of cigarettes per month. In order to save money, how could they roll cigarettes by hand and smoke?

In addition, working in a prominent department such as the provincial capital police department, no matter what, you have to talk about a platoon. Even if someone really can't afford to smoke cigarettes for some reason, they will at least put a box of cigarettes in their pockets to meet the situation, and secretly roll up a cigarette to smoke when no one is around.

Therefore, Lin Jiangbei boldly judged that this hand-rolled cigarette butt was not left by Wang Jiangang's men.

And Wang Jiangang's answer also confirmed his expectations, "It's okay!" Basically, you can get more than 20 yuan a month. ”

"Then none of them smoke homemade cigarettes, do they?" Lin Jiangbei asked again.

"Not really!" Wang Jiangang replied.

"That's pretty much what you can say about it, this cigarette butt wasn't left behind by your men. However, this point still needs to be verified by you, Captain Wang. See if any of your men smoked homemade cigarettes at the site when they visited the site three days ago. Lin Jiangbei said.

"Those guys are also coming with me this time, I'm going out and asking!"

Wang saw that he was about to leave as soon as he raised his feet, but was stopped by Lin Jiangbei again, "Captain Wang, it's best to ask them about the brand of cigarettes they smoked at that time." ”

"Okay, I got it!"

Wang Jiangang hurriedly walked out.

A few minutes later, he walked back and said to Zhou Fengshan and Lin Jiangbei: "I have already inquired, there were three people smoking at that time. One of them smoked two. The cigarette brand smoked by the two smokers was Zhongyuan domestic cigarettes, and the other two smoked Harddoor cigarettes produced by British American Tobacco. ”

Lin Jiangbei nodded, which was in line with his judgment. He beckoned Xiao Zhang to bring over the four small glasses, and the four cigarette butts in them were indeed two of Hademen, and two of them were Zhongyuan.

"Principal Zhou, since this cigarette butt was not left by Captain Wang's men, then it is very likely that it was left by the murderer." Lin Jiangbei pointed to the cigarette butt on the white paper with tweezers, "Let's assume now that this cigarette butt was left by the murderer, then the image of the murderer can basically be sketched." ”

Zhou Fengshan and Wang Jiangang met each other's eyes.

It's not that they don't believe Lin Jiangbei, it's that Lin Jiangbei's statement challenges their imagination too much. As the chief of the provincial capital police department and the captain of the detective team, Zhou Fengshan and Wang Jiangang have also seen many detectives. But like Lin Jiangbei, it is the first time that he has encountered a small cigarette butt that can outline the image of the murderer.

Could it be that Lin Jiangbei is really a rare criminal investigation genius in a century, as praised by Yamada Kazutaka, director of the Tokyo Metropolitan Police Department in Japan?
