"Lure Xiang Jun with police flowers again?" I asked right away.

"No, it's a more perfect plan, if Xiang Jun is really the murderer, this plan is easier for him to use!" Liu Jin seems to be very confident.

"What's the plan?" I'm curious.

"Tonight. We'd go to the East Gate woods, dig the pit again, and post announcements all over the school. The content of the announcement is that a male skeleton was found in the woods of the East Gate, and after identification, the time of his death was more than 20 years. ”

Hearing about this plan, I was a little worried. Following the rape and murder case, another skeleton was dug up in the woods of the East Gate, and this incident was suddenly poked out, will it cause panic among teachers and students? The most important thing is that now that Wang Ze's body has been burned, there is no basis for this matter, and the school will be unhappy.

"You can rest assured, this plan has been approved by the director, and our director will come forward to tell the school leaders that this is a smoke bomb set off to solve the rape and murder case. As long as the case is solved at that time, the impact of the rape and murder case will be eliminated. It's too late for the school to rejoice! "It seems that Liu Jin and they have already taken this factor into account.

"Posting announcements should be just a small part of the plan, right? I asked again.

"There are only seven people who have worked in the school's security department for more than 20 years, and tomorrow we will talk to them next to each other, do a basic survey, and ask them if they have any impressions of this matter. Of course, it has been so long, and we did not expect any valuable information from this interview, the main purpose of which was to see how Xiang Jun reacted. Two days after the announcement is posted, that is, in the afternoon of the day after tomorrow, we will ask the seven security guards again. ”

"Ask again?" I interjected in confusion.

"Yes, this time the question is very important! We will take the opportunity to tell them something, and after the announcement was posted, a veteran employee of the school provided clues to the police that he happened to see the murder in the East Gate Grove more than 20 years ago. The murderer was a man in his twenties, he didn't dare to call the police out of fear and the idea that more things are better than less, so many years have been a little uneasy in conscience, a few years ago his wife was terminally ill and died, and his children didn't care much about him, he felt that this was God's retribution for him, and now that this matter has seen the light of day, he decided to stand up and testify. ”

When Liu Jin said this, I was also thinking about it, and when he finished speaking, I thought of an unreasonable place, so I said: "If the murderer of the two cases is really Xiang Jun, then he should have disguised his appearance when he committed the crime." Either the light is too dim to see him clearly, otherwise, there is no way to explain why he can still calmly work at school after being bumped into him by Chen Feng and committing violence. ”

"It's easy to explain, more than 20 years ago, the number of students in the school was small, and the east gate was several times more secluded than now, Xiang Jun shouldn't have thought that there were other people besides Wang Ze, in fact, there was really none, this was all designed by us. We will tell the seven security guards, at that time, the witnesses hid behind the trees and saw the whole process, so they had some impressions of the murderer's face, and we used this information to make Xiang Jun's heart panic.

As for the recent rape and murder case, Chen Feng's diary has already said that he is timid by nature, and his student ID card fell in the woods again, he only thought it was rape and not rape and murder at the time, and he was worried that the murderer would kill him if he could not sentence him to death after calling the police, so he did not dare to call the police. Xiang Jun should have been disguised when he committed the crime, and he picked up Chen Feng's student ID, so he had no fear. Again, after the incident, it is not easy for him to continue to work normally to arouse the suspicion of the police, and absconding in fear of crime is a dead end. Liu Jin explained my doubts.

I pondered it for a while, and felt that there was some truth, so I asked Liu Jin to continue to talk about their plan.

"When revealing this news, we designed two important information, according to our restoration of the incident, Xiang Jun first raped Mi Jia's mother, and then killed Wang Ze, and Mi Jia's mother did not die, then, when Xiang Jun killed Wang Ze, she was likely to watch from the sidelines, which is also the reason why she was extremely afraid of Xiang Jun.

The announcement only said that we had found a male skeleton, and Xiang Jun was sure that we would not be able to get any valuable information from the skeleton, and that even if I told him that there were eyewitnesses, he would have been lucky. However, if we say that the witness saw a woman standing next to him, it shows that the witness did see the whole process, and this will put pressure on Xiang Jun's heart.

The second piece of information in the design is that we found Xiang Jun's work photos in the Security Section, and asked the technicians to depict the general appearance of the murderer according to Xiang Jun's appearance more than 20 years ago.

We will show this portrait of the murderer to Xiang Jun and the others, and say that it is based on the appearance of the murderer that the witness saw that night. Now more than 20 years have passed, and most of Xiang Jun's six colleagues can't remember what he looked like back then, but if Xiang Jun himself saw the portrait, his mind would be different! Hum! ”

"The disclosure of these two pieces of information will definitely have a great impact on Xiang Jun's psychological defense line." I also think Liu Jin's plan is feasible.

Liu Jin paused for a moment and continued: "Yes, so this time we are bound to win!" Of course, this can also be said to be a gamble, because this plan is completely based on conjecture, Brother Hao and I both agree with your speculation, and first set Xiang Jun as the murderer, so we had this plan. In fact, this is not in line with the formal case-handling process, but Brother Hao really wants to solve this case so much, it can be regarded as using extraordinary means! ”

Liu Jin's words made me very worried, if Xiang Jun was not the murderer in the end, then I would be guilty. But I thought about it for a while, their plan did not directly point the finger at Xiang Jun, but let Xiang Jun's heart change, and he showed his feet, if he was not a murderer and did not show his flaws, he would naturally not have any bad impact on him. When I think about it this way, I feel much more at ease.

"What flaws do you want him to show?" I then asked.

"When we show them the portraits, we will say that although the murderers of the crime back then may be both outside the school and inside the school, but it is obviously unrealistic to investigate people outside the school, we will start with the people in the school, collect all the photos of the male workers between the ages of 40 and 50 when they were young, and compare them with the portraits one by one, if there is still no result, we will ask witnesses to identify them in person, so that if they can't be found, the case will end here, and it will be listed as an unsolved case."

"The investigation method you mentioned is a bit inappropriate, even if the murderer was a person in the school, in his twenties, it is very likely that he was a student in the school, but those students have already graduated and left, how can they investigate?" I smacked my lips.

"Haha, of course this method is not suitable, in fact, it is impossible for the public security organs to handle this when this situation is encountered. However, it sounds like this method is full of loopholes, but it is different for Xiang Jun, with the foreshadowing above, Xiang Jun heard this method again, and his psychology was further impacted, and he was unwilling to let the investigation of the case go to the step of face-to-face identification, and in a panic, he may do something like a dog jumping off the wall! ”

"What's the matter?" I asked.

"Kill the witness!"

"Would he do such a non-confessional thing at this critical time?" I'm a little puzzled. Die as much as you can.

"If we ask him what he's doing too obviously, of course he won't. When we ask seven security guards, we will give them the same information and ask them the same questions. In the process of questioning, we will also be quite polite, sometimes asking about business, sometimes chatting with them, and in the middle of the questioning, we will go out to smoke and go to the toilet or something. And during our absence, we would deliberately leave all the information in the room to give them the opportunity to look at the basic information of the witness, which included the witness's address. Liu Jin said with a smile, it seems that they have considered every issue I am worried about.

After listening to him, I understood that even if Xiang Jun secretly saw the information of the witnesses, he would take it for granted that even if the police suspected it afterwards, the other six people were also suspicious, and with his means of eliminating evidence and his strong psychological element, he was sure that as long as he was well prepared, he could rule out his suspicion. In order not to expose the events of many years ago, he would take risks and kill people according to the address on the information, while Liu Jin and the others only needed to ambush in the "witness's" room in advance and wait for the rabbit.

"It's a perfect plan." After listening to it, I sincerely admired it. Liu Jin and Yang Hao are police officers after all, they can understand the psychology of the suspect and have a target, if it were me, even if I wanted to do it all day, I might not be able to come up with this plan.

"Haha, this is something that Brother Hao and I came up with after suffocating a lot of brain cells, can it be perfect. In addition, we are also going to rent a house opposite the military house to monitor him so that we can keep track of his movements. In this deployment, two-thirds of the police force in the station will participate, and Brother Hao can be regarded as out of the way. ”

"I hope to find out the truth of both cases in one fell swoop!" I followed his words.

"Definitely! Anyway, the announcement is printed, we have to go out and start posting it, and you can see it when you come to school tomorrow morning. After Liu Jin finished speaking, he hung up the phone.
