My spy diary

Chapter 461 Investigation (Part )

The M24 hand grenade was finalized in 1924. It has a long handle design and a large TNT charge, so it has a strong explosive power, a long throwing distance, high accuracy, and good balance performance.

After China introduced the production technology of this grenade, due to technical limitations, the stamped steel plate shrapnel of the M24 grenade was changed to cast iron, and the wooden handle was shortened, reducing the size and weight to suit Chinese soldiers. This imitation grenade caused heavy casualties to the Japanese army on the front line.

As far as Zhang Yi knows, this type of grenade is currently produced by the Gongxian Arsenal and directly equipped to the German-equipped divisions. How could it fall into the hands of Japanese spies?
Stealing or reselling arms? Or was it someone from within the German-equipped division who did this?

Zhang Yi's expression became serious and he immediately informed He Zhiyuan.

"what's the situation?"

He Zhiyuan turned around in surprise, but when he took the fuse fragment from Zhang Yi, his face darkened:
"German grenades?"

If the grenades were stolen or resold, that would be fine, just arrest a few people to serve as a warning to others, but if someone from within the German-equipped division was involved, then the matter would be serious.

He Zhiyuan frowned, a little upset: "The ones that can be called German-equipped divisions are the 3rd, 6th, 9th, 14th, 36th, 87th, 88th and the Training Corps. Most of these troops are on the front line."

Zhang Yi reminded: "There is also a tax police corps."

Although the Tax Police Corps does not belong to the regular army, it was reorganized into a teaching division according to the order of the Military Commission and is also equipped with German equipment.

More importantly, this force is somewhat special. It was set up by Boss Dai with the assistance of Minister Song’s younger brother Song Ziliang, and is jointly led by the Ministry of Finance and the Military Control Commission.

Hearing what Zhang Yi said, He Zhiyuan frowned even more.

"Maybe things are not as bad as we thought, and the grenade may have been bought on the black market."

"I hope so!" He Zhiyuan raised his hand and rubbed his temple, sighed, and was about to say something when he heard a plainclothes officer shout, "Corpse!"

Zhang Yi and the other man walked over immediately and saw a disfigured corpse curled up near the wall.

"Forensic doctor."

A forensic doctor wearing a captain's uniform and carrying an autopsy box immediately came up, put on gloves, and began the autopsy.

All the people standing nearby, including Zhang Yi and He Zhiyuan, watched his every move intently.

The forensic doctor first opened the dead man's mouth, which was surprisingly clean. He thought for a moment and began to carefully caress his body from head to toe.

After observing carefully for a while, he took a scalpel, cut a knife into the charred corpse's chest, fumbled for a moment, then smiled knowingly, stood up, walked up to He Zhiyuan and said:

"Director He, that's about it."

"Go ahead."

"Yes. There was no foreign matter in the body's mouth, which means he was dead before the explosion and fire. He had only one fatal wound on his body, on his chest, or more precisely, on his heart. The attack came from the back, killing him with one blow."

He Zhiyuan's eyes were bright. "Killed with one blow, without any struggle? If he was a guard, he wouldn't have just sat there and waited for death. This means he knew the murderer and was probably an accomplice, or he was the traitor. Is that correct?"

The forensic doctor thought for a moment and said, "It's possible. The other bodies were all outside the explosion, and this one was the only one in the center. It's very suspicious, but the body was severely damaged. There are no signs of struggle on the wrists and neck. As for whether he is an accomplice or a traitor, further verification is needed."

He Zhiyuan nodded, then looked at Zhang Yi: "Brother, what do you think?"

"It's hard to say." Zhang Yi pondered and asked, "How many guards are there? Does the number of corpses match?"

"Seven people, plus the body in front of us, the number is exactly right."

"So." Zhang Yi's brain was working quickly, and he asked, "Did you find any traces of watches or other timing devices?"

Combined with the current clues, Zhang Yi believes that the murderer must have escaped before the explosion, so he must have used a time bomb. In this case, in addition to explosives and detonators, he must have a timing device. If he deliberately buys an electronic timer or electronic components, there will definitely be more clues. In order to avoid leaving any clues, the most common way is to modify it with a watch.

"Not yet." A plainclothes officer said in annoyance.

"Then why are you still standing there? Keep searching. Even if you have to use a sieve, you must sift it out for me." After saying this, He Zhiyuan took the magnifying glass and tweezers and went to investigate. He was even more serious than any of his subordinates.

With the leader saying so, what else could the others say? Everyone took a flashlight and tweezers and began to carefully pick out the traces of the explosion covered in smoke and fire.

Hard work pays off. A few hours later, a plainclothes officer exclaimed happily, "I found it!"

"sure?"

"Look, isn't this the back cover of a watch? Could I be mistaken?" The plainclothes officer held a dirty piece of film with a smug look on his face.

"Great." He Zhiyuan was overjoyed, he didn't expect his luck to be so good. Although the explosion center was so large, the remains of the watch or timing device were so small that finding them would be like looking for a needle in a haystack. He immediately walked over to check.

He took the thin piece and examined it carefully for a while, and finally confirmed that it was indeed the bottom cover of the watch. His expression finally relaxed and he said:

"Brother Yunyi, it seems that your guess is correct."

Zhang Yi nodded. In this way, he could make a criminal psychological profile based on the clues currently available.

He paused for a moment, looked around, and analyzed: "The murderer was well-trained, his method was clean and neat, and he left very few traces of the crime. There is no witness or physical evidence at the moment, and we know nothing about the murderer's age, gender, or physical characteristics.

But judging from the guard's experience, I tend to believe that the murderer is a man. Judging from the fact that he escaped successfully later, he is very familiar with the environment near the warehouse. He either works or lives nearby, or has visited the area in advance.

So, we are looking for a strong man who works or lives nearby, who is likely to have military training, who can install bombs, who is single and lives alone. We need to be patient and check every household. If we find someone who meets the requirements, we should not alert the enemy and keep him under surveillance first.

In addition, we can start with the guards and visit their families and neighbors to see if they have any unusual behavior recently, or if they have interacted with strangers. By cross-checking, we will definitely find this person. "

"Yes." A group of plainclothes officers from the Operations Department answered in unison due to Zhang Yi's identity, but it was clear from their expressions that they were all a little confused.

He Zhiyuan nodded secretly, and couldn't help but admire Zhang Yi's professional skills. He was able to draw a portrait of the suspect just by looking at the scene. This was not a skill that could be acquired overnight. No wonder he was able to catch spies so many times.

Seeing the confused and stupid looks on his men's faces, he was furious. He thought, how could the gap between people be so big? He immediately scolded:

"If you don't understand anything, ask immediately. Don't pretend to know. If anyone makes a mistake later, I'll make him pay for it!"

After hearing what he said, a plainclothes officer hurriedly asked cautiously, "Director Zhang, how did you know that he had military experience, was single, and lived alone?"

Zhang Yi did not answer him, but looked at He Zhiyuan.

After all, he is no longer in the Operations Department, so he does not need to be in the limelight. As a subordinate, no matter how urgent the situation is or how difficult the problem is, you may have been the one who cut through the thorns and brambles for ninety-nine steps, but when you finally reach the finish line, you must not compete for the credit, and the superior leader must complete the finishing touch.

Otherwise, wouldn't it seem that you are smarter and more capable than your leader?
So Zhang Yi smiled and said, "That depends on your chief. He is the expert. I learned all these little tricks from him."

He Zhiyuan pondered for a moment, stared at the plainclothes officer who was asking the question and said, "I remember you were from the Linli training class, right? It seems you didn't study seriously. Humph, do you still need to ask such a question? Using a watch to make a time bomb is a common method used by agents and the military. I remember it was mentioned in your training materials.

Next question, doesn't a person who needs to make a bomb need a separate house? Speaking of being single, do you think it is easy for a man with a family to make a bomb without being discovered by his family? "

It turned out to be so, and everyone suddenly realized.

"Did you hear that? Director He is really meticulous and has foresight!" Zhang Yi exclaimed in admiration.

As soon as He Zhiyuan's thoughts were opened, he immediately became excited: "In addition, the source of grenades and explosives cannot be ignored. First, check the black market to see if anyone has inquired about or purchased them recently. Anyone who is suspicious should be monitored immediately. With this two-pronged approach, there is no need to worry about not being able to dig out this hidden spy, huh?"

"Yes." As soon as these words were spoken, the plainclothes police officers were immediately excited. It turned out that the old ones were the wisest. The director was worthy of being the director. He was experienced and he found the clue to a murder case with no witnesses or physical evidence so quickly.

Once you have a clear idea, your subsequent work will have a direction.

As long as we investigate step by step, it is only a matter of time before we catch the spy.

Just when everyone was full of confidence that they had a direction, He Zhiyuan's secretary suddenly walked over, looking as if he wanted to say something but hesitated. He walked over and whispered a few words to the secretary, and when he walked back, his expression was a little gloomy.

He was silent for a moment, and finally said, "The Telecommunications Department has found the location of the Japanese spy radio station, but the building is empty and the top-secret documents may have been passed on. The director is furious."

Zhang Yi pursed his lips and said nothing.

He is a leader after all, and he cannot let others notice his anxiety.

Everyone was silent.

He Zhiyuan coughed lightly and said, "No matter what, we must hurry up and dig out the murderer of the bombing and the spy network behind it.

First, Team Leader Liu, you will be responsible for making arrangements and continuing to screen the explosion site. All the remains at the site should be handed over to the technical department for analysis and identification to see if more clues can be found.

Second, Team Leader Ma, you need to arrange some people to carefully survey the area around the warehouse and visit residents to see if there have been any suspicious vehicles or people nearby some time before the incident.

Third, Team Leader Zhang, you are responsible for arranging personnel to obtain detailed statements from the family members of the guards, the warehouse manager, and all their colleagues and friends. You must list their complete social relationships and investigate whether anyone in these social relationships has behaved abnormally.

Fourth, Team Leader Yang, you organize plainclothes officers, informants and gang members to conduct a survey of the black market to see if there has been any arms deal recently.

Fifth, Captain Hu, in addition to the special forces brigade, you should directly select some experienced patrol officers and household registration police from various jurisdictions of the police station, and visit nearby residential areas in detail, checking every household to see if there are any suspicious elements.

Okay, let's start with physical evidence, witness testimony, social relations, and the black market. Mobilize everyone and go all out to solve this case as soon as possible!"

"Yes."

After arranging the task, Zhang Yi and He Zhiyuan rushed back to the bureau headquarters without caring about their fatigue.

In the office, Dai Chunfeng was seen sitting gloomily on the sofa, while Mao Qiwu was standing beside him with his head lowered.

Without letting the two sit down, Dai Chunfeng asked directly: "How is the investigation going?"

He Zhiyuan reported the situation truthfully. Dai Chunfeng listened without making any comment but just snorted a few times.

He Zhiyuan couldn't figure out his attitude, so he asked carefully, "Officer, has something happened?"

Dai Chunfeng snorted coldly: "You two, this matter is a bit troublesome. First there was an explosion, and then confidential documents were stolen within one day. The nature of this is extremely bad. Not only is the old man furious, but there are also some villains fanning the flames behind the scenes, saying that our military control is incompetent."

"A villain fanning the flames?"

Dai Chunfeng didn't say anything, but gave him a positive answer with his eyes.

"That's right." Mao Qiwu continued, "Apart from the bastard from the Central Bureau of Investigation and Chen Tumu, who else could it be?"

"Xu Zengen?" He Zhiyuan sneered, "What does the case of Japanese spies have to do with the Central Bureau of Investigation? Does he want to interfere in the case?"

"Xu naturally doesn't have the courage, but I'm not sure about Chen Tumu."

He Zhiyuan quickly asked: "Director, then, how should we investigate next?"

Dai Chunfeng thought for a moment and said, "You decide."

"Ah, I'll take care of it?" He Zhiyuan looked stunned.

Dai Chunfeng smiled grimly: "You can continue to investigate as you should, but you must preserve all the evidence and clues you have collected so far. I will tell you the specific details after I come back from the meeting."

"What kind of meeting?"

"It's mainly about accountability and aftermath. The old man is very worried about the attitude of the Americans. He will hold an emergency meeting at dawn. I will be there soon. Maybe. Maybe we won't have to investigate this case after I come back."

"That"

Dai Chunfeng interrupted him, his expression extremely serious: "Continue to investigate the relevant clues, but the current situation must not be disclosed to anyone. Just investigate on your own, the more detailed the better, but you must not disclose what you find to other people, including irrelevant people in the bureau. If I come back, the bureau will no longer lead the case. How to transfer the clues at that time will be up to my arrangement. Do you understand what I mean?"

He Zhiyuan understood what he meant and said sternly, "I understand, Chief."

Zhang Yi also quickly said, "Yes."

Zhang Yi understood immediately after Dai Chunfeng said this. He was worried that the case would no longer be led by the Military Intelligence Bureau. If there was a new person in charge, he would have to investigate the case from beginning to end and get a comprehensive understanding of the case and all the evidence and clues. If the clues they analyzed and grasped today fell into the hands of the new person in charge, and he solved the case as soon as he took over, wouldn't Dai Chunfeng lose face? How could the Military Intelligence Bureau still have the face to survive?
