Ever since Zhao Xin sent a telegram back to Beihai Town, everyone knew about the murder in Fuldan City by that night; several members of the time travel group who had previously thought it was troublesome to have guards stopped talking.
Fang Hua received a telegram from Zhao Xin early in the morning, so he called his apprentice Zhang Fang, packed up some chemicals and test equipment, and took the security squad equipped for him. After crossing the river, he took a truck and went straight to Fuldan. city. Nowadays, Fang Hua is becoming more and more important to Beihai Town; it would be troublesome for others to have two guards, but Fang Hua has a squad here to protect him.
The road between the two places is not muddy. The civil affairs side has always arranged people to maintain the road and organize people to clear the snow even in winter. The journey of more than 200 kilometers took more than four hours to drive there.
Instead of going to the police station, the group went straight to the hospital, where Zhao Xin was.
Zhao Xin was not waiting for Fang Hua specifically, but was organizing people to install infrared cameras. One is installed on the top of the pillar at the entrance of each ward, and one is installed on the front and rear doors. Then the wires are connected, and the data cable is connected to a 16-channel hard disk video recorder. It's easy to tighten the screws, but Zhao Xin can only do the wiring. Now the other time and space is directly connected to the PTZ, so it’s not that troublesome at all. The question is where to get a gimbal in this day and age!
There is only one silent diesel generator in Fuldan City now. The electricity is mainly used by public institutions such as hospitals, agricultural machinery units and police stations. It is also used by large markets, so the electricity is currently a little tight. But Zhao Xin couldn't care less about it right now. Let's solve the case first and then talk about other things.
When Fang Hua and his party arrived, Zhao Xin put down what he was doing and explained the case to the other party. Fang Hua was secretly frightened after hearing this. Is Manqing going crazy?
On one side, Fang Hua began to prepare materials for fingerprint extraction. On the other side, Yonejiro followed the method described by Zhao Xin and began to extract fingerprints of all personnel within the hospital.
It is said that there are two methods for extracting fingerprints in modern criminal investigation, chemical method and physical method. The physical method is to take a box of magnetic powder and then use a fine-bristled brush to brush, sweep and sweep; of course, the more advanced method is the laser method. Chemical laws are more suitable for extracting fingerprints from physical evidence, such as murder weapons.
Fanghua uses iodine fumigation, which uses iodine crystals to heat to produce steam. In fact, this matter was not worth Fang Hua's trip. He could just explain it clearly to Zhao Xin on the radio. But Fang Hua was curious. He had done so many experiments, but he had never done evidence identification before.
In fact, since Wang Conger and her mother were sent to take care of Fang Hua's food and daily life, Fang Hua's personality gradually changed. The originally silent person also has a smile. In addition to doing experiments every day, he also goes to school to pick up Wang Conner from school. He is also amiable when talking to Wang Conner. If it weren't for these changes, Fang Hua would never have left Beihai Town and came to help.
Fang Hua first looked at the size data of the dagger, so he asked his apprentice Zhang Fang to find some pieces of glass, and then used glass glue to glue them into a glass box 60 cm long, 20 cm wide and 50 cm high; one side was made open and closed. of trap doors.
The next step is to use strong glue to attach two wires to the top of the glass box to hang the murder weapon. There will be an iron rack placed under the dagger, with an alcohol lamp below, and crystal iodine in a small beaker on the upper iron rack; a few sticks of rosin will also be prepared.
Everything is ready and the test begins. First, when burning, cover the beaker with a glass piece, wait for the iodine to quickly sublimate into purple gas, then remove the glass piece covering the beaker, and hang the dagger with colorless fingerprints on the wire.
After a thin layer of iodine is hung on the dagger, the infection is stopped, and then lighted rosin is used under the fingerprints smoked by iodine. Once a thin layer of pine cigarette smoke has adhered to the surface of the dagger, the fingerprints will be fixed. Finally, use a fine-bristled brush to gently sweep away excess pine smoke.
The preparation took more than an hour, and the fingerprint extraction was done in half an hour. The next step is to compare the fingerprints one by one, which is very laborious. Fang Hua compared five or six people and felt dizzy.
After Zhao Xin finished installing the surveillance system, he came over to watch with Fang Hua. The two of them kept seeing each other again and again at night, but the result was very bad, no one matched up!
At the same time, Yonejiro followed Zhao Xin's order and required everyone in the hospital, regardless of gender, except those who were seriously injured and unconscious, to be investigated. If anyone did not cooperate, he would be dealt with directly as a rebel and sent to Ezo to dig coal. These people are required to provide a report on their movements that night, and the report also needs to be signed by a witness.
So all the idle security police in the police station were dispatched. After a big move, everyone in the hospital participated in the investigation. During this investigation, a suspicious person was actually found.
The suspicious person is a new nurse who came here last year. She is pretty and her surname is Zhou. The main reason why she was suspected, in addition to coming here last year, was that she had no way to find anyone to prove her actions that night; and during the investigation. Yonejiro noticed that Nurse Zhou was walking with a limp, most likely because she injured her foot while escaping.
Yonejiro first interrogated Nurse Zhou himself, and at the same time sent Qihei to check Nurse Zhou's personal belongings.
During the interrogation, Nurse Zhou was so frightened that she cried and said that she was wronged. Finally, she even said that if she was really the murderer, why would she need a dagger? It would be more convenient to have a scalpel in the operating room.
After listening to Yonejiro's report, Zhao Xin raised a question: If Nurse Zhou is really the murderer, how did she secretly return to the dormitory without being discovered after escaping from the crime scene? Although she was the only one in Nurse Zhou's dormitory yesterday, flowers were planted outside the dormitory windows that could be jumped out, and there were no signs of being trampled on these flowers.
Yonejiro stammered and replied: "Sir, it seems that Nurse Zhou did not leave the dormitory last night, but what can we say about her limping?"
Zhao Xindao: "Who said that if you are limping, you must have jumped out of the window? Maybe there is something unspeakable, but it turns out that you are too fierce, and the little girl was too frightened to say anything."
Having said that, Nurse Zhou was still taken back to the police station for further interrogation.
That night, everyone in the hospital was on tenterhooks for fear of another murder, while Zhao Xin and Fang Hua sat in front of the screen and stared at the camera, closely watching the situation outside the ward.
But a whole night passed, and nothing happened, making Zhao Xin and Fang Hua's eyes red.
Fang Hua was persuaded by Zhao Xin to go back to his place to sleep. Zhao Xin found an empty dormitory in the hospital to borrow, planning to sleep for a while before getting up. But he couldn't fall asleep as he tossed and turned in bed. Thinking that if he couldn't solve the case one day, everyone would have to live another day in fear. You can only be a thief for a thousand days, but you can't guard against a thief for a thousand days. What the hell is this!
It was getting bright outside the window at this time. Zhao Xin tossed about for a long time, and finally got up and decided to go for a walk in the yard. When he led the guard to the backyard and wandered around aimlessly, he stopped at a place under the south wall.
Zhao Xin lowered his head and looked left and right at the ground in front of him, and found that there were some weeds on the surrounding ground, but there was nothing on this ground. He tried to pull the floating soil with his feet a few times, and found that the soil was actually very loose; so he continued to pull a few more times, and finally exposed the traces of a stone slab.
He had never been here before when he was inspecting the site, so he had no way of discovering anything unusual here. Zhao Xin stamped the stone slab with his foot, and when he heard the thumping sound coming from below, he knew that there was nothing under the stone slab. When he and the guard moved the stone slab away, sure enough, there was a tunnel below, but neither Zhao Xin nor the guard's burly figure could get down.
At this time, Zhao Xin already understood the reason why the murderer suddenly disappeared and could not be found; he immediately ordered the guards to find Yonejiro.
Soon, Yonejiro and Qibei arrived with several of their men. Since the entrance to this tunnel is relatively narrow, Yonejiro specially asked a thin policeman who was just 17 years old to go in to investigate.
The little policeman got in with a rope tied around his waist, a compass in his hand, and a flashlight in his mouth. After about ten minutes, the rope exposed outside the tunnel was pulled a few times, which meant that it had been It's over.
After the little policeman came out, Zhao Xin, Yonejiro and others roughly measured the length of the rope, and then sent a plainclothes officer to check around according to the direction and distance based on the compass, and finally determined a location southwest of the hospital. It is very likely that the residence is an authentic exit.
After struggling for a long time, it finally came down to on-site investigation, and it was Zhao Xin who discovered it. The ashamed Yonejiro, Saibei and others blushed with shame, and bowed to Zhao Xin to beg for forgiveness, saying in their hearts that you are still powerful and worthy of being the descendants of the emperor.
The so-called Zhao Xin is a "descendant of the Emperor of Heaven" has been vaguely circulated in Beihai Town, but everyone only talks about it in private, and no one dares to say it publicly.
Of course, Zhao Xin couldn't say that he found it accidentally, so his face showed an unfathomable look as it should have.
When things have reached this point, it seems that that residential building is very likely to be the murderer's den. The man sneaks into the hospital from the opposite side through this tunnel to commit crimes, and then sneaks away quietly.
Yonejiro immediately said that he would take people to search the opposite side, but was stopped by Zhao Xin. Zhao Xin felt that this would probably alert the snake. Secondly, if the murderer was not at home or the location was wrong, it would be troublesome for the real murderer to escape in the end. So he ordered Yonejiro to let his plainclothes men investigate secretly before arresting him.
In fact, Zhao Xin still had many concerns. He wanted to wait until Chen Jishan came back before arresting people.
Now that the Manchu spies have even obtained bullets, what if they have guns in their hands? The murderer must be very agile, otherwise he would not have slipped into the tunnel so quickly and covered it with stone slabs; but are there any of his accomplices in the hospital? Who covered the floating soil on the stone slab?
So Yonejiro left a few plainclothes men to keep watch near the residence and the south wall of the hospital, while the others returned to the police station first.
Qi Bingwei first went to the town hall of Fuldan City to investigate the household registration files. At this time, we can see the advantage of Zhao Xin asking the Civil Affairs Bureau to register population information one by one. Not only does everyone have to have their rank, name, and origin, but they also have to take photos and archive them.
Qi Bingwei quickly found out that the head of the household in that house was named Hua Er. When he came to Beihai Town, his wife was sick, and he and his two children died soon after. It wasn't until the end of last year that I married another wife. She was a one-armed woman in her early twenties, who was said to be from northern Jiangsu. When Qi Bingwei saw the photo of Hua Er's second wife, he saw that the woman was thin and small, looking frail.
When he brought the news back, Zhao Xin became more suspicious when he heard about the woman's physical features. At this time, the people sent to look for Chen Jishan had not yet received any news, so Zhao Xin ordered half of the security police in disguise to go out in disguise, stare at the house and nearby streets, and closely monitor the whereabouts of Hua Er's wife.
At the same time, he asked the town office to call the leader of the community where Hua Er's family was located to the town office for questioning in the name of promoting the new policy.
"What's the name of Hua Er's wife?"
"Sir, I heard that her surname is Su. As for her maiden name, it's hard for us to find out."
"Well, what happened to her one arm? Which arm is missing?"
"The left forearm is missing. I heard from Hua Er that it was crushed by a bullock cart in the village when he was a child." When the team leader said this, he couldn't help but frown.
As soon as Zhao Xin saw it, he immediately asked: "Is there something wrong?"
The resident group leader said rather embarrassedly: "Sir, I went to the bathhouse to take a bath one day, and I bumped into the Hua Er family. When she came back, she told me that the Hua Er family had bad arms. It looks like it was crushed, but it looks like it was chopped with a knife."
Yonejiro on the side immediately raised his head after hearing this, and heard Zhao Xin ask the resident group leader: "Are you sure?"
"Sir, I used to be a butcher in my family. She also killed pigs before she married me."
Zhao Xin nodded and signaled that the leader of the residents' group could leave, and Yonejiro followed him out to explain. When he returned to the room, he said excitedly: "Sir, what do you think?"
Zhao Xin slammed the table: "She's not running away! It's her!"
In the afternoon, Chen Jishan finally led the team back. Two Qing spies who escaped caught one and shot one to death. The missing bridge clip and more than 20 rounds of bullets were found on the body of the guy who was killed; the guy who was captured was also seriously injured and was sent to the hospital for emergency treatment because he had not yet asked for a confession.
Looking at Chen Jishan who looked tired, Zhao Xin patted him on the shoulder to encourage him, and then asked: "Jishan, can you go and catch someone again?"
Chen Jishan habitually cupped his hands and said, "I'm not tired. Please tell me, sir, who are you going to arrest?"
"murderer!"
With a company of troops and a large number of security police dispatched, the streets and alleys around Hua'er's house have been cordoned off. Chen Jishan, Qi Bingwei and several gun-wielding soldiers knocked on Hua Er's door.
It was Hua Er's daughter who opened the door. As soon as the eight-year-old girl opened the door, she was frightened by a group of people wearing military and police uniforms in front of her. Hua Er, who was eating in the house, heard the sound and came out to check the situation. When he saw a group of soldiers standing at the door, his face suddenly turned pale, and he lost his grip on the bowl and dropped it to the ground.
"Hua Er, where is your wife?" As soon as Qi Bingwei finished speaking, he heard a shout from behind the house.
"stop!"
"Someone ran away from the room!"
Several shouts came from the back of the house. Chen Jishan's expression changed as he stood at the door. He raised his head and jumped up, hooked his hands on the eaves and struggled with his arms before getting on the roof. However, Qi Bingwei and others only felt their eyes blur. When they looked up again, they saw Chen Jishan squatting on the roof.
At this time, Chen Jishan quickly climbed to the roof and saw a thin figure running wildly on the roof. At this time, he had jumped onto the house of a family in the south.
Chen Jishan took a deep breath and jumped onto the opposite roof in a few short steps. Then he saw that the man had jumped off the roof, turned left along the alley, and ran towards the big market. Chen Jishan hesitated for a moment, then jumped off the roof and rushed through the alley on the other side.
If a person is missing an arm, no matter how hard he trains, his power when running will always be lower than that of a normal person. When the woman was two alleys away from the big market, she heard a "swish" sound coming from the alley, as if a handful of dirt had been sprinkled on the ground.
Immediately afterwards, the thin Chen Jishan came out, his face was not red and he was not out of breath. He looked at the murderer in front of him and smiled: "I didn't expect that you are actually a practitioner! Judging from your career, you have been a snitch before. ?”
