On the afternoon of the 22nd, the first investigation meeting of the Tianjiyuan arson case was held. The criminal investigation was not progressing much, and Ying Mingyu wanted to listen to clues about the trace examination and forensic doctors first.

Because of Ouyang Jing, the meeting time was postponed a little, and the criminal investigation team organized all the investigation information before he arrived.

"Sorry, it's difficult to collect evidence on site. It may take some time to separate and detect ignition aids from the ignition source. I will tell you the first time if there is a result." Ouyang Jing said concisely. The ignition aids from the ignition source are an important clue to tracking down the suspects.

Ying Mingyu nodded, "Tell me and see what other discoveries are."

Trace inspection is very important for arson case, so Ouyang Jing came late and he could fully understand.

"Let me talk about the autopsy first." Ning Duoer was very considerate. She saw that Ouyang Jing had not sorted out the things in her hands at all.

"The deceased Peng Chunxiang, a woman, is 48 years old this year. The cause of death was suffocating death caused by thick smoke, which is consistent with the person who died in the fire. A large-scale burn was damaged and basically had no intact skin. Bone cracks were found on the forehead, nose bridge, and knees. It was a new wound. It was estimated that the deceased had exploded before his death and fell to the ground from a high altitude."

"Based on this, we speculate that the deceased did not notice it after the fire broke out. The impact of the kitchen explosion pushed the deceased to a high place and then fell. The fire spread quickly. The deceased was in the fire. It may be because of the impact of the head and legs, and the fire was everywhere, so he could not move and escape. Although the deceased died of suffocation from thick smoke, he was also burned by the fire when he was awake, and he must have died in great pain."

Ying Mingyu felt even more incongruous when he heard this. What if the murderer knew that the deceased was next to the kitchen? This would have changed from arson to a intentional homicide.

Accidental death caused by arson is very different from intentional homicide, and it is much worse in nature.

"It is best to limit the time of death from you. The forensic doctor inferred that it was between 10 o'clock last night and 3 or 4 o'clock today, and there was no reference." The security guard called the police to come to the fire to put out the fire and enter the scene to save people. The time may be more accurate than what they obtained from the corpse.

"I understand, are there any other discoveries?" Ying Mingyu knew that the body in the fire was difficult to verify. Besides, he was not familiar with Ning Duoer and didn't know how good a woman's business ability was.

Ning Duoer shook her head, "I'll help you re-examine it in two days."

Ouyang Jing took over the topic, "The murderer must have stepped on some points and selected the invasion method. We took back the surveillance of the community and may take some time to identify suspicious people. Because of the fire, the exterior walls were all blackened, and the ground was affected by the heat flow and it was difficult to identify footprints. According to our speculation, the murderer should have been waiting outside the kitchen for an opportunity and entered through the kitchen window."

Ying Mingyu agreed with this statement. Even if the villa houses in high-end communities do not have cameras outside the door, the door locks have anti-theft alarm function. The probability of suspects entering from the main door is very low. They have checked the property to verify this, and because the kitchen is at the innermost point, the door is damaged relatively lightly, and no traces of their locks being damaged were found.

"When communicating with the head of the household, he said that the fingerprint lock is very sensitive, and only a few people in the family and the fingerprints of the company secretary were entered. As for the door card and password, because it is rarely used, the door card is locked in the study cabinet, and the password is only recorded in the memo in hand. Unless the prisoner and the head of the household are very familiar with it, the possibility of entering from the main entrance is almost zero." Fang Jinshi added the discovery on the criminal investigation side as evidence.

Ouyang Jing nodded and continued, "The source of the fire is close to the gas pipeline in the center of the kitchen, and it is a little distance. It should be the murderer to ensure his own safety. Later, we will simulate the ignition of the ignition material under the same environment, calculate the specific time when the gas pipeline will explode after the fire, and speculate the initial time of the ignition."

Based on this, the time when the murderer enters the community can be reversed, which is very useful for screening suspicious characters.

"I just said that we will separate and analyze what kind of combustible substances are. We will wait a few days. In addition, we drove around the periphery of the community and suspected that the murderer might not have entered through the main entrance. This community is not completely closed. Because of its large area, in addition to the side door and the back door of the main entrance, there are several convenient entrances and exits only for pedestrians."

This is a new discovery, Ying Mingyu looked at the picture carefully.

"Although there are card swiping obstacles in this kind of entrance and exit, the entire facility is less than 1.8 meters tall. If someone climbs in from the side, there is no alarm device. We have tried to climb in from the side, and there is no alarm at all, and we can bypass the surveillance camera."

It sounds like they discovered security loopholes in the community. It seems that the property management needs to be rectified in the future, and such convenient facilities may also be a safety hazard.

"I understand, have you taken back the surveillance in such places?" It seems that in addition to the entry and exit registration records, it seems that it is inevitable to look at the surveillance.

Ouyang Jing nodded, "We will turn it back and check it out from the surveillance near the house where the accident happened to see who may have been close to the house."

Ying Mingyu didn't want to express his opinion on his way of doing things, "Let's talk about the situation of the deceased."

Bao opened his mouth and said, "The deceased Peng Chunxiang is a famous housekeeping staff member of the Good Help Housekeeping Company. She has worked in housekeeping such as nannies, housekeeping, cleaners, etc. This time her employer is Xu Mingzhao, the owner of the house where the incident happened. She worked as a servant in the Xu family, which started at the beginning of this month."

"A few days ago, Xu Mingzhao took her family on vacation and kept her at home to help see the house. What happened last night happened. As far as we know, the owner of the household said that he had not offended anyone recently and was not particularly clear about Peng Chunxiang's situation."

It is obvious that the head of the household should not have lie. Peng Chunxiang has only been doing it for more than half a month and must have had a deep understanding of each other. However, in this case, the head of the household stayed to help the servant who was alone to keep the house. He seemed to be very brave. Aren’t she afraid that she would run away with the money?

When Ying Mingyu saw this question, he would ask him, but he didn't say much for the time being.

Ning Duoer spoke at this time, "When the deceased's son and daughter-in-law came to sign, I asked a few questions. They said that the deceased was simple by nature and had never made any complaints with anyone. At most, there were two quarrels at work, and it was completely impossible to reach this level."

Fang Jinshi blinked and looked at the new beautiful forensic doctor.

"Well, Peng Chunxiang came to the city from the village and should have maintained her hard work and honesty in her early years. Most of the evaluations given to her by the housekeeping company and the evaluations she received odd jobs at home were well received, so she gradually began to take on such jobs as nanny or servants." The housekeeping company where Ding Yuan and Bao Zhan went to add.

No one sounds like this woman. She looks pretty and charming when looking at the photos. She is nearly fifty years old and is down-to-earth and steady.

Could it be that this is really an arson case, and the murderer is purely due to the affair with the rich, so he chose the target at will?

If this is the case, it will be bad. The provincial capital said it is big or not, and there are many high-end communities and villas. I am afraid that continuous arson will cause panic.

After thinking about this, Ying Mingyu said, "In contact with the firefighter, we must strengthen the education on fire prevention and safety knowledge this month, and also find ways to prevent it."

"Boss, do you suspect someone will set fire continuously?" Dazhuang came quickly.

"I hope it's because I'm worried." In any case, if they increase their efforts to promote fire protection knowledge, it may be able to deter the murderers.

After the meeting, Ding Yuan called, and the other party said that he would do it, and suggested that they solve the case as soon as possible.

"Captain Ying, tell me, how is the case currently determined?" Ouyang Jing still has many things, so it is better to make the criminal investigation issue settle the direction.

Ying Mingyu thought for a moment, "First follow the arson, and then make adjustments when we have learned about Peng Chunxiang's social relations and find new doubts."

Ouyang Jing nodded and was about to end the meeting. Ning Duoer said at this time, "Captain Ying has any instructions to our forensic doctor?"

"Well... Forensics will not be separated from each other, just communicate more with Ouyang." Ying Mingyu's words were fine, but it was changed to the following sentence.

Ouyang Jing paused when he stood up. Although he had a good temper, he occasionally wanted to punch Ying Mingyu in the face. Considering that he couldn't beat him, he had to endure it.

"I heard that Minister Ouyang was transferred from the provincial department, so why don't he be transferred to the municipal bureau when he is not in the provincial department? Are you unhappy?" Ning Duoer immediately followed the person in front and asked questions.

Ying Mingyu looked behind with a smile. He found that the forensic doctor was a scheming person and went to inquire about Ouyang so quickly. He still doesn't know why Ouyang Jing was transferred from the provincial department. With his business ability, it is impossible for him to be deported.

"Well... I heard that the Municipal Bureau has a very good criminal police captain. I prefer to do front-line work." Ouyang Jing turned around and looked at Ying Mingyu. They had a lot of common ground, but unfortunately some people completely regarded him as an enemy rather than a brother.

Ying Mingyu was stunned. He didn't expect that there were people who came here to admire his name, and he admired his name. He was a little embarrassed.

Ning Duoer was also stunned. Both men are so handsome, so there is no sexual problem, right?

Zhang Ke from beside him whispered a secret message to his current boss, "Minister Ouyang had a little fond of his wife, so he was put on the blacklist by the team."

Ning Duoer laughed, which corresponds to Ming Yu's wife having a little curiosity and interest.

After watching the show, Fang Jinshi raised his eyebrows and asked Ying Mingyu, "Hey, Fan Hua is out anyway. You are missing a good friend. This is not the right thing to do. You can't talk to that beautiful forensic doctor, right?"

"How about Fan Hua in the Provincial Department? If you have time, make an appointment to have two drinks."

"Ying Mingyu, he said you are cold-blooded and ruthless, and I also said good things to you. It turns out that it is true. Have you never asked a question yourself?"

Ying Mingyu sighed. He was used to waiting for his friends to contact him. He rarely took the initiative to do this. Fan Hua had been away for so long, and he had never asked. This was what Fang Jinshi mentioned, so he asked casually.

"When the case is over, call him to come together when celebrating the merits." He made up for it himself, and had no time to make an appointment with Fan Hua for the time being.

"You shout, I won't help you pass the message. In the bureau, we are purely superior and subordinate, and we have no personal relationships."

Ying Mingyu was powerless to complain. The one in his family was worried about these family issues all day long, and the one in the group was together all day long and didn't even help him with words.
