On the afternoon of the 22nd, at the first investigation meeting of the Tianjiyuan arson case, there was not much progress on the criminal investigation side, and Ying Mingyu wanted to hear the clues of the trace examination and forensic medicine first.

Because of Ouyang Jing, the meeting was postponed a little, and the criminal investigation here sorted out all the information investigated before he arrived.

"I'm sorry, it's hard to get evidence on the spot. The separation and detection of combustion aids from the ignition source may require time, and you will be notified as soon as the results are available. Ouyang Jing was concise and to the point, and the combustibles at the source of the fire were important clues for tracking down the suspects.

Ying Mingyu nodded, "Let's talk about other discoveries." ”

In the case of arson, trace inspection is very important, so Ouyang Jing came late, and he can fully understand.

"I'll start with the autopsy. Ning Duo'er was very caring, she saw that Ouyang Jing hadn't sorted out the things in her hand at all.

"The deceased, Peng Chunxiang, female, was 48 years old this year. The cause of death was suffocation caused by thick smoke, consistent with the person who died at the fire. The body was burned extensively, and there was basically no intact skin. Bone cracks were found on the forehead, the bridge of the nose, and the knees, which were new wounds, and were estimated to be caused by the deceased falling to the ground from a high altitude due to an explosion before death. ”

"Based on this, we speculate that the deceased was unaware of the fire and that the impact of the kitchen explosion pushed the deceased to a height and then fell. The fire quickly spread, and the deceased was in the fire, probably because of the head and leg injuries, and there were flames everywhere, and he could not move to escape before dying in place. Although the deceased died of suffocation in the smoke, at the same time he was burned by the fire while he was awake, and presumably died a very painful death. ”

When Ying Mingyu heard this, he felt even more disobedient, what if the murderer knew that the deceased was next to the kitchen? This would change from an arson case to an intentional homicide case.

Arson accidentally causing death is very different from arson intentional homicide, and its nature is much worse.

"The time of death is best limited from your side, and the forensic doctor's inference is between ten o'clock last night and three or four o'clock in the morning today, which is not very informative. "From the time the security guards call the police to the fire alarm to extinguish the fire and enter to save people, the time may be more accurate than what they took from the corpse.

"Understood, are there any other discoveries?" The corpse at the fire scene is difficult to test, Ying Mingyu knows it in his heart, and besides, he is not familiar with Ning Duoer, and he doesn't know what a woman's business ability is.

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

Ouyang Jing took over the conversation, "The murderer must have stepped on the point and chosen the way to invade." We've got the surveillance of the neighborhood back, and it may take some time to screen for suspicious people. Because of the fire, the exterior walls were all blackened, and the floor was affected by the heat flow, and it was difficult to make out the footprints. We speculate that the killer should have waited outside the kitchen for an opportunity to enter through the kitchen window. ”

Ying Mingyu agrees with this statement, even if there is no camera outside the door, the lock of the door also has an anti-theft alarm function, and the probability of the suspect wanting to enter from the main entrance is very low. They had checked with the property to verify the matter, and because the kitchen was in the innermost part, the door was relatively lightly damaged, and there were no signs of the locks being damaged.

After communicating with the head of the household by phone, he said that the fingerprint lock is very sensitive, and only a few people in the family are recorded, as well as the fingerprints of the company secretary. 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 the hand. Unless the prisoner and the head of the household are familiar, the possibility of entering through the main entrance is almost nil. Fang Jinshi added the findings from the criminal investigation side as evidence.

Ouyang Jing nodded and continued, "The source of the fire is in the center of the kitchen, near the gas pipe, leaving a slight distance, it should be the murderer to ensure his own safety. Later, we will simulate the ignition of combustibles in the same environment, and calculate the specific time from the fire to the explosion of the gas pipeline, so as to estimate the initial time of ignition. ”

Based on this, it is possible to reverse the time when the murderer entered the community, which is very useful for screening out suspicious characters.

"As I said earlier, we will separate and analyze the combustible substance, and we will wait for a few days. In addition, we drove around the perimeter of the complex and suspected that the killer might not have entered through the main entrance. This community is not fully enclosed, because of the large area of the area, in addition to the main entrance, side door and back door, there are several convenient entrances and exits for pedestrians only. ”

This is a new discovery, Ying Mingyu took a serious look at the picture.

"Although there is a card barrier at this entrance, the height of the entire facility is less than 1.8 meters, and if someone climbs into it, there is no alarm device. We've tried to climb in from the very side, and we've been able to get around the security cameras without triggering the alarm at all. ”

It sounds like they found a security hole in the community, and it seems that the property will have to be rectified later, and this kind of convenience facility may also be a safety hazard.

"Understood, have you brought back the surveillance in this kind of place?" It seems that in addition to the entry and exit registration records, it seems that the surveillance is inevitable.

Ouyang Jing nodded, "We will work backwards and check from the surveillance near the house where the accident occurred to see who may have been close to the house." ”

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

Bao opened his mouth, "The deceased Peng Chunxiang was a nominal housekeeping worker of a good helper housekeeping company, and he had successively engaged in housekeeping work such as nanny, housekeeping, cleaner, etc. This time, her employer is Xu Mingzhao, the owner of the house where the incident occurred, and she started working as a live-in domestic servant in Xu's family at the beginning of this month. ”

"A few days ago, Xu Mingzhao took his family on vacation and left her at home to help look after the house, which happened last night. As far as is known, the head of the household said that he has not offended anyone recently, and he is not particularly clear about Peng Chunxiang's situation. ”

It is obvious that the head of the household should not be lying, Peng Chunxiang has only been doing it for more than half a month, and he must not know each other well. However, in this case, the head of the household left the servant to watch the house alone, and seemed to be very bold, not afraid that she would run away with the money?

This question will be asked by Mingyu when he sees someone, and he won't say much for the time being.

Ning Duo'er opened her mouth 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 he had never had a grudge against anyone, at most there were two quarrels at work, and it was completely impossible to reach this level. ”

Fang Jinshi blinked, looking at the new beautiful forensic doctor.

"Well, Peng Chunxiang entered the city from the village, and he should have maintained his diligence and honesty in his early years. Most of the evaluations given to her by the housekeeping company and the reviews of her taking odd jobs were positive, so she gradually began to take on this kind of live-in nanny or domestic help. Ding Yuan and Bao Zhan went to the housekeeping company together, and added.

It sounds like no one would target such a woman, she doesn't look beautiful and eye-catching when she looks at the photos, she is nearly fifty years old, and she is down-to-earth and steady.

Could it be that this is really an arson case, and the murderer is purely a hater of the rich and a randomly selected target?

If this is the case, it is also very bad, the provincial capital is not big, and there are many high-end communities and villas, and I am afraid that the continuous arson will make people panic.

Ying Mingyu thought about these and said, "In contact with the fire department, we must strengthen fire prevention and safety knowledge education this month, and find ways to do some prevention." ”

"Boss, do you suspect that someone will set fires continuously?"

"Hopefully, I'm overwhelmed. "In any case, if they increase their efforts to promote fire knowledge, it may be able to deter the murderers.

After the meeting, Ding Yuan called, and the other party said that in addition to doing it, it was the right way to suggest that they solve the case as soon as possible.

"Ying team, tell me, how is this case characterized?" Ouyang Jing still has a lot of things, and it is better to let the criminal investigation determine the direction issue.

Ying Mingyu pondered for a moment, "Let's do it according to arson first, and then make adjustments when we understand Peng Chunxiang's social relations and find new doubts." ”

Ouyang Jing nodded and was about to dismiss the meeting, but Ning Duo'er spoke at this time, "Does Captain Ying have any instructions for our forensic doctor?"

"Hmm...... The forensic trace examination is not separated, just communicate with Ouyang more. Ying Mingyu was okay when he came to his mouth, and replaced it with the latter sentence.

Ouyang Jing's figure when he stood up paused, although he had a good temper, he occasionally wanted to punch Ying Mingyu in the face, but considering that he couldn't beat him, he still had to endure it.

"I heard that Minister Ouyang was transferred from the provincial department, why didn't he do it in the provincial department and be transferred to the city bureau, aren't you happy?" Ning Duoer immediately followed the person in front of him and accosted him.

Ying Mingyu looked at the back with a smile, and he found that this forensic doctor was a caring person, so he went to inquire about Ouyang's situation so quickly. Speaking of which, he still doesn't know why Ouyang Jing was transferred from the provincial department, and it is completely impossible for him to be delegated with his business ability.

"Hmm...... I heard that the city bureau has a good criminal police captain, and I prefer to do front-line work. Ouyang Jing looked back at Ying Mingyu as he spoke, they had a lot in common, 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 still people who came to admire him, and he was a little embarrassed.

Ning Duoer was also dumbfounded, these two men are so handsome, shouldn't there be a problem with their sexual orientation?

Zhang Ke next to him whispered a secret message to his current boss, "Minister Ouyang had a good impression of the captain's wife before, so he was blacklisted by the team." ”

Ning Duoer smiled, but she was a little curious and interested in Mingyu's wife.

After Fang Jinshi finished watching the show, he raised his eyebrows and asked Ying Mingyu, "Hey, anyway, Fan Hua is out, you lack a good friend, isn't this just right, you can't talk to that beautiful forensic doctor, right?"

"How is Fan Hua in the provincial hall? I have time to come out for a drink or two. ”

"Ying Mingyu, he said that you are cold-blooded and ruthless, and I will help you say good things, it turns out to be true, haven't you asked a word yourself?"

Ying Mingyu sighed, he was used to waiting for his friends to contact him, and he rarely took the initiative to do this. Fan Hua has been gone for so long, he really hasn't asked yet, and it was only when Fang Jinshi mentioned it that he asked casually.

"When the case is over, call him to come with you when you celebrate. He remedied it himself, and he didn't have time to make an appointment with Fan Hua for the time being.

"You shout, I don't help you pass the word, in the bureau we are purely subordinate and subordinate relations, and there is no personal relationship. ”

Ying Mingyu couldn't complain, he was worried about these parents all day long, and the group didn't even help with a word when they were together all day long.
