Detectives of Detective World

"Of course, no problem."

Looking at Tang Ze's hand-painted flat map, Akiko Zuo tapped the upper left corner of the map: "I remember... Mika-chan was near the gas oven at that time."

"This is the same as what we judged at the scene." Tang Ze nodded and asked, "Where are you, teacher?"

"I was standing by the kitchen door."

Akiko Sato tapped the lower left corner of the map: "My cake was ready at that time, and I was about to go out and say hello to the guests."

"Is the cake ready?"

Tang Ze was a little puzzled after hearing the words of Akiko Zuoto: "Didn't the explosion appear on the way of baking the cake?

But it can be confirmed that the fire of the explosion was indeed the oven. "

"It seems so right..." Saito Akiko said with a sigh: "It's because Mika-chan planned to use the oven to bake cakes at that time."

"I understand the situation, there are only so many things to ask." Tang Ze got up and looked at Zuo Teng Jingzi and comforted: "Please also express my condolences."

"what a shame..."

Akiko Sato couldn't help wiping her tears when she said this: "That child is better than me, and has already won the world's award... She is looking forward to receiving the award..."

"Speaking of which, Mr. Sato's award is also very impressive." Tang Ze smiled and said, "I saw it at the banquet. It is a national "grand award"."

"Compared to that kid Mika-chan, my award is nothing at all."

Akiko Sato said: "But even so, it was very precious to me, so this year when Mika-chan won the award, I deliberately took it out of the kitchen and showed it.

There is also the meaning of the guests expressing that the apprentices I have taught are "beyond the blue and are better than the blue". "

"You are really a good and dedicated teacher." Tang Ze sighed after admiring, "Have a good rest, we will leave first."

After leaving the hospital, Tang Ze took Takagi back to Kesouyan.

Although there have been deaths so far, the Metropolitan Police Department has not set up a special investigation team because it has not been confirmed whether it is a homicide case for the time being.

I just asked Ke Souyan to investigate the situation of the case and confirm whether it was a homicide or an accident before taking the next step.

And this belongs to Tang Ze's own job.

To be precise, it was the work of the "Science Research" that he led.

Under the circumstance that the situation of the case cannot be determined, conducting a scientific search provides criminals with more information to help them judge the case. This is the positioning of scientific research.

And the fact is the same. In cases where Tang Ze was not in charge, the members of Kesou Research provided assistance in this way.

As for Tang Ze's side, the criminals will instead become the tools of the investigation, not to mention the people in the research field.

Coming to the area where the forensic medicine department is located, Tang Ze and Takagi waited patiently outside after learning from the staff on duty that Ma Sheng was actually leading someone for autopsy work.

After the corpse was transported, Ma Shengji started to dissect it immediately, but after all, autopsy is a very labor-intensive thing, so Tang Ze and the two still waited for nearly an hour before they came out.

"It's hard work, let's sit over there and talk."

Seeing that Ma Shengshi led people out, Tang Ze handed everyone a bottle of coffee, and then motioned for Ma Shengshi to go to the rest table placed next to him.

"How's the situation?" After being seated, Tang Ze waited until Ma Sheng had almost finished drinking his coffee before asking.

"Let's talk about the final result first." Ma Sheng put down the coffee can and said, "The corpse was not found to be fatally injured."

"No fatal injuries?" Tang Ze was stunned when he heard the words: "Are you sure?"

"Well, there are no bones or muscles." Ma Sheng nodded.

"Doctor Aso, what does this mean?" Hearing the two of them talking like a puzzle, Takagi, who didn't understand anatomy, was at a loss.

"In short, did the explosion really only happen once?" Tang Ze couldn't help frowning when he said this.

"Eh? This question..." Takagi was stunned: "Aren't you at the scene of the criminal Tang Ze..."

"Because at the scene, I only heard an explosion, which made it seem incredible."

Tang Ze explained: "Usually, if it is a person who died because of an explosion, the victim should have serious injuries to the body under the impact of the strong explosion, which is what we usually call fatal injuries. "

"Yes, the impact generated after the explosion will cause fatal injuries to a certain vital part, but even if the fatal injury occurs, it does not mean that the impact force has completely disappeared.

The remaining impact will be transmitted to other parts of the body, but the

The deceased had no such obvious injuries. "

"In other words, did the explosion happen many times at that time?" Tang Ze pondered: "How is the situation after the dissection."

"Carbon monoxide hemoglobin was detected in the liver and heart of the deceased, which can be said to be a typical symptom that occurs after being burned to death."

Ma Shengshi said: "In addition, the lungs were also damaged, and the internal bleeding was very serious.

It can basically be determined that it is a symptom of pulmonary hemorrhage caused by the impact force generated after the explosion.

In addition, all the internal organs of the messenger have been damaged during his lifetime. "

"How is this going?"

Takagi looked puzzled after hearing the truth of Asei's words: "Why does it feel completely different from the explosion that you mentioned before?

As if that was the "point" and this one feels more average? "

"You're right." Tang Ze nodded and said, "Because the damage caused by the dust explosion is the result."

"Indeed, when I was an intern before, I followed the teacher to help dissect the victims of the pulverized coal explosion accident, and their performance was very similar to the identification results this time." Ma Shengshi said.

"Dust explosion? What is that?" Takagi asked puzzled.

This is no wonder. After all, the Internet is not particularly developed in this era. Common sense knowledge that is useless like the future generations is still a partial professional knowledge.

As for why this knowledge point is so widely known in later generations, it is because many novels that travel back to ancient times use this for the link of "pretending to be X"...

It's a routine to memorize the "black powder" formula like a traveler, but it's not so widespread...

"Take the example of the pulverized coal explosion accident."

Tang Ze said: "The working tunnel was full of coal dust, which was ignited for some reason.

Coal, which was originally a solid substance, suddenly turned into a gas due to combustion, and its volume expanded a thousand times in an instant, and then an explosion occurred.

And if there is a lot of coal dust around the explosion site, it will be continuously ignited like firecrackers, resulting in a series of explosions. "

"It is precisely because of this that even if the explosion happened in an instant, and only one explosion was heard, there were actually multiple explosions that we could not observe with the naked eye."

Ma Sheng nodded in agreement and said, "It is precisely because of this special explosion that the victim's body will be hit in multiple places in an instant."

Gu </span> "You mean, there was a dust explosion in that kitchen?"

Takagi understood what the two of them meant, and said somewhat incredulously: "But, that's the kitchen, right? There's no such thing as coal dust, right?"

"No, things like pastries will actually explode."

Tang Ze shook his head and said, "Because of this, it is called a dust explosion instead of a pulverized coal explosion.

Because pulverized coal explosion is just one type of dust explosion. "

"Wow... I feel like I won't dare to face Dim Sum in the future." Takagi shrank his neck when he heard the words.

"Don't worry, those pastries you bought have no chance of exploding."

Ma Shengshi explained with a smile: "Tang Ze said that in the process of making cakes, some powdered ingredients may explode if they are not properly handled."

"It feels even more terrifying to say that." Takagi said with shame: "There is a store of flour at home..."

"Don't be afraid, dust explosions require harsh environments. Many times, experiments are deliberately carried out, but they cannot be successful."

Tang Ze patted Takagi's shoulder and comforted: "It's basically impossible to trigger it at home normally."

"Wait, if that's the case, doesn't that mean this case..."

After Takagi heard Tang Ze's words, he suddenly reacted and said solemnly, "It's not an accident, but a deliberate murder case?"

"Although it's not completely certain, at least in this case we can't simply dismiss it as an accident and have it closed."

Tang Ze got up and looked at Ma Shengshi: "It's hard work, you can rest well, the rest is our work."

"Then what are we going to do now?" Takagi asked, "Do you want to go back to the crime scene and investigate again?"

"Let's go back today."

Tang Ze looked at Zuo Wan's watch: "It's very late, and there are traces of the fire at the crime scene, so many things can't be found.

I'll say hello to Saito Hiro later, and let him send someone with us to the crime scene tomorrow to investigate again. "

"Okay, I see." Takagi nodded and said, "Then we will meet directly at the crime scene tomorrow."

"Ok."

Tang Ze nodded, and immediately took out his mobile phone to contact Hiroshi Saito, while walking towards the underground parking lot.

After returning home, Ayako had already prepared dinner, and of course there was also a bit of grumbling.

But after all, it was the other party's concern, so Tang Ze could only be lectured by the other party obediently.

But at night, Tang Ze tried to find a way to get back to the scene, so that Ayako didn't have the strength to preach to him again.

The next morning, Tang Ze woke up early.

After getting up and taking a shower without waking Ayako, Tang Ze left a breakfast for Ayako and drove towards the crime scene.

After the explosion of the kitchen, Tang Ze found that in the empty room that had been evacuated by Kesoyan, Saito Hiro was busy on the ground.

"What are you collecting?" Tang Ze looked at Saito Hiro and asked curiously, "Have you found anything?"

"Your judgment yesterday was correct."

Saito Hiroshi kept moving his hands and said: "When I came today, I felt a little bit of granules when I stepped on it, and based on the environment, I preliminarily judged that it might be sugar.

If it was yesterday, because the ground was wet because of the water to put out the fire, it would be impossible to find it even if I came here. "

"It's just considering the possibility of putting out the fire, the investigation is put on today."

Tang Ze smiled and said, "After all, I was at the scene yesterday, and I know that the security personnel who followed up used fire hoses to put out the fire."

"With a knowledgeable boss like you, I feel a lot more relaxed." Saito Hiro smiled and continued to collect the pieces of sugar that solidified on the ground.

"Eh? Tang Ze criminals have all arrived?"

Just as the two were talking, Takagi also came with a bag. Seeing Hiroshi Saito's busy appearance, he couldn't help but wonder, "What are you collecting?"

"It's sugar."

Tang Ze replied: "Yesterday it melted because of the fire, and I didn't find it at all because of the fire, so I collected it today."

"Eh? Is there anything worth paying attention to in collecting this?" Takagi asked curiously.

"Look at the ground and the nearby walls, are there any sticky bright marks?"

Saito Hiroshi pointed to the dark surrounding walls and said, "These are all traces of the sugar that was splattered after melting, but normally, even if there is an explosion, the sugar can't be scattered that far."

"So it is." Takagi said suddenly: "So, are these important evidences that may have clues?"

"It's not just that, the entire kitchen is an important piece of evidence."

Saito Hiroshi sighed: "The thing that appraisers like us hate the most is the bombing case~www.NovelMTL.com~ because the workload is really huge.

Not only to find the fire point and the fire, but to check all the things that were blown up before you can feel at ease.

Like the residue after the burning of documents, the text on it must be restored little by little.

Although the workload is huge, the probability of getting useful information is indeed not 50%.

No, thirty is a high incense burner. "

Saito Hiroshi sighed and said, "There are also things that are not flammable, such as the trays that were sent this time, and those things should be checked all in case.

The young men under my command are still young enough to survive, but even so, they are still suffering.

But thanks to them, the evidence is almost the same. "

Saito Hiroshi looked at Tang Ze and said: "They called in the morning and said that a batch of evidence has been identified, so you have time to go over and take a look."

"I feel so tired..."

Takagi smiled embarrassedly, and seemed a little embarrassed that he was still so relaxed now: "Xin Tang Ze, do you have anything on your side to arrange for me to investigate?"

"Well... so, you and Sato Criminal go to visit the editor who had a little dispute with Saotome yesterday and ask about the situation."

Tang Ze thought for a while and said, "Although I only heard a few words yesterday, Saotome seems to have some interest connection with the deceased.

I feel like I've been able to dig up some useful information, and the two of you are taking advantage of this contact. "
