"The knot of the rope is located directly behind the head, and the other rope is tied to the knot of the first rope."
Aso Minoru had already taken out the contact lens from the deceased's eye, looked at Karasawa and asked: "Are you very concerned about the rope?"
"Of course, this rope can strangle someone with just one rope. I don't understand why we need to tie another rope at the knot." Tang Ze nodded.
"Maybe the rope had other uses, but the murderer picked it up casually when he committed the crime."
After Aso confirmed his guess, he immediately said: "Get the rope and look at the marks."
"This is also a possibility."
Tangze took off the rope and couldn't help frowning after looking at the strangulation marks: "This strangulation mark is diagonal."
"suicide?"
Looking at the bruises that circled upward diagonally, Aso Minoru also had a look of confusion on his face: "Generally speaking, if it is a homicide, that is, someone strangled to death, the strangulation marks should be parallel to the head."
"Here's the weird thing."
Karasawa pointed to the right side of the deceased's neck: "The diagonally upward strangulation marks are a sign of suicide, but the "Yoshikawa line" appeared on the neck.
When being strangled, the victim will resist pulling on the rope due to too much pain, resulting in scratches.
This is another evidence of homicide."
"They are contradictory." Aso looked at Tang Ze and said, "Which one do you think is more likely?"
"Judging from the circumstances when the body was discovered, I am more inclined to commit suicide."
Tangze said: "After all, no one can put themselves into a suitcase and carry them to a refrigerated truck after committing suicide."
"That's true." Aso agreed: "Even if it's not a murder, the person who dumped the body still needs to be found."
"That's it. Thank you for your hard work."
Tang Ze took off his gloves and said: "There is only so much that can be found in the autopsy. The rest depends on whether the laboratory can find anything.
Let’s have a quick lunch together after get off work later?”
"No, no, Jun Hui has cooked a meal at home. Let's do it next time." Aso said with a smile and waved his hand.
"Then next time."
Karasawa didn't refuse after hearing this. After bidding farewell to Aso Minoru, he ordered coffee for the inspectors who were working overtime and then returned home.
After eating, Karasawa looked at the photos of the rope and fell into deep thought.
This rope really made him a little concerned.
If the rope strangling the neck is regarded as rope A, then the rope tied to the knot of rope A is regarded as rope B.
The knotting method of the A rope is called a mouth knot. This knot is very strong and is often used by rock climbers, rescue teams or camping enthusiasts as a special knot.
As for the knot of B rope, it is a very ordinary deadlock.
Looking at the two ropes in the photo, Tang Ze wondered why there were two.
However, there is currently no information from the forensic team, and Tangze has no way to get the answer. He can only list various situations and wait for tomorrow.
A night of silence.
Early the next morning, Karasawa, who was thinking about the case, had breakfast cooked by Ayako early and went to Kesouyan.
The report on the physical evidence related to the case was also placed on Tangze's desk.
"Senior, I have read the information and made some discoveries. I will send a copy of the information to the Metropolitan Police Department and tell them what I have discovered."
Koshizui Nanatsuki, who arrived before Karasawa, saw Karasawa coming, said hello, and hurried out.
Tangze didn't care what she found, he sat down and picked up the information and started reading.
The first is the rope.
The inspection report stated that the two ropes were made of the same material and were items in circulation in hardware stores.
The first is rope A, which is the rope that directly touches the deceased. The cross section of one end is the same as the cross section of both ends of rope B, which means that it is cut off by the same equipment.
Judging from the direction of fiber wear, the tool should be pliers.
The different ends of rope A are cut with a knife.
Although this was only a slight difference, after seeing this difference, Tangze felt something unusual.
Was it left behind after the deceased hanged himself and was discovered, and then the other party cut the hanging rope?
But the tools are different, and why?
Suppressing all the thoughts in his mind, Tang Ze continued to look down.
Regarding fingerprints, no fingerprints were found among the items left at the scene.
There were no fingerprints of the victim even on the rope.
This has obviously been erased.
In addition, DNA testing of the skin under the fingernails revealed that it belonged to the victim himself, which confirmed that the scar on the neck was the Yoshikawa line.
The evidence only goes so far, and there are contradictions again.
But Tangze still preferred homicide because the body was found in a refrigerated truck.
In addition, nitrobenzaldehyde, acetylene, sodium hydroxide, and barium hydroxide were detected on the pulley of the deceased's suitcase.
According to the analysis of the appraiser, these components should be synthetic blue dye, that is, indigo dye.
This stuff is commonly found in factories, and it is impossible to have these things in a normal environment.
In other words, it is likely that there was indigo dye in the place where the deceased died, so it was stained on the axle of the suitcase.
At the same time, the delivery route of the refrigerated truck is fixed. If the prisoner wants to put the suitcase containing the body on it, he can only take advantage of the delivery time.
This time won't be too long.
In other words, if there is not enough time, the factory will most likely be on the delivery route.
Thinking of this, Karasawa understood why Koshimizu Nanatsuki hurried to the Metropolitan Police Department.
It was obvious that she had thought of this. When she went to deliver the information, she also informed her of her discovery and asked the Metropolitan Police to search for places where these dyes were used along the route of the refrigerated truck.
The crime scene may not necessarily be discovered, but at least the location where the victim was placed in the refrigerated truck can be determined.
Not long after, Koshizui Nanatsuki came back. After some conversation, he found that it was exactly what he thought. Koshimi Nanatsuki also discovered this.
I just went to deliver information to the Metropolitan Police Department, and also told Officer Megure and others about the discovery. At this moment, they have followed the delivery route of the refrigerated truck to investigate whether there is any place where indigo dye is needed.
"Please bring the investigation information from the police."
Knowing that the police had already started taking action, Tang Ze stopped paying attention and asked instead.
"Through the traces of the teeth, the Metropolitan Police Department has found the identity of the victim."
Koshizui Nanatsuki said: "The deceased's name is Fujiyoshi Tomomi. She was 24 years old and was a dispatched employee. She was unemployed for the past three months.
She originally had parents and an older sister, but they died in a ship accident when she was in elementary school.
Now I live in the Nishi Ward of Aipido Town. Just now, Officer Megure said that they will immediately determine the specific address of the deceased and let us conduct scientific research and prepare it. We will go to the deceased’s house to search and collect evidence later.”
"I know, that's all the news at the moment. I hope there will be new discoveries from the deceased's family."
Tang Ze nodded and immediately said: "Notify the forensic team and let them prepare for departure."
"receive."
Koshimizu Nanatsuki nodded and immediately went out to call someone.
The group soon set off and arrived at Fujiyoshi Tomomi's home.
After entering the door, Tangze looked around: "The room looks very neat."
Recalling that there were no fingerprints on the items on the deceased's body, Tang Ze had a bad feeling when he looked at the tidy room.
To be honest, forensic officers do not like rooms that are too clean or too dirty, because one may be in vain and the other may be busy.
"But this also shows that the deceased's house is not a crime scene." Koshimizu Nanatsuki put on his white gloves and said: "Anyway, I'm here, let's see if I can gain anything."
After Koshimizu Nanatsuki entered the house, he first chose the nearest bathroom. Karasawa hadn't even taken two steps into the house when he heard her call.
"Senior, look."
Koshizui Nanatsuki pointed to the bathtub and found that the computer and mobile phone were soaked in it.
"I've been soaked in water for I don't know how long."
Seeing this, Tang Ze shook his head: "It's basically impossible to recover the data. Let's see if there are any other clues."
He said that, but in fact Karasawa didn't have much hope.
After all, the deceased's computer and mobile phone were soaked in water, which proved that someone had cleaned them.
In this case, it is unrealistic to expect clues.
However, after some searching, everyone still found something.
But it's not about the prisoner, it's about the deceased.
【I don’t want to live anymore, I want to die. If I die, will you cry? 】
"Is this a suicide note?" Koshimizu Nanatsuki couldn't help but be surprised after reading the contents on the letter.
"From a literal point of view, it is true." Tang Ze nodded.
"But isn't this case a homicide?" Koshimizu Nanatsuki frowned.
"Maybe, maybe not."
Tang Ze shook his head and said: "It's hard to make a judgment now, but judging from her identity and background, she has a miserable life experience and is a lonely person.
But what concerns me the most is the last sentence [Will you cry?]
It seems that whoever she is confiding to must be someone very important to her."
"This depends on whether the First Search Section finds anything." Koshimizu Nanatsuki said hopefully, "I hope there will be some progress."
"Humans are social animals, no matter how lonely they are, they will always have one or two acquaintances." Tang Ze smiled and said, "Don't worry about this, just wait for the results."
After finishing speaking, Tang Ze stood up and put the suicide note into the evidence bag, and then the forensic officers began to collect the evidence in the room.
But the results of the investigation were surprising.
The entire room was cleaned, and there were no fingerprints on the table, door handles, or windows.
That's right, even Fujiyoshi Tomomi's own fingerprints are not there.
Obviously, this was cleaned up by the prisoners in order to remove traces about themselves.
There were no signs of picking the door lock of Fujiyoshi Tomomi's room. The prisoner probably provided a spare key without authorization, or used a key given by Fujiyoshi Tomomi himself.
In other words, it is presumed that the criminal is someone very close to Tomomi who committed the crime.
In addition, the suicide note was also carefully checked and there were no fingerprints on it.
There was just a little red mark on the bottom of the letter paper, and Tang Ze had asked the person in charge of writing appraisal to pay attention to it.
After feeling that there was no gain, Tangze ordered the team to withdraw and return to scientific research.
After letting them go about their business, Karasawa took Koshimizu Nanatsuki to search the first class and get information.
It was better to arrive early than to arrive by chance. Just after Officer Megure finished telling their side of the news, they saw Takagi and Chiba, who had gone to inquire about the situation, returned from the investigation.
The two went to the place where Fujiyoshi Tomomi works to conduct an investigation.
According to the other party’s direct supervisor, Tomomi Fujiyoshi resigned because her labor contract with the dispatch company expired.
Her boss said that she was a very serious person, and after the contract expired, he planned to directly ask the dispatch company to perform for the duration of the contract, so that she could continue to work in the company.
But I didn't expect to be rejected by Fujiyoshi Tomomi, who said he wanted to take a rest.
In addition, the two also wanted to find out from her colleagues whether there were any friends with whom she had a good relationship in the company.
But it's a pity that she doesn't have the kind of friends in the company with whom she can discuss things.
According to colleagues in the same group, Fujiyoshi Tomomi is not very good at interacting with people, but is a very honest person.
One of the employees even said that once she accidentally stepped on Tomomi Fujiyoshi's foot and was apologizing exactly, but she didn't expect the other person to apologize first.
"Her presence in the company is very low."
Koshizui Nanatsuki said thoughtfully: "And in terms of personality, he is autistic and is afraid of causing trouble to others?"
"Are you asking her if she has any hobbies like rock climbing or camping?" Tangze asked.
"Yue Shui also told me about the mouth-shaped knot."
Takagi smiled when he heard this and said immediately: "But it's a pity that she doesn't have any hobbies in this area."
"But we did find out that Tomomi Fujiyoshi likes to watch dramas."
Chiba followed closely and said, "I heard it's a small theater troupe in Tokyo called Dongsheng Little Theater.
It is said that Fujiyoshi Yumi is friends with the actress in that small theater, and she is very happy every time she goes there."
"Where's the other party's information?"
After hearing this, Police Officer Megu asked: "Have you found anything?"
"Miwako is already investigating." Takagi said with a smile, "I think we'll find out after a while."
"Well, as soon as you know the news, go over and ask." Officer Megure explained.
"Understood!" Takagi and Takagi nodded seriously.
"Let's go too." Tang Ze said: "There are some things that I care about. Maybe I can find something by following them."
"Okay, thank you for the hard work, brother Tangze." Officer Memu didn't refuse after hearing this, and nodded in agreement.
The four of them rested in the office for a while, and soon Miwako called.
"Miwako went to the theater troupe, but the other party went to work in a handicraft shop and was not in the theater troupe."
After hanging up the phone, Takagi said: "I already know the address, let's go directly."
"No problem." Tang Ze nodded, and the four of them rushed towards the place where the other party worked.
"Is this Ms. Haruna Kawase?"
After entering the store, looking at Kawase Haruna who was busy, Takagi took out his police officer ID card.
"It's me." Kawase Haruna nodded and said, "Excuse me, what can I do?"
"You know Fujiyoshi Yumi, right?"
Chiba said: "We found her body last night.
I'm looking for you now because I have something I want to ask you."
