"When the car arrived at Iidabashi Station, it stopped suddenly." Keiko reminded in a low voice.

"That's right. Then I thought the deceased was deliberately trying to take advantage, so I gave him a gentle push. Unexpectedly, he slid to the ground. At that time, I thought why he was so weak... and I thought he was pretending.

Just kicked...kicked twice."

With a look on his face, Saoki interrupted and asked: "Recall, before the deceased fell into your girlfriend's arms, that is, before the bus arrived at Iidabashi Station, did the deceased do any special actions?"

"How did I know that?" Ichigo Seita looked nonchalant in response to the high school student's question.

After Jian Chiyong finished taking notes, he pressed the pen a little harder on the beige paper and said sternly: "Think about it carefully!"

"Um..." The yellow-haired young man scratched his cheeks with his hands, "I only know... the deceased seems to have been reading some magazine."

"Is it this one?" Kenmochi Yong shook the xx financial magazine that he had put in his evidence bag.

"probably!"

He asked the female forensic doctor who was still examining the body: "Is there something wrong with the magazine, Ono?"

The lenses reflected the warm light from the overhead light. Yumi Ono unhooked the mask and replied: "No, no lethal chemicals have been found on it yet. The specific results still need to be analyzed by the laboratory."

"Well, besides reading the magazine, did the deceased do anything special?"

"Really?" the yellow-haired young man asked himself, and immediately seemed to capture some memory points, "Oh... there was a moment, a few minutes before he fell, I noticed that his body was leaning to the left.

The left arm... holds an open magazine, yes, that's it!"

After listening to Chengtian's description, Saoki slapped his forehead and felt a little annoyed: "It turns out that when I put my hand into my trouser pocket, I was scratched by something inside. Why didn't I think of such a simple thing?"

"Ono-san, please check the deceased's right trouser pocket first, but be careful!"

"OK, all right?"

Ono Yumi, who was studying the wound on the palm of the deceased, nodded, took out the sterilized, fluorescent tweezers from the metal box, opened the deceased's right pocket as far as possible, and carefully took out the square cigarette box from the spacious gray trouser pocket.

Saoki squatted down and looked at it carefully for a long time, but did not find any needle-like objects on the surface that could scratch his palm. "Ono-san, is there something else inside?"

The silver tweezers continued to penetrate into the pocket, and her eyelashes blinked: "There is something else!"

Sagi and Isamu Kenmochi stretched their necks when they stopped asking.

A white cylinder made of foam board was taken out. The diameter of the cork-shaped cylinder is less than three centimeters. There are at least thirty visible sewing needles stuck on its surface. Each needle is about half a centimeter exposed on the surface.

, there is also a reddish-brown unknown substance on the tip of the needle, forming an exquisite hidden weapon as a whole.

Ono Yumi held it close to her eyes, squinted her eyes and looked up and down carefully. She found that the tip of the needle exposed on the other side was also condensed with a tar-like viscous reddish-brown substance. She sniffed it gently and immediately frowned and moved away.

open.

Jianchi Yong also took a sniff, trying hard to find a suitable description, "It smells a bit like...like moldy cigarettes."

Yumi Ono found a few discarded newspapers, stacked them up to hold foam cylinders filled with fine needles, and then used tweezers to pick out dark skin tissue at the tips of some needles.

"It seems that this is undoubtedly the murder weapon. Xiaoye, can you tell what kind of poison it is?"

"Nicotine?" Sagi whispered.

Ono Yumi handed the murder weapon wrapped in newspaper to the assistant next to her, who took it cautiously. Then she patted her white coat that was extremely clean, stood up, leaned against the metal pole, and looked at Zuo with interest.

He glanced at it, took off the mask, and said, "Nicotine! And the purity is quite high."

"No wonder I keep smelling a strong smell of smoke." Jianchiyong stood up and waved his hand, as if to disperse the air containing the strong smell of smoke.

Some passengers thought it was highly toxic gas, so they covered their mouths and noses and leaned toward the window. Just as they were about to open the closed window, Saoki said, "Don't open the window. It's okay to take a few breaths."

"Yes, under normal circumstances, nicotine is a transparent, colorless and odorless oily liquid, but it dissolves in water or stays in the air for too long, because there is also water vapor in the air," she explained with a wave of her hand, and continued:

"At this time it will turn dark brown and emit a strong tobacco smell.

"I have checked that there are no less than ten wounds on the palms and fingers of the deceased. When the sewing needle on the murder weapon pierces the palm of the deceased, nicotine will flow directly into the blood vessels from these wounds, and this poison will cause paralysis of the respiratory organs. I

It is estimated that the deceased died of the poison within a few minutes...

"Just after looking at the oral cavity, the deceased had a long history of smoking, so he was highly resistant to nicotine. It is really rare for him to be able to survive these few minutes."

Yumi Ono finished speaking in one breath and said no more. She pointed to the front door and said calmly to the police station: "It's really stuffy here. I'll go out and get some fresh air. I'll give you a detailed report when I get back."

"Yeah!" Kenmochi Isamu, whose cheeks were covered with beads of sweat, nodded lightly, turned to ask the high school student, "Samu, do you have any ideas?"

Sasaki held his right thumb down and said: "First of all, the fatal poison itself is nicotine. Ono-san who left has already explained it very clearly.

"Secondly," he pointed his second finger, "it's about the source of the murder weapon and poison. The murder weapon is quite small and interesting, but so deadly! Except for the nicotine poison smeared or poured on the needle, which needs to be purified, the other materials are very

Commonly found foam boards and sewing needles can be obtained with little effort.

"As for the source of the poison, the nicotine content of ordinary cigarettes is 34%. Of course, the high-purity nicotine liquid needed to commit the crime can be distilled from a large amount of tobacco. However, even if the tobacco purchased by the murderer was from normal and legal channels,

As long as he is patient enough, he can divide enough batches and only buy a small amount of tobacco each time, which is not easy to trace...

He held his ink umbrella, "What's more, because nicotine (nicotine), which is widely distributed in Solanaceae plants, has insecticidal effects, some pesticides on the market themselves contain high concentrations of nicotine. If you want to further purify it, just

It only needs to be heated a little. If Uncle Sword Holder investigates the source of the poison, it may be difficult to get any useful clues!"

Jian Mochiyong's sharp eyes scanned the more than thirty passengers standing in two rows. Most of them had a look of fear on their faces, while a few just wanted to watch the excitement. "Then aim at those who can get close to the deceased," he said.

And put the murder weapon into his trouser pocket!"
