"Now I finally know why she was reluctant to cooperate with us when she went to the hospital to see President Luo last time. ”

"yes. At that time, he should have been worried about his reputation, but later he still lost his daughter's grief, and the idea of avenging his daughter took over. ”

Back to the serious crime team, as Song Jin almost recounted the narration of President Luo Xiluo that he heard in the ward, Qi Zhibin took notes at the same time.

The technical department also quickly made a thorough inspection of the sanitary napkin found behind the toilet in Hu Yuan's bathroom and under the water tank. And the residue in the middle layer of the sanitary napkin was detected - a plastic that degrades tens of thousands of times faster than the common ones on the market. It was the same substance as the test sheet issued by the forensic doctor of the city court that Luo Xi handed over to Song Jin.

As for the other item of "residues of highly volatile chemical reagents" mentioned in the inspection report, the technical department did not find it from the time of obtaining the sanitary napkin.

It's easy to understand when you think about it. After all, Rosie only sent the sanitary napkin for testing after less than ten hours. However, the sanitary napkin from Hu Yuan's IKEA was delivered to the technical department on the afternoon of the second day after the incident, to be precise, it should have appeared after 20 hours. Since it is an extremely volatile chemical reagent, it must have been exhausted in twenty hours.

"What do you think?"

"Team Fu, could it be an aphrodisiac or something like that?"

"Yes, Team Fu. Song Jin took Qi Zhibin's words and analyzed slowly: "It is certain that no matter where the sanitary napkins are produced, there will never be any interlayer left when they leave the factory." In other words, the sanitary napkins used by President Luo's mother and daughter were secretly manipulated - a plastic container that contained a small amount of highly volatile aphrodisiac and could quickly degrade was placed in it that was too small to be noticed.

When the container bursts when squeezed by a small external force, the gas emitted by the aphrodisiac inside has an effect on the victim's physiology, so that there is an inexplicable phenomenon of excitement as President Luo said. ”

"Makes sense. If we continue to reason along this line, it is not difficult to explain the meaning of the sentence in Yang Wenjing's autopsy report, "The deceased had sex with others while he was conscious and physically and mentally happy." ”

"So, we should now focus on tracing the origin of this sanitary napkin. ”

"Okay, I'll call the Forestry Bureau right away. ”

understood what Song Jin meant, so Fu Yuan quickly dialed the phone of Director Lin Jia of the National Security Bureau, and after a brief greeting, he said, "Forest Bureau, let Song Jin tell you." ”

Song Jin took the phone and once again repeated in detail what she had heard from Rosie in the senior cadre ward of the People's Hospital.

"Okay, you give the phone to Team Fu. ”

Fu Yuan took it and listened to Lin Jia say, "Team Fu, you guys should first contact Yang Yuting head-on." However, remember what we mentioned at the last meeting. ”

"Don't worry, I know it. ”

Hanging up the phone, Fu Yuan looked at Qi Zhibin and Song Jin, pondered for a moment before saying, "In this way, Xiao Qi will call Yang Yuting first as a serious case team to make an appointment." It's better this afternoon, don't drag it any further. After meeting with Yang Yuting, Song Jin will interrogate, and Xiao Qi will only make a record. ”

The first time he heard Fu Yuan arrange the details of the work, Qi Zhibin inevitably had doubts in his eyes, but he still agreed decisively, and then grabbed the phone in the office and dialed Yang Yuting.

"Hello, it's Professor Yang Yuting, right?"

"It's me. Who are you?"

"Hello Professor Yang, I am Qi Zhibin from the Serious Crime Team of the Municipal Bureau. Because of Yang Yutang's case, we need to find out a little bit about Professor Yang. I wonder what time Professor Yang is convenient in the afternoon?"

"Hmm...... Yang Yuting on the other end of the phone just pondered for a moment and said, "Then it's half past three in the afternoon, I'll wait for you in the school office." ”

"Okay, Professor Yang. ”

Because at this time, Xun Jianguo had summoned Yang Congwen, the general manager of Dousheng Hotel and Yang Yutang's nephew, to the serious crime team, so the two interrogated Yang Congwen together. After that, after lunch and a short rest, I went out at three o'clock and drove straight to the University of Science and Technology, and appeared in Yang Yuting's office on time at half past three.

"Hello Professor Yang, I am Qi Zhibin from the Serious Crime Team, and this is my colleague Song Jin. ”

"Hello, Professor Yang. ”

"Officer Qi, Officer Song, please be seated. ”

Let the two of them sit down on the sofa first, turn around and bring the tea that has been brewed a long time ago and hand it to Qi Zhibin and Song Jin.

Taking advantage of the opportunity, Qi Zhibin and Song Jin also carefully observed Yang Yuting in front of them

A slightly emaciated figure, a fair complexion, and a casual dress that is both decent and neat. There is always a gentle smile on his face, and his eyes also give people a very sincere feeling.

No matter how you look at it, Yang Yuting in front of him can't be associated with the word "suspect".

"Professor Yang, Xiao Qi already told you on the phone before we came,......。 ”

"Alas——," Before Song Jin finished speaking, the gentle smile on Yang Yuting's face disappeared, and his eyes dimmed for a moment, and then he sighed and said, "I really didn't expect that my eldest brother would suffer such a misfortune." As he spoke, he stretched out his hand and pulled a chair, sat down opposite Qi Zhibin and Song Jin across the coffee table and said, "If you have anything to say, just ask." ”

There wasn't much to say, the expression on Yang Yuting's face already showed his attitude at this time - he must know everything.

"Professor Yang, we also deeply regret the unfortunate experience of Chairman Yang. So far, there has been significant progress in the case - although the suspect has fled after the incident, the bureau has issued a notice to assist in the investigation throughout the country. I believe that it will not be long before the suspect will be brought to justice. ”

"That's good, that's good, thank you so much. ”

"Professor Yang doesn't need to be polite, this is our business. Song Jin looked directly into Yang Yuting's eyes and said, "I came here today to learn from you about some issues related to the other two cases implicated by Chairman Yang." ”

"The other two cases? What does Officer Song mean by that?"

"According to the evidence we currently have, Yang Yutang is related to three tattoo cases in the city. Moreover, it is also closely related to the recent murder of Yang Wenjing, a student of the automation department of your school, in the Jinghua community. ”

"What?!"

Whether it was the expression on his face or the eyes in his eyes, Yang Yuting was extremely surprised. So much so that Song Jin and Qi Zhibin didn't find the slightest abnormality from it at all.

"Professor Yang, as far as you know, do Yang Yutang and Yang Wenjing know each other?"

First shook his head, as if he hadn't recovered from the shock just now, and after a slight pause, Yang Yuting said, "This is impossible." Since Yang Wenjing loves English, I happen to be her English teacher, so we are still familiar with each other. As far as I know, there is no intersection between Yang Wenjing, a college student, and my eldest brother, who is the chairman, regardless of work and life. Naturally, there is no way to talk about knowing or not knowing. ”

"Then does Professor Yang know what bad habits Yang Yutang has?"

"Bad habits?" Yang Yuting said without hesitation: "Smoking, drinking, gambling, playing with women." My eldest brother has all of these problems. ”

Speaking of this, Yang Yuting's face was no longer the sad look he had when he first mentioned Yang Yutang's murder, but an expression of hatred that made iron but not steel.

"What else?"

"For example?"

"For example, I like to collect silver videos. ”

"I don't know about that. ”

"For example, money laundering, or doing something illegal and shady business?"

"No, the assets of the Dousheng Group under the name of the eldest brother are not less than billions, what is he not satisfied with, why do he have to do things that are not allowed by national laws?"
