"You have almost forgotten this knowledge over the years, right?" Professor Liu looked at Sun Jie and said in the laboratory.
"I gave it back to the lab teacher a long time ago." Sun Jie was a little embarrassed: "Is this vortex mixer from Haimen Qilin Bell? That's amazing!"
"Our lab isn't that great, but the equipment is adequate," said Professor Liu's assistant. "The 5430R centrifuge is not that great, but it's adequate."
"Okay, let's not talk about this anymore. Let's get started. The workload this time is a bit heavy." Professor Liu said, "Check the ion source."
"CUR: 30.0, EP: 10V, IS: 5500V, GS1: 60 degrees Celsius, GS2: 55 degrees Celsius..."
…
It was somewhat in line with Bai Song's expectations, and the second case indeed occurred that evening.
The security guard, the security supervisor and another security guard here died of an overdose of zombie drugs and were shot dead by the police, while this person died of poisoning and taking sleeping pills.
It was not a common benzodiazepine or barbiturate, but a new type of sleeping pill with unknown ingredients. According to estimates by Sun Jie and others, the deceased had taken too many sleeping pills and faced the onset of poison, so he did not call 120 or anything, and died in his sleep over time.
Bai Song directly asked Professor Tang for help, found the best analytical laboratory, and asked Sun Jie to help.
The autopsy is currently being handled by Qin Wushuang and others.
These cases happened one after another, and everyone was worried about handling the cases.
"You should have learned all these things before," Professor Liu explained to his assistant while operating the machine. "It is obvious that full scan in ESI+ ionization mode is more sensitive than full scan in ESI- ionization mode..."
Sun Jie felt that he should not have come today. He could basically not help with anything here. Every time he came to the Criminal Science Institute or the university laboratory, the situation was basically similar.
But he also knew why Bai Song asked him to come. Encountering such things would definitely be a good thing for Sun Jie. After all, he could learn something, which would help improve his forensic skills.
Sun Jie's level has improved over the years, not only because there are countless cases for him to learn from, but also because Bai Song will always send him whenever there is an opportunity to come into contact with the big guys.
The calculations here were relatively smooth. In less than two hours, the situation of the relevant sleeping pills was confirmed, which was the relatively uncommon 7-aminoclonazepam. After receiving this news, all nearby pharmacies began investigations.
…
"You already know the situation of the deceased," Qin Wushuang said to Bai Song, "The people at the scene said that this person took sleeping pills and died. This is not inconsistent with the autopsy results. It is normal for people of this age to have trouble sleeping."
"I don't know why," Bai Song looked at Qin Wushuang, "I really feel that this old man looks a little familiar, but when I think about it carefully, I can't remember it at all."
"I recognize your memory. It all depends on fate," Qin Wushuang said. "If you can't find anything from this person's resume, you have to use his interpersonal relationships to find out where he usually moves around. Maybe you can match your memory with it."
"Yeah, that makes sense." Bai Song nodded: "Captain Qin, I find that you are becoming more and more adapted to the work of the captain."
"Actually, I still like to stay in the lab or the morgue and work on technology..." Qin Wushuang said, "But... I've been in this position for several years in a blink of an eye."
"Is the old man in good health recently?" Bai Song always said that he wanted to visit Qin Wushuang's father, but in the end he only visited him once.
"Very good. My dad is also a very interesting person." Captain Qin said, "He praised you last time."
"For this matter, I'll visit you again." Bai Song said with a smile.
…
The man on the street is as beautiful as jade and the gentleman is unparalleled in the world. When you think of the name that Qin's father gave to his son, you will know how broad-minded and magnanimous the old man was.
Bai Song followed Captain Qin's words and went to interview several family members of the deceased, and learned the approximate range of the deceased's activities over the years.
After this chat, it turned out that they hit it off!
This old man once went to the rooftop of the Health Hospital to play table tennis!
Bai Song wondered why it felt familiar. It was reasonable for him to feel familiar, since he had seen it before after all.
At that time, Bai Song had thought about it. There were not many people in the health hospital, and there was a prison opposite it, with no residential areas nearby. Why did so many people go there to exercise, keep fit, and read?
There is actually not a shortage of such places in Tianhua City. Some people may not care and some may have other reasons for traveling so far.
In this case, the matter at the Health Hospital is not completely over.
Regarding the things over there, Bai Song had found a hideout outside the Health Hospital, a base on the top floor that produced cosmetic drugs, and some clues about Feng Yiling.
"I have the contact information of some former doctors at the Health Hospital," Bai Song said, "I think I need to find some people who didn't go in at the time to learn more."
"What's the story behind this old man?" Liu Shuyuan asked, "I've read a lot of information, but I don't think he's some big villain or something."
"He must be an important person, otherwise he wouldn't have been assassinated like this." Bai Song said, "But don't worry, we'll investigate slowly. By the way, how are the little guy and the Northwest man doing now?"
"They are both very anxious now. Today they went to two places to look for someone, but they couldn't find anyone. One of the places was a place we didn't know about. After they left, we went to check again, but the place was empty." Liu Shuyuan said.
"Well, the on-site investigation must have already begun, so I won't waste any more time," Bai Song said. "Don't waste so much manpower and resources. Just arrest them. The little guy's involvement in this case is obviously much more serious than the others. Let's try him and ask him to turn in the things he buried before. Don't waste time. I don't have time to waste time with him now. It's obvious that these two don't know anything."
"That's the situation," Shu Yuan said, "Captain Ma and I also said the same thing."
"Oh, right, let them make the decision." Bai Song received Sun Jie's text message at this time. After reading it, he said, "The next part is the most difficult part of this case. I plan to read the previous case files from beginning to end. I want to see what the ultimate purpose of these people is."
"What about the port?" Shu Yuan asked.
"The main force is over there, so let's just stay there. We can't rule out the possibility that these cheap goods are still not the most important things, or there may be other fish that slipped through the net." Bai Song said, "Let's do our own thing. I'll call Brother Jie back and we'll meet up."
