Cheng Xiao smiled with satisfaction, and this sentence just came to his heart.

I have a little more appreciation for Gu Xia, "Tell me, why do you think so?"

Gu Xia raised his head and looked at the ceiling, "During the autopsy of the three victims, they were found to have been injected with wa2 super anesthetic before the accident. I have read the information of this anesthetic, and the effect is amazing. It is said that a small amount of vial can knock down an elephant, and there is a high risk. In other words, if used too much, it will damage the brain nerves and even die directly... The autopsy shows that the victim died eight or even ten hours after being treated with anesthetic. What does this mean?"

Cheng Xiao listened very seriously and did not interrupt.

"This shows that the murderer is particularly good at anesthetics and knows the efficacy of this medicine very well. He can ensure that the victim is caught and not fatal. He must use this dose very accurately. He first anesthetized the victim with anesthetic, and then sexually assaulted. After sexual assault, he may imprison for a period of time... Finally, he lost his patience, cut his throat and killed the victim, and then ran to the wilderness or Hu Bo. The three cases are like this. I don't think this is a coincidence. The murderer is either a doctor or anesthesiologist, or a person who has been exposed to this anesthetic often."

Cheng Xiao nodded, "It's very convincing. I think so too. In this way, our investigation can be narrowed to the medical industry, so that there will be fewer difficulties and no needles will be found in a haystack."

Gu Xia nodded and continued, "Wa2 is a new anesthetic that was released worldwide in March 2018. It was officially approved to enter the country in June 2018. In fact, there are not many people using this in China, because the risk is too high. It is usually only used during large-scale craniotomy or venting surgery. I think there are not many people who can get this in our city G."

"I understand, I will ask someone to investigate all the inventory and handling people of this anesthetics in the seven Grade A hospitals in this city."

Gu Xia nodded...

"Xiao Xia, you are so smart. I really regret not getting you here earlier." Cheng Xiao was a little excited.

"Don't put a high hat on me, Team Cheng, I won't eat this set."

"Are you hungry? Please have a midnight snack?"

"Forget it, I'm a little sleepy and want to go home to sleep."

"Okay, then we will continue to check tomorrow morning."

"good."

"How long do you think it will take to catch the suspect?" Cheng Xiao couldn't help asking.

Gu Xia tilted his head and pondered for a while.

"It's only three days, and you should be able to catch people within 72 hours, provided that this person doesn't leave City G."

"He won't run away. According to my past experience, this kind of serial murderer has serious antisocial personality. Once he kills one, he won't stop. I'm afraid that innocent girls will be killed before we catch him."

"Actually, I think we should publish this news and let everyone be careful. Have you not found a characteristic?"

Cheng Xiao was slightly stunned, "What?"

"The three victims are between 20 and 25 years old, which means that the murderer likes young women and looks quite sweet, which means that the murderer likes cute girls. At least they are good-looking, and the professions they engage in are salesmen, cashiers and nail salon owners. It means that he likes to attack grassroots women, which is what the big TV series calls Cinderella, and the three women wore black lace underwear on the day they were killed."

Cheng Xiao's cheeks turned red...

"You don't have to blush. I'm just telling the truth. This murderer may have a hobby on one side. He shouldn't be killing people randomly." Gu Xia said calmly.
