Tang Zao continued: "Rohypnol was detected in the bodies of the two deceased, which is a psychotropic drug that has hypnotic and sedative effects, and can be classified as a poison if it is not used for medical treatment. Product range. Soluble in alcohol and can interfere with people's memory, so it is also known as dating strong. Violent drugs. It will take effect in about 20 minutes after consumption. ”

Lu Xiaozheng frowned: "So when the deceased was attacked, it should be in a state of delirium?" That's why you didn't struggle to call for help? ”

Tang nodded early, "I think so, after all, there is no fracture in the forehead, and the force to hit the ground is not very great." ”

Jiang Wei said: "What is the way to take the medicine?" ”

Tang Zao said: "Intramuscular injection, intravenous administration, and intranasal administration have been ruled out, so the way should be oral, but the strange thing is that no ethanol was found in the stomach contents of the deceased." ”

Lu Xiaozheng muttered to himself: "Dry swallow? ”

Jiang Yu said: "Could it be *?" Kissing or feeding? ”

"Possibly."

Tang Zao said: "In addition, there is a special point, the deceased's left wrist was cut, the position is similar to cutting the vein to commit suicide, but the wound is not deep, and the tools used should be similar to eyebrow trimming knives and the like, which are relatively thin and sharp...... Does this represent some kind of psychology of the murderer? ”

Jiang Yi stroked his forehead and groaned: "It's similar to cutting the veins to commit suicide......"

The identities of the two deceased have been clarified, and judging from the data, except that they both lived nearby, there was no commonality, no related interpersonal relationships, and no clues of vendetta or love killings were found.

Lu Xiaozheng had no idea for the time being, and put together the materials: "Let's check first." He stood up and turned to Jiang Yu again: "The murderer may have his own reasons for choosing this section of the road, you take someone to investigate, all the cases that have happened on Antai Road in recent years, the scope is ...... In ten years. ”

The murderer apparently consciously avoided the surveillance cameras, but the section of the road where the incident occurred was close to Qingshi Station, and most of the roads along the road were hotels and restaurants, even if it was late at night, there would be taxis carrying passengers by from time to time, and it was likely that someone would see it.

The criminal investigation detachment was divided into three groups, and Qiao Nan Guo Bai's second-line officers also came in handy, and they were dispatched, together with the police officers of the sub-bureau, to start the trivial investigation work, and at the same time, the people who stayed in the bureau were also checking the passing vehicles during that time period through monitoring.

There are not many vehicles passing by, most of them are taxis, many cars are equipped with dash cams, but most of the dash cams are stored for only a few hours, and the taxis are running outside all day, and the records are quickly washed away, and only two cars can still find the picture of the second case.

The picture is very clear, at about the same time, there is a taxi parked there, there is no street light, the license plate number is not clear, from the location, the position where the deceased is lying is on the inside of the car!

Lu Xiaozheng suddenly frowned: "It's broken!" ”

If this person's means of transportation at the time of the crime was a taxi, and they had previously investigated the taxis passing by during that time, then the murderer must be among these people! I'm afraid I'm already awakened at this time!

Ye Guining quickly adjusted the picture of the two recorders clearly, the city's own vehicles of the taxi company, the seat cover is a unified customized white seat cover, plus the annual inspection sign of the front windshield can not be seen clearly in the dark light, no way, can only call up the monitoring of the front and rear intersections, compare them one by one, less than 500 meters between the two intersections, it should take less than two minutes to drive, but there is a car with a license plate number of T1886, and there is a full gap of eight and a half minutes in the middle!

The surveillance at the intersection captured the driver's face, which is not very clear, it is a man in his thirties, with a scruffy beard, looking quite sloppy, and not wearing a mask. Lu Xiaozheng stood up directly: "Come on, let's take a look." ”

Tang Zao stood up and went out with him, Lu Xiaozheng sat directly in the passenger seat, Tang already knew that he wanted to think about things, and he didn't bother him, and drove all the way to the taxi company, Lu Xiaozheng said in a low voice: "I think something is wrong." ”

But why exactly something was wrong, he didn't say. This is purely a detective instinct, and it may not be founded, but it is true many times. Moreover, in the absence of other clues, it can only be investigated in this direction.

They found the registration information of the car from the taxi company, the driver's name is Zhao Pu, he still went out of the car normally in the morning, and when the bureau called to inquire about the situation, he also answered the phone, but now he calls again with the taxi company's phone, and he does not answer.

Lu Xiaozheng was not surprised, and while calling someone to locate and find it, he and Tang Zao rushed to the community where he lived.

Theoretically, if the person was alerted after receiving the phone call and had thoughts of running away, he would have to go home and pack his things. Lu Xiaozheng called the police to go over and stare first, and in less than half an hour they also arrived, the security guards in this dilapidated community were useless, and the door was wide open, they went directly to the man's house, and no one answered after knocking on the door for a long time, Tang Zao turned his head and knocked on the opposite door, there was a fourteen or fifteen-year-old boy in the house, saying that he didn't hear him come back.

Answered the phone and ran away?

Lu Xiaozheng made a phone call to transfer someone to keep an eye on it, and came out with Tang Zao, while saying, "I still feel that something is wrong." The whole line is not smooth, how did the suspect let the female deceased take oral drugs? The female deceased lived nearby, why did she take a taxi? Where are you going? Tang Zao hummed, let him think about it by himself, and she went over to talk to a few aunts sitting downstairs.

After all, this is not a temporary murder of passion, but a brutal killing of two people in succession, so in general, the murderer will be a little different from ordinary people.

But the strange thing is that the aunts have a very good impression of this Zhao Pu, saying that he has a neat mouth, and everyone he sees is self-cooked, but he is a little slippery, and he loves to be cheap, and there is nothing wrong with him.

was chatting, and suddenly heard a person laugh and said, "Xiao Tang? ”

As soon as Tang Zao turned around, it was Xue Baibi, who she hadn't seen for a long time, and she was a little surprised: "Sister Xue? ”

Xue Baibi snorted, walked over with a smile, nodded to a few aunts first, and then said, "Why are you here?" ”

Tang Zao said: "I'm here for some business, why is Sister Xue here?" ”

Xue Baibi said: "My mother lives here, I came to see my mother." She took her hand, gentle and gentle: "It's been a long time, I miss you so much, why haven't you come to me recently?" How's your business going? ”

Tang Zao sighed: "I've been too busy at work lately, one case after another, and I'm a bunch of bad things myself, haven't you watched the news?" I really don't bother to look it up, and I don't have time to look for you, I'm sorry. ”

She patted the back of her hand with a smile: "A person's energy is limited, you still have to pay attention to your body, you have lost weight." ”

The two exchanged pleasantries for a while before she walked into the car, Tang Zao smiled and waved his hand at her, turned back, and still said to an aunt: "Then do you know that Zhao Pu has any familiar friends?" ”

While speaking, Xue Baibi drove past behind a group of people, and after a while, one of the aunts suddenly said, "Are you a policeman?" ”

Tang Zao said: "Yes." She was keenly aware of something: "What's the matter, auntie, you can say something." ”

Auntie looked at a few old sisters around her, and said in a low voice: "You are quite familiar with the old girl of the Xue family?" ”

In fact, Xue Baibi is in her fifties, and the age of these aunts is not much different from her, but the customs of Qingshi are called "daughters" if they are not married, and those who are older are called old girls, which sounds like two generations.
