The next day, in the CID conference room, Madam Lei made a rare appearance in the conference room: "Tell me, how is it now?" ”

Zhang Dayong said: "Forensic and forensic reports have been sent, according to Dr. Nie's report, Lu Wanmei's time of death was between 3 and 4 o'clock, that is, when the security guards found the body, I believe that the murderer just left." In addition, Lu Wanmei died because she was strangled by a hose in her throat, and she was sexually assaulted before her death, and Dr. Nie also detected Ge Luofang in Lu Wanmei's body, and deduced that the murderer first used Ge Luofang to stun Lu Wanmei and then killed, but no jing fluid was found in the deceased's body! In addition, in terms of forensics, no suspicious fingerprints were found on Lu Wanmei's body, and it is believed that the murderer was likely to be wearing gloves at that time! ”

Li Zhongyi said: "Last night we caught the deceased's boyfriend Huang Chengcheng, but I inquired with my colleagues at the Sai Kung Police Station today, and Huang Chengcheng was indeed caught by our colleagues at the police station at the time of the crime, so it is impossible for the murderer to kill him!" ”

Xu Fei said: "Brother Xiong and I went to the Tianshangtian Nightclub again last night, and found Lu Wanmei's sisters who are usually familiar with each other, and found several of Lu Wanmei's regular customers and acquaintances to ask, but there was no time to commit the crime!" ”

After listening to this, Madam said: "Lu Wanmei's purse was found at the scene of the crime before, and cash, bank cards and other property were there, so it would not be a robbery; Lu Wanmei's boyfriend didn't have time to commit the crime, so it shouldn't be a love killing? Xu Fei asked Lu Wanmei's regular customers and friends again, and there was no suspicion, so the possibility of acquaintances committing crimes was also very low? ”

Meng Bo said a little frustratedly: "It's not a love killing, it's not a habitual offender, it's a random crime, right?" The murderer followed Lu Wanmei, and then there was no one to be stunned, and then he was killed? ”

Defen spread his hands: "According to what you say, we are not looking for a needle in a haystack, how can we check?" ”

Li Zhongyi scratched the case and said: "It's a pity that the convenience store clerk who witnessed Lu Wanmei passing by before didn't notice whether anyone was following Lu Wanmei!" Otherwise, we have a clue! ”

Madam said: "Don't complain, even if it's a needle in a haystack, you have to fish it out for me!" After speaking, he looked at Zhao Damao: "Da Mao, you haven't spoken, do you have any opinions?" ”

Zhao Damao frowned and said: "How do you look at the murderer this time, he is a thoughtful person, and he made a careful plan before committing the crime, and prepared Ge Luofang, so that the victim will not make a sound to alarm others; If you prepare gloves, you won't leave fingerprints; If you have a condom ready, you won't leave any DNA! The murderer had made so many preparations, if it weren't for the deliberate revenge to kill Lu Wanmei...... I guess the killer may have committed other similar cases before, or maybe this is just the beginning of the murderer! ”

As Zhao Damao's words fell, the atmosphere in the conference room became tense, and Zhang Dayong said: "You mean this is another serial killer like Vanness last time?" ”

Zhao Damao nodded, the serial killer is the most headache for the police, because if the case cannot be solved as soon as possible, the pressure on the police station from top to bottom will be great!

Meng Bo whispered, "Not necessarily, right? Didn't Lu Wanmei have a condom in her bag? Ge Luofang will have a lot of old boys, maybe which old boy saw Lu Wanmei's sexy dress and became lustful, and when he saw no one around, he wore gloves and stunned her, and when he was doing errands later, Lu Wanmei suddenly woke up, and the murderer inadvertently strangled her! ”

Zhang Dayong rolled his eyes: "The box with condoms in Lu Wanmei's leather bag hasn't even opened the package!" And according to what you said, Lu Wanmei suddenly woke up, she will definitely resist, right? And the autopsy report has already written that Lu Wanmei did not fight or resist injuries! And how many Tricky Boys are so thoughtful? ”

Madam Lei stood up: "Now that we can't discuss anything, let's go out and investigate!" Since Lu Wanmei was killed on the way to get off work, the murderer is likely to follow her all the time! From the nightclub where Lu Wanmei worked to the place where she was killed, I don't believe that there was no eyewitness along the way! I will also go to other police stations to ask if there are any similar cases recently! ”

“yes，Madam！”

Zhao Damao took Xu Fei to the convenience store that Lu Wanmei passed by before she was killed.

Walking into the convenience store, the clerk standing at the cash register happened to be the clerk who witnessed Lu Wanmei passing by that day.

The clerk watched Zhao Damao come in: "Sir, why are you here again!" After you asked that day, your colleagues came to ask, back and forth several times, and our boss thought that I had caused something, and I would be fired if you continued like this! ”

Zhao Damao was also a little embarrassed when he heard it: "I'm sorry, we also want to find clues as soon as possible!" ”

The clerk said unhappily: "This is your policeman's business, and it has nothing to do with me!" ”

Seeing this, Zhao Damao took out his wallet and took out a thousand-yuan bill: "As long as you are willing to cooperate with us, I can compensate you!" ”

The clerk's eyes lit up, he walked out of the cash register, pulled Zhao Damao to a corner, and then took the money from Zhao Damao: "It would be good if you did this earlier!" But all I saw was what I told you that day, but you've already given me the money, and I'm not going to pay it back! ”

Zhao Damao looked at the palm-sized convenience store, why was this clerk so careful? So he waved his hand indifferently: "It's okay, this is what you deserve!" However, why are you so careful about collecting some benefit fees? ”

The clerk said helplessly: "I don't want to either!" Our boss withheld and searched for fear that we would be greedy for his money! There's a CCTV at the cash register, and if he sees me taking money from you, he'll probably think I'm embezzling money from the store! ”

Zhao Damao's eyes lit up: "Where is the CCTV?" ”

The clerk pointed to the decoration on the wall next to the cash register: "That's it!" ”

Zhao Damao was speechless for a moment, how strange and advanced this boss is, and there is an ornament outside the camera to cover the fuselage! In recent years, CCTV monitoring itself has not been popularized, and this kind of convenience store is used even less, and now it is still camouflaged, so Zhao Damao didn't find it at all before!

Zhao Damao followed and said, "Take us to see the surveillance footage!" ”

The clerk nodded, loaded the money given by Zhao Damao, and returned to the cashier.

Zhao Damao and Xu Fei followed into the cash register, only to find that there was a small locked cabinet under the cash register, and a small monitor was placed on the small cabinet!

Xu Fei glanced at the screen of the monitor: "Da Mao, look!" I can shoot outside! ”

Zhao Damao fixed his eyes, although the angle of the camera was relatively low, but it could indeed capture the scene on the road outside.

Zhao Damao said to the clerk: "We want to watch the video of the day before yesterday!" Do you have? ”

The clerk shrugged his shoulders: "You also saw it, there is a monitor outside, the other equipment is locked in the cabinet, and the key is with our boss!" However, I heard from my boss that the footage can be kept for a week, and the footage of that day should still be there! ”
