"Smash the lock?" Chen Weibin was stunned for a moment, and continued to analyze, "Since the iron bars are constantly being made, Qin Guitian should have also thought about smashing the lock!" It is likely that he had been observing the iron gate for a long time, but he found that the cleaner had been there all along, either cleaning or maintaining the plants, and if the lock was smashed, it would have been loud and would have disturbed the cleaner. In this way, he will be exposed, and maybe he will be taken to the police station for vandalism. ”

"That'...... Can he choose to smash the lock at night? ”

"At night? In the dead of night, the sound is louder. The cleaners live in the dormitory ten meters next to the iron gate, and once the iron door makes a noise, the cleaners will definitely come out to check, and he can easily be caught as a thief, which is even more risky! ”

"According to your analysis, the possibility of entering through that iron gate to get the wig is basically gone." Li Jun nodded and continued, "Then he can get out of the park, go back to Fumanlou, and then walk from Fumanlou to the position at the intersection of the guillotine, and he can also get a wig?" ”

"Without the disguise of the wig, Qin Guitian would not dare to show his true face! Because ......"

Li Jun immediately took over: "Because he has a disability in his left leg, once he is captured by the surveillance camera, we will compare him with the woman's body and confirm that it is the same person." Then, if we do a portrait comparison, Qin Guitian will be completely exposed, and the camouflage we made earlier will completely fail! ”

"That's right! Qin Guitian, who didn't have a wig, didn't dare to take this risk. He wanted to get back to Fu Man Lou with no more than five options: walking, cycling, driving, taking a taxi, or taking someone else's car. No matter what the form, you have to pass through the main road below the Fu Man Building, and there, I took a closer look that day, there are at least a dozen cameras around, among them, there are several cameras from the traffic police department, and it is impossible for him not to be photographed by the surveillance. ”

"But...... Isn't the surveillance footage only stored for two months? If he had gone again on the afternoon of the day he dropped his wig, or the next day or the third day, two months had passed by now, and the surveillance footage would have been overwritten. Didn't the man who rented the house for Qin Guitian deliberately leave No. 2 on the second floor of Fuman Building empty for two months in order to overwrite the surveillance video? ”

Chen Weibin was silent for a while and said, "These two situations are very different! No. 2 on the second floor of Fuman Building was deliberately empty for two months, because there was no one living in it, and it would not attract the attention of the police at all, so they would take advantage of the opportunity that the surveillance video under the residential building was only kept for two months, so that the surveillance video was overwritten. And when Qin Guitian returns to the bottom of Fuman Building, there will definitely be a camera from the traffic police department among the surveillance cameras that can take pictures of him. Do you know, the surveillance cameras of the Miojiang traffic police department have all been upgraded in the first two years, and the video collected by the newly installed camera has been stored for a long time, about one year, and it is impossible for Qin Guitian to use the two-month coverage period. ”

"A year?" Li Jun asked in surprise.

"Yes, a year! I guess that since the man who rented the house knew that the surveillance video of the resident's downstairs could only be stored for two months, he must also know that the surveillance video of the traffic police department was stored for one year. ”

"In this way, Qin Guitian really won't come over from Fumanlou."

Chen Weibin stared ahead and said: "On the one hand, I am risking the risk of returning to Fumanlou to be exposed, and on the other hand, there is the risk of the wig being discovered by the police. What's more, if we hadn't found Qin Guitian through the red rope, the possibility of the wig being discovered by the police was too small. I guess Qin Guitian and the man behind him also thought the same way. ”

Li Jun nodded and said, "That's ...... Qin Guitian can go buy another pair of wigs, disguise himself as that woman again, and then go back to Fumanlou, and then avoid the monitoring in the alley to get it, it's okay! Even if it is captured by surveillance, it will not arouse any suspicion. ”

"They can plan it that way. However, this kind of wig is rarely sold in physical stores, I remember that there are only a few physical stores selling wigs in Tianmen Market in Zhongcheng District, and half a year ago, that area, including the physical store that sells wigs, has been demolished, and there are no physical stores selling wigs in Miojiang. The wig we found, according to the time calculation, should have been bought when Zhang Dahua sublet the house, almost more than a year ago. ”

"That'...... Qin Guitian can still buy it online? ”

"Online shopping is documented. Qin Guitian didn't dare to buy it himself, it was too easy to expose. And the man behind him is even more mysterious, and he will never make such a low-level mistake of leaving lifelong evidence. ”

"That'...... He can find someone else to buy it for him. ”

"There are some things that you have to do yourself. The more people who know, the more danger there is. Also, even if he finds someone to buy it for him, the wig style bought online is likely to be very different from the previous one. ”

Li Jun took out two cigarettes, handed one to Chen Weibin, lit one himself, and said, "Detachment Chen, everything is clear with your reasoning!" ”

"One hundred secrets! This mistake of the opponent gave us a chance! This is both accidental and inevitable! What kind of perfect sin is there in the world? No matter how cunning the fox is, it will show its tail after all! ”

"What do we do next? Arrest Qin Guitian directly? Li Jun asked.

"Nope! The current evidence is insufficient, and he can find many excuses to excuse himself. At this time, Chen Weibin suddenly thought of a very important thing, and hurriedly said, "Put the wig here first." If we find the wig, don't tell anyone about it, just the two of us know!" Remember! ”

"Okay. Detachment Chen, do you have any plans? Li Jun asked puzzled.

"I can't say it yet, but I'll talk about it then. Just keep it a secret! Let's go back to Fumanlou and drive back to the detachment. ”

The two walked to the gate of the park, took a taxi, returned to the vicinity of Fumanlou, and drove back to the detachment.

It was already half past five in the afternoon. Chen Weibin returned to the office, locked the wig in the safe, and then dialed Tao Chunqiang's phone and reported to Tao Chunqiang about the investigation of Qin Guitian in the afternoon, except for the finding of the wig. Then, Chen Weibin went to the detachment canteen for dinner, returned to the office, and was about to pack up his things and set off to Liao Rengang's house in Nancheng District.
