There is a strange phone number in Lan Lan's cell phone call history. This number only has three call records, and all three calls were with Lan Lan, and they were all on the day Lan Lan disappeared.
The first call was when Lan Lan just went out at noon; the second call was around two o'clock in the afternoon, when Lan Lan was shopping in the mall; the third call was at three o'clock in the afternoon, when Lan Lan came out of the south gate of the mall. . The number that Lan Lan was talking to was shut down the day after Lan Lan disappeared.
Obviously, this was the mobile phone number used by the murderer specifically to commit crimes. After inquiry, it was found that this mobile phone number indeed belonged to a "black card". There was no real-name registration, and there was no owner information in the communication company. There is also such a strange phone number in the mobile phone call records of the other four ladies, and each number is different.
This kind of "black card" is already difficult to apply for through formal channels, but through online stores or virtual operators, you can find a large number of sources to choose from.
Therefore, this clue cannot be pursued further.
Yongcheng police retrieved the surveillance camera of the mall where Lan Lan visited before she disappeared. After some searching, the police officer responsible for watching the surveillance told Li Zhudao half-jokingly: "It's a bit mysterious that Lan Lan disappeared. Maybe there was some supernatural event." "
Li Zhudao thought this was a fantasy. After understanding the basic situation, he felt incredible: How could a living person disappear on the street in broad daylight?
Surveillance surveillance showed that after Lan Lan came out of the south gate of the mall, she walked towards the busy roadside. At this time, Lan Lan walked out of the surveillance range and then disappeared out of thin air.
There is a surveillance camera 25 meters away from the east side of the south gate of the mall, and the probe can just capture part of the area in front of the south gate of the mall. After careful inspection, there was indeed no figure of Lan Lan in the picture. The probe closest to the mall on the west side is installed in front of a nearby hotel. This probe can capture the entire sidewalk going west from the south gate of the mall. There is no figure of Lan Lan on this sidewalk.
Lan Lan walked out of the mall from the south gate, neither going east nor west. Could it be that she had grown wings and flown away?
Rather than believing in ghosts and gods, it is better to believe in the greed of human nature and all kinds of bottomless crimes that break through imagination in order to satisfy desires. Many times, human nature is scarier than ghosts and gods.
Li Zhudao firmly believed that there must be something that the police overlooked. It was impossible for a living person to mysteriously disappear in a place with such dense surveillance and dense crowds.
So, Li Zhudao, Liu Chaogui, and Xiao Wu went directly to the mall.
In the surveillance video, Lan Lan came in alone from the south gate of the mall, and when she left, she also walked out from the south gate alone. During this period, Lan Lan stopped in several stores selling women's underwear, cosmetics and jewelry.
Shopping guides who had contact with Lan Lan in these stores told Li Zhudao that Lan Lan only selected the products in these stores and briefly inquired about the prices, but in the end she didn't buy anything. After Lan Lan left, the shopping guides never saw her again.
Li Zhudao walked out of the south gate of the mall and looked at the busy scene in front of him. After staying for a while, he first walked 20 to 30 meters east, looked up and saw the surveillance on the east side outside the south gate, then returned to the south gate of the mall and continued After walking more than a hundred meters to the west, I finally saw the probe in front of the hotel.
Outside the south gate of the mall, the surveillance cameras on the east and west sides are nearly 150 meters apart.
"Please ask the comrades in the team to check again to see if there is still a surveillance blind spot outside the south gate. Lan Lan should have disappeared in this blind spot." Li Zhudao said to Liu Chaogui.
The technicians quickly got feedback: there was indeed a monitoring blind spot about 50 meters long in front of the south gate of the mall.
This blind spot immediately became the focus of investigation.
If Lan Lan was kidnapped, robbed, or taken away in broad daylight on a street in a blind spot, he would definitely be seen by pedestrians on the street or employees and customers in shops along the street, and no one would call the police. Even if this is true, now that the police come to inquire, it is impossible for everyone to open their eyes and lie, saying that they did not see any sudden violence at that time.
Therefore, Li Zhudao speculated that Lan Lan probably entered a certain store in the blind area and then "disappeared" in this store.
So, the three of them began to visit the shops and people in the blind area.
There are four relatively large stores in the blind area.
One is an Internet cafe, with the entrance on the first floor, and the second floor is the game area; one is a restaurant selling rice noodles; one is a fishing gear shop; and the other is a coffee shop. Waiters at restaurants and coffee shops told Li Zhudao that they had never seen Lan Lan in the photo. Customers in fishing gear shops and Internet cafes are usually dominated by men, especially in Internet cafes, where most of the customers are students. The shop owner and the front desk also said they had never met Lan Lan.
In other stores, everyone said they had never seen Lan Lan.
Liu Chaogui sent the personal information of these shop owners and clerks back to the police team. After screening, his colleagues in the team told them that these people had no criminal records, which meant that it was unlikely that these people had committed crimes or lied.
After visiting these shops without success, the manhole on the blind road caught Li Zhudao's attention again. It is impossible for Lan Lan to grow wings and fly to the sky, but it is possible that she fell into the manhole and burrowed into the ground. On this section of the road, it happened that some underground manhole covers were missing, and only a dark circular hole was exposed on the road.
Li Zhudao immediately called for the sanitation workers responsible for this section of the road. Under the guidance of the sanitation workers, the three people drilled down and carefully searched each manhole. The results were still disappointing. No abnormalities were found in the manholes.
Pedestrians, vendors, shops, manholes, and all possible situations in the blind area have been checked. It's not within the surveillance range, and it's not in the blind spot either. Could it be that he crossed the road and walked to the other side?
This possibility is extremely slim. There is also a large shopping mall across the road, but the two shopping malls are separated by a wide two-way 12-lane road, and there are green belts and guardrails in the middle of the road. There are no sidewalks, so it is very difficult to cross.
Just in case, Li Zhudao asked Xiao Wu to check the surveillance of the mall opposite, but as expected, Lan Lan was not seen on the surveillance of the mall opposite.
Li Zhudao squatted on the curb in the blind spot and smoked a cigarette until a taxi stopped two or three meters away from him. As soon as the door opened, a pair of long legs covered with black stockings stretched out from the car, and then this With his long legs and a pair of high heels, he walked into the mall behind him. Li Zhudao suddenly realized it, and then slammed the butt of his cigarette on the ground: "It's so simple, I didn't even think of it..."
There was no bus stop in the blind spot. After Lan Lan came out of the south gate of the mall, she neither walked east nor west. Instead, she probably took a private car or taxi on the side of the road.
There is a green belt in the middle of this section of the road within the blind spot. Vehicles cannot turn around, and the road runs east-west. After Lanlan came out of the south gate of the mall, her side of the road could only carry vehicles leaving from west to east. go.
Li Zhudao and others immediately returned to the police station.
Based on the "black card" phone number and the time of Lan Lan's last call record, technicians first checked the taxis that passed through this section around this time. Li Zhudao believes that the murderer most likely invited Lan Lan into the car through a "black card" phone call.
Nearly 30 taxis were investigated. After extracting the personal information of these taxi drivers, the police believed that their suspicions were not serious because they were all men, and the plastic bags containing "fried liver" The fingerprints on the phone have directly identified the suspect as Qin Rongrong.
But Qin Rongrong might also have taken a taxi to pick up Lan Lan outside the south gate of the mall. The police had to invite dozens of drivers to the police station to ask them to identify the photos of Qin Rongrong and Lan Lan, but they all said I have never given a ride to these two women, nor do I know them. There are no call records with Lanlan or the "black card" on these drivers' mobile phones, and their daily itineraries are completely traceable.
This means we can only continue to investigate private cars. What's troublesome is that during the time when Lan Lan disappeared, there were not even one thousand but eight hundred private cars passing through this section of the road. What’s even more maddening is that the surveillance picture of this section of the road is very blurry, and the license plate number can’t be seen clearly.
Li Zhudao and a group of investigators were sitting in the office, staring helplessly at a car flashing across the screen, speechless to the extreme. Knowing that Qin Rongrong and Lan Lan were among them, but unable to find out which car they were in, this helpless feeling was like severe constipation, which made people panic.
Theoretically, the only possibility for Lan Lan's disappearance was to leave in a private car. Everyone knows this.
Handling a case is like looking for a key to open a lock. In the past, there was a lock, but the key could not be found. Now, the key to open the lock has been found, but there are thousands of locks...
Li Zhudao stared intently at the fleeting vehicles in the picture. The images of the endless flow of vehicles kept flooding into his mind: speed...distance...speed...
Li Zhudao suddenly had a flash of inspiration and found a perfect way to screen out the lock:
“The length of the blind spot section is fixed, and it is not very long, only about 50 meters. The speed of vehicles passing through this section is basically the same, which means that the time it takes for each vehicle to pass through this section is basically the same. .”
"One of the cars picked up Lan Lan in the blind spot, which means that the car must have stayed briefly in the blind spot. If the time for each vehicle to pass through this road section is calculated, it will obviously take more time to pass this section. The car along the way should be the car that picked up Lan Lan, and Qin Rongrong should be driving this car."
After a pause, Li Zhudao added: "There is no registered vehicle in Qin Rongrong's name. The car she drove may have come from the wrong way, or it may have been registered in someone else's name."
