Shen Ke hung up the phone.

A picture came to her mind.

The murderer took a comb and combed Lai Gui's hair seriously and carefully, he combed it, sprayed hairspray, and carefully checked it to ensure that not a single broken hair fell out, with a smug and satisfied smile on his face.

He tied a red scarf to Lai Gui and hung him from a tree.

He took a few steps back, looked at the outstretched middle finger with satisfaction, and couldn't help but step forward and straighten out the corner of the suicide note exposed in the pocket of his clothes.

……

"Xiao Qi, you first talk about Jiang Yuan's investigation."

Chen Mo put down the teapot and sat down.

On the first day he met with the four members of the special case team, it was in this room that a video of Zhu Zhumei's murder was played on the projection.

Thinking about it, he couldn't help but look at Zhao Xiaomeng, "It's raining, you live far away, what are you doing here?" The three of them are very rough, and they can't become embroidery needles after a hundred years of grinding! You're a technician, and it's too late to come back tomorrow morning. ”

Qi Huan smiled, and when he saw that Shen Ke was already about to talk back, he immediately lit up the screen.

"Jiang Yuan's interpersonal relationship is relatively simple, she is an online news editor, she works at 7 in the morning and leaves work at 6 o'clock in the evening, and sometimes she will go to work in the company when she receives a call for breaking news."

"I don't have a boyfriend, and I live with my college classmate Li Ling in the Children's Garden Community, which is seven subway stops away from the company. When it's not raining, she takes the bus to the subway station and then rides the subway home. ”

"She is not a native of Nanjiang and has no acquaintances and relatives in the local area. I usually go out early and return late, and I am not very familiar with the residents in the community. According to Li Ling's description, Jiang Yuan is usually quite timid and cautious, a little socially phobic, and does not like to socialize with people very much. ”

Qi Huan said and played a video.

This is a dashcam footage, the rain is very heavy, and the video looks very blurry.

"It was at this intersection that I wanted to piggyback on Jiang Yuan and was refused, and then she got into a taxi. Based on the payment history of her mobile phone, we found the taxi driver and got this picture. ”

In the heavy rain, Jiang Yuan, who was wearing a white dress, was holding a red polka dot umbrella with difficulty, a gust of wind blew, and the small sun umbrella immediately turned over.

Jiang Yuan leaned over and didn't know what to say, and then walked to the co-pilot's side, and when he was about to open the door, he saw a taxi coming behind him with double flashes and reduced speed.

She immediately abandoned the white car and ran towards the taxi, stopping it directly.

By the time the screen got closer, the little white car had already driven away.

The taxi driver's name was Wang Qiao, and according to his description, there was already a little girl in the car at that time. Because he saw that Jiang Yuan's call had not been answered, the passenger in his car happened to be on the way and could take Jiang Yuan to the vicinity of the subway station, so he stopped. ”

"On rainy days, or at night, there are many drivers who will take a person with them like this, so that they can earn double money. The little girl in the car agreed. ”

Wang Qiao often runs around the area, knowing that the Tonghui Bridge will be flooded and cannot be crossed, so as soon as Jiang Yuan got in the car, they said okay and sat down near Lao Niu's grocery store and got off. Jiang Yuan only needs to pass through that alley and go to take the subway. ”

"We contacted another passenger who was on the bus at the time, and this statement was confirmed. Jiang Yuan was killed shortly after getting out of the car. The taxi driver has an alibi, which can rule out suspicion. ”

"Then there is only one possibility left, Jiang Yuan was raided by the murderer in the alley."

After Qi Huan's words were finished, the expressions of everyone present became heavy.

Jiang Yuan was not violated, his property was not lost, there was no personal vendetta, and it was an accident that he was able to get into a taxi...... All these signs indicate that the murderer is most likely a pervert who kills people at will.

"Where's the white car ahead? Has it been investigated? Shen Ke pointed to the car that had become a blurry white shadow in the picture.

Qi Huan shook his head, "The taxi dashcam didn't capture the license plate number, there are too many white cars of this style, and there is no way to track them after merging into the traffic." ”

"You're done, now it's my turn", Shen Ke said, and put the information he found on the big screen.

"This is a case from three years ago, I checked the weather forecast for that day, and it also rained heavily in Nanjiang City on the day of the incident."

Shen Ke's picture is very simple, with only a few keywords.

"Rainy day, Tonghui Road, red scarf, makeup, gestures, strangulation......"

"There are six commonalities between the two cases, and we have reason to believe that there is a connection between the two cases and they can be investigated together. However, Lai Gui's case, like Jiang Yuan's case, has no suspicious suspects around. ”

Shen Ke said, stood up, and walked to the whiteboard next to the big screen, "Let's draw a portrait of the murderer." ”

"First of all, the murderer was an adult male with a tall build. Lai Gui was strangled to death and then hung on a tree, although he was an old man, but he was a little fat, and it took a lot of strength to hang such a dead person up a tree. ”

"Similarly, Jiang Yuan barely had much room to struggle, so he was directly and quickly strangled to death, which also shows that there is a gap in strength between the murderer and her."

Shen Ke's hand moved, and the projection changed into a map, "This is the place of Lai Gui's death and Jiang Yuan's place of death, it can be seen intuitively from the map, it is very close, and they are all in the area of Tonghui Road." ”

"Tonghui Bridge will accumulate water on rainy days, and there is a subway station through that dark alley, and there is no camera near the mouth of the alley...... These things are known only to those who are regularly active in that generation. ”

"So, the murderer worked near Tonghui Road, or lived in that neighborhood, at least he was very familiar with that generation."

"Thirdly, the murderer must have been injured in the past, and the object of the injury was a man who liked to dress up and wear a red scarf. So he dressed up the object he killed in this way. ”

The projection on the big screen turned into a photograph of the scene of the death of the two deceased.

"Now our question is, how did the killer choose his victims."

"Lai Liang is an elderly male, a local; Jiang Yuan is a young woman, a foreigner; The two have not found any intersection at this time, nor do they have any common characteristics in appearance. ”

"Some serial killers in the past will have obvious preferences. For example, it's all young red-haired women, or it's a terminally ill patient, or something else......"

But Lai Liang and Jiang Yuan don't have these characteristics in common, and they look like indiscriminate killings. The murderer is in the dark, we are in the light, and now we know that only the next rainy day, he will kill a third person near Tonghui Road......"

"So I have a bold idea......"

Shen Ke was halfway through his words, but was interrupted by Qi Huan's mobile phone ringtone, and when he picked it up and listened to it, his face changed instantly.

He hung up the phone, looked at Shen Ke, and sighed lightly.

"Not the next rainy day, the third person who was killed, has already appeared. The brothers over there have already locked down the scene, waiting for us to pass. The deceased this time was a high school student who had just finished studying on his own. ”
