part-time profiler

Knock knock, someone knocked on the door.

Yan Yan was immersed in the case at first, but the sudden knock on the door startled him, he turned his head to look, Yan Su was pale, standing by the door with one arm folded, his clear eyes were looking straight at him.

"Boss Yan." Yan Yan suddenly got up, took three steps in two, and asked, "Uncomfortable? Why don't you rest in the car?"

"I'm fine." Yan Su said, looking past him at the file on the desk.

Under the beige table lamp, the dossier was covered with a layer of light gray tulle, and it was scattered around, and the brutal and bloody photos of the scene rushed into the eyes.

Yan Su's voice was very soft: "Do you have information on Du Tianbo's disappearance?"

Yan Yan followed his gaze, looked back, and replied in a deep voice, "Yes, Kezi was carried out of the file room."

"I want to see."

Yan Yan didn't say a word: "OK."

Yan Su sat in front of the desk, without looking at it, pushed the scene photos of the werewolf case a little farther away, and looked through the files of Du Tianbo's case under the beige light.

Yan Yan gently closed the office door, folded his arms, and stood by the door frame, quietly observing the quiet Yan Su.

The scene in the afternoon lingered in his mind, it was the first time Yan Yan saw Yan Su's fearful and timid side: he hugged himself weakly, wishing he could curl up into a shrimp.

Doubt also enveloped Yan Yan.

Where does the sound that is beyond the frequency range of our country's radio stations come from?Why did Yan Su know?

And, what is the meaning of the passage that the voice repeatedly recited?

Finally, Iamback, who is it, who is back?

Yan Su seemed to be very afraid of that voice, and that sentence, Iamback.

When the male's low and hoarse voice sounded, Yan Su's fear was almost visible to the naked eye.

Yan Yan found that his whole body was trembling uncontrollably, and sweat flooded all over his body in an instant.

The light in Yan Su's eyes dimmed instantly.

It was as if thousands of stars were extinguished at the same moment, fell, and fell into the abyss.

Yan Yan had no doubt that it was Yan Su's nightmare.

But Yan Su didn't want to mention it, and Yan Yan didn't want to ask more.

Yan Yan sighed silently, and found that he cared more and more about Yan Su, Yan Yan could see every change in the other party, and take it to heart.

He scratched the back of his head, feeling a strange soreness in his heart.

"Officer Yan." Yan Su called out to him.

"Huh?" Yan Yan stepped forward: "What?"

"I was thinking..." Yan Su paused, and said in a low voice, "Why did you choose Wenxing County?"

"Why did you park the car in Wenxing County and choose Wenxing County as your destination?" Yan Yan looked into his eyes.

Yan Su nodded lightly, and raised doubts: "What is he going to Wenxing County for?"

Yan Yan stretched his five fingers to support the edge of the table, stood beside Yan Su, and guessed: "Looking for someone?"

"Who are you looking for?"

Yan Yan pondered for a moment, then shook his head, not knowing.

In front of Yan Su was a record of the results of the police visits at that time. Everyone in Wenxing County said that they had never seen Du Tianbo in the photo.

"Is it possible..." Yan Su pondered, "I didn't go looking for someone."

Yan Yan raised his eyebrows.

Yan Su suddenly remembered something, opened the surveillance records, the police intercepted a few photos taken by the camera, and the passing vehicle was Du Tianbo's Audi.

Taking the front and rear of Audi's entry and exit service stations as the interval points, Yan Su divided the photos into three rows.

The first row is the monitoring records of driving on the road before entering the expressway service area, a total of six.

The second row is five monitoring screenshots in the service area when driving into the high-speed service area.

The third row is seven screenshots of Audi driving all the way to Longyou City after leaving the high-speed service area.

"Can you see something?" Yan Su turned sideways to look away.

Yan Yan bent down and observed these photos carefully. Yan Su's classification was so organized that he noticed the difference in an instant.

Before entering the service area, Du Tianbo did not pull down the front sun visor of the car, and the camera could capture his face, which was not very clear, but he could see it clearly.

After leaving the service area, Du Tianbo pulled down the sun visor, and the camera could barely capture his chin, which was just a small white spot when viewed from a distance.

"What... can you see?" There was no change before and after, and the sun visor was pulled down.

"This one." Yan Su pointed to the third photo in the third row. In the photo, Du Tianbo looked down at his phone, revealing the brim of his black hat.

"Hat." Yan Yan seemed to sense it, and Yan Su pointed to the first row: "No hat."

"Pull down the sun visor and put on the hat, so his face can't be seen." Yan Su Youyou pointed out.

Du Tianbo covered his face? !

Why?Is it sunscreen? ?He wants to be a delicate pig boy? ?

Yan Su turned his head and tapped on the working computer next to him, opened the browser to search for the weather on June [-] four years ago, it was cloudy, there was no rain, no sun, the humidity was right, it should be a very cool day.

"There's no need to shade the sun." Yan Su said, Yan Yan sat down beside him and took a deep breath.

"Coincidence..." Yan Yan murmured in a daze.

"On purpose." Yan Su said softly but firmly.

Yan Yan nodded: "Why?"

Yan Su turned his head, looked at him, thought for a while, and said, "I don't want to be photographed on the face in the second half of the journey, because I'm afraid people will recognize it."

"Why aren't you afraid in the first half?" Yan Yan asked back.

Yan Su turned his eyes and glanced at the Wenxing County Police Station. As a result, no one had seen or had any impression of Du Tianbo.

Yan Su was stunned, and opened his mouth: "If... Du Tianbo, it is true that he has never been to Wenxing County?"

At that time, the concept of the police handling the case was deeply rooted in the minds, where the car went, where the people went, so they firmly believed that Du Tianbo drove to Wenxing, and the direction of tracing at that time was also a large-scale search in Wenxing County.

So much so that one point is overlooked, if you haven't seen it, it means that you have never been there.

Yan Yan was enlightened: "I changed people. I don't want others to know that the person on the second half of the car is no longer Du Tianbo, so I covered my face! But the person who actually arrived in Wenxing County was not Du Tianbo."

"How can people from Wenxing County meet someone who has never appeared before?"

Yan Su nodded, and lowered his head to scan the second row of photos, implying something: "As for the replacement, it's..."

He stretched out his hand and brushed the surveillance screenshot of the service area: "Over here."

"Can you see anything else?" Yan Yan almost admired Yan Su.

Yan Su looked back: "The answer lies in the details."

Yan Su's observation ability and sensitivity to details made Yan Yan feel ashamed.

Ordinary people are always prone to preconceived ideas, and when they identify a point, they work hard, unable to get out of their bodies to see the overall situation.

This was also one of the reasons why the police who were handling the disappearance case had no clue.

And Yan Su's mastery of a case is like a mathematician breaking down his formula proof process, from one step to the next, carefully considering every derivation symbol.

Chew it up, spit it out, the details are the answer.

Xiao Liu brought two cups of coffee and fruit, pushed open the half-covered office door, and called out in a low voice, "Team Yan, supper."

Yan Su was still looking at the photo, his eyeballs rolled quickly, as if he was calculating in his head, Yan Yan heard him whispering the numbers.

Approximate speed, interval time, distance traveled.

Yan Yan didn't bother him, and quietly walked to Xiao Liu's side, and took coffee and a bag of fruit.

Detective Xiao Liu looked into the office, Yan Yan patted his head: "What are you looking at?"

Xiao Liu chuckled: "Boss Yan is also inside."

"exist."

Xiao Liu rubbed his hands: "Then I can rest assured, with Boss Yan here, it will definitely be no problem to solve the case."

He was wronged and complained: "Brother Yan, the media has blown up my landline and got my family's mobile phone number. If this case is not resolved, I really can't stand it."

"Don't worry." Yan Yan turned his head to look at Yan Su who was focused, and replied in a low voice: "It's coming soon."

Xiao Liu left with hope.

Yan Yan put down the fruit bag, peeled a banana and gave it to Yan Su, but Yan Su waved his hand and refused, so Yan Yan had to enjoy it by himself.

According to the monitoring records of the service station, Du Tianbo's white Audi entered the service station of Ninglong Expressway at around 01:30 noon and left the service station at [-]:[-] pm.

The white Audi stayed in the service area for about 10 minutes.

"Is there a video of the whole process?" Yan Su turned to look at Yan Yan.

Yan Yan gnawed bananas happily, looked down at other materials, wondering if he could find any clues, so he didn't notice the banana dust on his lips.

When Yan Su stretched out his hand, Yan Yan was stunned.

That hand was cold, but its fingertips were soft, and it gently brushed the corner of his lips, wiping away the unsightly minced pulp.

Yan Yan raised his head, his wolf-like eyes fixed on Yan Su.

Yan Su subconsciously took half a step back, as if some hidden danger was approaching.

But soon, the looming danger dissipated.

Yan Yan quickly grabbed the tissues, took three in a row, and grabbed Yan Su's wrist.

That hand has long, slender fingers and well-defined joints, which is probably very suitable for playing the piano.

Yan Yan wiped off the stains on his fingers, lowered his head, and didn't look at Yan Su, but his heart suddenly turned upside down.

Too bad, a sentence suddenly popped up in Officer Yan's mind, it was a feeling of heartbeat.

Officer Yan, the straight man of steel, felt that he had been hit by a huge shock, no less than a magnitude [-] earthquake or a magnitude [-] tsunami. He held Yan Su's hand without moving.

Yan Su moved, and Yan Yan released him as if he had recovered.

"Video." Yan Su's tone was calm, not aware of Comrade Yan Yan's turbulent inner world. He pointed to the photos in the service area: "From twelve o'clock to two o'clock in the afternoon, are there any videos from these three cameras?"

"There should be. I'll call Kezi." Yan Yan strode forward, turned around and went out to the technical investigation office.

After he left, Yan Su lowered his eyes and cast his eyes on the finger that Yan Yan had brushed against. His index finger was slightly bent, and his eyes were deep. After a long time, he sighed softly.

Because of the case of Du Tianbo's disappearance, the videos during this period were all kept in the case file. Soon Zhang Ke recalled the videos, and Yan Yan imported them into his office computer with a USB flash drive.

Yan Su sat in front of the computer desk, clicked on the video with the mouse, and carefully looked at it frame by frame.

After a while, Yan Su raised his head: "Is there a layout map of the monitoring heads of the service station?"

Yan Yan took out a thick stack of documents and handed it to him. Yan Su picked up the floor plan and compared it with the surveillance video.

A few minutes later, Yan Su put down the floor plan, took out a pencil and drew two lines between the three cameras.

This is the track of the white Audi.

Yan Su marked the three cameras with A, B, and C in sequence, and at [-]:[-] p.m., the Audi drove out of the Ninglong Expressway service area from A to C.

"The camera is facing the parking lot. It takes 20 seconds for the Audi to go from the front of A to B." Yan Su said softly.

This can also be seen from the timing on the video.Yan Yan nodded.

"But here." Yan Su pressed pause when Audi passed B, found the video of Audi passing C, and pressed pause as well.

The time difference is 294 seconds, almost 5 minutes.

There is a monitoring blind spot between B and C. It is at the corner of the parking lot. There are utility rooms and garbage stations. Few people park their cars there.

"Short distance of 5 meters, is it necessary to drive for [-] minutes?" Yan Su asked softly.

Yan Yan frowned: "What do you mean, here..."

"Substitution." Yan Su said, raising his head.

Yan Yan stood behind him, with one hand on his hips and the other on the edge of the chair back, and the two looked at each other.

"At the corner on the oblique right, the nearest one is a specialty supermarket, maybe..." Yan Su considered, "You can ask."

"Okay, let's go tomorrow."

This night passed, there should be no one.

Yan Su nodded: "Yeah."

"Shall I take you back to rest first?" Yan Yan asked, Yan Su got up and walked out.

Yan Yan caught up with him, and the two left the city bureau side by side.

After sending Yan Su home, Yan Yan went back to the car, didn't rush to leave, played an old love song from the last century, lit a Marlboro, and the light blue smoke floated faintly under the dim yellow headlights.

Yan Yan stopped at his usual spot, and when he turned his head, he could see the window of Yan Su's living room.

The beige warm lamp was on for about 10 minutes, then turned off, and the narrow room was plunged into darkness.

Yan Yan sat for a while, smoked the second cigarette, crushed the butt out, and drove home.

That night, Yan Yan unexpectedly dreamed of his first love.

Ten years later, he could no longer remember the other person's appearance clearly, and he seemed to be able to reach out his hand vaguely to touch the other's shoulder-length short hair, the chestnut hair was like smooth silk.

He asked, what's your name, what country are you from?

His first love didn't pay any attention to him at all, Yan Yan chased after him, stretched out his arms and patted the opponent's shoulder, and threw him down neatly with an over-the-shoulder throw.

Those beautiful eyes stared at him for a moment, and she went away.

Yan Yan woke up naturally from sleep, rubbed his sore shoulders, and sweat soaked the bed.

For a moment, it seemed to go back to ten years ago, in the hot summer, in the tropical rainforest, Yan Yan grabbed her hand and asked amusedly: "Are you dumb, why don't you talk?"

What else did he say, Yan Yan rubbed the back of his neck, he said...

"You come with me, I will protect you."

There was a dull pain deep in his brain, and Yan Yan gritted his teeth.

He got up from the bed, washed up, and drove to Wanxin Community to pick up Yan Su.

At six o'clock in the morning, the sky just turned white.

Yan Su opened the door with sleepy eyes, Yan Yan watched him rubbing his eyes, and asked slowly, "I'm early?"

"No..." Yan Su took a step back, let Yan Yan in, and pulled on his slippers to go to the bathroom: "I just woke up."

On the way Yan Yan came, he bought some breakfast at a stall, and when Yan Su finished packing, he handed the breakfast to him.

Yan Su carried Xiaolongbao, fried eggs and soy milk, and followed Yan Yan into the car, and the two set off for the service area of ​​Ninglong Expressway.

"Boss Yan." Yan Yan waited for Yan Su to drink the last sip of soy milk before opening his mouth.

"Ok?"

Yan Yan hesitated, and asked in a low voice: "Yesterday, what was that FM radio...?"

Yan Su was stunned, and opened his mouth. After a long time, Youyou asked back: "Do you really want to know?"

Yan Yan turned his head, Yan Su was looking at him, there was something faint in those amber eyes.
