Back at the police station, Team Xiao interrogated Song Ke: "It's still the same question, why did you run away?" ”

Song Ke didn't speak: "I only talk to my lawyer." ”

Team Xiao ignored the attitude of the suspect in the storefront and continued to ask, "Where is Du Ting?" ”

Song Ke closed his mouth and didn't speak. At this time, Song Ke's lawyer arrived, and his lawyer sat next to him and said to Team Xiao: "I'm sorry, from now on, my client will not answer any of your questions now. ”

A sneer flashed in Song Ke's eyes, he must have felt that we didn't have any evidence to prove his guilt.

Li Jing pulled me: "Xiaozhi, don't you think it's a little strange?" ”

"What's wrong?" I'm still in a state of anger.

Li Jing pondered for a moment: "He has already found a lawyer for himself, and the reason why he can smile so proudly shows that he has a perfect alibi, and in some kind of Cheng dù, his alibi can even deceive the lawyer's eyes." ”

"But the more perfect the alibi, the more doubtful it is, and that's what you told me." I smirked.

Li Jing looked at me funny: "Yes, so let's start checking again now." ”

Typing in 'Song Ke', there is nothing worth noting except for basic identity information.

"Can't find any other information?" Li Jing asked Shi Hao.

Shi Hao shook his head, it was a police officer knocking on the door and coming in: "Professor Fang, Team Xiao asked me to send this information to you." Team Xiao said that this was Song Ke's alibi, and asked Professor Fang to check the authenticity. ”

When we opened the information, it was Song Ke's confession to the police accompanied by his lawyer.

"On the day of Du Ting's disappearance, Song Ke received customers in the store all day, a perfect alibi." Shi Hao shrugged his shoulders after reading the report, "However, we can still verify the authenticity of the alibi." ”

"Surveillance footage?" Li Jing confirmed with him.

Shi Hao tapped on the keyboard, and a map appeared on the screen, and Shi Hao planned the route of the map: "That's right." Even if you stay in the store all day, there is always a time to rest. The store's surveillance is turned on as long as the power is uninterrupted, and the building does not supply electricity until 9 o'clock in the morning. Du Ting went to work at 9 o'clock, and according to his brother's description, Du Ting left home at 7:30, and the time from Du Ting's house to the company only took about 40 minutes. According to Du Ting's brother's description, Du Ting had the habit of eating breakfast at home, but on the day of her disappearance, she was in a hurry to go to the company and didn't even eat breakfast. But if you eat breakfast at half past 7 o'clock, even if you have half an hour to eat breakfast, you will definitely not be late when you leave to arrive at the company at 8 o'clock, not to mention the traffic jam on the road, Du Ting takes the subway to work, Du Ting's home is in the city center, but the place of work is outside the city, and there will be no possibility of squeezing the subway. From this, we can speculate that the reason why Du Ting left the house at half past seven is that she still needs to go to other places before going to work, so let's calculate, if Du Ting goes to the Star Ring Plaza before going to the company, then she will waste 15 minutes first, and it takes more than 50 minutes from the Star Ring Plaza to the company, which can just explain why she is in a hurry to go out. We now know that the gambling hall did not go to the company that day, so her disappearance time was before 9 o'clock, and according to the current inference, her disappearance time can even be advanced to 8 o'clock. Then let's take a look at Ou Qida's monitoring opening time, the building is powered at 9 o'clock in the morning, Ou Qida's in-store monitoring starts work at 9 o'clock, and employees arrive at 9:30 one after another, Song Ke arrived at the company at 9:40, so from 7:30 to 9:40, this is nearly 2 hours of blank time, and he has not provided an alibi. Shi Hao turned around triumphantly.

Li Jing grinned: "Thank you." Xiaozhi, we should ask Song Ke what he was doing in this blank time? ”

Song Ke, accompanied by his lawyer, entered the interrogation room again, this time with Li Jing on the jury.

Team Xiao looked at Song Ke and asked, "Your alibi seems to have been prepared in advance, but I still want to know where you were before 7 o'clock to 9:30 o'clock that day?" ”

Song Ke didn't panic, he glanced at the lawyer, and the lawyer replied on his behalf: "Just now my client has already told you about his itinerary for the day, I think there should be no doubts, right?" ”

Team Xiao looked at the lawyer: "But his alibi doesn't include the blank time period I just asked." ”

Song Ke whispered in the lawyer's ear, and the lawyer replied, "My person was on his way to work at the time. You can view it on the CCTV footage of the public system. ”

"What kind of transportation are you taking?" Team Xiao asked.

Song Ke smiled: "Bus." ”

Team Xiao knew the meaning of his smile, except that there was no video in the bus at the intersection. He can only be sure that he was filmed at the intersection, and if the timing is right, public footage can also provide an alibi. Team Xiao secretly gritted his teeth, and Li Jing didn't expect Song Ke to keep such a hand.

Shi Hao and I stared at the monitoring of the interrogation room, and Shi Hao and I said, "Brother Shi Hao, can you help check the time when Song Ke's family arrived at the Star Ring Plaza." ”

"It's one and a half hours by bus. But. Shi Hao tapped on the keyboard, "However, in the public video that day, Song Ke got on the bus at 7 o'clock, but the time he arrived at the Star Ring Square was 9:35, two and a half hours." The No. 52 bus he took was unmonitored on Wutong Road. He could have gotten off at Wutong Road and took another bus to the company after committing the crime. And Wutong Road is only one street away from Du Ting's house. ”

"Check the road conditions for the day."

Shi Hao opened the day's traffic information: "Unimpeded." According to the video situation, the license plate number of the bus that Song Ke took for the first time was locked, and after checking it all the way, he should have arrived at the Star Ring Plaza at 8:45, but in fact, according to the video in front of the Star Ring Square, Song Keke was 45 minutes late, and there was evidence that he changed cars halfway. Shi Hao turned up the license plate information on the screen.

I sent the message to Li Jing, who was still in the interrogation room, Li Jing gave the mobile phone to Team Xiao, and the two of them met their eyes, Team Xiao still bit the question at the beginning, and his tone was much more affirmative than just now: "Song Ke, we just finished checking the public video, I still hope you can tell us the truth." ”

Song Ke looked at Team Xiao noncommittally, Team Xiao read the message we sent to Li Jing, and Song Ke's face was obviously not good. Whatever he asked, Song Ke didn't answer. The lawyer requested a private meeting with the client, and Team Xiao took them to another office.

"Looking at Song Ke's reaction, he is definitely related to Du Ting who we are looking for again." I stared at the empty interrogation room and talked to Li Jing.

Li Jing didn't answer, and after a few seconds he asked me, "How long is left?" ”

"Less than 18 hours." I answered him.

"Go to Mr. Lu and see what he thinks." Walking to the door, Li Jing stopped again, "Shi Hao, go and see if there is any place on Wutong Road where you can hide people and it is not easy to arouse suspicion." Also, see if Wutong Road has an intersection with the destinations of the previous victims. ”

Teacher Lu was really reading the previous victim record, and when he saw us coming in, Teacher Lu suddenly asked us, "Have you seen Song Ke's interrogation?" ”

"I'm done. There is a lawyer to protect him, and he is fully able to refute all our evidence. I puffed up.

Teacher Lu smiled: "That's because your investigation is not comprehensive enough." Have you observed his appearance? ”

"Nope." I shook my head: "Does it matter?" ”

Teacher Lu took off his glasses: "Of course it has a relationship." The German psychiatrist Emil Kretschmer once divided people into 4 types, namely the inner embryonic layer type, the middle embryonic layer type, the outer embryonic layer type and the balanced type. Among them, the mesoembryonic type was once considered to be the most common type of juvenile delinquency, because they have more muscles and a more vigorous body than other types, and they are also more adventurous, competitive, aggressive and competitive than other types. However, as the age increases, after having a high IQ crime, the mesoembryonic type does not mean that it is more related to the criminal behavior of adults, on the contrary, in many cases, the offender is an ectoembryonic type of person, this kind of person looks weak and slender, and the artist-like melancholy appearance gives them more opportunities to be loved by women, their minds are very developed, introverted, and even more depressed, and this type of person generally participates in high-IQ crimes. Or plan out how you will face pressure from investigative agencies before committing a crime. They have good looks, they dress decently, they don't commit crimes for their own value, they don't usually make offensive moves, they commit crimes to make up for a certain emptiness in their hearts. Therefore, it is not enough to focus only on the time point of the day of the crime. ”

"So what are we going to do?" Li Jing asked.

Teacher Lu put the glasses back on the bridge of his nose again: "Re-investigate Song Ke." ”

"Did you find anything?" Li Jing asked Shi Hao.

"There's no problem with superficial information." Shi Hao's voice came out of the public release, "Life has always been normal, there is no divorce of parents, and there is no bloody episode of dropping out of school halfway." ”

"Check if his parents' generation has a criminal record." Teacher Lu's voice came from next to me.

Through the phone, the sound of the keyboard tapping "da-da" could be heard, and after a while, Shi Hao replied: "No." Wait a minute, I found something, Song Ke's mother has blood type A, and his father has blood type O, but Song Ke has blood type B. I look at his date of birth, his parents were married when he was three years old. Wait a minute, come to the technical department to find me, I have something for you to see. ”

Immediately there was a busy sound of 'toot' on the phone, and Mr. Lu stood up: "As I said, your previous investigation was not careful, okay, let's go find Shi Hao, I believe he will bring us good news this time." ”
