The campus of the University of Mining is very large, and Da Leizi does not know where the crime scene is, watching some students walking to the north, Da Leizi also drove to the north, and soon saw a six-story building under construction, surrounded by many students, and two police cars parked next to it.

Team Xing, Zhou Peng, Lao Wei, Forensic Doctor Wang, assistant Xiao Liu and others had already arrived, and they didn't see Leng Tong's big beauty, and there were a few teacher-like people who were also surrounding outside the cordon.

When Da Leizi and I came over, Team Xing was turning around, nodding at me, pointing to a dormitory building not too far away and asking the students, "Who are the students in that dormitory building?" ”

"We both are." A female classmate took another classmate's hand and replied, then asked, "What's the matter with you?" ”

"Did you hear anything last night?" Team Xing frowned and asked, "It's about nine to ten o'clock in the evening." ”

"It seems that at nine o'clock, I vaguely heard a terrible scream." The girl groaned for a moment and said, "But we didn't hear it very clearly, and we didn't think about it!" ”

Team Xing nodded and motioned for me to come over too.

The two of us also hurriedly followed, only to see a girl lying on the ground, her long hair was scattered on the ground, and there was a blood stain underneath, and the coagulated blood stuck her hair to the ground, and she couldn't see her face at all, which looked a little scary.

Team Xing came over and asked, "Forensic Doctor Wang, can you be sure whether it was suicide or homicide?" ”

"It's hard to know for sure yet, I'll have to take a closer look." Forensic Doctor Wang replied, and then motioned for Xiao Liu to help turn the body over.

When the girl's body was turned over, everyone suddenly let out an exclamation.

We can all clearly see that among the blood stains under the girl's face, a playing card suddenly appeared!

This playing card is the queen of hearts, soaked in blood, and the hearts also look a little dazzling, a very common thing, at this time it looks so terrifying and weird to us.

Team Xing's face became more and more ugly, he turned his head to look at me, and then said as if muttering: "This should be his killing, my hunch is good, this is a series of serial murders!" ”

At this time, there was a faint scent of roses behind me, and I only heard a cold and crisp voice say: "This is indeed his killing!" ”

In fact, I don't need to hear the voice to know that it is Leng Tong's beautiful woman who is here, and I am very familiar with the unique faint fragrance of this beautiful woman, so I can't help but glance back at Leng Tong.

The scene was still very quiet just now, everyone was shocked by this playing card, Leng Tong's voice was very crisp, not only me, everyone looked here.

Da Leizi was beside me, and when he saw Leng Tong coming, he subconsciously dodged for a while, gave Leng Tong a look, and then pouted and said, "You saw the playing cards, right?" When I saw this playing card, I also knew that he killed it, and I still need to say it? ”

Team Xing didn't say anything about Da Leizi this time, and also looked at Leng Tongtou inquiringly.

"I didn't just say it when I saw the playing cards, you can look at the vertical distance between the victim and the building." Leng Tong's big eyes glanced ahead, and his slightly pointed jaw was also raised, motioning to Da Leizi to take a look, and then said: "If the deceased committed suicide, it would not be so far from the building, do you think the high platform diving?" ”

I really didn't pay attention to the distance problem, and after Leng Tong said this, I couldn't help but nod and said: "Yes, people who commit suicide by jumping off the building are all desperate, and they will not be like diving on a high platform at all, first come to a forward rush, followed by a turn and roll, suicide does not need any difficulty factor!" ”

"That'······ That's hard to say. Da Leizi obviously also felt that there was some truth in what Leng Tong and I said, but he also thought that we had seen the playing cards before saying it, so he pouted and said, "What if everything is lost, and you try to jump?" ”

"You're not bungee jumping too much, are you? Okay, even if you say it's possible. Leng Tong said lightly, and then asked: "Team Xing asked those two students just now, and they said that they heard a terrible scream, how do you explain this?" ”

Since Da Leizi had refuted it, he also pouted his lips at this time and said, "What's so strange about that?" Who doesn't scream when they jump? ”

"Before people commit suicide, they have to go through some mental struggles, and simply put, they are mentally prepared." Leng Tong's big beauty glanced at Da Leizi and said: "Even if there are some out-of-control screams, it is an exclamation, not a terrible scream, you have to distinguish this." ”

This time, Da Lei Zi was silent, pouting and retreating to the back, obviously afraid that Leng Tong would ask him again, and if he was stunned by the questioning for a while, Team Xing would definitely scold him.

Forensic Doctor Wang nodded and said: "Team Xing, what Xiao Leng said is right, I was busy looking at the corpse at first, and I really missed these two points, the corpse is too far away from the building is a problem, this building under construction is always about fifty meters away from the dormitory building over there, even if the noise is low in the middle of the night, it is heard from such a distance, and it is not a normal reaction of a person who predicts that he is about to die." ”

Team Xing nodded, looked at the two of us again and said, "Whether there are playing cards or not, this attitude of analysis and reasoning is still very good, this case can basically be determined, and he also killed him." Judging from the reappearance of the playing cards, the two victims before and after, although one is outside the school and the other is inside the school, the murderer must be a person. ”

I also nodded and said: "It seems that the murderer we speculated yesterday is also a good character, he came down to put the playing cards under the murderer's body after killing someone upstairs, the night is very quiet, he knows that the victim's screams may attract people, and he dares to do this." ”

When Team Xing heard me mention playing cards, he immediately turned his head and asked the two of us: "By the way, this time it is the Q of hearts that appeared on the scene, what do you two think of playing cards?" ”

I looked at Leng Tong and didn't mean anything, so I said: "This is brought by the murderer, your hunch yesterday is right, this is a serial murder case, as for whether there will be a J of hearts next, I can't be sure, but it is certain that the victim Liang Dong the day before yesterday must have a connection with this victim." ”

Leng Tong's big beauty said with a puzzled face at this time: "When playing poker, under normal circumstances, A is bigger than K, and the playing cards left at the scene of the victim's death started with K, which is a little strange?" ”

Team Xing was also stunned when he heard this, but quickly nodded and said, "By the way, before you came, I also asked about some information, and the identity of the deceased has been determined." ”

The Xing team came a little earlier than us, and the identity of the victim has been confirmed, it is Tan Jing, a sophomore at the University of Mines, who came out before closing the dormitory building last night and did not return overnight.

In the morning, a little couple came here to chat when they found out, and immediately called the police, just when we arrived, the Xing team was still asking, there were indeed students vaguely heard screams, and the details needed further investigation.

When the Xing team just said this, the police officer who went upstairs to investigate also came down and told the Xing team, and after their careful search, there were no valuable traces left upstairs.

Leng Tong didn't go over, but gave me a look and walked a few steps back.

I hurriedly followed: "Tongtong, when did you come?" What did you find? ”

"I came a little before you, and after a brief look at the scene, I went out into the crowd." Leng Tong walked straight to the dormitory building in front of him, and said, "Let's go find someone now." ”

I was slightly stunned: "Who are you looking for?" ”

"Find a girl named Li Xiaotong first." Leng Tong immediately said: "If there is no progress in her, we will go find a girl named Huang Jing." ”

I was a little dizzy, I didn't speak, I felt that someone was following behind me, when the two of us looked back, or Da Leizi followed, we both looked at each other, ignored him, love to follow it.

Then I asked curiously, "Tongtong, it sounds like a girl's name, do you know them before?" ”

Leng Tong shook his head and said, "I don't know." ”

At this moment, I was completely dizzy, and said in disbelief: "That's amazing, this is a bit beyond the scope of analytical reasoning?" ”

Leng Tong glanced at me, and quickly said: "This is not magic, nor is it analytical reasoning, but belongs to the category of criminal psychology, I have always adhered to this habit, and this is what I have discovered, and it may not be accurate, I will see it later." ”

When I heard this, I was even more curious, and quickly asked, "Tongtong, what is this habit you are talking about?" ”

"This case happened on campus, and it was night, so the murderer is also very likely to be a student." Leng Tong had no reservations about me, and continued: "After the murderer committed the crime, he must have been panicked and uneasy, and it is very likely that he will appear at the scene of the crime afterwards and peep in the crowd. ”

Now I understand, yesterday when Da Leizi and I rushed to the scene of Liang Dong's crime, we saw Leng Tong coming from there, Leng Tong didn't rush over at that time, but glanced around the crowd, and then came over, which may be the habit that Leng Tong has always adhered to.

Thinking of this, I hurriedly asked, "After you came, you were in the crowd, scanning around, and you found clues?" Could the killer be a schoolgirl? ”

"It can't be said that it must be a clue, it can only be said that it is a suspicious point!" Leng Tong shook his head and said, "I'll talk to you in detail in a while." ”

I nodded, and didn't ask again, the three of them came to the door of a girls' dormitory building in front of them, Leng Tong turned to Da Leizi and said, "You go find a female classmate named Li Xiaotong to come down, we have something to ask her." ”

Da Leizi was slightly stunned, and wanted to ask something, but he opened his mouth and didn't ask, so he pouted coldly: "Why don't you let Xiaoxiao look for it?" ”

Although he said so, after saying this, he turned around and walked towards the dormitory building.

I looked at Da Leizi's back, almost didn't laugh, turned my head and asked, "Tongtong, what suspicion did you find in the crowd?" ”

"It's easy to say, I scanned the crowd, and a female classmate hurriedly walked over and called another female classmate away." Leng Tong said beautifully: "And the look on this classmate's face was a little nervous, and the two of them were talking in a low voice, and from time to time they looked back at the scene, and I followed." ”
