Profiler 4: Criminal Investigation Team

"Ok."

Lu Yuanli said as if nothing had happened: "Boys should pay attention to safety when they go out. In the first case recently, the deceased was a 16-year-old boy. The second case was a college student who had just grown up. Not bad. Normally speaking, there will be no shortage of people to like. Both of them know that they are dating a man, and it is far less safe than meeting a woman. Especially, it is reasonable to invite the other party to the home where you are alone. It is speculated that this person should be good-looking and eloquent, so it is easier to gain the trust of others."

"Too."

Jiao Yang coughed and said: "If it weren't for the good looks of some people back then, they wouldn't have been able to trick me into his home easily. Then they still wanted to do this to me. If it wasn't for my good physique, say Don't be locked up in the basement long ago..."

"Who said just now that this is talking about serious business?"

Lu Yuanli said as if nothing had happened: "Besides, you have become less palatable now, and you have already entered the ranks of safety, so you don't need to worry too much."

It turns out that this is the so-called, as long as I am not embarrassed, is it someone else who is embarrassed?Jiao Yang sighed and said: "Yuanli, you have been angry for so long, shouldn't it be time to calm down? Give another chance, don't be so serious. Look at the things you did to me before, I don't care It’s just a matter of being angry!”

Lu Yuanli raised his eyebrows to look at him and said, "Writing you in the paper and shooting at me is a matter of the same level, can it be compared?"

"No."

Jiao Yang said helplessly: "But this thing has already happened, and I can't go back through time."

"And, even if you can reverse time and space to go back in time."

Lu Yuanli looked at him calmly and said, "Your choice will not make any changes. Is that right, Team Jiao?"

Jiao Yang paused, feeling that he had nothing to say, so he watched Lu Yuanli walk out of the office and went straight to the conference room.

Ke Luoluo had already put the picture materials of the case three years ago and the two most recent cases into the projector in advance.

Jiao Yang cleared his throat and said, "Professor Lu is an internationally renowned expert in criminal psychology. Many of us here have listened to his lectures, so I won't introduce much. In the past two weeks, there have been two cases in a row. People have shown continuity. Professor Lu has already prepared a profile, and I asked Ke Luoluo to send a copy to each of us. Now I want to hear everyone's opinions, and let's determine a main direction of attack."

Since Lu Yuanli was sitting, several people looked at him.

Lu Yuanli stood up unhurriedly, and took out a metal rod from his pocket.He pulled the two ends and stretched it slowly, only then did everyone realize that what he was holding was a telescopic teaching rod.

Lu Yuanli pointed the tip of the teaching rod at the picture of the last case, "I think the breakthrough should come from this case. Compared with other cases, this time there is an extra process of moving the corpse.

And the more steps the suspect takes, the more the logic of his behavior will be exposed, while leaving more physical traces.The mesh white gauze skirt worn by the deceased is very easy to leave various marks because of the special shape of the fabric. "

Ji Yunfan's latest discovery on the deceased's dress has not yet been written in the report.Jiao Yang just told Lu Yuanli, but the other team members didn't know.

Qiao Sen raised his hand and said, "But Professor Lu, the forensic doctor hasn't found anything on the deceased's clothes."

"That speaks to another problem."

Lu Yuanli said indifferently: "Most of us here are gay men, maybe we don't know it. This lady may understand what I mean. The mesh-like fiber fabric has a very strong adhesion. If the lady Walking casually on the street in this kind of clothing can get caught on a tree branch fence or even a stair railing."

"exactly!"

Ke Luoluo said with lingering fear: "I accidentally lost a bet with a classmate once, and was forced to go out with her lace headband. I was going to collapse wherever I went. A headband only has so much space, not to mention It's such a big skirt!"

Lu Yuanli said: "Therefore, the white gauze skirt worn by the deceased did not have much attachment, most likely because when the suspect moved the body, he covered the outside with a layer, similar to plastic sheeting or rainproof cloth. Also, the tarpaulin should be coated rather than knitted, and then wrapped with something like a blanket to hide people's sight.

This shroud supplies also proved Captain Jiao and Forensic Doctor Ji's speculation about the real crime scene.

Plastic sheeting, rainproof cloth, in addition to being ubiquitous when it comes to marine fishery products, is basically a must.Finding these things naturally became the key to finalizing the case.

Then, let's push back again, how the deceased died this time.

In the previous two cases, after numerous forensic examinations, strangle marks can prove that the deceased were indeed hanged, not strangled.Therefore, at present, everyone is more inclined that the two deceased died while experiencing sexual/suffocating pleasure.

Assuming this is the truth, there is more than one way of suffocation by hanging, there are many.Such as wearing a plastic bag on the head, such as sticking your head into the water.That is to say, the deceased this time probably slipped and fell into the water while experiencing this near-death pleasure, or was pushed into the water by the suspect and drowned.

This water happens to be a seawater environment.He should have some kind of peculiarity, which can easily lead to the exposure of the suspect.Therefore, compared with swaggering and leaving without hesitation before, this time the suspect chose to throw the body with great effort.The particularity of this seawater environment may be due to water quality problems, or it may be because someone saw or knew him during the period. Once the deceased is found at the scene of the crime, the suspect is likely to have nothing to hide and will be exposed immediately. It is necessary to embellish others to deceive others. "

After the meeting ended, Jiao Yang specially arranged a small team to conduct investigations in the direction of the aquarium and breeding sites.

There are two well-known aquariums in Shencheng, but they are fully monitored, with front and rear doors and the environment inside the museum, and there are also security guards patrolling day and night.

And, since it's not yet summer, the hours of operation are 9am-6pm.Judging from the time of death of the deceased, it is unlikely to have been lurking in the aquarium for several hours.In other words, even if the murderer is skilled and daring, it is difficult to find a public place like the aquarium to find excitement.

After re-investigation, the pond where the corpse was dumped had a water flow extending for tens of meters. During this period, there were countless wheels and footprints. The evidence may have been destroyed or polluted.

Then, the main direction of investigation was adjusted to the artificial breeding sites around the place where the corpses were dumped.

There are three artificial breeding sites around, and there are a large number of customer workers and other personnel who need to be checked.

A few days later, on Saturday morning, Jiao Yang was working overtime in the office when he received a call from Wang Fujiang.

On the phone, Wang Fujiang's voice became deeper and deeper, "Captain Jiao, we found another dead person here, you...bring someone over to have a look."

For each additional person found who died from a similar cause, the likelihood of suicide decreased.So far, the possibility of an accident in the case three years ago has infinitely approached zero.Jiao Yang could understand his mood, and immediately said: "Okay, I'll go there now."

When Jiao Yang brought Hou Xiyong, Yu Xiaoguang and forensic doctor Tao Xiaoyu to the scene, he touched his nose involuntarily.

This is a small hotel on the outskirts of Minhang City, the name is very bluffing, the appearance is very vicissitudes, and the security measures are very poor.

However, this perfectly matched Lu Yuanli's previous prediction of where the next case would happen.The scene also has similarities with the previous two cases.

After the few of them entered, they saw that this was a single room with only a dozen square meters. The deceased was hanging from the highest point of the security window on the balcony. He looked tall, even obese, but he was wearing a bright red suspender silk nightdress. She wears black silk heels and black high heels on her feet.The deceased's hands stretched from the shoulders and were bound downwards. Both lower limbs were bound and stretched to the back side by bright red nylon ropes, and connected to the nylon ropes that tied the upper limbs backwards.One side of the body was propped on the bay window of the balcony, and the left side, chest, and abdomen were facing the windows.

The person's weight was estimated to be around 190 kilograms, and several police officers worked together to release him.

Tao Xiaoyu performed an autopsy, and Hou Xiyong and Yu Xiaoguang searched for evidence that might remain in the room.

Jiao Yang called the owner of the hotel, the receptionist, and the waiter over to question him.

The hotel has only the gate and the so-called lobby, each with a symbolic surveillance camera, which is actually closed all year round.

The boss wasn't here at the time, so naturally he couldn't ask anything.

Jiao Yang asked the front desk: "What time did the deceased check in yesterday?"

The front desk held the register and checked it: "The deposit was paid for 8 hours before 12:[-] p.m.."

Jiao Yang asked: "Have you registered with your ID card according to the regulations?"

"Registered, registered!"

The boss immediately nodded and said, "We strictly follow the government's regulations!"

Jiao Yang took the ID card handed over by the front desk, and saw that the deceased was Lin Xucheng, 26 years old, a migrant worker.

Jiao Yang turned his head and asked the waiter, "Were you the first to discover the deceased?"

The waiter was an older lady in her 40s, she still seemed to have lingering fears, and she said in a trembling voice, "I found it with Xiaoqian. Xiaoqian asked me to come and have a look at 302 when it was time. I called the door and there was no one." In response, we felt that something was wrong, so we brought a spare room card. Just... we saw him hanging there with his tongue sticking out. We saw that he was already dead, so we didn't dare to go forward, so we quickly called the police. "

At this time, Tao Xiaoyu had already done the preliminary post-mortem work, and Hou Xiyong and Yu Xiaoguang had gained a lot. The toilet paper used on the bed, condoms, snacks, and cigarette butts were thrown all over the floor.

However, it is still hard to say whether the rooms in this hotel are so dirty and messy that they belonged to the deceased and the suspect.

Jiao Yang made a phone call back and asked Ke Luoluo to investigate the ID card of the deceased, and then walked to Tao Xiaoyu's side.

Tao Xiaoyu nodded, and said: "The deceased was about 185 centimeters tall and weighed 190-200 kilograms. It can be said that he was a burly figure. He died of physical/positional/suffocation, and the death time was 10-12 hours. The shoulders, back and hands of the deceased The rope is a common back binding method, and the binding method is very professional, but the rope tied on the feet is relatively rough."

Jiao Yang pondered: "In other words, it is basically certain that there are two people at the scene?"
