The Secret Chamber of the Card Game

At 10:30 p.m., the treatment at the scene was completed, and Liang Ting's body was temporarily taken back to the forensic center by a corpse truck.

Yu Hanjiang used Liang Ting's mobile phone to call her husband Xie Yuan, told Xie Yuan about Liang Ting's accidental death, and asked him to come to the forensic identification center to claim the body.

Xie Yuan thought it was a fraudulent call at first, but refused to believe it. Yu Hanjiang handed the phone to her agent, Sister Chen, and asked her to tell her. Sister Chen choked up and said, "Mr. Xie, it's true, Mrs. Liang, something really happened to her Come on, hurry up and come directly to the police station!"

Xie Yuan was stunned for a moment, and hurriedly said: "Okay, I'll go there now!"

Yu Hanjiang and Xiao Lou followed the corpse truck back to the police force, and Sister Chen was also taken back for detailed interrogation.

Xiao Lou took the evidence brought from the scene to the forensic center for identification, and Yu Hanjiang took Xiao Wu together to interrogate Sister Chen in the interrogation room. The content of the interrogation included Liang Ting's debut experience, her relationship status over the years, and entertainment. The relationship between the stars and so on.

Sister Chen was probably sad, and her eyes were red when she answered: "I don't know her experience in the early years. I signed a contract with Teacher Liang four years ago, and I was her manager... an insider I think highly of her, and I haven't heard of any grievances between her and anyone. She and Xie Yuan also have a very good relationship, and the husband and wife will go on a trip together every year, and the relationship between the two makes people in the circle very envious."

Yu Hanjiang asked Sister Chen to describe in detail the whole day's itinerary today.

Sister Chen said that she went to pick up Liang Ting at home at 06:30 in the afternoon. At that time, Liang Ting was carrying a large bag with a thermos cup inside. Take it with you to drink water when you go out.

On the way, Liang Ting took out a cup and drank a few sips of water. When she arrived at the concert, after putting on makeup and lipstick, drinking water would easily affect her makeup. Therefore, she never drank the water in the thermos until she went on stage.

Yu Hanjiang followed up and asked: "You said earlier that due to constipation, you stayed in the bathroom for more than ten minutes, and when you returned to the lounge, you found Liang Ting's body. During the time you were in the bathroom, what did you hear specifically? Including footsteps , recall carefully."

Sister Chen lowered her head and recalled for a moment, and said: "When I went, I saw three girls from the 505 girl group go to the bathroom together, and I greeted them... I just squatted down for less than half a minute, and the girl next door After going to the toilet, I left, and the voice sounded like Zhao Yuxin."

Yu Hanjiang nodded: "And then?"

Sister Chen thought for a while, and said, "Then, after half a minute, another girl went out, and the bathroom became quiet. After a long time, someone came in again, and knocked on the door opposite, talking softly to someone, specifically what to say I didn't catch it."

Yu Hanjiang looked up at her: "Think carefully, is the sound of the other party's footsteps the sound of high heels stepping on the floor?"

Sister Chen said: "Yes, those who go out and those who come in are all wearing high heels."

Yu Hanjiang wrote down this key in his notebook: "Did anyone else come in during this period?"

Sister Chen shook her head: "No, I didn't hear that."

Yu Hanjiang glanced at the shoes she was wearing—it was a pair of flat sneakers that were convenient for walking.

……

Half an hour later, after Yu Hanjiang had finished interrogating Sister Chen and asked his colleagues to go home from get off work, Xiao Lou came to Yu Hanjiang with the results of the appraisal.

The entire hall was silent, and everyone else had left, only a warm light was shining through the crack of Yu Hanjiang's office door.

Xiao Lou walked over and found that the door of the office was ajar, and Yu Hanjiang was sitting at the desk, staring at the computer screen, crossing his arms thoughtfully.Under the warm light, the dark blue police uniform made the man's side face more handsome, and there was a trace of abstinence from the whole body.

Yu Hanjiang's expression was serious, and he didn't know what he was thinking, his brows were slightly frowned.Hearing the sound of footsteps, he raised his head to meet Xiao Lou's eyes, and his eyes immediately became gentle. He stood up and poured a glass of water for Xiao Lou, and said in a low voice, "Has the appraisal result come out?"

"Well, have all your colleagues gone back?" Xiao Lou leaned against his desk and asked casually.

"They can't help much if they stay. The colleagues in the secret room may give me wrong information and interfere with my judgment. I'll just give them a holiday and check it myself." Yu Hanjiang handed the poured warm water To Xiao Lou, said, "Drink some water."

Xiao Lou took the water cup and handed over the identification results to Yu Hanjiang. He moistened his throat with a sip of water, and then said: "The water in the thermos cup has been identified to be poisonous, and the ingredient is the highly toxic substance potassium cyanide. Judging from the remaining toxins in the water, the dose of potassium cyanide put into the thermos by the murderer should have exceeded 40 grams."

Yu Hanjiang picked up the documents and looked down carefully.

Xiao Lou added: "Usually, the lethal dose of potassium cyanide is 0.3 grams per kilogram of body weight. Liang Ting weighs less than 50 kilograms. As long as 15 grams of potassium cyanide is enough to kill her. However, the dose administered by the murderer is 40 grams, seriously exceeding the standard, apparently to make Liang Ting fall into a coma within a few seconds after ingesting the poison and die quickly, before being sent to the hospital for emergency treatment."

Yu Hanjiang nodded: "An excess dose can kill Liang Ting in one go, avoiding future troubles. The murderer seems to know the poison of potassium cyanide very well, and he is determined not to let Liang Ting have a chance of surviving." He turned to Next page, then ask: "Where is the mineral water?"

Xiao Lou replied: "There is nothing abnormal about the mineral water. No toxins were found in all lipsticks, foundations and other cosmetics."

Yu Hanjiang had a "sure enough" expression on his face: "Have fingerprints been detected on the thermos cup?"

Xiao Lou sighed helplessly, and said: "The murderer was very cautious. He should have worn gloves when touching the cup. Only Liang Ting's fingerprints were found on the body and lid of the thermos cup. In addition, I also After careful inspection, there was no scar. This is a typical poisoning case, the dose of potassium cyanide is too large, it can make people unconscious in a few seconds, and Liang Ting didn't even have time to struggle and call for help before she died."

The appraisal result was within Yu Hanjiang's expectations.

The murderer committed the crime this time, obviously premeditated.

He flipped through Sister Chen's interrogation record, pointed it to Xiao Lou, and said, "Liang Ting's cup was brought from home, but she drank the water in the thermos on the way to the concert, and nothing happened. , indicating that the murderer was not her husband Xie Yuan, and there was no poison in her cup at the beginning. Our speculation is completely correct, the murderer was the poison that was temporarily injected in the backstage of the concert."

Seeing that Xiao Lou was listening carefully, Yu Hanjiang continued: "Liang Ting stayed in the dressing room before she went on stage. Many people can confirm this. At that time, there were three people following her, the stylist, the makeup artist, and the agent. It was very difficult for the murderer." Do it under the watchful eyes of everyone. Liang Ting went on stage to sing, stepped down to sign for everyone, and then went to Ye Qi to sing on stage. During this period of about ten minutes, there was no one in the dressing room."

Xiao Lou agreed: That is to say, "The murderer sneaked into the dressing room during this time period to inject poison. During the interrogation just now, several people went out during this time period, and the murderer was among them, right? "

Yu Hanjiang moved a stool over to let Xiao Lou sit down, opened the record book of today's interrogation, and analyzed page by page——

"Zhao Yuxin, she said she went to the bathroom to urinate and went back to the rest room quickly. She was the first person to leave the bathroom. No one knew what she did after she went out. If she just pretended to go to the bathroom and went into the bathroom After taking a shower, come out immediately, then secretly go to Liang Ting's lounge to inject poison, and then return to her own lounge, there is no time left."

"Ye Lan, she forgot to bring toilet paper to the toilet. This is her unilateral statement. Did she really forget to bring it, or did she find an excuse to distract her companions and sneak out of the bathroom to poison Liang Ting? Sister Chen added The confession can prove that Ye Lan really forgot to bring the toilet paper. Because at that time, Sister Chen was also constipated and squatting in the bathroom, she heard Liu Xi's footsteps leaving and coming back, and she also heard Liu Xi knocking on the door to hand Ye Lan a tissue."

"Liu Xi spent seven or eight minutes looking for tissues, which is a bit suspicious. But Ye Lan is the most suspicious." Yu Hanjiang circled all the suspicious points of the three people's testimony with a pen, and looked at Xiao Lou: "Ye Lan lied .”

Xiao Lou took the interrogation book and checked it carefully.

Ye Lan said: "It seems that someone came in, maybe it was a makeup artist or a staff member. The footsteps I heard were not Liu Xi, because our second outfit was high-heeled shoes, and that person was wearing flat shoes."

Sister Chen's testimony mentioned that there were three footsteps during the process.The first time, a person went out, and that person was Zhao Yuxin who went to the bathroom the fastest; the second time, another person went out, and it was Liu Xi who went to help Ye Lan find tissues; the third time, a person came in and knocked door, and there was a deliberate soft voice, it should be Liu Xi knocking on Ye Lan's door and handing a tissue.

Several members of the girl group, because the second outfit is high-heeled shoes, the sound of footsteps on the floor tiles will be very obvious, which is completely different from the sound of flat shoes on the ground.Sister Chen squatted there, it was impossible not to hear the footsteps of the fourth person.

Ye Lan said she heard it, and Sister Chen said she didn't hear it. The two testimonies were contradictory, and one of them must be lying.

Why is Ye Lan lying?

Yu Hanjiang explained: "Because of the four people who went to the bathroom, only Sister Chen wore flat shoes. If Ye Lan really heard the sound of flat shoes stepping on the floor, she should have heard Sister Chen walking out of the bathroom sound, not the sound of someone walking in."

Looking at Ye Lan's testimony, Xiao Lou suddenly realized: "She was indeed lying. Only Zhao Yuxin, Ye Lan, Liu Xi, and Sister Chen went to the bathroom at that time, and the others all had companions who proved that they had never been to the bathroom ...If Ye Lan really heard the sound of flat shoes stepping on the floor, it should be Sister Chen walking out, not someone walking in."

Walking in and going out, the footsteps are different.

Ye Lan said the opposite in a panic, which indirectly proved that Sister Chen's testimony was correct.

Why did Ye Lan lie?
