Nurse Yu came to the living room anxiously, as if she was about to be judged under the gaze of everyone.
Jian Jing took the initiative to give up her seat, asked her to sit down, and handed her a cup of hot tea: "Don't be nervous, just tell the truth."
Nurse Yu nodded.
Jian Jing asked: "On the day of the incident, at 3:20 in the morning, the monitor alarm sounded. You woke up. What did you do?"
"I immediately performed CPR on the patient." Nurse Yu answered quickly.
Jian Jing: "How was the chairman's health at that time? Was he stiff? Was he cold?"
Nurse Yu tried to recall for a moment and apologized, "I was very nervous at the time and was looking at the electrocardiogram. I didn't pay close attention to what you said."
"So, if your body temperature is cold and your neck is slightly stiff, you won't be able to detect it?"
Nurse Yu hesitated for a moment and said, "That should be the case. I performed CPR through his clothes and didn't touch his skin much."
"Were you closing your eyes at the time?"
"Yes."
Jian Jing then said, "Let me explain. I've said before that rigor mortis will not set in until 1-3 hours after death, and the body temperature is even more subtle. Within 10 hours after death, it drops by about 1°C every hour. Because the eyes are closed, the cornea is cloudy and it is difficult to judge in time."
Jiang Baiyan said: "So, the chairman didn't die at around 3 o'clock?"
She corrected: "No, it only proves that slight discrepancies in the time of death are not impossible."
"What's the point of this?" Jiang Lian asked.
"Please be patient." Jian Jing continued to ask, "Nurse Yu, you vaguely heard some noises while you were half asleep and half awake, right?"
Nurse Yu expressed cautiously: "I'm not sure, but it seems to be the case."
"Did you hear the glass breaking?"
She thought about it carefully and shook her head: "It seems not."
"Okay, you can go back now." Jian Jing said, "Next, let's sort out everyone's testimony."
She flipped through her notebook and said slowly, "Jiang Ou entered the chairman's room at around 12:20, and then Jiang Xue entered at around 12:30 out of curiosity. After about 5 minutes, she left in a hurry. At that time, Jiang Xue mistakenly thought that the chairman had died, and was very panicked and anxious, so she went to find Mrs. Jiang. Is that right?"
This was the result of the (tearing) meeting (x) held two days ago, and it has temporarily received unanimous approval from everyone.
"Okay, I want to ask you two, when you entered the room, did you find any broken glass and liquid on the floor?" Jian Jing asked.
Jiang Ou said: "I didn't see it."
Jiang Xue also said: "I didn't notice it, so I guess not."
"But at around 3 o'clock, there were broken glass on the ground, right?" she asked for confirmation.
Jiang Baiyan nodded: "Yes, I remember there was broken glass on the ground, next to the chest of drawers at the door."
Jian Jing smiled and said, "Considering the relationship between Jiang Ou and Jiang Xue, I think the things they denied at the time should be more credible."
No one refuted.
"So, at least at 12:30, the medicine bottle hadn't broken. In other words, someone else had entered the room during the nearly three hours from 12:30 to 3:20." Jian Jing asked, "Who was this person? Is anyone willing to admit it?"
Still no one spoke.
"Okay, let's put this aside. I have another testimony here, saying that at about 12:30, when Jiang Xue entered the room, Jiang Lian was on the first floor courtyard making a phone call. Is that true?"
Jiang Lian hesitated and nodded: "Yes, I talked to my husband on the phone."
"Show me your video," she said.
Jiang Lian went upstairs to get the laptop and opened the video file. There was a clear recording time on it, starting at 12:50 and lasting until after 3:00 in the morning. Both parties were arguing fiercely about something.
Jian Jing glanced at Jiang Lian. She looked relaxed, as if she thought she was no longer a suspect.
He looked at Jiang Qi again, frowning slightly, as if feeling uneasy and doubtful.
Jiang Ou was a little anxious and kept changing his posture.
Mrs. Jiang put her arm around Jiang Xue's shoulders, seemingly to support and comfort her.
"It seems that the matter is very clear." Jian Jing said, "The video confirms my guess. You are the first person to enter the chairman's room."
Jiang Lian immediately retorted: "Nonsense, do you have any evidence? Who saw me go in?"
Jian Jing smiled and stretched her body: "Indeed, what I am about to say has basically no evidence, it is all my wishful thinking, but - what's the harm in listening to it, right?"
Jiang Lian said coldly: "I don't want to waste time."
"You can choose not to listen, but you will." Jian Jing did not take it as an offense and continued, "At 9:45 p.m. the night before the incident, you had a conflict with your father, and he threatened to cancel your shares in the group. So after you left, you became more and more scared and decided to stop it."
Jiang Lian stood up suddenly, her lips trembling, her voice sharp: "What benefit did Jiang Baiyan give you? Why do you want to accuse me like this?"
Jiang Baiyan leaned his head and sighed sadly: "It's been a few days, can't you see my status?"
"I didn't frame you. Of all the people, you are the one in the greatest danger."
Jian Jing analyzed slowly: "Jiang Qi had conflicts with his father because of his marriage, but it's over. Jiang Ou wanted the shares of the water company - the dispute Jiang Xue heard was about you, right? - but the chairman's attitude was clear, he would not give it to you, so dying early would be disadvantageous to him, and he would not have the opportunity to convince his father.
"Only you. Jiangshui Group was originally to be handed over to you, but your father didn't like your husband, and you were unwilling to give up. Moreover, only Jiangshui Group, which the chairman regarded as his heart and soul, would allow him to change his will at the moment of his death."
She was very sure: "So, you know in your heart that the chairman is going to change his will the next day, which will definitely be disadvantageous to you, and this is the company founded by your mother and her daughter, you are even more afraid that it will fall into the hands of Mrs. Jiang and her daughter, so you must find a way to stop it.
"It just so happens that you know that Dr. Tao prescribed morphine for me, and maybe he explained the dosage to you, and you remembered it, and you wanted to use this method to shut him up."
Jiang Xue stood up impatiently and said loudly: "It's you."
"That's too early." Jiang Ou said unhappily, "Even if you unplug the monitor as you said before, Jiang Xue will definitely find that the screen is not lit when she goes in."
"Just be patient." Jian Jing remained motionless and continued, "You took action, but you regretted it, right?"
Jiang Lian pursed her lips, her face pale, but she said nothing.
"Did you inject one or two? Anyway, not long after, you regretted it, stopped, left in a hurry, and called your husband in the yard, saying that you were possessed by the devil. Your father was so good to you, raising you and nurturing you, but you wanted to kill him. But the matter was done, and you were lucky enough to think that your father would be fine, so you went back to your room and pretended that nothing had happened."
The living room was silent, and everyone had different expressions.
Jian Jing smiled slightly and slowly revealed the follow-up: "The second one is Jiang Ou. I guess you didn't go to him to discuss things, but to get something - a cell phone, or a camera?"
The river gull closed its mouth tightly, like a clam shell.
"Why would you do this? Because you have no idea. Jiang Lian works for the group, and the contents of the will are probably related to this. Jiang Qi established the communication system, so it should also be his. You are the only one who has never done anything. How much the chairman gives you depends entirely on luck. Your competitors are Jiang Baiyan, Jiang Xue, and Mrs. Jiang. There is too much uncertainty."
Just as Jian Jing had said to Jiang Baiyan before, the key to reasoning in this case lies in everyone's mental state.
She carefully analyzed Jiang Ou's motives: "So, in order to take the initiative, you used a trick to install a camera in your father's bedroom and eavesdrop on his conversations with other people."
Jiang Xue and her daughter stared at him coldly.
"But you saw something terrible - your eldest sister was murdering your father." Jian Jing said, "You must have been frightened after watching the video, but the relationship between you three siblings is very close. Your first reaction was to protect your sister. However, you were not capable enough to handle this matter, so you had to go to Jiang Qi."
Jiang Ou said: "Whatever you say, I won't admit it anyway."
Jian Jing was immersed in the most joyful moment of the detective. She waved her hand tolerantly and said, "Okay, the second one is over. Let's talk about the third person, Jiang Xue."
Her eyes widened: "What does it have to do with me?"
"Of course." Jian Jing curled her lips. "When you entered the room, the chairman must have felt a little uncomfortable and looked like he was about to die. And you have always been very brave, and the chairman loves you very much. Maybe you wanted to get closer to see if he was really going to die. Or maybe you knew about the safe and wanted to open it to take a peek..."
Jiang Xue's face suddenly turned red.
"Then, something you never expected happened - the chairman woke up." Jian Jing gave the answer and was satisfied to see the other people's faces change.
She looked like a child who had pulled off a successful prank, and added with a smile, "Of course, it's also possible that he looked awake. Anyway, you were scared and ran away."
The reason why Jiang Xue left in a hurry is a key to this case.
Modifying the will would be disadvantageous to Jiang Lian, but beneficial to them and their daughter. Therefore, when Jiang Xue entered the room on the night of the incident, she definitely did not have any murderous intentions.
So why was she panicking
It is possible that the chairman was dying, but this was inconsistent with the time of death. Moreover, Jiang Xue didn't know why she didn't wake up Nurse Yu immediately to rescue her father.
The fact that she didn't dare to speak out proves that the situation has changed drastically.
The only person who can completely turn Jiang Xue's situation around is the chairman.
"What would happen if your father saw you stealing the will, or in other words, misunderstood you as committing murder?" Jian Jing described Jiang Xue's feelings vividly. "The answer is beyond doubt, you lose your inheritance rights. You immediately found your mother and told her the whole story - Mrs. Jiang, you are next."
Mrs. Jiang looked indifferent.
"You know very well that you won't get much from the chairman, so you must protect your daughter's inheritance rights at all costs. You are not afraid of killing people for this."
Jian Jing's speech speed gradually increased: "You arrived at the crime scene around 1 o'clock - I actually doubt it, Jiang Lian, did you really see her? Not necessarily, going downstairs from your room, it seems that you didn't pass by - Jiang Qi, you guessed it, right?"
Jiang Qi glanced at her, neither admitting nor denying.
"Mrs. Jiang, when you entered the scene, was the chairman awake? Or was he unconscious?" Jian Jing asked, but she didn't need an answer. She just kept talking, "It doesn't matter. You have to do something, but you're an accountant and don't understand medical instruments. If you make a mistake and sound the alarm, waking up Nurse Yu, things will be very bad. The simplest and most effective way is to cut off the power supply to the room."
She spread her hands and said, "That's it. The oxygen tube and the monitor are useless. You know he will definitely die tonight. My daughter's inheritance rights are saved."
The scene was silent.
"The last one, Jiang Qi. You know what your sister did, so of course you have to cover it up for her. The best way is to put the blame on your enemy and make him lose the inheritance right. In this way, no matter which of you three siblings holds the shares, it won't be considered a disappointment to mother."
Jian Jing looked at Jiang Qi: "You made an internal system for Jiangshui Group, and Mrs. Jiang worked in the group. Now all companies need to enter fingerprints. That's how you got the fingerprint of her right index finger - there was only this one fingerprint, otherwise it would be more perfect with the thumb - then, you used a 3D printer to print out the fingerprint, entered my father's room, opened the safe, and left her fingerprint.
"I guess if I hadn't found the safe, you would have led Lawyer Li to find it, right?"
Jiang Qi had to speak up: "Miss Jian, you are very smart, I underestimated you."
"It's not time to praise me yet." Jian Jing made a pause gesture, "It should be because you restored the power supply that you arrived at the scene after the first alarm, but there is still a loophole here."
She looked around at everyone and smiled: "Who broke the medicine bottle?"
