What Zhang Baoliang doesn't know is that medical ventilators generally have a backup power supply. Although this backup power supply cannot provide power when the machine is unexpectedly powered off, it can activate the alarm device when the power is unexpectedly cut off, thus allowing
Doctors are informed of emergencies quickly so they can treat patients in a timely manner.
Zhang Liang was now in such an embarrassing situation. His unintentional act of unplugging the power caused the alarm to be triggered, and the entire room was filled with piercing alarm sounds. Moreover, he estimated that with such a loud sound, people outside the house must have
You can hear it too!
Zhang Badou panicked for a moment and hurriedly pressed the button on the machine to turn it off, but the machine still screamed tirelessly.
Calm down! Be calm! Zhang Baobao forced himself not to listen to the harsh sound, and carefully checked the ventilator again. Soon, he discovered that there was a small red transparent button on the back of the machine. This kind of button is very common.
It was present on some power strips in the past. Zhang Baoba pressed it, and the alarm sound suddenly stopped.
He let out a long breath and felt a cold sweat on his back. This feeling was like a thief entering the owner's house to steal things and triggering the alarm. He knew that the owner was on a business trip and no one was home, but he was still unconsciously afraid and...
Confused.
As soon as he calmed down a little, Zhang Baoyou heard a series of footsteps coming from far and near in the corridor outside. He glanced at the air pipe. At this moment, he didn't have time to study how it was installed. He first tried to unscrew it.
After twisting it, he found that it was not tightened by threads, so he pulled the pipe hard, and the pipe connected to the oxygen supply device was pulled off. It turned out that it was fixed by buckles.
The footsteps were getting closer and closer, and it seemed that they were walking in the direction of the nurse's station. Zhang Baobao rolled the air pipe together hastily. Because it was too long, he couldn't fit it in his pocket, so he had to stuff it into himself.
into his shirt, then pulled his coat to block it, and covered it with his hands to prevent it from falling out.
At this time, it was too late to put the ventilator back in place. Zhang Baojun hurriedly pushed the ventilator under the computer desk with his feet, pushing it as deep as possible. As soon as he took his feet back, the nurse's station
The door was opened.
It was Mrs. Qin who opened the door and came in. Mrs. Qin was also startled. Obviously she did not expect that there would be anyone in the room. When she saw clearly that it was Zhang Baoan, she breathed a sigh of relief.
She was obviously still angry about what happened in the morning, so she said coldly: "What are you doing here?"
Zhang Liang did not expect to meet Mr. Qin at this time, but he responded quickly and immediately replied: "Well, I'm here to apologize. I'm sorry, Mr. Qin. It was my bad attitude this morning. Don't be angry."
Qin Dada snorted coldly and said, "Apologise? I don't think it's necessary. Do you believe your apology? If I remember correctly, this doesn't seem to be the first time!"
Zhang Liang obviously didn't intend to waste any more time here. He laughed dryly and said, "Really, I will definitely not be like this next time. So what, then you go about your business first and I won't disturb you anymore." After that,
Just walked towards the door.
Qin Dada didn't want to stop him and just let him leave. However, the moment the two of them passed each other, Qin Dada suddenly made a confused voice: "Huh?" Zhang Badan's heart suddenly became tense.
The steps stopped unconsciously.
I saw Qin Dada walking straight towards where Zhang Liang was standing just now, walking to the computer table, bending down, and pulling out the ventilator from under the table.
At that moment, Zhang Baoyou felt his head buzzing. He resisted the urge to run away through the door, and then heard Qin Dada say as if talking to himself: "Why is this thing here?
?”
Zhang Badou loudly told himself in his mind: "Don't panic, hold on!" He pretended to be nonchalant and asked, "What is this?"
Qin Dada glanced at him, put the ventilator back to its original place, and then said: "This is the ventilator. You care so much about that old beggar. Didn't you notice when he was wearing it?"
On the surface, Zhang Liangbao replied calmly: "Oh!" But in his heart, it seemed that a huge wave was set off! What was going on? She actually took the initiative to tell me?
As if to confirm, Zhang Liang asked again tentatively: "So, this is the one worn by the old beggar?"
Qin Dada didn't say anything, and just said a cold "hmm".
Zhang Liang had completely calmed down at this time, and his brain began to work at high speed. He knew that if there were no flaws in his subsequent performance, he would probably be able to get many clues he wanted to know from Qin Dada today.
After Zhang Baolian made a decision, he found another chair and sat down, acting as if he was not planning to leave. Then he tried to use his gentlest voice and said: "Sir, didn't you ask me this morning?"
Why do I care so much about the old beggar? I will answer you now, because of this!" As he said that, he raised his injured arm.
Qin Dada didn't understand what Zhang Liang wanted to express. She didn't answer and sat down, waiting quietly for him to continue.
Zhang Liang sighed: "Speaking of which, we have a fate with the old beggar. Because of him, you were kicked and I was stabbed, but no matter what, we all helped him. Really, no matter you
No matter what you think, I really feel like I’ve done something great!”
"But!" Zhang Liang's expression suddenly became sad. He looked at Qin Dada and continued: "After we have paid so much, you told me that the old beggar died in the end. Then tell me what we did.
What's the point? Why did I get stabbed this time?"
Seeing Zhang Liang's somewhat helpless look, Qin Dada still softened her heart. She could no longer make that indifferent expression, and could only say in a soft voice that even she herself was not aware of: "Life and death are determined by destiny.
What we have done is enough. There are some things that are beyond your control and you shouldn't think too much about them. It will only increase your worries."
Zhang Liang nodded and said: "I know, but I may be born with a low life, so I just want to know what happened last night, and how did the old beggar die?" After saying that, he raised his hand and raised his hand.
He started to look at Qin Dada with burning eyes.
Qin Dada looked at Zhang Badai calmly, as if he wanted to see through his innermost thoughts. Zhang Liangbao was actually very nervous now. Now that he had spoken, it was the most critical moment. If Qin Dada still didn't tell him, then
He really had no other choice.
The atmosphere became more and more depressing, and in the end Zhang Liang couldn't help but was about to give up. He was about to get up and find a reason to leave, when Qin Dada spoke.
She still said calmly: "Since you want to know so much about what happened last night,
I'll tell you what happened. Yesterday, I stayed in the old beggar's ward. In the middle of the night, I went out to do other work. When I came back, the other doctors had already rushed over.
, I realized that during the short period of time I was out, the old beggar's condition suddenly worsened and he died. This is the whole story, how about it, is it detailed enough?"
Zhang Liang didn't know how to answer her, and Qin Dada obviously didn't want to get any answer from him, so he just continued to talk to himself: "Originally, this matter was supposed to be regarded as my dereliction of duty. It was Director Bai who reported this to me.
The hospital interceded on my behalf, so I was not punished more seriously. However, I know that many people thought that I deliberately failed to take good care of him because he was a beggar and had no money to pay for medical expenses. Even if he died,
It just saved myself and even the hospital a trouble. However, they never thought about my feelings. That was a person! The person who was living in front of me a minute ago! I just did my part.
Do I want him to die because of his internal work?" At the end of the sentence, Qin Dada's voice was trembling, and she was trying her best to suppress her emotions.
After a while, she raised her head and looked at Zhang Baojun, and asked quietly: "Bao Bao, you also think that I killed the old beggar, right?"
Zhang Liang did not expect that Qin Da would ask him this in the meeting. He hesitated and said in a panic: "How could it be possible? I..."
Qin Dada interrupted him and said: "We should never meet again, and you should not come to me again. Let's just pretend that we don't know each other." After saying that, she stood up and walked towards the door.
Opening the door of the nurse's station, she paused, looked at Zhang Baoan's hand that was covering his chest, and said something a little confusing: "Sometimes, the stomach hurts because there are too many useless things in it.
Stuff!" After saying that, he left without looking back.
Zhang Badian sat there, watching Qin Dada leave, a little dazed. He didn't know what the last words she said meant. In fact, Zhang Badian felt that his whole person was in chaos now. Originally, he thought he could
Daddy Qin found some useful clues, but Daddy Qin's previous words, although he told him what happened last night, made him fall into greater confusion. Daddy Qin's tearful statement made people sad.
I have to believe that she is innocent, but is it really what she said?
Zhang Liang sat for a while, then got up and left. Now he just wanted to go home, lie on the bed, and think about nothing. Although Qin Dada's last words were full of anger, Zhang Liang could feel that she was really serious.
He was angry, or disappointed. At that moment, there seemed to be an invisible rift between the two people. They would never go back to the time when they just met.
Back at the place where he lived, Zhang Baobao sat on the bed and looked at the neat desk that Bai Jingwen had tidied up. On it was the air tube removed from the ventilator. Until now after investigating the matter, he no longer knew what to do.
What should be done next? After all, he is just an ordinary person. Even with these so-called evidences, he does not have the ability to take any measures.
After thinking for a long time, Zhang Baoan finally took out his mobile phone, called up his address book, browsed for a while, and made the second call of the day.
The phone rang several call tones, and soon the call was connected, and a slightly surprised voice came out: "Hello, hello!"
Zhang Liang took a deep breath and said as calmly as possible: "Hello, Officer Li, I'm Zhang Liang." Yes, at this time, Zhang Liang thought that the person he could consult was the one who handled Song Jiao's accident case before.
They also helped them catch the street gangsters, the deputy captain of the criminal police detachment, Li Wenyu.
Li Wenyu obviously didn't expect Zhang Baoan to call him, but he still politely replied: "Oh, Bao Bao, why did you remember to call me? What's the matter?"
Zhang Liangliang suddenly didn't know how to express this. He said with some anxiety: "It's like this. I have something to report to you. I wonder when you have time, can we meet?"
Li Wenyu was a little surprised. He smiled and said, "Why, it's so mysterious? Can't you tell me on the phone?"
Zhang Liangbao said embarrassedly: "I'm afraid I can't explain clearly on the phone. To be honest, I'm a little confused now!"
Li Wenyu thought for a while and then said: "Okay, at 6:30 in the evening, you will be off work by then. Let's meet and talk."
Zhang Liangliang agreed quickly, agreed on a meeting place, and hung up the phone.
In the following time, in order to explain it better later, Zhang Liangliang summarized the recent events in his mind, then found a black plastic bag to put the gas pipe in, and then lay down on the bed to rest.
a while.
Unknowingly, Zhang Hao fell asleep. In fact, it was almost three o'clock when he came back from the hospital, so it wasn't long before the time he agreed with Li Wenyu.
In such a short moment, he had a dream. In the dream, he seemed to be in front of the old beggar's hospital bed. A man was cutting the ventilator's airway with a knife. The old beggar was holding on to the oxygen mask and was in pain.
Struggling, at this moment, the man suddenly turned his head, and it turned out to be Qin Dabao! When Qin Dada saw Zhang Liangliang, her face suddenly changed to an extremely ferocious expression. She took a knife and slashed towards Zhang Liangliang, and Zhang Liangliang shouted.
He made a sound, waving his hands wildly, and suddenly woke up, only to realize that it was a dream!
Zhang Liangliang gasped for breath. He found that since experiencing Song Jiao's car accident, he had nightmares more and more frequently. He didn't know whether this phenomenon was good or bad, or whether it foreshadowed anything. He only knew
, if this continues, I'm afraid I will be driven crazy sooner or later!
He looked at his phone and saw that it was already a quarter past six! Zhang Baobao quickly got out of bed, wiped his face randomly, picked up the bag with the gas tube and ran out.
He didn't drive because it was the rush hour after get off work and the road must be very congested. He stopped a taxi and told the driver to take a shortcut and drive faster. However, when he arrived at the place he agreed with Li Wenyu, he was still nearly twenty years late. minute.
Fortunately, Li Wenyu didn't mean to blame him. Seeing how out of breath he was, he instead ordered him a glass of juice to let him rest.
The place they agreed on was a simple fast food restaurant. Li Wenyu did not immediately ask Zhang Bao Liang why he was looking for him, but ordered two rice bowls first. Zhang Bao Bao didn't eat well at noon, and he spent the afternoon struggling.
When he saw Li Wenyu ordering food, he was not polite and ate happily.
Li Wenyu simply took a few bites and then stopped eating. He didn't suffer from hyperactivity, so he just waited quietly for him to finish. Finally, he swallowed the last bite of the Sanxian Rice Bowl and drank the last sip of juice in the cup.
, Zhang Baojun was satisfied and took a tissue to wipe his mouth.
Li Wenyu looked at Zhang Baoan and felt a little funny. He said, "How are you? Are you not full? Do you want something more?"
Zhang Baoan quickly waved his hand and said sheepishly: "I originally wanted to have dinner with my girlfriend at noon, but something happened and I lost my appetite. Now I feel hungry."
Li Wenyu was also a little curious when he heard it. He asked: "What is more important than dating your girlfriend? Is this why you are looking for me?"
Zhang Liang nodded, pushed the empty plate in front of him aside, and then brought up the black plastic bag.
Of course, Li Wenyu had noticed the black bag a long time ago, but he did not take the initiative to ask, but waited for Zhang Baolan to explain it to him.
Zhang Liang opened the bag and exposed the gas pipe inside. With Li Wenyu's knowledge, he naturally recognized what this thing was at a glance, but he was also more confused as to what Zhang Liang meant by taking out such a thing.
Zhang Bao thought for a while and then began to tell Li Wenyu what happened during this period. He did not mention the corpse in the backyard of the hospital, but started from the time when the old beggar was injured and admitted to the hospital. After all, there was something about the corpse.
, he himself still hasn’t figured out what happened, and besides, that incident has nothing to do with the old beggar’s incident.
Zhang Liang spoke in great detail, including what he learned about the old beggar’s injuries, treatment and hospitalization process, as well as his own findings and speculations. He told Li Wenyu everything, and Li Wenyu also had a playful attitude from the beginning.
Slowly becoming serious.
Soon, Zhang Liang finished speaking. He picked up the cup and wanted to take a drink of water, but found that the cup was already empty.
Li Wenyu picked up the kettle and poured him another glass of water, then picked up the gas pipe and looked at it carefully, pondered for a moment, and then said: "Bad, what you said is indeed somewhat suspicious at present.
But this is not enough to prove that this is definitely a murder case."
Zhang Liang had just taken a sip of water, and when he heard Li Wenyu's words, he asked with some confusion: "Why?"
Li Wenyu explained: "First of all, we can't tell whether the nurse, or Mr. Qin, sabotaged the air pipe artificially; secondly, if according to your speculation, it was really her who deliberately killed someone, then her motive
What is it? Why did she choose to do it at that time last night? Third, if she cut the trachea, how did she do it? I just took a closer look at the crack. The crack was smooth, neat, and very...
It's slim, which is why you can't feel it leaking under normal conditions. I think that unless you hold the two ends of the slit with your hands to open the slit, it may not have any impact on normal use at all.
Impact, and it is impossible to create such a wound with ordinary knives at home or even on the market. Common knives that perform plane cuts cause destructive wounds. In other words, there is no difference between cutting and cutting.
It will never be like this. How could she, a little nurse, have such a strange knife? Fourth, even if all of the above are facts, the police need to pay attention to actual evidence to solve the case. We cannot rely on this alone.
I will arrest people based on these so-called speculations."
Zhang Baoyou was dumbfounded after hearing what Li Wenyu said. He originally thought that even if his investigation was not detailed enough, it would be enough to restore the truth of the matter. However, he did not expect that Li Wenyu just put forward such simple points and turned his previous
All the speculations were suppressed, which made him feel as if he had punched the cotton with a punch.
Zhang Bao thought for a while, but still didn't want to give up. He pointed at the gas pipe and asked, "What about checking the fingerprints on this? Can it be used as evidence?"
Li Wenyu smiled and asked: "Let's not talk about whether there is Qin Dada's fingerprint on it. Even if there is, do you think it is strange that a nurse's fingerprint appears on a medical ventilator? Besides, this machine may not be used by many people.
People have touched it, just like you. When you took this pipe, you also left your fingerprints on it. Are you the murderer?"
After listening to Li Wenyu's words, Zhang Liangliang was like a deflated rubber ball. His momentum suddenly disappeared. The whole afternoon's investigation seemed like a joke. Such a result was unacceptable to Zhang Liangliang no matter what.
Li Wenyu comforted him and said: "There are many things that need to be considered in investigating the case. It is already very good that you can do this. In this way, I will take this gas pipe back and let the appraisal department test it to see if the tool that caused the wound can be determined.
What is it? In fact, judging from the current situation, this may be the only breakthrough."
Zhang Liang nodded, still thinking about the doubts Li Wenyu just mentioned in his mind. Suddenly, he seemed to have thought of something and asked Li Wenyu: "Officer Li, you just said that if the tool that formed this crack is found, what will happen?"
Can it help this case?"
Li Wenyu smiled and said: "We can't call it a case yet, but yes, finding tools will indeed help us judge the nature of this matter."
Zhang Liang's eyes suddenly lit up again, and he said excitedly: "Then if the tool is found, and there are Qin Dada's fingerprints on the tool, can it be concluded that she is the murderer?"
Li Wenyu looked at Zhang Liang with some surprise and said, "You seem to be very sure that it was Qin Dada who killed the old beggar. Do you have any other definite evidence or know anything else?"
Zhang Baoshao shook his head with a guilty conscience. Of course he couldn't say that I also found a corpse and suspected that it was Qin Dada. Not to mention whether it was true or not, the corpse was now missing. If Li Wenyu really investigated
I got up and found out in the end that there was no such thing. I'm afraid I would have thought that Zhang Liang was joking with him from beginning to end. Maybe he would be arrested for disturbing public order in the end. If that were the case, Zhang Liang would
Just hit him to death!
Li Wenyu looked at Zhang Liang's eyes and knew that he had something else to say. However, he did not press Zhang Liang to ask him. Instead, he answered his last question: "The possibility you mentioned needs to be based on reality."
Judging from the situation, if the tool is an item with high public contact, then even if there are fingerprints on it, it may not be evidence of practical value."
Zhang Liang nodded thoughtfully, and Li Wenyu continued: "Besides, if there really is this thing, if I were the murderer, I would have cleaned it up long ago, and I will definitely not keep it and find it."
After Zhang Baoli heard this, he suddenly jumped up from his chair. He seemed to have thought of something. He stood up and ran out. He took out his mobile phone while running. At the same time, he shouted to Li Wenyu who was startled by his actions: "
Officer Li, I will contact you again, and I will treat you to dinner next time!" Before he finished speaking, he had already ran out of the fast food restaurant.
