Conan Super Detective

Afterwards, even if the individual interrogation was concluded, the search on the scene there was also ended.

"Master Dongma, the ward at the crime scene and the surrounding area have been searched and no containers or bags capable of storing drugs have been found." Xiaoyehui reported._

"That is to say, the possibility of being taken outside to destroy by the prisoner is not non-existent." Kogoro nodded and said nonsense.

"In addition, we also tested the red herbal tea on the ground, and no toxic reaction was detected in it." Ono said something surprising.

"How do you poison it?" Miwako asked suspiciously.

"About this point, we detected the toxin reaction on the edge of the teacup, which happened to be the place where the lipstick mark appeared." Ono said the inspection report from the gunfield.

"So, it should be that when Ms. Xudong was drinking tea, her mouth touched the edge of the cup, and then mixed with herbal tea to drink the poison together." Ono continued to add his own judgment.

Of course, there should be nothing wrong with this judgment.

"In other words, do you still think that someone among us applied poison to the cup before she drank that sip of herbal tea?" Beppu asked dissatisfiedly.

"So, if you do that, someone will definitely notice it!" Bafang dissatisfied.

"We haven't seen anyone make such a move at all," Takasaka said affirmatively.

"So, didn't Amuro-kun just said that? Someone smeared poison on his cup, and then secretly exchanged his cup with the victim's cup when everyone was not paying attention!" Kogoro said.

"I also said that this is impossible! The four of us drank yellow chamomile, brown peppermint, and blue butterfly peas, while Lingnai drank red roselle. People inadvertently exchange cups, no matter how much they concentrate on other places, they will immediately react to something wrong?!" Beppu emphasized.

"But only the victim added a slice of lemon to his tea, right? If the area is such a large area, how much can cover most of the water surface, if you don't pay attention, maybe you can't see it at all?" Kogoro again Said.

Of course, his statement was rather nonsensical, so he was immediately refuted by the three of them and was speechless.

"Okay, okay, everyone calm down." Miwako quickly interrupted the meaningless quarrel.

"In short, what can be determined now is that the cup is coated with poison, and the prisoner can only use the poison at the tea party, so the prisoner can only be one of the three of you. Next, because no poison was found in the entire ward. The container or bag, so we judged that it should be taken out of the room by the prisoner." Miwako said slowly.

"Because Master Touma arrived and sealed off the scene at the first time, the prisoners should only be the Beppu ladies and the Bafang ladies who left the ward halfway." Mikako said solemnly.

"Well, anyway, as long as you investigate the drain in the toilet and the road to the convenience store where you can buy refreshments, you should be able to find something that can serve as clues and evidence." Kogoro nodded and said smugly.

"But don't you think that if they are prisoners, are they too bold?" Dong Ma said with a smile suddenly.

Chapter 1757 The Murder at the Hospital Tea Party (5) First

"Bold? How do you say this?" Miwako asked suspiciously.

"If the prisoner wants to put poison on the teacup, then it is absolutely impossible to let the teacup leave his field of vision, because if someone else cleans the teacup without authorization during his absence, his efforts will be lost. Even worse. The situation is that if the color of the poisonous teacup and the black tea in it is changed, you may be in danger of being poisoned. After all, the murderer himself needs to drink tea during the whole process, even if he is careful, he still needs to drink it." Dongma shook his head and denied it. Kogoro's reasoning.

"But in this way, how did the prisoner poison it? And where did the container containing the poison be placed?" Ono asked continuously.

"In this way, I can only continue to search this ward." Miwako said with a headache.

"No, I don't think this is necessary." Dongma shook his head in denial.

"Isn't there a person who could smear poison on the edge of the teacup upright without attracting anyone's attention? Am I right? I never left the room at that time, and there was ample opportunity to smear the poison and clean it up. The poison container...Ms. Kosaka Shuri!" Touma coldly pointed to the woman in a sick suit.

"But according to what you said, isn't she just fighting for her life? Because since the beginning of the tea party, she has been drinking tea with her own cup!" Bafang said in surprise.

"Did you forget it so soon? The place where the poison is applied is the edge of the cup that the mouth touches only when the left hand holds the cup. On the other hand, as long as you keep holding the cup with your right hand to drink tea, it will definitely not There is a risk of poisoning!" Dongma said decisively.

"So when was the poison taken?" Ono asked immediately.

"I think she was ready to take it with her before she was admitted to the hospital. Then when the victim came to visit her, she smeared her teacup hill with poison, and then took the container to some place outside and threw it away. , Am I right?" Dongma said with a smile.

Hearing that, Shuli was just silent, even though her pale face was constantly shed sweat, making her look like she had confessed.

"But you have to be clear. At the time, Shuli drank blue butterfly bean tea, while Lingnai drank red roselle. Even if a slice of lemon floats on it, it won’t make us mistake it so obvious. The color is different!" Beppu defended Shuri at this moment.

"On the surface, it seems that this is true, but in fact, that slice of lemon is the key to this whole murder trick." Dongma said coldly...vW=Bu

"What's going on?" Kogoro asked suspiciously.=

"It's a very simple technique..." Dongma signaled Qiangtian to prepare for the experiment he had ordered earlier.

"First of all, this hot water is naturally the hot water in the pantry of the hospital, and this bag of tea is naturally Ms. Shuli's butterfly bean tea, of course, we also prepared the same lemon..." Dongma slowly explained.

"It's just ordinary things, is there anything special?" Kogoro asked suspiciously.

"Well, I'll just watch it..." Dongma said lightly, and Qiangtian made herbal tea and put the lemon in it.

It was at this time that amazing changes began!

"Everyone can notice that when the lemon is put into the butterfly bean herbal tea, the originally blue tea slowly turns red!" Dong Ma motioned everyone to pay attention to the changes in the tea.

"This is really amazing, Dongma, it's almost like a science experiment!" Xiao Lan exclaimed.

"In fact, the chemical principle here is also very simple. The tea itself and the acid in the lemon have a chemical reaction, and then it will slowly change color. Other teas will actually have the same changes..." Dongma said with a smile .

"Ah! It's violet tea! If you add lemon, it will turn from blue to pink!" Xiao Lan seemed to think of something.

"So by the same reason, since acid can turn tea from blue to red, adding alkalis that can neutralize the acid can make the tea turn blue." Dongma motioned to Gunda to continue. Take out the baking soda used in the tea cup.

The scientific name of the baking soda just mentioned is sodium bicarbonate, which is a kind of alkali.

"In simple terms, her modus operandi was to bring the poison to the hospital first, and then apply the poison to the right outside of her teacup when the victim came to visit the disease, and then use the excuse of'tea party everyone might as well taste several kinds of tea'. And Ms. Lingnai unsurprisingly chose Roselle which is close to red and purple."

"Then you take the opportunity to make tea, then replace the Roselle flower with butterfly beans like your own, and add a slice of lemon to it, so that the tea after brewing looks like a real Roselle flower. "

"As for when to change the teabags, I think it was when Ms. Reina was holding her mobile phone and looking at photos with Ms. Happo and Ms. Beppu. Because they were directly opposite, I put my own tea First put a slice of lemon to turn red, then push Lingnai's teacup forward, and then take Lingnai's teacup as if picking up his own teacup, then add baking soda to the teacup that I took, and then use the same method. , Push the teacup to Lingnai's left hand, so that when Lingnai subconsciously picks up the teacup and drinks tea, 1.0 will immediately poison her and die." Dongma said in a summary.

"As for the evidence, because of this modus operandi, the last thing must be removed, and that is the lipstick mark on Ms. Linnai's original cup. After all, the lipstick on the tea cup of Ms. Shuri, who is a hospitalized patient, would be suspicious. But the lipstick itself is not easy to wipe off, so in the entire process of handling the case when you have no chance to go to the bathroom, you must still keep the lipstick on your hand, as long as you verify whether the ingredients are consistent, it can become evidence." Dong Ma said with a sneer.

In the end, Shuli also revealed the motive for the murder. To put it simply, Lingnai deliberately asked her son who had a good cold to go to Shuli's home for review, and then let Shuli's son catch a cold and did not take the exam.

Chapter 1758 Kamijou Dongma Aquarium Incident (1) Second more

After the tea party homicide at the Santa Juliana General Hospital, Dongma and others went back to a peaceful day.

It was another calm weekend. Dongma and Xiaolan, together with a group of little ghosts who were also doing nothing, came to the Mihua Aquarium to visit and play together.

"Dolphins are so cute!" Ito Hui said loudly immediately after watching the dolphin show.

"Yeah, yeah, I jumped so high!" Mikami said with a smile.

"Speaking of which, where did the doctor park the car? Why hasn't it come back yet?" Step Mei asked suspiciously.

Because it is different from Xiaoai, Ito Hui and others, the trio of death came here with the Doctor’s Beetle.

"It should be in the fried noodle burger..." Dongma said lightly.

"Fried noodle burgers? Is there a burger with fried noodles in between?" Zhong Beifeng asked innocently.
