Detective from The Future

"Han Bin, you can say a few words."

Han Bin glanced at his notebook, "The incident was at the Jiujiang Barbecue Restaurant in Wanda Shopping Mall. I was also eating in that restaurant and was one of the witnesses. However, I did not notice the deceased until the deceased’s girlfriend, Ma Xiaolin. Shouting, I ran over to check the situation.

The deceased took a lot of time from the poisoning to the death. It took only a few minutes. I called 120 and called the police. Everyone knew what happened after that.

There were a lot of people on the scene when the incident occurred, and relevant personnel have already made notes. The deceased and his girlfriend Ma Xiaolin entered the restaurant at 6:32 pm, became poisonous at 6:50, and died at 6:57. According to the confession of the deceased’s girlfriend and mother, the deceased’s body was always healthy and he did not suffer from any diseases. In addition, Ma Xiaolin, the deceased’s girlfriend, ate with the deceased. Except for a bottle of beer, the two had exactly the same diet, but Ma Xiaolin showed no signs of poisoning.

The above is the general situation of the drug case. "

Ding Xifeng said, "Who else wants to add?"

No one answered.

Ding Xifeng continued, "Lao Ma, what have you discovered in the technical department?"

Ma Xiwen said, “After bringing back the ingredients and exhibits sealed in the restaurant, we conducted a large number of tests, but we did not find deadly toxins.”

Han Bin said, "There is no beer either."

"No."

Wang Xiao asked, "Have you checked all the ingredients on the deceased's table?"

"All were checked, and no harmful ingredients were found to be fatal."

Wang Xiao frowned, "That's weird, how did the victim get poisoned?"

Zhu Jiaxu said, "Is it possible that the deceased had a special disease instead of poisoning?"

Ding Xifeng looked at forensic doctor Li Can, "Forensic doctor Li, is this possible?"

Li Can organized a language, "According to the reaction of witnesses, the time from the appearance of the body to the death of the deceased was very short, plus some symptoms at the time of the deceased's death. Only a few diseases matched, but I checked the deceased's archives He did not have a similar case. At the same time, I did not find any related illnesses when extracting the corpse of the deceased. I can confirm that the deceased was indeed poisoned."

Han Bin went on to say, “After the deceased was poisoned, I hit 120. Although the victim was dead when 120 arrived, the doctor still checked the physical condition of the deceased. I asked the female doctor at the time and she estimated It takes no more than ten minutes for the deceased to go from poisoning to death.

However, the technical department did not find any deadly poisonous materials in the restaurant, which means that the deceased was probably not poisoned in the restaurant. Is it because the doctor made a mistake in judging the time of the onset of the poison? The poison is not that strong, then fast? "

Li Can said, "No, I agree with the doctor that the victim was indeed poisoned to death, and this toxin is very powerful and can cause death in a short time. From the point of view of the toxin, it should be sodium cyanide. If the drug is sufficient, it will indeed cause death in a short period of time.

I tested the sodium cyanide content in the deceased's body, which was extremely high enough to cause death in ten minutes, so I agree with the female doctor's point of view. "

Ding Xifeng said, "This doesn't make sense. If according to the conclusion of the forensic doctor, the deceased must be the poison taken in the restaurant, but the technical department checked the items in the restaurant, but no related toxins were found. Isn't it the conclusion of your two departments? Contradictory."

Li Can stood up, walked to the projector, and put a photo on it, "I found this item in the deceased’s stomach while uncovering the deceased’s stomach. I think it might be useful for the detection of the case. ."

A photo appeared on the projector. There was a glassware on the table. The glassware contained some unknown objects, which looked smaller than millet grains.

Wang Xiao said, "Forensic Li, what exactly is this, no one can see clearly at such a small size."

Li Can said, "The main ingredients of this item are gelatin and food coloring."

Zhu Jiaxu listened, feeling the same as if he didn't, "What the hell? What is it for?"

Ma Xiwen said, "Gelatin and food coloring are the main ingredients for making capsules."

"Capsule." Han Bin muttered and asked, "It's the skin of granular medicine."

Li Can said, "Some drugs can irritate the esophagus, so the drugs are made into granules and packed into capsules. The capsules are not easy to digest, which can play a protective role."

Han Bin reacted, "You mean the murderer probably put the poison in the capsule because the outer skin of the capsule is not easy to digest, which delays the onset of the poison."

Li Can said, "In theory, this is possible, but I don't know much about investigating the case, and you still need your own judgment."

Ding Xifeng said, "Yes, the clue provided by Li Can is very important. Assuming that the murderer used the capsule to delay the onset of the poison, then the actual time for the deceased to take the poison must be pushed forward. And it is speculated that if the poison is placed in the capsule, the poison How long can it be released?"

Li Can thought for a moment, "This situation is more complicated. It depends on the quality and thickness of the capsule, as well as the digestive function and physical condition of the deceased's stomach and intestines. It allows me to intuitively judge that the error will be greater."

"Then count the error in and give an approximate time."

"It's about one to five hours."

Han Bin said, "That is to say, the scene of the poisoning was not the Jiujiang restaurant, it was just the place where the poison was found. If you move forward according to the time of the poisoning, the time for taking the poison is roughly between 1.50 and 5.50. Let's not It is not clear where the deceased was during this time, nor is it clear who he has contacted."

Ding Xifeng said, "Then check, not only check the whereabouts of the deceased's poisoning time, but also check the deceased's surrounding relationships, to see who has conflicts and interests with him, and has enough motivation to poison him."

"Yes." Han Bin replied and continued, "In addition, why did the murderer use this method to kill? Can you infer some clues to the murderer from his method of killing?"

Zhu Jiaxu said, "Generally, this kind of killing method of poisoning is common to female murderers. Ma Xiaolin is precisely a female. Will she be the murderer?"

Ding Xifeng said, "I think the murderer's purpose for doing this is more like creating an alibi for himself. If it weren't for Li Can's carefulness and seriousness, we would not be able to guess that the poison was contained in a capsule, and it would definitely misjudge the time the deceased was poisoned. , If this judgment is wrong, it is impossible to catch the real murderer.

Assuming that Ma Xiaolin is the murderer, she finally created an alibi through the capsule, and why she had to eat with the deceased to increase her suspicion, wouldn't it be unnecessary? These two practices are completely contradictory. "
