Finally, it was deduced that there was something wrong with the food.

There is a cafeteria in the university, and dinner is served from the cafeteria. I watch the food being prepared and take it to me, so there is no problem.

At 11:30 in the middle of the night, takeaway coffee was delivered. Night shift workers usually order coffee, so when they received the coffee, neither the two people at the door nor the security guard had any suspicion. Plus, it was already midnight, so people's vigilance would be a little lax. Brown

The doctor also had a glass. After Forbol knocked on the door, Dr. Brown opened the door and took it, thanking him.

This is the only thing that comes in from the outside!

But the question also arises. If the coffee was poisoned, why did the two agents and a security guard just fall asleep, but Dr. Brown died?

And at about one o'clock, the three of them woke up and drank the unfinished coffee. Why didn't they fall asleep again?

Through the analysis of the coffee cup and plastic recovered from the trash can, the murderer smeared poison on the outside of the coffee cup.

What the security guard and the two agents got was supposed to be for sleeping, but the poison was spread through smell. After the three fell asleep, the poison outside the cup dissipated and evaporated over time, so when they woke up,

The sleep gas emitted outside the cup is no longer enough to make them fall asleep again.

The only thing that can cause death is Dr. Brown's cup, but how can the murderer be sure that Dr. Brown must have taken this cup?

The reason is that Dr. Brown has always drank decaffeinated coffee, and this is the store he always likes to order.

Dr. Brown was staying up late doing research for the bureau. He thought it was the coffee the bureau ordered for him, so he accepted it without any doubt. When he took it in, opened the plastic bag and took out the coffee. Regardless of whether he drank it or not, the coffee

The smell on the cup wafted along with the fragrant coffee aroma and penetrated into his nostrils.

"Idiot, idiot!" Tou was furious in the office. He rarely got so angry: "I've said it before, be vigilant, be vigilant, and something will happen if you take over! I don't know what happened to these two guys.

Recruited!"

Xining and Karak, who had returned to the bureau and were sitting across from each other, really didn't know what to say.

"Bang~" He hit his fist on the desk, and his nostrils swelled with anger: "Check, find this guy out!"

Find out? Hehe, it's easier said than done. The method of committing the crime is so wonderful. If this guy writes a book, the plot may be more exciting than Mrs. Rossi's.

If he hadn't known about it in advance, Dr. Brown would definitely have committed suicide.

After coming out of the head office, the two of them went to the laboratory.

"Carol, what do you think?" Karak felt very heavy.

How do you see it? How do you know how to see it? You think you are Yuan Fang. Even if Di Renjie comes, he may not be able to understand the poison formula.

Dr. Brown's body had been stripped of all clothing and placed on a metal dissecting table. The body was covered with a white cloth, covering most of the torso, including important parts, and his skin at this time was even paler than the cloth.

Nathan from the laboratory department was actually drinking a cup of coffee next to him, along with potato chips.

"How's it going?" Karak glanced at the wrist with the blood vessels cut open. At this time, the wound had been wiped with an alcohol cotton ball, and the scratches next to it became clearer.

Nathan turned around, and the office chair under his plump buttocks turned half a circle, aiming at the medical viewing light box on the wall. X-rays were sandwiched on the light box, showing bones, internal organs, brain, etc.

Nathan couldn't help but marvel again: "It's a spray. Sprinkle it evenly on the cup. It's almost consumed. If it's later, there won't even be any dregs left. It's higher quality than the powder used for you."

Karak deliberately pretended to be a little annoyed and said with humor: "I also got a doctorate."

"Maybe he was more careful." Xining said casually. What he urgently needed to know now was who this guy was and his motive for committing the crime.

Nathan stood up, put down the coffee cup, put on a pair of medical plastic gloves, walked to the corpse, and carefully lifted the corpse's cut wrist. Because the corpse had almost no blood, it would not be as hard as other corpses, but still remained soft.

Degree: "Before he died, he scratched it hard with his left hand. There were scraps of skin and flesh deep between the nails of his left hand. It must have been hallucinogenic."

Even though it had been washed away by water for more than seven hours, it was still there in the nail cracks, which proved that it was scratched with sufficient strength at that time.

Xining thought for a while and asked: "Will the hallucinations seen before death be targeted?"

"Well~" Nathan straightened up and scratched the back of his head with his other ungloved hand: "Probably not. Just like eating poisonous mushrooms by mistake, you will see different things. But some are still the same.

Although the deepest fears in human beings are different, they are mostly similar."

"Like?" Karak asked.

"For example, the abyss, the universe, huge objects. There are also loneliness, darkness, flames and magma. Beasts, poisonous snakes, spiders, poisonous insects..." Nathan glanced at the wound: "This is most likely because he mistakenly thought there was something terrible on his wrist.

, or the hand turned into something like that, so I took the knife to 'kill' the thing. Just a random thought, for reference only."

It's quite rigorous, but judging from the monitoring and results, the possibility is still very high.

A layer of callus on the middle finger of his left hand proves that Dr. Brown is left-handed and writes with his left hand. Therefore, all his self-harm behaviors occur subconsciously and are not specific.

Looking at Dr. Brown lying on the dissecting table, his upright face was as calm as if he was sleeping. He looked pretty good, and there should be a lot of crushes in the university. Humans with such high IQs should breed two more.

Descendants. According to the information, there has been a family, but most women in this country do not have a lofty spirit of dedication, so they are divorced and have no children yet. They are in their early forties, when they are young and mature with experience.

The best age for scientific research has been interrupted.

He let out a long sigh, which was a pity.

Mo Ming: "Haha."

Haha, even if the tiny humans are ants in the eyes of the Lord God, it doesn’t stop me from paying more attention to the beautiful and smart ants. When encountering a beautiful and special creature, the normal reaction should not be to want the other person to have more babies.

How many monkeys?

At this time, the intern came and found the person who delivered the coffee. Xining and Karak rushed over.

The store itself is also a 24-hour convenience store, so it is open so late.

The shop owner recalled that these cups of coffee were reserved over the phone. He took the order, and after finishing it, because there was no one else in the shop, he delivered it in person. The university is not far from his shop, and there are only about 600 meters between the two doors.

Meters away, students doing scientific research or studying for exams in the evening often order coffee and snacks.

This city is not safe at night. Even on such a short road, he carries a gun with a license.

When he was approaching the entrance of the university, a man was already waiting there. After checking the information and everything matched, he gave the coffee to him and got the money.

Because it only happened last night, I remember it very clearly. The boss said with certainty: "Five dollars for a cup, four cups of coffee for twenty dollars. He gave a total of twenty-five dollars, one piece of twenty, and one piece of five dollars is considered a tip."
