Criminal Investigation: Forbidden Rose

According to the report of the forensic team, the cause of death of the three deceased was the same: indeed, they were all carbon monoxide poisoning.

The internal organs and tissues of the deceased were all cherry red, and the ratio of carboxyhemoglobin in the heart blood of the three all exceeded 50%, and there were no other lethal poisons.Among them, the contents of the stomach of the deceased corresponded to the barbecue residue on the dining table, and part of the digested matter had been transferred to the duodenum. That is to say, the deceased did not die on the spot, but fell into a coma first, and the digestive tract still had certain activities.

However, secobarbital residues were detected in the bodies of all three of them, and they were not fatal, but enough to let them sleep for several hours.After comparing the food sources on the dining table, the forensic team found that the secobarbital came from peanut milk after meals.

Based on the above findings, Yu Min reconstructed the events of that night for everyone: a family of three chatted while drinking peanut milk after eating barbecue.The secobarbital took effect very quickly, and it took about 10 minutes to take effect, so the three of them fell into a coma very quickly.Subsequently, the bamboo charcoal continued to burn in a space with insufficient oxygen, and the carbon monoxide content continued to increase. After being in a coma for about three hours, the three died completely around midnight.

So, the question now becomes - who put the scobarbital in the peanut milk?

The peanut milk in Xu’s refrigerator is a “1L” family sharing package, but only the fingerprints of Yuan Yongfang and Xu Heguang were found on the bottle cap and body.The police also found a supermarket bag in the trunk of Xu Heguang's car, with a small ticket in it, showing that Xu Heguang bought the peanut milk on the way back to his parents' house, and also bought the beer and dipping sauce that night.

As for the source of the hypnotics, it has not yet been ascertained.The old man of the Xu family is just a medicine jar. He has to take 23 different medicines every day, many of which are calming and sleeping medicines, but Xu Jianguo doesn't take them.The three deceased, Xu Huayu, Ji Tong, and even Zhao Chunhua—anyone who may be related to the case could not find the prescription records of secobarbital.

Seeing this clue go to a dead end again, Xia Yi scratched his head irritably: "The hypnotic drug found in the body can rule out accidents, but it is impossible to commit suicide with the whole family, right?"

"Suicide doesn't make sense at all." Jiang Mo tapped the table with his index finger, "None of the three members of the Xu family has a history of depression. Xu Huahao's business is booming, and Xu Heguang is about to get married and start a family. It's a happy event. How could he bring his family to die?" ?”

But at the scene, there was no conclusive evidence that the fourth person was present.

In Xu Heguang's car, only the biological information of Xu Huahao, Xu Huayu, Ji Tong and his assistants were found.Among them, Xu Huahao died, and the other three had clear alibi.Only the fingerprints of Yuan Yongfang and Zhao Chunhua were found on the kitchen door, window, and range hood.These two women are usually in charge of the kitchen, so they can't explain anything.

So ruled out, the police can only suspect Zhao Chunhua.However, the Xu family paid Zhao Chunhua much more than ordinary families. Not only did they have weekends off, but they also included board and lodging on weekdays. Many nurses wanted to work in such a family even if they were overwhelmed.If Zhao Chunhua killed this family, it would be tantamount to ruining his job.Not only could the police not find a motive for the killing, but they also could not prove that she was at Xu's house on Saturday night.

In fact, so far, they haven't even been able to definitively prove that it wasn't a suicide.

……

Furun Group is a well-known local enterprise, and this incident directly alarmed the Municipal Bureau.Before the case was solved, it was exposed on the Internet by unscrupulous media, and the pressure of public opinion on all sides was great.The above directly issued a death order-48 hours-the nature of this case must be given an explanation.

If it doesn't work, the city bureau will take over directly, and the branch office will be in trouble.

But now, there are only twelve hours left before the deadline.

The hour hand crossed 12 o'clock again, and entered a new day.In the conference room of the Criminal Investigation Detachment, each group had finished their reports, documents and photos were spread out on the table, and the air pressure was frighteningly low.Most of the police officers involved in this case hadn't closed their eyes since the incident happened the day before yesterday. Each team was busy taking samples, analyzing, questioning, and investigating... At this moment, each of them had red eyes, black and blue eyes, and stubble on their chins.

When people think about the same problem over and over again, especially in the case of extreme lack of sleep, people are more prone to hallucinations.In a daze, Xia Yi seemed to see the old man Xu who couldn't speak or stand up from the wheelchair, a strange smile appeared on the corner of his mouth, his mouth was drooling wildly, his eyes rolled around, and he walked slowly towards The kitchen is grilling...

Thinking of this, Xia Yi frantically shook his head.

At this moment, Xia Yi's cell phone rang, and it was the security guard on duty, saying that the takeaway snack you ordered has arrived, come down and get it.

Xia Yi was baffled, and just about to say "I didn't order it", she glanced over the window and was stunned when she saw the tall and thin figure outside the security gate downstairs.

Five minutes later, Shao Lin walked in with twenty cups of milk tea and coffee, and three buckets of spicy fried chicken.

The lifeless meeting room was revived in an instant.

Shao Lin is very thoughtful. Drinks range from sugar-free iced oolong to Internet celebrity milk tea to hot drinks. Everyone can find their own share.

Many of the people here are not familiar with Shao Lin. While wanting to eat and drink, they are embarrassed and polite: "This, this is too expensive..."

"No fee." Shao Lin smiled slightly, "Officer Xia asked for it, and I just helped get a takeaway."

Yan Jingjing flew over and snatched Zhizhi Berry away: "Team leader! I love you to death!!!"

Xia was given a favor for nothing by pressing his head, with a row of question marks above his head.He opened his mouth, and a naive "It's not me, I don't know anything, you're just talking nonsense" came to his lips, but Shao Lin stepped on his big toe with a smile, and instantly changed his words: "No————You're being polite! !!"

Jiang Mo glanced at the cup of hot drink brown sugar and milk in surprise, and his eyes flicked past Xia Yi.The deputy detachment leader smiled knowingly and didn't expose it.

Everyone took food and drink, and the originally tense atmosphere relaxed a lot, so they took a break and chatted with each other.

Holding a cup of clear coffee, Shao Lin walked towards the forensic team: "Director Yu."

When they were at the scene before, the two met face to face.It's just that the forensic team was too busy at that time to speak.

Shao Lin raised the corner of his mouth and reached out his hand: "I'm Shao Lin. Last time, Director Yu got up to work overtime for me in the middle of the night, and I never had time to thank him in person." As he spoke, he glanced at Xia Yi with a smile: "Otherwise, they They refused to let me go home and sleep."

"Where is it? This is my job." Yu Min still had no expression on her face, but she shook hands firmly. Mistakes, interns lack of experience."

Shao Lin stopped being polite, and his eyes fell on the folder opened in front of Yu Min: "Director Yu is very interested in trace inspection?"

"It is said that the job of a forensic doctor is to talk to corpses..." Yu Min took a sip of iced tea and said in a low voice, "But sometimes corpses refuse to speak, and the answer is hidden in the environment."

In front of Yu Min was a paper published in "Criminal Investigation Technology".Because indoor barbecue carbon monoxide poisoning cases are common, many "murders" will also be packaged as barbecue suffocation.So, the team for this paper tried burning lots of bamboo charcoal in rooms of different sizes.Finally, a model with bamboo charcoal quality and burning time as independent variables and carbon monoxide concentration as dependent variable was concluded.

In fact, in criminal investigation, many experiences are summarized through this simulation method, such as the analysis of fire traces, the prediction of the time of death through the temperature of the corpse and the ambient temperature, and so on.

Shao Lin was silent for a moment, and seemingly unintentionally started another topic: "Zhao Chunhua said that Xu Huahao used electric ovens for barbecue at home before. I have always wondered why it was replaced with charcoal this time? I don't eat much. Barbecue, but I searched the Internet, and many people said that charcoal grilling is better than electric grilling, I don’t understand why.”

Yu Min shook her head: "I don't eat much barbecue either. It's not healthy."

Shao Lin smiled and tapped the paper on carbon monoxide with the tip of a pen: "Then you want to know why charcoal grilling is better than electric grilling?"

Only then did Yu Min realize that Shao Lin was seriously discussing with himself which roasting method is more delicious!

"You mean—" Yu Min seemed to think of something suddenly, and the eyes behind the rose gold frame lit up instantly.He stood up with a groan, with a rare look of excitement on his face: "I understand, I understand! Thank you, Teacher Shao!"

Yu Min didn't even have time to tidy up her folders, picked up the car keys, and greeted her students: "Hurry up, go back to the Fajian Center, let's do an experiment!"

"What, what? What experiment?" Xia Yi was startled by Yu Min's fight. He glanced at Yu Da's forensic doctor and then at Shao Lin, his eyes were confused, "What are you two doing here? Are you still discussing who is better at charcoal grilling and electric grilling? I also think charcoal grilling is delicious!"

Shao Lin looked at the back of Yu Min leaving in a hurry, smiled lightly and shook his head: "Director Yu is a smart man."

Xia Yi blinked, and his eyes suddenly became suspicious: "...Are you implying that I am stupid?"

Shao Lin was very innocent: "I didn't."

"Then what experiment is he going to do?"

"I'll tell you when the results come out."

Xia Yi gritted her teeth: "You think I'm stupid!"

As he said that, he grabbed Shao Lin's wrist, dragged him to the corridor outside by force, and said in a low voice: "Also, why do you say that I invited you? How much is it, I will transfer it to you. "

Shao Lin lowered his eyes slightly: "No need, I don't have much money."

He thought about it, and decided to explain patiently: "I'm not a member of the bureau. It's not appropriate for you to let me participate in such an important case. Who knows which colleague will see it in his eyes and keep it in his heart." ? If I invite everyone to drink milk tea, the meaning of flattery is too obvious, but if you invite everyone to drink, it is called Midnight Compassionate to colleagues. Do you understand?"

There are so many twists and turns in Xia Yi's stubborn mind.Although he said "oh", his eyes were confused, probably because he had been working on the case for too long, and now he was even more stupid.

Shao Lin: "..." Forget it.

"Strange," Xia Yi began to mutter again, "You know that girl Yan Jingjing likes Zhi Zhi Berry Berry, but why did you order a cup of brown sugar milk for Jiang Fu? You can drink it if she wants to drink it." Know?"

Shao Linxin said that the first time he saw Jiang Mo, there was a transparent water bottle on the other's desk, but in the past few days, she had replaced it with an insulated water bottle, so it was obviously her menstrual period.Buying all iced drinks is not friendly to girls.But there is really no need to repeat this mental journey with Xia Yi again, Shao Lin is helpless: "Officer Xia, you can't take a closer look at life!"

Xia Yi felt wronged: "I observed it!"

Shao Lin sneered: "You observe. What did you observe?"

"After my careful observation, I found that you are smarter than the average person."

Shao Lin: "..." There is no way to talk today.

He turned to leave.

Xia Yi shouted: "Hey! You, you came here in the middle of the night, aren't you going to sleep?"

Shao Lin was very angry: "Can't sleep!"

Xia Yi rubbed her red eyes, and yawned: "If you can't sleep, let me help you sleep. My whole mind is confused, let me go to the workstation and squint for a while."

Shao Lin returned to the conference room and reviewed what they discussed earlier by himself. After reading the materials, it was already four o'clock in the morning.As soon as he went out, he saw the criminal investigation office lying on his back, and Xia Yi changed from a husky to an Alaskan pig.

Shao Lin's eyes traced his facial features carefully, and an inexplicable tenderness filled his heart, and he seemed to feel better.After all, it is more lively than home.He didn't want to lie alone on the bed, staring at the sky getting brighter.

……

Just when the sky was turning pale, Xia Yi woke up suddenly with a ringing phone from the sub-bureau.

Exciting good news came from the Fajian Center——Yu Min finally found the ironclad evidence that there was a fourth person at the scene!
