However, after investigating the tenants living in this household, the suspicion of all the tenants was ruled out.

There are no external murder suspects. That is the case of Lili's death. There is a bottleneck period.

Huang Dou even wondered for a while that this Tu Hua had lied in the middle. Because he himself said that he was not at home on the day Lili died, but why was it so coincidental that when Lili died, Tu Hua did not return all night? This can't help but make Huang Dou guess, is it Tu Hua who lied in the middle? Or, after he was with Lili, because the two of them had a conflict, Tu Hua lost control of his emotions for a while and killed Lili by mistake?

This is not impossible, but in the face of Huang Dou's inquiry, Tu Hua shouted that he was wronged.

"Comrade policeman, my relationship with Lili has always been very good! You may not believe it, but since Lili had my child, I have spoiled Lili in the palm of my hand! Faced with Huang Dou's questioning, Tu Hua shouted that he was wronged.

"Since you have such a good relationship with Lili, I can investigate. Lili is now more than seven months pregnant, and the two of you have not yet gone through the marriage procedures, what is the reason? ? Xiaowen directly said the doubts that he wanted as a woman.

Hearing Xiaowen ask, Tu Hua hurriedly replied with a sad face: "It's not what you think, at the beginning, maybe because the relationship between the two of us developed too quickly, Lili didn't dare to tell her mother, but later, Lili's belly got bigger, and the parents of our two families also sat together, specifically for the two of us, and agreed that when the child in Lili's belly was born, we would make up the banquet and tie the marriage."

As for why, until now, the two of us have not obtained a license, or reissued a wedding photo. The reason is also because Lili said that now she thinks her belly is too big and she doesn't look good in a wedding dress, and she wants to wait for the child to be born before taking a good set. Speaking of the agreement between the two people, Tu Hua said that he looked sad.

And Tu Hua also said that the reason why Tu Hua left Lili alone at home that day and went out alone was because Lili was about to take a pregnancy test, and she had to quickly find a way to find some money and take Lili to the hospital. So I went to a friend's house. And the record also shows that Tu Hua sent a red envelope to Lili's mobile phone halfway and asked her if she had eaten. But Lili never returned.

At that time, Tu Hua didn't care, thinking that Lili was asleep. So the sloppy Tu Hua is just one day.

So now, Tu Hua also expressed deep regret and self-blame for Lili's death.

But it was too late, and two lives fell like this.

"It's all my fault! If I hadn't been greedy for games, if I had come home earlier, this wouldn't have happened!! Tu Hua's self-blame was beyond words. It's hard to outline, and it's even harder to predict.

Now after an investigation of Tu Hua, the most likely suspect has been ruled out in this way. Tu Hua does have evidence that Lili died at the time of her death and was not at the scene.

Now that most of the external reasons have been ruled out, now we can only rely on Lili, and it can be said that she is a physical evidence for investigation.

Soon, the autopsy report of forensic doctor Yang Yang also provided a turning point for the whole case.

"The medical report of the deceased showed something abnormal! Body fluids contain methamphetamine! Forensic doctor Yang Yang, as he spoke, handed the physical examination report to Liu Ser.

"Methamphetamine, what is it?" When Huang Dou heard this, he couldn't help but look at the physical examination report in Liu Ser's hand curiously.

Hearing that Huang Dou didn't understand, Xiaowen on the side hurriedly explained to Huang Dou: "Brother Yimao, this methamphetamine is the main ingredient contained in methamphetamine!" ”

"Meth ???" When Huang Dou heard this, he couldn't help frowning: "You mean to say that this Lili has a history of drug abuse before her death?" ”

With this astonishing discovery, Huang Dou hurriedly called Tu Hua, Lili's boyfriend who had been ruled out of suspicion, back to re-investigate.

"Yes! Lili and I are both addicted to drugs! Tu Hua didn't lie this time, and admitted it directly.

"And that's not all! I also found out that you have a history of drug trafficking! Huang Dou looked at the young man who looked sunny and generous with a serious face.

Finding that Huang Dou had already understood all his situation clearly, Tu Hua couldn't help but lower his head: "Yes!" When I really don't have any money, I will help bring a little bit of drugs when I and Lili are short of money, but I'm just a messenger, and I haven't touched that thing! Tu Hua hurriedly explained, because he himself knew how much of a crime it was to reverse drugs.

Hearing Tu Hua's words, and in view of the actual investigation, it was indeed found that Tu Hua was right, although Lili and Tu Hua usually take drugs, but the amount of drugs consumed by the two of them is not large.

And the forensic doctor Yang Yang continued to perform the autopsy report on the deceased and found that the deceased did not die of methamphetamine overdose. Rather, he died of another chemical – carbon monoxide!!

Woman: "Carbon monoxide? What is this?? ”

Man: "As a female corpse that traveled through ancient times, you may not really understand what carbon monoxide is!" ”

Female: "Ancient female corpse?? What did you say??!?! ”

Man: "What, I said it wrong, it's the soul of an ancient beauty!" Beautiful Soul!! ”

Woman: "That's pretty much it!!" Hurry up and get down to business!! What exactly is carbon monoxide!? I'm in a hurry! ”

Man: "You know how you cook now?" The main ingredient in it is carbon monoxide! ”

Woman: "Gas is carbon monoxide?" Isn't that thing combustible? ”

Man: "Smart, not only can it be burned, but this carbon monoxide is also a highly toxic substance, and after the human body inhales, it will die of gas poisoning!" ”

Woman: "So serious? Isn't that the same as the legendary gas bomb!! ”

Man: "Uh... It can also be said that in home life, carbon monoxide poisoning incidents generally occur because of the gas in the kitchen! ”

Woman: "There is such a terrible thing! It's better to be careful in the future! Thanks to the dog's leg can't cook, like him, if he really uses gas to cook, I doubt that one day, we will die here! ”

Man: "Haha... You're right! ”

Woman: "I'm still alert!!" ”。

"So, Lili was hit with carbon monoxide, so she died?" After such a circle, from the beginning that he thought Lili was murdered, to the later found out this result, Xiaowen was also surprised.

"Alas! It's all because of the water heater that Lili used to take a bath in the rental room, this water heater burns natural gas, because Tu Hua didn't connect it to the outside interface, so there was no carbon monoxide discharge, after Lili took a bath, the window in the room was not opened, and a closed environment was formed indoors, which eventually led to this situation! Huang Dou said with a sigh.
