If it was Shi Wenfeng who took the initiative to contact the murderer, forget it.

If it is the second possibility, under the premise that Lin Chengzhao has denied that he did it, who else in this world will know about the existence of that tunnel?

Could it be that Shi Wenfeng really said it to the murderer?

Everyone couldn't help frowning, only to feel that this case seemed to have become complicated all of a sudden.

Xu Jing glanced at them, then withdrew his gaze, continued to check the corpses of his subordinates, and said, "The deceased's lips and nails are cyanosis, the conjunctiva of the eye is bleeding, and the tongue has signs of bite bleeding......"

Xu Jing said, her mind running rapidly.

These conditions appear to be consistent with the characteristics of death by asphyxiation.

After a pause, she reached out two fingers and dug into the deceased's mouth, and when she took them out again, her gloves were stained with some mud and sand.

Seeing this, Yao Shaoyin immediately said: "In this way, the deceased did drown. The presence of mud and dirt on the nose and mouth, dark spots on the eyes, and cyanosis of the lips and nails are all consistent with death from drowning. ”

Although Yao Shaoyin is not a professional, he has investigated the case for so many years, and he knows some post-mortem knowledge.

Xu Jing shook her head and said, "Not necessarily, the deceased who died of drowning usually has mushroom-like foam on the mouth and nose, but there is no one on Shi Wenfeng's corpse." ”

She moved her hand to the deceased's chest and abdomen and pressed hard, turning the body again, but still no mushroom foam was seen.

When the cold water weak fluid stimulates the human tracheal mucosa, the human mucosa will subconsciously secrete a large amount of mucus, which will be stirred with the weak fluid and air together to form a large number of fine and uniform white foam, which is the mushroom-like foam.

If a person is thrown into the water and drowned while he is alive, he will definitely produce such a mushroom-like foam, so whether there is a mushroom-like foam is an important basis for judging whether a person was drowned before death.

And on Shi Wenfeng's corpse in front of him, there was no such bubble.

After listening to Xu Jing's description of the mushroom-like foam, Yao Shaoyin immediately recalled the drowning cases he had handled before, and frowned slightly: "Indeed, most of the people who die from drowning will have such white foam on their noses, this Shi Wenfeng didn't, could it be that he didn't drown?" ”

"I don't think so, although sediment was found in his mouth, it is normal for a person to enter the water after death, and under the impetus of the current, there is sediment in the mouth of the deceased."

To really determine whether it was drowned before death, an autopsy is required to see if there is weak fluid in the stomach and duodenum of the deceased.

Xu Jing continued: "What's more, Shi Wenfeng's nails are very clean, and when ordinary people drown, they will subconsciously struggle to catch something, and their nails are usually full of mud and sand.

Although Shi Wenfeng's body looked like a drowning, the characteristics of cyanosis of the lips and nails, black spots on the eyes, and a bite on the tongue were not unique to the drowning person. ”

Yao Shaoyin was slightly stunned, and subconsciously asked, "What else could be the situation?" ”

Xu Jing raised her eyes and glanced at him, and said lightly: "Poisoning." ”

Everyone was slightly stunned.

Xu Jing was a little distressed, if she could conduct an autopsy on Shi Wenfeng, she would be able to make a more accurate judgment, but she had never used this method to perform an autopsy in front of Yao Shaoyin and them, they might not be able to accept it, at the beginning in Anping County, it was also because Xiao Yi forcibly opened the way for her in front that the people of the county government of Anping County could accept her means of autopsy so quickly.

The most important thing is that Shi Wenfeng is not a nameless corpse, and if she wants to dissect him, she must obtain the consent of his family.

These two things cannot be solved in a short period of time, Xu Jing can only sigh secretly, and silently recite in her heart that the autopsy is still a long way to go in Da Chu, and carefully looked at Shi Wenfeng's corpse again, and finally, she broke his mouth again, leaned down to take a closer look, but was suddenly stunned.

Shi Wenfeng's mouth actually had a faint taste of wine!

Because the smell of wine was almost volatilized, when Xu Jing checked his mouth for the first time, she didn't get so close as this time, so she didn't notice this.

After she said this, Yao Shaoyin said with a deep face: "The smell of wine? Shi Wenfeng drank before he died, who did he drink with? ”

This answer is about to come out, how can he, a person who has just done something wrong, have the leisure to find a friend to drink, only possible to drink with the murderer.

If he really died of poisoning, the murderer probably put the poison in the wine!

A servant couldn't help but say: "In this way, the relationship between Shi Wenfeng and the murderer is very good, if the murderer is really the one who bought Shi Wenfeng to poison, I thought that Shi Wenfeng was very wary of him." ”

That's right, if it's just a simple relationship between buying and being bought, Shi Wenfeng's attitude towards that person should be more vigilant and jealous, how could he drink with him with such interest, and obviously drank a lot, otherwise he wouldn't have had a faint taste of wine in his mouth after he died for so long.

This can only show that Shi Wenfeng and him are likely to have known each other for a long time, and even be very familiar with each other!

Even if the murderer is not the one who bought him, he must be his acquaintance!

Xu Jing lowered her eyes and pondered for a moment, stood up and took off her gloves, and said, "I want to go back to the mansion and ask Lin Chengzhao about something." ”

When Lin Chengzhao was escorted to Xu Jing again, he already had a depressed expression of resignation, Xu Jing sat on the chair, glanced at him with his eyelids, and said, "Lin Chengzhao, the person who instructed Shi Wenfeng to poison the medicinal soup in our Xinglin Hall is really not you?" ”

Lin Chengzhao's body stiffened slightly, and he suddenly raised his head and his eyes were red, and said, "I said, no!" Am I going to lie to you now?! Xu Jing, do you have to let me go to hell and feel bad?! ”

Xu Jing looked at him carefully for a moment, and said, "I don't think it's you, either, but judging from what we have found so far, it is very likely that the murderer knows the tunnel in Shi Wenfeng's courtyard, and the person who knows the existence of that tunnel, who else besides you?" ”

Just now, she asked Yao Shaoyin to check the landlord of the courtyard, but found that it was just a fake landlord, who was entrusted by the Lin family to take the name of the landlord and make a trick, and he didn't know what the existence of the authentic was.

That is to say, that courtyard is actually the Lin family, and the only people who know the existence of that authentic should be the Lin family.

Lin Chengzhao was slightly stunned, his brows quickly twisted, and he shook his head lightly and muttered: "Impossible, the only people who know the existence of that authentic existence are me, my two sisters-in-law, and ...... and a few stewards of Guangming Hall who have been with me all the year round, but how could they hide from me and let Shi Wenfeng poison your medicinal soup! Why are they doing this?! ”

Xu Jing also felt a little weird.

No matter what case is investigated, the motive of the murderer is very important, and many old criminal police officers even have an unwritten trick to solve the case - to see who is most beneficial to a case, whose motive is the greatest.

It can be said that 90 percent of the murderers have a certain purpose in committing their crimes.

However, this case is very strange, the person with the most motive for committing the crime was the first to be ruled out, and now the people who may be suspected of committing the crime do not see what motive they have for doing it.
