Miss Yin is the victim of this case, and the filth spit out of her stomach makes the dog stunned, even if people scratch their heads and suspect the Yin family, they will not guess that it is the two little girls who are red, willow and green that she drugged and turned over.

"A victim who has died cannot be a criminal other than suicide", this is a deep-seated mindset, and in an obvious case of homicide, who would doubt the victim himself?

Even Qin Lin, who is experienced and thoughtful, has been misled for a long time, and he never thought of the possible surnames of Miss Yin's own drugged and fascinated the two girls, until Xu Xinyi mentioned whether one of the two little girls was drugged, Qin Lin suddenly thought:

Bonus and willow green can be suspected, why can't Miss Yin be suspected?

By reasoning from this, all difficulties will be solved in an instant, and all irrational phenomena will be explained logically!

The next animal experiment on the remaining tea in Miss Yin's teapot fully confirmed the above inference - if another criminal was drugged to stun Hua Hong, Liu Lu, and never let Miss Yin go, wouldn't it be more convenient to be stunned and robbed than to be violently kidnapped? At least there won't be any trouble shouting for help.

So there is only one conclusion: Miss Yin herself stunned the two maids, went out to meet the criminals, and was finally killed in the pool!

Qin Lin explained this analysis and discussions, and everyone was dumbfounded when they heard it, although the conclusion was incredible, but the reasoning was meticulous, and they had to believe it.

Whew~~ Wang Shizhen let out a sigh and sighed: "If it weren't for General Qin's guidance, I'm afraid this official would still be in a dream!" ”

If it is said that he asked his son Wang Shiqi to go to Yangzhou to report the news, he also considered Qin Lin and Zhang Zixuan to be friendly, and indirectly took advantage of Zhang Juzheng, the young master of Yuanfu, this time it is entirely because of Qin Lin's extraordinary ability, and he is optimistic that he will become a rising star in the Ming officialdom in the future.

Lu Yuanzhi, Bai Hao and everyone suddenly realized that in fact, if this case was that the two girls were stunned and Miss Yin disappeared, they would have suspected that it was a romantic lawsuit in which the lady of the boudoir stunned the girl and eloped with her lover; But Miss Yin died extremely miserably, with bruises all over her body, and her lower body was stuffed with jelly meat, drowning in the pond. This has absolutely nothing in common with ordinary elopement cases, and it seriously interferes with their train of thought, if it weren't for Qin Lin's point, they would have gone astray.

Xu Xinyi shook her head, immersed in sadness because of what happened to Miss Yin, and her voice was sighing: "This Miss Yin, she looks like she is gentle, I really didn't expect her to ...... Anyway, if you want to elope, it's a lawlessness like Miss Ben, so she can do it......"

Qin Lin said that he was very thirsty for a long time, and he asked the Yin family servant to bring a bowl of hot tea to drink, and when he heard this, he immediately poofed and squirted the tea out of the distance.

Xu Xinyi accidentally slipped out the emotion in her heart, she stuck out her tongue mischievously, glanced at Qin Lin quietly, and grinned sideways.

"I didn't hear it, we didn't hear anything," Lu Fatzi blocked his ears with his fingers, and he was serious like never before.

"Ahem", Wang Shizhen pretended not to know, turned around and asked Bai Hao: "So, Miss Yin originally eloped with someone, but she was killed by someone who was unladylike?" ”

What Shangguan said was not very good, and it was difficult for his subordinates to point it out, so Bai Hao had to pretend to groan and not answer for the time being.

Qin Lin shook his hand and said with a smile: "What Mr. Wang said is of course a possibility, whether it is elopement or something else, it belongs to the scope of temptation; Then in addition to the temptation, there may also be the possibility of coercion, and Miss Yin's motive for leaving is not out of these two. ”

Lu Yuanzhi has been following Qin Lin for a while, and he has a lot of experience after his guidance, so he immediately reacted: "In this way, in addition to the male surname, the murderer may also have a female surname?" ”

"It can't be ruled out," Qin Lin nodded, if the female surname took advantage of some secret secrets heard in the boudoir to threaten her, Miss Yin was also likely to miss the night to have a private meeting with her and be killed.

"General Qin is like a god in judging the case, and someone Bai is really impressed!" Bai Hao bowed deeply to Qin Lin, his expression was by no means sycophant, but out of sincerity.

Although on the surface, it seems that the real murderer has not been locked down, and the scope of the suspect has not even been demarcated, but in fact, Ying Tianfu, who has an experienced detective, knows that Qin Lin has taken the most important and critical step on the road to solving the case, and it is also a step to decide the surname!

In this kind of murder case, the most difficult thing is to determine the quality of the surname, whether it is an acquaintance who committed the crime, or whether it is a wandering person who committed the crime; if it is the latter, the investigation work will become unprecedentedly difficult -- the industrial and commercial economy in the south of the Yangtze River is developed, and there is frequent movement of people of all colors, and the road guidance system of the Ming Dynasty has long been abolished.

And now Qin Lin has advanced the case to the most critical step, no matter whether the reason why Miss Yin went out was coercion or inducement, the criminal must know her, so the surname of the case was firmly nailed to the acquaintance who committed the crime.

Taking this conclusion as a starting point, investigating Miss Yin's interpersonal relationships can greatly narrow down the scope of suspects - if Qin Lin's previous investigation work was looking for a needle in a haystack, then now he is looking for stones in a pond!

Lu Fatzi, Bai Hao, Xu Xinyi, and everyone were all gearing up, looking at Qin Lin eagerly.

At the moment of the big case, Qin Lin gave an order: Bai Hao and his subordinates quickly investigated and transferred internally and externally, and searched for clues between Yin's family members and servants through various channels, focusing on who Miss Yin had close contacts with, and the clues pointing to the murderer were likely to be among them; Han Feilian returned to the Gengzi office to sit, and Niu Dali led the small banner of his own soldiers to be stationed in Qin Lin's mansion, ready to go out at any time. All the school captains wore civilian clothes and went out, led by Lu Yuanzhi and You Guizi, two people who are familiar with the ecology of the market, to investigate clues in the gambling stalls of the restaurant tea shop, focusing on asking Sister Yao about the guests who have "special habits" in that area and may have intersections with Miss Yin in life.

didn't mention Xu Xinyi for a long time, and the eldest lady came up anxiously, pointed to the tip of her beautiful nose and asked, "I, what about me?" Qin Lin, Miss Ben is no worse than you in solving the case! ”

Qin Lin thought about it for a while, and also gave her the task: Xu Xinyi inquired about the news among the ladies and daughters of wealthy families who had a relationship, to see who had more contacts with Miss Yin, and whether anyone had heard of who Miss Yin liked and what she didn't know**; In addition, Chang Yinxu was notified and asked to inquire about the same content among the gentlemen in Nanjing.

"Don't worry, Miss Ben!" Xu Xinyi patted his chest, and suddenly his plump chest was turbulent, and Qin Lin was a little dry.

Miss Xu took care of it without thinking: "It's Xiao Chang, I'll go and talk to him, he will definitely do this with his heart - but in the end, Miss Ben must find out the murderer, hahahaha......"

I hope so! Qin Lin smiled reluctantly.

He doesn't have the always good self-confidence of Miss Xu, on the contrary, he still has great worries in his heart.

This case has killed two young girls, not only a serial murder case, but also a sign of escalation of crime!

Modern criminal investigation believes that a serial killer, also known as a serial murderer, is a case in which one or more killers kill the victim one after another, and ordinary people always think that the appearance of a serial killer must be like a madman or a madman, and his moral character is inferior, but in fact he may not, most of the serial killers are no different from ordinary people, and even very charming, and have noble feelings or strict sense of morality, and even there are many highly educated people, which also gives people the illusion that they are easy to get close to. Simply put, the vast majority of serial killers barely associate them with their actions until they are caught.

And the reason why the serial killer commits the crime is mostly to satisfy the pervert in his heart**, this kind of repression and distortion ** is temporarily relieved through crazy killing, and the guilty pleasure of killing itself has a positive feedback on his psychology, which makes his psychology further distorted and perverted, and there will be an escalation of crime!

It's like a drug addiction, it only takes 0.3 grams to satisfy at first, followed by 0.5 grams, 0.8 grams...... In the Yuhuatai case, the criminal only abandoned the victim in the wilderness and froze to death (it is very likely that he was drugged), and the process was relatively slow and peaceful, and there was also a sense of "luck" in terms of psychological state.

But after the real death of the victim Duan Ping, the news had already spread, and the criminal was stimulated by the positive feedback of the surname, and the psychology was further distorted, so in the second case, Miss Yin's drowning was more rapid, thorough and irreversible than Duan Ping's freezing death, abandoning the person in the cold and windy wilderness to pushing into the water, the criminal method became more direct, and the feedback to the criminal from a psychological point of view was also greatly improved.

If the murderer is not found soon, there is a good chance that his crime will escalate further!

When Qin Lin was worried, Wang Shizhen was not happy, he was up and down in the officialdom, and now the position of Ying Tianfu Yin is also flattering Zhang Juzheng, now Zhang Juzheng is in power, the new policy is in full swing, and the four seas are singing Taiyue Xianggong is Guan Zhong's resurrection, Zhou Gong came to the world, and he was born at the juncture of the New Year in the seventh year of Wanli, and such a serious crime occurred in Nanjing City, the capital of the Ming Dynasty!

There are two cases that have happened now, Duan Ping is a maid, although Miss Yin's family is rich, she is still just a businessman, if the case is not solved, the next accident will happen to the daughter of a certain dignitary, there will be a snowflake-like bullet flying to the Beijing Division, and he should be the end of Tianfu.

Of course, as Qin Lin, the deputy of the Jinyi Guard, who patrolled the streets to arrest and annihilate evil, was also responsible for this, and the two people, the old and the young, the one literate and the one martial, really became a grasshopper tied to a rope.

"If there is any other daughter of the boudoir who was drugged and drowned," Wang Shizhen paused, and said with a wry smile: "General Qin solved the Yangzhou case, Jane is in the emperor's heart, and it is still easy to say; I'm afraid the old man will have to hang up his crown and leave. ”

"Freeze to death, drown?" Qin Lin raised his eyebrows, and let out a long breath: "If there is another case, I'm afraid it's more than that......"
