If Liu Jing did not kill Du Juan and He Shuangxi, but he knew the names of Tao Qiangsheng and Tao Lixin, it would be unexplainable.
If it is true that he killed these two people, and it was his first time offending, but within a few days after killing Du Juan, he could respond to the police interrogation very naturally, this can only show that Liu Jing is extremely talented and powerful in the matter of killing. Incomparable psychological quality is inherent.
But this kind of one-in-a-million "martial arts genius" is really rare, and has been rare for many years.
In addition, Du Juan was not the first person Liu Jing killed, which can also explain this. The psychological quality of criminals is the same as their methods of committing crimes. They often continue to upgrade with the increase in the number of crimes committed and the accumulation of criminal experience. The strong psychological quality displayed by Liu Jing often means that he is not a first-time offender.
Yang Feng and Wu Xiaojun came to their senses after thinking about it for a while, and unanimously believed that the last option was more likely. This Liu Jing, who seems to be "useless" in life, relationship, and career, is most likely to be secretive and outstanding in the matter of murder, and is ahead of his two sisters.
Wang Xing suddenly had a second question: "Even though it was not the first time Liu Jing killed Du Juan, I only came to ask him during the day. As soon as I left at night, he started planning the second time. He murdered He Shuangxi on the second day and set the murder location in his own home. His courage...isn't he too bold?"
"Besides, the older Jianghu gets, the less courageous he becomes. If I were him, I would have to wait until Du Juan's disappearance is calmed down, right?"
Wu Xiaojun immediately put forward a different view:
"You have forgotten the text message Liu Jing sent to Du Juan using Du Juan's mobile phone. He said in the text message that Du Juan had eloped with He Shuangxi. This was indeed the best lie to conceal Du Juan's murder, but it also had a consequence , that is, He Shuangxi must die immediately, and the sooner the better, otherwise as long as Du Wen knows or sees He Shuangxi still appearing in Shashi, this lie will be broken. "
"So, I think it's not that Liu Jing's courage is so lawless and unbelievable, but that she was forced to go to a dangerous place and had to risk everything and make a desperate move."
"Besides, the most dangerous place is the safest, and the most dangerous time is also the safest. For those murder cases that occurred next door to the police station, the two accomplices chose to meet at the door of the public security bureau before committing the crime. After killing the person, they rented a house next door to the police station, and even They set up a stall right in front of the police station. You may have heard of these ridiculously brave criminals, even if you have never seen them."
Wang Xing thought about it and thought that he might be paranoid on this point.
Yang Feng did not comment on this, but he had no intention of continuing to interrogate the three siblings overnight:
"We'll wait until the physical evidence inspection report comes out. These three siblings are rushing to bear the blame and are inextricably linked to the deaths of the two Yuan brothers."
"Although there is not much difference in their confessions about killing the two brothers, each of them used different tools to commit the crime. This should be able to identify who among them is the real murderer from the autopsy."
"Once we have this situation under control, we will be more confident when we pry open their mouths with solid evidence and comprehensive information."
Wang Xing and Wu Xiaojun expressed no objection to this.
The next day.
The forensic doctor showed the two DNA test reports in Yang's hand:
"Following the instructions, we went to Liu Jing's home and found two residual blood on the legs of his sofa."
"One of them is located in the cracks of the wooden legs of the sofa. The blood in this place is not very obvious. It should be that when the murderer cleaned the crime scene, the water mixed with blood soaked into the wooden legs of the sofa and remained in the wood cracks. We I cut off several legs of the sofa and took them back to the police station for testing, only to discover the blood remaining in the crack of one of the wooden legs."
"After DNA testing and analysis and comparison with the DNA of He Shuangxi's father, it can be determined that this blood belongs to He Shuangxi."
After a pause, the forensic doctor added: "He Shuangxi is an only son, and his grandparents passed away five years ago, so this blood does not belong to the second person."
Yang Feng nodded and asked, "Where is the other blood stain? Does it belong to Liu Jing?"
Unexpectedly, the forensic doctor shook his head: "Another blood stain is on the wooden frame at the bottom of the sofa. It is more obvious, but it is difficult to find if you don't turn the sofa over. After DNA comparison... this blood stain does not belong to He Shuangxi does not belong to Liu Jing either."
Yang Feng's eyelids suddenly twitched: "Is that Liu Yuanyuan or Liu Zhaodi?"
If this is the case, then all previous analysis and speculation must be overturned.
The forensic doctor once again gave an unexpected answer: "None of them..."
"Yes! Lao Qin, stop being so pretentious and tell me the answer directly."
However, Lao Qin put the two reports directly into Yang Feng's hands: "You can see for yourself... It's not that I want to show off, but we are not sure who the blood here belongs to, so we can only go to Liu Jing's house to continue. Extract samples for DNA comparison."
Yang Feng opened a DNA test report in his hand. After taking a closer look, his face was full of disbelief: "Parent-child relationship? The other blood belongs to Liu Jing's child? This is impossible. Liu Jing's child is 5 Years old, a 7-year-old, no matter who it is, it is impossible for him to be the murderer of He Shuangxi."
Lao Qin looked at him very dissatisfied: "Why are you so excited...Who said that the person who left this blood stain must be the murderer? Children are jumping up and down at home all day long, touching here and there, and putting their hands under the sofa. , accidentally scratched the skin, and it is normal to leave blood stains on the wooden frame at the bottom of the sofa."
After a pause, he added: "Besides, the DNA test report only said that there is a father-son relationship between the owner of this blood stain and Liu Jing, but it didn't say that it must belong to Liu Jing's child, right?"
Yang Feng immediately listened attentively: "Old Qin, please continue."
"When I said that He Shuangxi was an only son, I specifically emphasized that his grandparents had passed away five years ago, right? This is because DNA can only prove whether there is a father-son relationship, but it cannot determine who is the father or who is. It’s a son.”
"The DNA sample compared with the bloodstain found in the crack of the wooden foot came from He Shuangxi's father. After testing and comparison, it was proved that there is a father-son relationship between the two. But if this bloodstain is from He Shuangxi's grandparents, You will also get this result if you stay. Do you understand?"
Yang Feng and others immediately nodded like chickens pecking at rice.
"So, the blood stain on the wooden frame at the bottom of the sofa may belong to Liu Jing's child, or it may belong to Liu Jing's mother." ap.
"If Liu Jing's wife Du Juan is still alive, DNA samples can be taken directly from her. After comparison, if there is a parent-child relationship between the two, it can be determined that this blood stain was left by Liu Jing's child. If it is completely If it doesn’t match, then there is no doubt that it belongs to the old lady of the Liu family.”
"But the cuckoo was gone, so I had to go to Liu Jing's house to collect DNA samples from his old lady and two children, and compare them with this blood stain one by one."
Yang Feng suddenly thought of another possibility and suddenly felt his scalp numb: "Old Qin, the blood stains on the wooden frame at the bottom of the sofa and He Shuangxi's blood stains in the cracks of the wooden feet, can you confirm that they were left on the same day?"
"I know what you mean. If this blood stain is confirmed to be left by the old lady of the Liu family, and it coincides with the time when He Shuangxi left the blood stain, then the old lady will be suspected of committing the crime."
"Our people also sawed off the sofa tripod and carefully conducted tests. We can only determine that it was left at roughly the same time as He Shuangxi's blood stains. We cannot confirm whether they were left on the same day."
This conclusion is enough to include the old lady of the Liu family as a suspect in the murder of He Shuangxi.
The old lady witnessed with her own eyes the affair between He Shuangxi and Du Juan, and she doted on Liu Jing, so there was no problem with the motive of the crime.
The four members of the Liu family, if picked at random, would have sufficient motives for committing crimes. This is damning.
But an old lady in her seventies or eighty could kill He Shuangxi alone? If she and Liu Jing committed the crime together to kill He Shuangxi, it would be possible. Afterwards, the old lady would call Liu Zhao
When Liu Zhaodi disposed of the body, Liu Zhaodi would not ignore it.
Judging from the information obtained through various investigations, although Liu Zhaodi does not want to see her brother, she is not dissatisfied with her mother.
Logically speaking, a loving mother often loses her son, and anyone with a discerning eye can see that Liu Jing's behavior of "gnawing at the old and gnawing at her sister" is inseparable from the old lady's pampering, pampering, and preference for Liu Jing since she was a child.
Since Liu Zhaodi didn't want to see her younger brother, she should also have some complaints about her mother. But she "hated the standard but not the original" and only hated her brother for being "useless", but she didn't blame the old lady for "spoiling" him. This is really rare.
Looking at the DNA test report in his hand, another question suddenly popped up in Yang Feng's mind:
In the confessions of the three siblings of the Liu family, there was no concealment or distortion of the fact that He Shuangxi was beaten to death with a cane at Liu Jing's home. This was because they, or some of them, knew that even though the blood stains at the crime scene had been cleaned, Qingshui The wooden legs of the sofa were soaked with blood. Even after three years, the police were able to extract the blood through technical means.
Therefore, these three siblings did not dare to conceal or distort this.
There is no doubt that among the three siblings, the one most likely to know this is Liu Yuanyuan, a doctor.
The problem is, since Liu Yuanyuan knew this, why didn't she just ask Liu Jing to replace the sofa or even replace the floor at home?
Soon, Yang Feng had the answer in his mind, and at the same time, his scalp was numb again because of the answer, and he thought that there was no need for Lao Qin to compare and verify who the blood stains on the wooden frame at the bottom of the sofa belonged to.
