"This craniocerebral impact injury resulted in severe craniocerebral injury, enough to cause death. This was the fatal injury to the two deceased persons."
"So, based on the above analysis, combined with the characteristics of the deceased's cranial impact injuries, the two deceased should have wanted to escape through the window, but accidentally fell from the window, injuring their occiput and causing severe craniocerebral injury and death."
"The handprints on the window eaves can prove that the fingerprints were left by the two deceased people. The footprints on the wall and the window eaves on both sides exactly match the size of the soles of the two deceased people. This shows that the deceased had been on the window sill during his lifetime. "
"The hands of the two deceased people had small scratches and rust. The window rails on the north wall were made of rusty rebar. Traces of fresh wiping were also found on the rebar, as well as some residual blood stains. DNA testing Comparison confirmed that these blood stains were also left by the two deceased persons."
"There were contusions and lacerations on the deceased's occiput. There were fine gravels in the wounds, which were basically the same as the gravels on the ground. I have emphasized this point before. This shows that after the deceased accidentally fell from the window sill, the occiput should have hit the ground first. Cause death."
"And among the flakes on the deceased's back, there are many indentations similar to small stones. What does this mean?"
"Spots on corpses can often reflect traces of the shape of objects in contact with them. For example, if a person dies with his bare arms on a mat in the summer, there will be grid-like indentations on the back that are unique to the mat. But there is a prerequisite, that is, the deceased is dead. I had to lie on the mat for quite a while afterwards."
"The gravel-like indentations on the backs of the two deceased persons indicate that they lay on the ground for a long period of time after death without being discovered, and the bodies were correspondingly untouched during this period of time."
"In addition, the two deceased people had long dog chains around their necks, and their hands and feet were shackled, but their movements were not completely restricted."
"Based on all this, it is not difficult to imagine that the two deceased people suffered humiliation and abuse during their lifetime, and they wanted to escape after the abusers left."
"But the door was locked, and the other end of the dog leash was locked at the bottom of the wall under the window. The length of the dog leash was not enough for them to move to the door, but it could barely allow them to find a way to climb up the window sill."
"Perhaps they thought that one person was not strong enough, so the two deceased climbed up the window and shook the rebar with both hands, trying to break the window and escape. After all, the rebar looked rusty and not very thick. Two adult men Together, it might be possible to shake it out."
"At the same time, as long as a steel bar is shaken out, you can use it to break the dog chain. Apart from a pile of straw in the corner, there are no other objects in the pigsty, let alone any hard objects that can be used to break the dog chain."
"It may be that they used too much force or were not careful. After all, their hands were shackled and their movements were extremely inconvenient. In short, some of them fell from the window. The person was falling from a high place. In an instant, in order to protect himself, he would subconsciously reach out and grab, and he might have grabbed another person and pulled him off the window sill."
"Unfortunately, both of them landed on their pillows and died on the spot. They did not even turn over. It was at least 12 hours before the bodies were turned over. As a result, gravel-like indentations were formed on the backs of the bodies. "
Lao Qin's analysis and determination were based on physical evidence. Everyone believed that the truth about the death of the Yuan brothers had been basically restored. But the question was: since the two brothers fell to death accidentally, why did the three Liu brothers rush to admit it? Did you kill them yourself?
After a moment of silence, Yang Feng expressed his opinion:
"The two brothers of the Yuan family died from a slip and fall. This is the result that Lao Qin obtained based on the autopsy and various traces at the crime scene. But for the third brother and sister of the Liu family, will they know this result?"
"They definitely don't know. If they knew that the Yuan brothers fell to death by themselves, they would definitely not rush to blame themselves."
"Liu Yuanyuan is a doctor. If she had seen the bodies of the Yuan brothers in time, she might have suspected the cause of their deaths. But when the dismemberment occurred, she most likely had not seen the bodies of the two brothers."
Then, Yang Feng changed the subject:
"There is no doubt that the three Liu siblings were not present when the two deceased attempted to escape through the window, including when they fell to the ground and died."
"In the confessions of the three siblings, they all said that they had abused the Yuan brothers, either beating them with belts, digging them with rakes, or hitting them with bricks. This is also true."
"At the same time, they all said that they used different tools to kill the two brothers. Liu Yuanyuan said that she smashed them to death with bricks, Liu Zhaodi said that she used a rake, and Liu Jing said that she beat them to death with a belt. "
"Why does this happen?"
"I think it's probably because they each used their own killing tools to torture the two deceased people. After that, they went back to the house to rest. The next day, maybe Liu Zhaodi, maybe Liu Jing, or It was the two of them who pushed open the door of the pigsty and found out that both Yuan brothers were dead. What would they think at this time?"
"Do you think that your previous abuse caused their death?"
"In their eyes, the hand and foot shackles of the two deceased people were not opened, and the dog chains around their necks were also there. The windows were 2 meters high from the ground, and the various traces on the window rails and sills were not immediately visible. Come into their sight. All these indicate that nothing unusual has happened in the pig pen, and no outsiders have entered."
"So, in their view, it was only their three siblings who caused the death of the two Yuan brothers."
"We don't know when Liu Yuanyuan saw the body, and we don't care about it for now."
"The important thing is that these three siblings have this consensus. They all believe that they killed the Yuan brothers, or that their joint abuse led to the death of the Yuan brothers, and they all believe that they are all guilty of this. It was only natural that he would kill one person instead of killing the whole family."
Wu Xiaojun and Wang Xing expressed no objection to this, and Lao Qin just listened without saying anything.
Before the new round of interrogation began, Yang Feng received the latest investigation status about Liu Yuanyuan:
After verification with Shang Biao, Liu Yuanyuan was indeed separated from him for a day or two from July 1 to 5, 2004, saying it was because she had to take care of her sick female mentor.
On the other hand, the local police came to visit and found that Liu Yuanyuan's mentor had passed away.
It seems that this part of Liu Yuanyuan's confession cannot be verified by her mentor, but judging from Shang Biao's feedback, this part of her confession must be true, which means that she did use this excuse to briefly leave Shang Biao. After a day or two, he went back to Shashi and killed Zhou Xiaolu.
However, one of the many photos sent by the local police at the same time completely denied this part of Liu Yuanyuan's confession.
Although Liu Yuanyuan's mentor has passed away, her house is still there, and her daughter, Ms. Tang, lives in it.
Ms. Tang recalled that her mother mentioned that in July 2004, her mother did suffer from a serious illness, but she, the daughter, was not around, and her father had passed away long ago, so several female students of her mother discussed each day. Two people took turns taking care of her for a day or two, but Ms. Tang did not know who these students were or what their names were.
It was precisely because of these students' meticulous care and concern that my mother was so moved that she secretly took pictures of these female students busy in the house, hoping to keep these beautiful pictures and memories. .
These photos were naturally provided by Ms. Tang to the local police, who scanned them and forwarded them to the Shashi police.
The photos were taken with an old-fashioned digital camera, and the time display was set when taking them.
One of the photos suddenly showed Liu Yuanyuan. Although the photo only captured Liu Yuanyuan's profile, it was enough for people to identify her appearance.
The time on this photo shows July 2, 2004, which was the day Zhou Xiaolu was murdered.
In addition to Liu Yuanyuan, there is another girl in the photo. Behind the photos were written "Liu Yuanyuan Zhu Xiaojuan". Zhu Xiaojuan should be the name of the other girl.
Yang Feng looked at the photo in his hand and immediately asked someone to get in touch with Zhu Xiaojuan and asked her if Liu Yuanyuan had left midway when she and Liu Yuanyuan were taking care of the female tutor.
Zhu Xiaojuan recalled on the phone that Liu Yuanyuan had not left on July 2. She also said that their group went to the female tutor's home at 8 o'clock in the night on July 1 and did not leave until 8 o'clock in the morning on July 3. Another group of students came to "take over" the class.
In other words, on July 2, Liu Yuanyuan did not have the time to commit the crime of killing Zhou Xiaolu.
It has to be said that Liu Yuanyuan is an out-and-out master at lying and forging confessions. At this point, she almost succeeded in getting through with a half-truth and half-false lie.
Since Liu Yuanyuan admitted that she killed Zhou Xiaolu, the police would naturally have to verify her confession, and the two people involved in this part of her confession, namely Shang Biao and the female mentor, would definitely become the targets of police questioning and verification.
The female mentor has passed away, which Liu Yuanyuan may have known for a long time.
Therefore, she also knew that the police's verification interview could only find Shang Biao, but was destined to be unable to find the female mentor.
During the verification interviews with Shang Biao, it could only be proven that Liu Yuanyuan had indeed separated from him from July 1 to July 5, 2004, and the "excuses" used were consistent with what Liu Yuanyuan herself stated. These circumstances were only It will make the police believe that Liu Yuanyuan's confession is true.
But Liu Yuanyuan never expected that the female tutor secretly took photos of every student who took care of her.
Although Liu Yuanyuan was not the real culprit who murdered Zhou Xiaolu, the identity of the real culprit is not difficult to guess.
Since this woman wanted to take the blame for Zhou Xiaolu's death, she undoubtedly wanted to take the blame. Who would make Liu Yuanyuan willing to take the blame?
