Ling Guodong arranged for people to spray luminol on a large area from the place where the blue-green fluorescence was found, and asked the appraisers to shoot it in time with a long-exposure camera, because the time for luminol to show blood stains was very short, and it would only last for more than 30 seconds at most.

Yun Duruo and I stood in the room, slowly opened our mouths, with the detection of luminol spray, we saw a large area of blue-green fluorescence in the dark room, the living room part is still less, the more we go to the bedroom, the area and distribution of fluorescence is getting larger and larger, which means that this room used to be full of blood, but it was wiped clean and wiped out all the truth.

I'm probably the most professional person in the room when it comes to blood jets, and my heart slowly lifts as I look at the fluorescent light scattered everywhere in the bedroom.

"There was also fluorescence on the wall, indicating that blood had been splashed on it." I pointed to the place next to the bed where the fluorescence was strongest and the largest was largest. "This should be the first scene of the crime, but there is no way to determine who the blood is, but most likely it should be Mu Hanzhi, she should have been killed here at the time, judging from the blood splashed on the wall, she should have been attacked by a heavy object, so as to cause the blood to splash like this."

Yun Duruo's face was solemn after hearing this, he looked at the place I was pointing, and then looked back at the opposite side of the bed, and said lightly with a frown.

"Vase! Why was there only one vase left in the room that was originally a pair of vases when Mu Hanzhi died, because the vase was the murder weapon, someone attacked Mu Hanzhi with a vase, and took the vase afterwards to destroy the evidence. ”

"Yes! That's what I thought, too. I nodded, and said in a gloomy voice, pointing to the fluorescent distribution. The distribution of these blood stains is very natural, which shows that Mu Hanzhi did not resist when he was killed, and it is not difficult to find through the photos of the scene investigation that year that there was no trace of a dispute and fight in the room, and Mu Hanzhi was killed completely unprepared. ”

"I have also read Mu Hanzhi's file, it records that Mu Hanzhi has a withdrawn personality and few people come and go, and this is still a bedroom, who can make Mu Hanzhi so relieved and bring him to the bedroom?" Ling Guodong, who was squatting on the ground, stood up and asked suspiciously.

I suddenly remembered that Liu Yuewu told me and Yun Duruo before he died that the day Mu Hanzhi jumped off the building happened to be Mu Xiaoxuan's birthday, and Mu Hanzhi happily told Liu Yuewu that Mu Xiaoxuan's father was coming that day, and the person who could let Mu Hanzhi take him into the bedroom defenseless may be this mysterious person who has never shown his face.

According to this inference, even Mu Hanzhi's motive for being killed is slowly becoming clearer, not that Mu Hanzhi doesn't want to disclose who the man who ruined her reputation is, but that this man is deliberately concealing his identity, and even kills Mu Hanzhi in the end to keep it a secret.

"There are footprints!" Colleagues from the Forensic Services Bureau shouted loudly in one place.

Under the development of luminol spray, a pair of footprints appeared in front of our eyes, which should be the footprints of a man, and for the first time, direct physical evidence was extracted from the scene of Mu Hanzhi, and everyone in the room was very excited, but it only lasted for a few seconds, and this excitement turned into shock.

The footprints that appeared under the luminol spray were not just a pair, slowly, the second and third pairs until the appearance of the fourth pair of footprints, scattered in the bedroom, twenty years ago these were bloody footprints, sealed for twenty years and were revealed, in addition to Mu Hanzhi and Mu Xiaoxuan in the room at that time, there were four other people!

Yun Duruo and I have been assuming that it was the mysterious man who killed Mu Hanzhi in order to disguise his identity, but now it seems that the case is not as simple as we thought, there were four people in the room on the day Mu Hanzhi died, judging from the distribution of footprints, it is likely that these four people conspired to kill Mu Hanzhi and Mu Xiaoxuan together.

The on-site identification and analysis colleagues told Ling Guodong that the bloodstains found in the room were consistent with Mu Hanzhi's after inspection and verification, but no bloodstains were found on Mu Xiaoxuan's side now.

"It seems that Mu Hanzhi was killed in this room." Ling Guodong sighed and said to Yun Duruo and me. "Judging from the footprints at the scene, there are Mu Xiaoxuan's footprints, but there are no traces of his blood, at that time he should have witnessed the whole process of Mu Hanzhi being attacked to death, but he was not killed at that time."

"Jiang Ju also said that when he received the alarm and rushed to the scene, he also saw Mu Xiaoxuan crying on the roof, indicating that Mu Xiaoxuan was still alive at the time, which is consistent with the inference of the traces at the scene." Yun Duruo nodded and said.

"Mu Hanzhi's body was corroded by sulfuric acid to a much more serious extent than Mu Xiaoxuan, and the witnesses at the scene of the crime at that time confirmed that they saw Mu Hanzhi pouring sulfuric acid on him on the roof of the building, if Mu Hanzhi was dead at that time, then it was the murderer who poured sulfuric acid, and it was this person who pushed Mu Xiaoxuan downstairs." I took a deep breath and said in a heavy voice.

"Why can you kill Mu Hanzhi in the room, but you have to keep Mu Xiaoxuan?" Ling Guodong asked puzzled.

Regarding this point, I think Yun Duruo and I both have the same thoughts, keeping Mu Xiaoxuan is to arrange the illusion of Mu Hanzhi's suicide, and the witnesses at the scene all heard and saw Mu Xiaoxuan's cry, indicating that Mu Xiaoxuan was alive, and also saw Mu Hanzhi, the witnesses below did not know that Mu Hanzhi was dead at this time, and they would have preconceived ideas that Mu Hanzhi was also alive when he was on the roof.

Witnesses who saw Mu Hanzhi pouring sulfuric acid on Mu Xiaoxuan's body, would subjectively judge Mu Hanzhi's insaneness, which would also lay the groundwork for Mu Hanzhi's suicide by jumping off the building, a woman who could not bear to hurt and kill even her own children, it can be seen that she has completely had a mental breakdown, even if she jumps off the building, no one will trace the reason behind the suicide, everything is simply attributed to Mu Hanzhi's madness!

This also solves a problem that has been entangled with me for a long time, Liu Yuewu told me and Yun Duruo, Mu Hanzhi takes Mu Xiaoxuan very seriously, it is completely her sustenance, and he specially went to visit Liu Yuewu because of Mu Xiaoxuan's birthday, and asked him to make the bean paste buns he liked to eat when he was a child, how could Mu Hanzhi bear to hurt Mu Xiaoxuan.

In fact, I didn't figure out why I used sulfuric acid before, but now I understand what it means.

"Cover up the time of the crime and the time when Mu Hanzhi was really killed, and prepare for the illusion that Mu Hanzhi jumped off the building to commit suicide later." Yun Duruo said sharply beside me.

"Yes, Mu Xiaoxuan deliberately did not kill in the room in order to arrange the illusion of suicide, but the murderer knew that even if he committed suicide by jumping off the building, the forensic doctor would conduct an autopsy to determine, and at that time, the forensic doctor would quickly find out that Mu Xiaoxuan and Mu Hanzhi died at the wrong time, thus overturning the layout of suicide." I rubbed my forehead and said slowly.

The layout of the murderer is actually very simple, it is not easy to control Mu Hanzhi, but it is much simpler to control a child, pushing Mu Hanzhi from the upper floor will make people doubt Mu Hanzhi's death, so the murderer needs witnesses to prove the elaborate suicide case.

But Mu Hanzhi will resist and once the flaws are exposed in front of everyone, his previous efforts will be wasted, so Mu Hanzhi must be eliminated first, and in order to cover up Mu Hanzhi's death time, Mu Hanzhi's skin must be destroyed and corroded, which can perfectly make people believe that Mu Hanzhi and Mu Xiaoxuan fell to their deaths together.

"There is actually another reason why you chose to commit suicide by jumping from the top of a building." I said lightly.

The time for luminol spray to develop bloodstains is very short, it will only last for thirty seconds, and it must be in the dark to appear, fortunately, Ling Guodong arranged for someone to take pictures of the bloodstain distribution at the scene with a long-exposure camera in advance, after completing all the bloodstain survey, I turned on the light The room was bright again, and the fluorescence distributed around the room disappeared in front of our eyes in an instant, like a buried secret that was hidden in front of everyone's eyes for twenty years.

"I know!" Yun Duruo said to me confidently. "The direct cause of Mu Hanzhi's death should be caused by a heavy object, but such a wound will be found during the forensic autopsy, in order to cover up this wound, the best way is to create the illusion that Mu Hanzhi fell to his death, and it is easy to hide the wound in the body with multiple serious injuries to the bones of the whole body."

"But you still overlooked a very important link!" I looked at Yun Duruo and said.

"Yes...... What is it? Yun Duruo asked suspiciously.

"Who wrote the autopsy report?" I didn't hesitate to ask.

"Xiao Bo......" Yun Duruo also realized something when he said this. [妙 * 筆 * 閣 ~] miao pen ge update fast

With Xiao Bowen's autopsy skills and experience, how could he not tell whether it was the wound caused by the heavy object attack or the injury caused by the fall, but the final identification of Xiao Bowen in the autopsy report was suicide, which shows that Xiao Bowen did not find the real fatal injury in the end, but how could a forensic authority make a mistake.

"Do you remember that Zhou Baiman said that she once saw Mu Hanzhi arguing with a man, although she didn't see the man's face clearly, but she remembered the smell of the man." I walked back and forth a few steps and asked lightly.

"Formalin! The man should be a medical worker or someone who has access to medicine. Yun Duruo blurted out.

"It should be a very professional medical practitioner, and the technology and experience are extraordinary!"

I told Yun Duruo with certainty that there was only one reason why Xiao Bowen could make a wrong forensic judgment, the murderer knew very well how to cover up the wounds, indicating that this person knew the formation and characteristics of various external injuries, and in order to prevent flaws from being found during the autopsy, maybe this person also deliberately handled Mu Hanzhi's corpse, so that in the end, even Xiao Bowen didn't notice it.
