In the afternoon, the autopsy room was very quiet, Liang Zhijie leaned against the wall with his eyes lowered, and Li Fei leaned in front of the forensic doctor to ask him about the autopsy of the deceased in the morning.

"The cause of death of the two children was relatively simple, it was an excessive inhalation of natural gas in their sleep." The medical examiner produced a test report: "The ingredients of milk and some tranquilizers were detected in the stomachs of the two children, which is why the two children did not have any struggle at the time of the accident." Under the action of tranquilizers, they slept to death. ”

"Who would drugged the milk of two children?" Li Fei looked at the test report: "The feeding time of the two children is around half past nine in the evening, and Jiajia has not been sent back to the Zhu family at this time. There are only two adults in the family, one is the child's grandmother and the other is the child's mother. Grandma has no reason to harm her grandson, let alone mother. ”

"Of course, the child's mother would not harm the child, and she did it because she did not want the two children to see or hear what happened that night." The medical examiner pulled out two other test reports: "In the refrigerator of the deceased, the remaining half bottle of milk was found, and complete fingerprints were extracted from the bottle." Through fingerprint identification, it was confirmed that it belonged to the child's mother. On the child's mother's mobile phone, we also found the latest payment record, and locked a nearby supermarket chain through the recipient. Through the surveillance video in the supermarket, it was confirmed that the bottle of milk was purchased by the child's mother before her death. ”

After a pause, the medical examiner continued: "On the dining table, we found two glasses, on which residues of milk were detected, the composition of which was exactly the same as the bottle found in the refrigerator. Judging from the furnishings of the Zhu family, Zhu's mother, including the mother of two children, does not look like that kind of sloppy person, and the fact that the milk cup is not cleaned is worth paying attention to. ”

"The person who washes the milk is unsettled." Liang Zhijie took the test report: "She knew that something happened at night!" Are there any other discoveries other than milk? ”

"Two children have been moved." The medical examiner produced another test report: "Both children were dragged to the kitchen, and on the back of the child, some oil stains were found, which matched the oil stains on the kitchen floor. ”

"It won't be the mother of the child!" Li Fei gave his own judgment: "The child's mother doesn't have to do this kind of thing. ”

"It's Jiajia!" The forensic doctor sighed: "On her, we also found similar stains. Although it is wrong to guess that a little girl is wrong, all kinds of evidence at the scene show that she did it. As for why she dragged her two younger siblings to the kitchen, I think she was doing it for them to get more gas. ”

"How old is this kid?" Li Fei's face was full of shock: "Unless she admits it herself, I will never believe that a little girl has such a vicious heart." ”

"I don't believe it either, but she put a mask on herself and took multiple precautions in addition to the mask." The medical examiner picked up a mask: "This was found in a trash can near the coffee table, and there were only Jiajia's fingerprints on the mask." You are all familiar with this kind of mask, and it belongs to the kind with a high level of protection. In order to avoid inhaling a large amount of natural gas by herself, Jiajia padded something inside the mask and wrapped a towel around the mask. ”

"If Jiajia did all these things, then why didn't she run away?" Li Fei asked: "Staying at the scene and staying with the victims can indeed wash away your suspicions, but at the same time, you may lose your life." Jiajia, she wouldn't have thought of this, right? ”

"She thought about it, but she was stuck at home." Fa took out a few photos: "There is a situation at the police station in the jurisdiction, you should not have taken care of it." ”

"This door lock is-" Li Fei handed the photo to Liang Zhijie: "It's not a normal unlock, it's a forced opening!" ”

"Isn't that how locks are picked?" Liang Zhijie has never found a lock picking expert, and he doesn't know much about unlocking.

"Of course not, I have experience with unlocking." Li Fei scratched his head and said, "Really, I'm very experienced. I always forgot to bring my keys when I first changed the locks at home, and it is no exaggeration to say that on average, I had to go to the locksmith every two days. The master is particularly skilled in unlocking, and it is enough to gently dial it twice with a tool, like the situation in the photo, nine times out of ten the door lock is broken. ”

"It was vandalized." The forensic doctor pulled out one of those photos: "These photos are all sent from the police station in the jurisdiction, and I personally think that Jiajia was used by someone." She is a little girl, no matter how smart she is, she can't think of this, and even if she thinks of it, she may not have the courage to implement it. There must be an adult behind the commission of these crimes. You've seen the scene, we've seen the scene, and to tell you the truth, there's not much evidence that can be found at the scene. It is impossible for a young girl who has never committed a criminal act to this extent for the first time. ”

"Like our opinion, we also think that there is an inside story about Jiajia's sudden return home." Li Fei blinked his eyes deliberately: "Has the autopsy report of the child's mother come out?" ”

"The deceased had minor skin contusions on both armpits and skin abrasions on the soles of his feet, but other than that, no other injuries were found." The medical examiner looked at the autopsy report in his hand: "There was slight bleeding from multiple internal organs, and the symptoms were a bit like suffocation. There are impurities in the trachea and lungs, like drowning but not drowning. ”

"Was it electrocuted?" Li Fei's eyes rolled, and he thought of the electric current spot mentioned earlier: "Is it possible that the current is causing cardiac paralysis?" ”

"It's possible!" The medical examiner returned to the front of the dissecting table: "When the human body passes an electric current of 0.0006 amps, there is a tingling sensation. When the human body passes an electric current of 0.02 amps, it can cause severe pain and dyspnea, in which dyspnea is commensurate with the symptoms of asphyxia produced by the deceased. When the human body passes through an electric current of more than 0.1 amps, it can cause heart palsy, causing the deceased's atria to stop beating until death. ”

"Is it possible that the deceased was artificially electrocuted during the bathing process, and after the electrocution, he slipped into the bathtub, but the real cause of death of the deceased was not drowning, but due to cardiac paralysis caused by electric current. After confirming the death of the deceased, the suspect faked the scene. Li Fei said: "At the time of the incident, there were people other than the Zhu family at the scene. ”

"It's possible, it's entirely possible!" The forensic doctor's eyes lit up: "In previous homicides, the deceased was a single death, such as poisoning, excessive blood loss, suffocation, drowning, etc., but this case is comprehensive and caused by a variety of reasons, so that we are trapped everywhere in the early investigation and autopsy." Once the mind is opened, the case is easy to investigate. ”

As he spoke, the forensic doctor picked up his tools: "You are busy, I will focus on examining the heart of the deceased." ”
