Du Dayong looked at Gan Changzheng and nodded, thanked him for the chrysanthemum tea, and then looked at the door of the brigade again.
Because Xue Tianhang had already been waiting at the forensic center, Du Dayong just hoped that Xue Tianhang would appear as soon as possible.
Du Dayong didn't see Xue Tianhang until Du Dayong drank a cup of tea several times, so Du Dayong quickly called Xue Tianhang.
"Tianhang, why hasn't the autopsy report come out yet?"
"Awaiting the last toxicology test results? Okay! Then I'll wait for you in the team. Please pay attention to safety on the road."
Finally, at ten o'clock, Xue Tianhang brought the autopsy report. It was not a complete report, just a preliminary investigation report.
As for the portraitist of the Provincial Department who only arrived at the Forensic Medical Center of the Municipal Bureau this morning, he will definitely not be able to count on it for a while.
Du Dayong opened the autopsy report and was shocked after reading it for a while.
The male deceased should be around forty years old, and the time of death was around New Year's Day, five months ago.
The female deceased was about 23 years old and died in mid-November last year, seven months ago.
The woman's body had been forcibly frozen, but the man's body had not been forcibly frozen, but there were traces of freezing, which should be caused by the cold weather in January.
Du Dayong quickly thought of the case of corpses hidden in the refrigerator. There is still no clue to this case. Even though there are already five victims, they have still been discovered. I don't know if there are more that have not been discovered.
The woman died of mechanical asphyxia and the man died of hemorrhagic shock. However, the stomach contents of the male deceased contained sleeping pills.
No drug ingredients were detected in the female deceased.
There was a slight depression in the back of the skull of the female deceased, but it was not a fatal injury. After examining the lungs, it was determined that she died of asphyxiation, and there were obvious strangulation marks on the neck to prove it.
The male deceased's fatal injury was caused by blunt force trauma. The depression was severe and located from the top of his head to the center of his neck.
The forensic doctor initially believed that it was a blow injury caused by a flat surface similar to that of an axe.
Because the main artery in the male deceased's neck was severed and the fracture was rough, it was initially determined that the ax was the murder weapon.
According to the test, the male deceased was already brain-dead after the murderer hit him for the first time, but the murderer must have been afraid that the deceased was not dead, so he continued to chop the victim's neck with the ax blade.
As a result, the victim continued to lose blood because the heart continued to beat and the blood pressure remained for a short time after brain death.
If the contusion formed on the brain does not prove that the deceased's brain is dead, then it can be considered that the victim died of hemorrhagic shock.
The depressed part of the female deceased should have been formed by sharp corners such as bricks and iron drills.
After the female victim fell into coma, she was sexually assaulted and then strangled to death by the murderer.
Their faces were destroyed, and the methods used were also different.
The woman was frozen and then hit with a hammer to disfigure her face, while the man’s facial organs and skin were disfigured with a paper knife.
Although some sperm spots were extracted from the dead female body, it took too long to extract the DNA of the murderer.
No other fingerprints or hair were found on the two corpses, and both corpses were also in a curled up state, indicating that they should have been packed in large suitcases after death.
After the body was buried in the soil, it gradually returned to a flat state after decomposition, but the curled-up corpse spots turned into a flat position again. The formation of the corpse spots was different. The forensic doctor then determined that a large suitcase should be used to transfer the body.
The body was transferred.
Du Dayong looked at the autopsy report and it was written neatly, but all he could think about was comparison.
The soil inspection report from the technical team also came out at this time.
The time for burying the corpse can be determined to be from the 23rd to the 24th of January this year, which is the night of the 30th or the first day of the lunar month, maybe two nights in a row.
Du Dayong had to admire the person who buried the corpse. He knew the time really well. Most of his family members were at home at that time, so whoever was still okay came out for a walk at that time.
