"Can you restore the shoe prints of these four people?" asked Xiaotao.

I nodded, "We can restore them when we get back to the station. By the way, send some officers to look along the road. There should be friction marks from the tires at the scene of the collision, as well as fallen teeth and blood from the victim."

Xiaotao got to it at once.

Meanwhile, I raised the victim’s palm to examine it. The victim had slender hands and neat nails which suggested he was engaged in office work. Glancing at his face, I noticed an indentation on his nose bridge left by a prolonged period of wearing glasses.

I checked the victim’s spine and under the eyelids. "The victim is most likely an office worker who spends all his time facing a computer screen. And he usually wears glasses."

"By the way, why is there hair in his pocket?” Xiaotao wondered out loud. “Where do you think it came from?"

"It looks like animal hair. When I sniffed it earlier, it had a damp, unpleasant odor. Cats usually like to stay clean and have soft hair. I think it's dog hair. You can get the lab to test it," I suggested.

At the mention of dogs, I made sure to search the body carefully but found no bite marks.

"Dog? So he may have been held captive for some time," speculated Xiaotao.

I nodded, "Get Bingxin to dissect the body tomorrow and take a look at the stomach contents."

“It's strange for you to take the initiative to ask for an internal autopsy," Xiaotao’s eyes widened in surprise.

I sighed, "The internal bleeding is too serious! The blood may have congealed with the stomach contents and formed a huge lump. I can't get it out so I’ll need Bingxin to do it."

When I stood up again, my vision turned dark for a moment because I had been squatting for too long. Stretching my arms, I instructed, "Transport the body back to the station!"

Xiaotao and I walked over to the cement pipe to look at the other corpse.

Before starting on the autopsy, I opened the Autopsy Umbrella and asked Xiaotao to turn on the ultraviolet light. Unexpectedly, there were messy footprints all around and a pair of clearer footprints on the concrete pipe. It seemed that someone was crouching in that spot earlier.

"Hmph, this bunch of criminals will do anything!” I sneered. “Let’s gather the evidence first!"

Xiaotao called an officer over to photograph the footprints. With the narrow body of the cement pipe, going in would prove rather inconvenient so Xiaotao proposed we moved the body out.

But I shook my head, "No, I’ll go in and examine the body there!"

"How uncomfortable would that be? You can't stand up straight in there," she argued.

"This is probably the scene where this female victim was killed! If the perpetrators wanted to dump the body, why would they have circled around the cement pipe, pacing back and forth? They even stood on top of the pipe which suggests they were here for a long time," I explained.

"Then be careful not to bump your head,” Xiaotao voiced her concern.

I climbed into the cement pipe, avoiding the rough inner walls. When I reached the victim, I was greeted by the sight of open legs and a pool of mixed liquid and blood flowing out from her torn vagina.

Although I had always remained calm in the face of dead bodies, I couldn't fight the anger boiling inside of me upon looking at such a horrible scene.

I didn't immediately begin the autopsy. Instead, I asked Xiaotao to pass me the ultraviolet light. Then, grabbing a piece of cloth made of the same material as the Autopsy Umbrella, I twirled it over the corpse. Immediately, numerous handprints appeared all over the victim’s body, especially on her breasts and hips. They were so densely packed together and overlapping one another that they were almost unrecognizable. Combined with the position of the body, it was obvious that a group of men had taken turns to have sex with the victim.

I put away the light and started the autopsy.

The deceased was about twenty-five years old, with a slim figure. From the pupils and rigor mortis of the body, I narrowed down the time of death to about an hour ago, an hour after the death of the male victim.

There were traces of blunt force trauma and loosening of the hair follicles, as if the victim’s hair had been yanked. Because she was lying naked in the cement pipe, the skin repeatedly rubbed against the walls of the pipe during the violent attack so her back and inner thighs were bloody. Blood had started to congeal on the pipe walls.

Noticing a slight bulge in the victim’s lower abdomen, I asked Xiaotao to bring me a pair of tweezers.

Soon, Xiaotao's voice came from the other end of the pipe. Using a selfie stick, she handed the tweezers over. I might praise her for her ingenuity if I wasn’t faced with such a distressing scene...

I carefully stuffed the tweezers into the victim’s vagina and clipped onto a rather large object. It turned out to be the head of a toy doll with a diameter of about five centimeters.

The doll's head was covered in vaginal secretions, indicating it had been inserted into the victim’s vagina prior to her death. And it was left there for quite some time.

I turned to Xiaotao who was standing at the other end of the pipe, "Reach out and grab the victim's hair,” I said. “You don’t have to pull hard, just make it look convincing!"

As Xiaotao tugged the victim’s hair from the other end of the pipe, I asked, "Are there any footprints next to you?"

"Yes,” she nodded. “And you can see it with the naked eye!"

The realization dawned upon me. "The four perpetrators took turns raping the victim. In order to increase the ‘excitement,’ they stuffed a toy doll's head into her vagina. And in the process of raping her, one of the perpetrators’ companions pulled the victim’s hair from the other end so she couldn’t resist."

"Those beastly bastards!" cursed Xiaotao.

Although the wounds inflicted on the victim’s body were shocking, they were by no means fatal. I listened to the internal organs with the Echolocation Rod and found them intact. The victim had no bone fractures either, though the stomach was relatively empty indicating that she had been hungry for some time.

It didn't seem as if the victim died of suffocation. Thus, I checked the hyoid bone and pulled on the victim’s teeth to ascertain if the perpetrators had choked her or covered her nose and mouth.

Then, I went back to examining her nether regions. Judging from the damage of the inner vaginal wall, the perpetrators raped the victim more than four times. There were two symmetrical indentations in the vaginal opening as if it had been expanded by something. The rough movement caused the opening to tear.

I inserted a cotton swab looking for semen residue but I found only a bit of fresh blood. The color of the blood on the cotton swab was different from the blood around the victim’s vaginal opening, which indicated that she was still a virgin before being raped...

There was some vaginal discharge on the cotton swabs but no semen residue. Placing the cotton swab close to my nose, I took a whiff and found water-based lubricants. It seemed the perpetrators were all wearing condoms at the time.

After the autopsy, I climbed out from behind and took a few deep breaths to calm myself.

"Song Yang, has the cause of death been ascertained?" asked Xiaotao.

"Too much sex!" I concluded.

"Too much sex? But I thought that only happened to men!"

"Being raped can indeed lead to death. This sort of thing varies from person to person. Some women have no problem having sex dozens of times a day, but the victim was a virgin. The perpetrators violently expanded her vagina and stuffed a foreign object into it using tools. And then they brutally raped her which led to tearing. Her organ was in a state of excitement for a long time and secreted too much vaginal discharge, far exceeding the threshold of the victim’s body. Combined with the extreme fear and exhaustion of both body and mind, she suddenly died... "

As a woman, Xiaotao couldn't help biting her lip when she heard the cause of death. After a long silence, she declared, "I must catch these scum and shoot them all!"
