The previous victims were actually in similar situations. In the eyes of others, they were good husbands and virtuous wives, but they had unknown sides behind them. When interviewing their colleagues, relatives, or friends at the time, they were all greatly surprised.
We first took the bloody threatening letter back to the technical investigation department for processing. Then, Liu Yuning and I went to Teng Yanrou's home. To understand her whereabouts and some circumstances before her accident, investigating her home was the most practical approach. At the same time, I found the nearby police station to assist. After obtaining road surveillance footage and having Xia Hou monitor the traffic management bureau, Liu Yuning and I arrived at Teng Yanrou's home and searched the drawers and cabinets again, but found nothing this time.
However, in the kitchen, we discovered strange signs. A pot contained a cooked heart!
That's right! A cooked heart! We had been looking for Teng Yanrou's body parts all along, and we never expected to find such a scene in her home. We had actually been here before, but at the time, we didn't investigate in detail, only asking about her husband's situation.
During this re-examination, we made a new discovery. Her husband had not yet discovered the situation here, likely because he hadn't returned since Teng Yanrou's accident. I first put the heart into an evidence bag, then took out yellow wine and sprinkled it around. After a series of basic operations, we found blue-green reactions all over the kitchen cabinet.
Alright, given the amount of blood, if I'm not mistaken, this was very likely the primary crime scene. Teng Yanrou was killed and dismembered here, and then the killer transferred her head.
We didn't find other body parts in Teng Yanrou's home, only that heart. Of course, before comparison, this heart might not be hers. I pondered, and following the bloodstain reactions, I entered the bedroom. Using yellow wine again, I found strong reactions on the bed. Teng Yanrou was likely tortured on the bed. Considering she was tortured for some time before dying, could it be that the killer directly committed the act in her home?
But Ye He hadn't left for long, had he?
I suddenly felt that Ye He might still be problematic. I discussed it with Liu Yuning, and we decided to split up. Liu Yuning would take things back, and I would go find Ye He again.
This time, I found him at his company. When asked about his business trip, Ye He seemed a bit embarrassed. However, I appeared very serious: "Mr. Ye, we've recently discovered the situation at your wife's home, and that she took leave some time ago. This timing completely contradicts your business trip. Tell me honestly, how long have you actually been away?"
"I was out of town for just those few days!"
"Are you sure? If that's the case, the fact that your wife was tortured for a period of time doesn't add up. Do you know the seriousness of withholding information?"
I spoke with a threatening tone, but Ye He still seemed to want to conceal something. I was curious why he didn't want us to know those things. Could he truly be involved in the case?
"I was at home during that time..."
"Haha, if you were at home, does that make you the murderer!" I deliberately probed.
"No, that's not what I meant. Alas, forget it. Actually, our relationship broke down long ago. I haven't been back for almost a month. But don't let my father-in-law know! Otherwise, my job will be..."
"What? Your father-in-law?"
Ye He then said seriously: "The reason I concealed it wasn't because of the case, but due to work. Everything I have in my company today is entirely thanks to Teng Yanrou's father. If he knew we had broken up long ago, he would definitely not help me anymore. Do you understand? That's why I lied!"
But I felt a wave of disappointment. However, subsequent verification confirmed that the situation was indeed as Ye He described. It seemed I had misunderstood.
It wasn't until I returned to the provincial department that the test results for the heart came out. The heart indeed belonged to Teng Yanrou.
However, this result was within my expectations. Fine, now I still had to figure out how to slowly find her body parts. This wouldn't be resolved quickly, as the killer had given us no clues this time.
And so, we continued investigating without knowing where to turn. I went back to the technical investigation department, and they told me that the blood on the letter was not from Teng Yanrou but from Quan Yingzhen. It seemed that when killing Quan Yingzhen, the killer had already prepared to deal with Teng Yanrou.
He was definitely meticulous. Targeting these enemies from the past who had taken something from him, he was enacting revenge. Therefore, the case was classified as a revenge killing, not a crime of a perverted killer.
In fact, I had long had this premonition, and with the details of the case from multiple angles showing this pattern, even a newly arrived police officer would think so.
That day, Ma Biao suddenly found me. I thought he had some questions to consult. However, he said excitedly: "I think I've found some clues to the killer's movements!"
"Huh? Are you joking?" If Liu Yuning or someone else had told me this, I would have believed them, but Ma Biao...
"I'm serious. Didn't I study the dumping grounds of the victims on the map again? Do you know what I discovered?"
I shook my head, genuinely curious to hear what he had to say next.
He spoke unhurriedly and meaningfully: "These points form a huge ellipse. The killer seems to be going in circles, not trying to disrupt the sequence or confuse us. Instead, he has provided us with the exact location of Teng Yanrou's dumping ground. Look here, and here, doesn't it all lead back to a single point? It's like the game of Snake we play!"
If Ma Biao hadn't unexpectedly said this to me, I wouldn't have realized that these intersection points indeed had such a pattern.
But at that moment, I found He Xin, and the few of us compared them again carefully. As soon as I understood, I slapped my thigh and told Ma Biao and Xia Hou to follow me immediately.
At that time, Liu Yuning and Xiao Yuande also appeared eagerly beside us. When we reached the tail end of the intersection points, the tail of the snake, we found it was a forest park. Although Teng Yanrou's body parts might be here, finding them in such a large park would be extremely difficult.
What should we do? I looked at Ma Biao. He looked deep in thought. If the body parts were in the forest park, it would be somewhat manageable; otherwise, it would be even more troublesome. Without a specific location, we had to find the park security guard and ask him some questions.
I said, "Have you seen any strange people entering or leaving the park recently?"
