The police received the visiting whistleblower very politely, but it was only a professional politeness.

Originally, this kind of suspicion of ordinary people did not attract much attention from the police. This is also a helpless move that has learned from the past.

In the process of solving cases in the past, there have been many times, because ordinary people have provided some so-called clues according to their own suspicions, but the result has misled the police, resulting in the direction of the investigation, wasting manpower and material resources is a trivial matter, and the most important thing is that the time to trace the real clues has been delayed.

Perhaps even if it is delayed for two or three days, it will have very serious consequences for the entire case, and it is very likely that no real physical evidence can be found that can be convicted, thus complicating the case, and even making it impossible to solve the case in the end.

However, in a serious and responsible manner, the police still sent someone to accept the shirt provided by the informant. Unfortunately, the traces department was unable to obtain useful evidence.

Through luminol (also known as luminammonia) reagent testing, the faint pink imprint on the shirt can indeed be confirmed to be bloodstains, but the owner of the shirt should have used detergent, disinfectant, etc. to clean the shirt, and the DNA of the blood sample extracted from the bloodstains has been destroyed and cannot be extracted, so naturally there is no way to compare it with Wu Yueying's DNA, so as to confirm whether the blood stains on the shirt were left by Wu Yueying when she was injured.

Although the traces inspection department was unable to find substantial evidence, after all, the whistleblower provided the only clue about the suspect in the case so far, and the police still summoned the whistleblower's neighbors for questioning in accordance with the procedure.

During the interrogation, the confessions of the two suspects were only submissive and secretive, which made the police really suspicious, so they applied for a search warrant and searched the suspects' homes.

The search finally came to fruition. A set of knives was found in the kitchen of the suspect's home, which was a five-piece set of ordinary kitchen props, but the place where the fruit knife should be inserted was empty.

The knives are very new, and it can be seen that the two of them rarely cook at home. Each knife has a Subbayer logo near the handle, which should be the purchase of Subaer's kitchen utensils, which was given by the merchant. And this logo happens to be consistent with the abandoned fruit knife found by the police near the crime scene that possessed the victim's blood.

The police took the fingerprints of the two suspects, and determined that the fingerprints left on the murder weapon and the victim's robbed handbag matched those of one of the two suspects.

"I went to see the two suspects yesterday afternoon. Hu Hao said unhurriedly.

"And then?"

"One of them, 'A' for short, is nothing special. According to him, he followed 'B' for a walk, and when he arrived at the office building where Wu Yueying was, he happened to meet Wu Yueying going out with a small bag, and he didn't know why 'B' suddenly froze, and said to himself that he was going to snatch her bag, and then rushed up. 'A' didn't think much about it at the time, and hurriedly chased after him, originally planning to apologize to Wu Yueying that he was joking, and then dragged 'B' away, but who knew that 'B' suddenly took advantage of Wu Yueying's turn to look at 'A' and suddenly took out a fruit knife and stabbed Wu Yueying. Seeing the victim fall to the ground, 'A' also panicked, and quickly dragged 'B' and ran away. ”

"What about 'B'?

His confession was a bit strange. Hu Hao frowned, "According to 'B' himself, he doesn't remember that he ever robbed and hurt people. All he remembers was that he was shopping with 'A', and then it was already blank, and by the time he had a memory, he was already surfing the Internet. ”

"Could it be that he deliberately concealed it and wanted to escape the law?"

"I can't be sure, but there is witness 'A', and there is physical evidence of a handbag and a murder weapon, so it stands to reason that even if he is not familiar with the law, he can know that he will definitely be convicted, and the confession is no longer the most important thing. In this case, there is no need for him to deliberately conceal it. ”

Hu Hao paused, looked at Wang Yiyuan, and said, "The process of catching the suspect in these two cases is very coincidental, have you found anything similar?"

Wang Yiyuan's eyes widened: "What do you want to say? I want to say that the suspects in the two cases were caught on the day I left Baqing, right? I want to say that I am a moldy person, and it will affect the course of the case here, right?"

"Poof, you're thinking too much, what do I mean!" Hu Hao laughed, "But you have a point, this is another place." And what else?"

Wang Yiyuan realized that she seemed to be being played, but the words were said by herself, and it was always difficult to be angry with others, so she had to endure it.

"And? well, I think about it. By the way, the suspects in both cases said that there was a gap in their memory!"

"That's right!" Hu Hao nodded approvingly, and then frowned again, "But this is too strange, plus you were hit by a car before, this is the third case in which the suspect claimed to have lost his memory." But I have roughly investigated, except for you and Wu Yueying, the three victims and the suspects in the three cases have almost no intersection and no other things in common, why is this happening?"

Mass amnesia? It's unlikely.

There are three main types of amnesia, which, in addition to the relatively rare dissociative disorder, also include the onset of the disease due to organ or functional causes.

The suspects in the three cases had normal brain function, obviously not an organ cause, and according to the fact that they only lost part of their memories at a specific time, they should belong to psychogenic amnesia (also called functional amnesia), but several unrelated people all became ill at the time of the crime, is this possible?
