After all, where have I seen you

Unexpectedly, Team Zhang would ask himself to speak at the very beginning, Jin Ran swallowed, "In the past two days, I mainly asked some staff members, the deceased..."

Police officer Zhang stretched out his right hand and pressed it, "Time is limited, we don't need those cumbersome procedures, Xiao Jin, you can directly come to the conclusion, who do you think is the most suspicious, and who should be the focus of interrogation."

"Then, what I suspect most is a person who came to this hospital three months ago. This person had a feud with the deceased not long ago. There were two big quarrels, and almost the whole hospital knew about it."

"What is your name?"

"Yang Mumu?"

"Male and female?"

"female."

"Hahahahaha..." Police Officer Zhang laughed, and the others followed him.

Jin Ran was a little confused, looked around, and looked suspiciously at the senior brother he was calling. The senior brother also echoed everyone's laughter at this time, but obviously his heart was towards Jin Ran, and he looked at Jin Ran a little embarrassedly. Know what to say.

"Oh, Xiao Jin, you only investigated this person after two days of investigation? Are there any other suspects?"

"Uh..." He looked at his senior brother, "It's gone, there is only this doubter for the time being."

Team Zhang shook his shoulders and snorted softly, "As for us, at the scene of the crime, in addition to extracting the fingerprints of the deceased and Mr. Cheng's fingerprints of turning off the faucet, we also found the fingerprints of a person? It is said that the deceased generally does not let anyone Someone entered his room."

Officer Zhang paused deliberately, and Jin Ran looked at him expectantly.

"Based on the amino acid concentration of the third fingerprint, we can basically determine that the murderer is a man." After speaking, he lit a cigarette and took a deep drag. "So, Xiao Jin, your suspicion is in the wrong direction. I gave you two days, but you can't name a male suspect. This is equivalent to the work we came up to the mountain, and it's a new start. You stay What's the use of the next two days?"

"Then... is it possible that the fingerprints are not the murderer's. The murderer is so thoughtful that he didn't leave any fingerprints at all?" Before he finished speaking, the senior brother frowned and shook his head vigorously at him.

"Heh! What do you mean, we don't start with the physical evidence first, but with your suspect first? That fingerprint! Not only in the bathroom! On the cabinet, on the cup, even on the bed! There are! And it's a man!" He stared at Jinran through the smoke with vacant eyes, "The family members of the deceased, including her husband, are all in his hometown of Henan. Do you think the owner of this fingerprint has appeared on the bed of the deceased? No matter what you said, that woman named Yang, More suspicious?"

Team Zhang turned to everyone and ordered: "There are only a few men on this mountain who are either patients or nurses. Collect fingerprints for me one by one, and take them back to the bureau for comparison immediately. Here, investigate every man's background and relationship with the deceased in advance. I don't believe that there are just a few men, and they can't be found out one by one?"

Jin Ran asked, "Don't male mental patients need to do fingerprint comparison?"

Officer Zhang made a lazy expression and continued to smoke.

One of the old police officers replied: "First of all, the number of male patients is huge, which is a waste of time. Secondly, the deceased died of poisoning by poisonous substances, and we did not find any items with poisonous substances in the search, which shows that the perpetrator was clear in thinking and possessed passion. It is difficult for a mentally ill patient without freedom to use such a high-IQ and difficult criminal method to kill people."

Jin Ran had nothing to say, but after two days of observation, he felt that the mentally ill patients in this hospital were different from those in ordinary mental hospitals. They had a very high degree of freedom, and most of them didn't look like patients.For example, the male patient who accompanied Yang Mumu.

"Stop talking nonsense, let's act!"

"Then, Team Zhang, let's collect fingerprints first." The senior brother stood up first, winked at Jin Ran, Jin Ran understood, and got off the chair and stood up, and a police officer who was about the same age as the senior brother also followed the two come out.The rest of the old police officers lit lighters at each other, slumped in their chairs, and began to puff.

"Brother, what are the specific results of the autopsy? Didn't you say that no poisonous substances were found in the test? Why did you hear what Team Zhang said just now, and the deceased was poisoned by alcohol again?" Jin Ran who walked out of the meeting room asked immediately.

"The cause of death was indeed poisonous poisoning."

"Aren't there chlorination compounds in toothbrushes and toothpastes?"

"There are no cups and tableware, including toiletries, and all items have no crystals."

"Then, how did the murderer poison him?"

"do not know."

"Brother, have you read Keigo Higashino's "White Night Journey"?"

"Ok?"

"If I remember correctly, the protagonist poured sulfuric acid and potassium cyanide or sodium cyanide into the toilet, and then closed the toilet lid. The deceased opened the toilet lid to inhale the hydrogen cyanide gas generated by sulfuric acid and potassium cyanide, and then..." Jin Ran grabbed his neck, stuck out his tongue, and rolled his eyes.

"But..." said another police officer who came out. "At the scene of the crime, the toilet seat was closed. It's better to obediently collect fingerprints, wait until the murderer is caught, and listen to how he poisoned himself."

"However, I always feel that in this case, the murderer cannot be found through a simple comparison of fingerprints."

"When you work for a few more years, you will understand that solving crimes in reality is not about suspense dramas and detectives, there are not so many high-IQ crimes, and solving cases depends on patience and carefulness."

The three told Director Cheng to call out all the male staff members in the hospital and collect fingerprints one by one.The brother immediately drove down the mountain with these fingerprints.
