The next morning, two police officers were chatting over breakfast in their office.

Officer A said: "It turns out that the captain also has seven emotions and six desires. ”

Officer B said, "What do you say? ”

Officer A mysteriously lowered his voice, "Last night he asked me for an adult website. ”

"Really?" Constable B was pleasantly surprised and asked, "Which type, is it normal?" ”

"Of course it's normal, but why did he ask me, do I look like someone who will go to this kind of website?" Constable A munched on a pancake with a confused expression.

Speaking of Cao Cao Cao arrived, Song Feipeng suddenly appeared next to the two of them, and greeted him energetically, "Yo, what about breakfast?" ”

The two hurriedly greeted each other, thinking that the captain hadn't heard the conversation just now.

Maybe he got up too late, Song Feipeng's breakfast today is instant noodles, he used the hot water in the water dispenser to soak the dough cake softly, then decant the water, then put in the seasoning and stir well, and then put hot water.

He quickly ran to the technical squadron to grab a cup of coffee, and then put the braised eggs, Vienna sausages, cheese slices and seaweed from the convenience store on the noodles, and explained his food experience to the two subordinates who were stunned in a serious manner: "In fact, this instant noodles have different methods of soaking, and the taste is very different. ”

Officer A laughed, "Not everyone is as food-conscious as you. ”

"Being a police officer is very tired, since you can't sleep well, you have to eat well, and people always need to be satisfied in one aspect so that they don't accumulate anxiety."

Police Officer A remembered the conversation between Seinfeld and him on the Internet last night, "Xiao Li, is there such a website!" "Captain, what kind of website?" "Don't pretend to be garlic, haven't you ever done anti-pornography, that kind of astringent website!" ”

He nodded knowingly, "Indeed, everyone has desires, and if they are not satisfied, they will ......."

"Delicious!! It smells so good! Smell it! ”

Officer A's words were interrupted by Seinfeld's loud praise for the food, and he said in his heart, probably the captain didn't want to mention it.

Seinfeld was contented with instant noodles and finished his coffee, when he suddenly looked straight at the wall, and he said to himself, "If that little girl sent the diary, then this matter is very suspicious!" ”

With that, he left.

The two didn't care, they had long been accustomed to Seinfeld's eccentric temperament, and he often spoke for himself.

At the case discussion meeting in the morning, Xiao Chen talked about the latest discovery, "The scene is an office, and dozens of groups of fingerprints have been found, and in view of the murderer's killing method, it is possible to leave no fingerprints at all." When the site was revisited, phosphors were found in many places under the tables, in the crevices of chairs, on the edges of the tables, and on the ground, which was the same type sold at the stalls at the entrance of the school. ”

"It stands to reason that since the phosphor was left by the murderer, there should also be the murderer's footprints and other traces on it." Seinfeld said.

"No, no, nothing, just trace amounts of phosphor." Xiao Chen said in a straight tone.

"That is, nothing left!?"

"Yes!"

There was a low cry among the police officers, such a clean case is really rare, and Song Feipeng said that the killer was likely to have murder experience.

"About the time of death." Xiao Chen continued, "Through the digestion of the stomach contents and the temperature difference between the internal organs, it can now be determined that the time of death was between half past seven and eight o'clock, and the murderer had turned on the air conditioner in the office to a very low level. ”

"But when the reporter found the body the next day, the air conditioner was not on," a police officer said. ”

"Have you set a timer?"

Xiao Chen answered this question, he said: "The murderer touched the remote control of the air conditioner, because phosphor was also found in the gap of the remote control button. ”

"Guys, why do you think the murderer left phosphor?" Seinfeld asked questions to everyone with blazing eyes.

The group discussed privately for a while, and someone said, "It may have been accidentally encountered." "The deceased got the murderer while he was struggling? "Is it a murder signature? ”

Opinions differ, and a police officer speculated: "Could it be that the murderer deliberately wiped it on his hand." ”

Seinfeld nodded and asked encouragingly, "Then why did he deliberately wipe such a conspicuous thing on his hands?" ”

"Hmm...... Is it for marking? ”

"That's right!" Song Feipeng said happily, "I also considered this detail last night, and I think the reasonable answer is this, the murderer deliberately stained his hands with fluorescent powder before killing people, so that after killing people, he can clearly see where he touched so that he can clean up." ”

Song Feipeng poured a vial of phosphor on the table, took out a plastic ruler and rubbed it on his hair a few times, then put the ruler on top of the powder, and it automatically adsorbed.

In the face of everyone's surprised looks, Song Feipeng added: "After receiving the light for a period of time, the phosphor is very easy to see in the dark, and the deceased was reading a magazine at that time, indicating that the room is well lit, so the time of the crime should be in an environment where the sky is completely dark and the fluorescent lights have been turned on indoors." ”

"But I think that's a bit of a stretch!" The policeman who gave the correct answer just now said, "It is completely possible to kill people with a hammer without leaving fingerprints, and you only need to put a cover on your shoes in advance and leave no footprints." ”

Song Feipeng smiled, "We have to be realistic, since this move seems to be a big deal, under what circumstances is it necessary?" Don't just look at the killing, why did the killer kill, did he have to touch something? ”

"Could it be...... TA is looking for something!? ”

"That's right!" Song Feipeng replied heartily and crisply, "The murderer is looking for something, maybe TA didn't even go to Liu Jia, killing her was just an accident!" There is another possibility......"

Song Feipeng looked around at the listening faces below, his eyes flashed, and he talked about his reasoning eloquently, "Killing Liu Jia is the best solution for the murderer, because if there is no one in the office, the office will be locked." When there was only one person left in the office and only a weak woman left, TA sneaked in, killed Liu Jia, and then found that thing, and then locked the door and left! ”

"The meaning of Liu Jia is a key!?" Someone was shocked.

Song Feipeng nodded, "This simple and crude thinking exposes that the murderer is an 'abnormal' person, TA has the ability and courage to kill, but he can't deal with an old-fashioned ball lock, I don't think TA is a teacher or school worker, not even an adult, TA is a student!" Our eyes should be on what was lost at the scene after the murder, including the other teachers' seats, and filing cabinets! ”

That's why he is so obsessed with Du Shanshan's diary, of course, at present, Du Shanshan has alibi evidence, and she does not fit the outline of the murderer in Seinfeld's heart.

Everyone discussed enthusiastically and excitedly, compared with the case discussion of other captains, Song Feipeng is like a famous teacher who directly bets on the questions of the college entrance examination, he can always point out the way to solve the case in a few words.

The reason why the first team is the top soldier in the criminal police, and the crime solving rate is several times behind the other teams, there is no doubt that it is because of the silver spear head of Song Feipeng.

When everyone was energetic, Wang Bing was a little depressed, he investigated Teacher Feng for two days, but through Song Feipeng's careful reasoning, it seemed that Teacher Feng's suspicion was getting thinner and thinner.

Apparently he had an important piece of evidence in his hands.

At this time, Seinfeld motioned for everyone to be quiet and asked, "Let's not discuss these things yet, what other discoveries do you have made?" ”

"I have one!" Wang Bing stood up and said.
