Fang Lubai here was pondering about the watch, and Shi An over there had already finished his investigation of a certain mother and walked over here.

She walked up to Fang Lubai, the smile in front of her had a complicated expression, her eyes were red, and she looked sad because of the sudden death of her best friend, she had some sympathy in her heart, and turned her head to look at Fang Lubai.

Fang Lubai's attention was obviously not here at this time, his eyes were a little distracted, staring at the watch in his hand without saying a word, he was usually keen, and he didn't notice that Shi An had walked to his side, he just looked at the watch with a deep look.

Shi An tugged at his sleeve, trying to bring him back to his senses: "Fang team, Fang team, are you okay?"

Shi An's voice suddenly pulled back Fang Lubai's thoughts, he raised his head to meet Shi An's slightly worried eyes, and waved his hand at her to signal that he was fine.

But Shi An was still a little uneasy, feeling that Fang Lubai was too nervous because of this case, so he was not in a good state now, so he turned around and went to the water dispenser in the living room to get a disposable paper cup, took a cup of warm water and carefully took it to Fang Lubai.

"Drink some water, don't be so nervous." Although Shi An has a reckless personality, she is a girl after all, and the tenderness in the girl's bones is shown at this moment.

Fang Lubai glanced at her, took the water cup from her hand and said thank you, and brought the cup to his mouth and drank it all under Shi An's gaze.

Putting the paper cup on the table next to him, Fang Lubai raised his head and looked at Shi An: "How is the investigation on Yu's mother's side?" ”

Shi An shook his head: "There are no clues, she said that Yu has always been kind and has a good temper, and I haven't heard her say that she has any disputes with anyone." ”

"Where's the red bag?"

"The red bag was bought by herself, Yu Mou's social background is relatively simple, I just listened to other people's investigations, and I didn't seem to find any contradictions between her and people."

"Is that ......" Fang Lubai subconsciously reached out and touched his chin, which was his habit when he was confused.

"Square team...... Don't push yourself too hard, the case is important, and you have to take care of your body. Shi An glanced at Fang Lubai, who was haggard, and didn't know that he went to the scene of the corpse dumping scene last night to simulate the case, nor did he know that he picked up a watch, let alone that this watch could shout that Fang Lubai saw the picture six hours ago, she just thought that Fang Lubai couldn't sleep well all night because of the case.

"Okay." Fang Lubai only responded, and did not plan to tell Shi An about the watch, this watch was too magical, and he still needed to study how to use it, and even if he said it, Shi An would not necessarily believe it.

Team A was done within an hour of the inspection, and most of the members were sad, and it was clear that the results of the investigation were not satisfactory, and most of them were the same as the first one, with no major changes.

Several people got into Fang Lubai's car, preparing to return to the criminal police team together, Shi An, who was sitting in the co-pilot, asked Fang Lubai while wearing a seat belt: "Fang team, how do you know that Yu's mother was wearing white clothes this morning, have you seen her?" ”

Fang Lubai inserted the key for a moment: "Well, I happened to pass by this morning." ”

"That's right." Shi An didn't doubt what Fang Lubai said at all, and nodded to himself, "There are no clues on Yu's side, so I can only look at the other groups next." ”

Fang Lubai bowed slightly, and then drove to the criminal police team.

But it should be the same as the results of the last survey. He thought.

In the conference room of the criminal police team, he sorted out the information provided by the results of this investigation again, and the results were not what he expected, and there was no useful information at all, and what the subject of the investigation said was basically the same as what was investigated last time, and there was not much difference.

The three deceased are very popular, except for the second deceased and his ex-boyfriend, there is nothing else, but the second deceased's ex-boyfriend has already gone to Japan on the day of the breakup, and after the investigation, he worked in Japan a few days after the crime, and he did not have the time to commit the crime and was not present.

After the others reported their investigations one after another, Shi An sat next to Fang Lubai, looking at his frowning appearance, he knew that the results of this investigation still had little effect.

She suddenly had an idea: "Fang team, could it be that the murderer actually has nothing to do with the deceased?" ”

Fang Lubai raised his head and looked at her: "What do you mean?" ”

"The murderer, could it be that he passed by a certain place, or met someone, the three deceased all had the same red backpack, and the murderer killed them, could it be because of the red leather bag?"

Because of the red leather bag?

Fang Lubai's eyes flashed, and he moved closer to Shi An: "You go on."

Shi An nodded: "You see, the three deceased have no other common characteristics except for the red leather bag, I don't think it's correct to start with the social background and character relationship of the deceased, so we can't find key clues, but we can't say that the murderer didn't win the lottery today, or was beaten up in a bad mood so he killed someone, right?"

The atmosphere in the conference room was a little tense, but as soon as Shi An's words were driven, he suddenly relaxed a lot, some people lowered their heads and laughed softly, even Fang Lubai was a little helpless to Shi An, he raised his hand at Shi An, and motioned for her to continue.

Shi An bent the corners of his mouth and continued: "So I think the red leather bag is the real key."

"So you think we should start with the red purse?"

"Yes."

But the task is too difficult.

Investigate this red leather bag, that is to say, investigate the entire market of this red leather bag and all consumers, and then investigate step by step, filter everyone who is not suspected, and finally launch the murderer.

But it's no different from looking for a needle in a haystack.

Not only because of the heavy workload, but also because of the difficulty of such work, even if other people can be filtered out of it, whether the murderer can be found is a big problem, even if it takes a lot of time to interrogate and investigate, if the murderer still commits the crime during the period, the security of the entire S city will become chaotic.

Fang Lubai hesitated a little, but at present, this is the only direction to detect, but if this is the case, it will take a long time not to say, and it will also give the murderer a lot of time and opportunities.

"Let's start with the shop where the three deceased bought the red leather bags, and see if there are any other people who have bought the same leather bag during that time."

"Okay."

Although the task was difficult, the criminal police team still obeyed the captain's arrangement, and someone quickly found the shops purchased by the three deceased people, and distributed the information to each member.

Shi An immediately went to the printing room with the USB flash drive, marked some key contents, and then copied the shop information and the time of each deceased's purchase, and then carefully sent it to everyone after printing.

Everyone did not delay, Fang Lubai simply assigned the task and set off to investigate.
