"Why did he just dispose of his wallet now, why did he go earlier?" Li Yi asked Qin Gang.

Qin Gang buried his head in his mobile phone and replied to the message for a while before raising his head.

"I sent Zhuo Yiming's photo to Feng Hui, she didn't know her, and she hadn't heard Ye Mengyin talk about any lambs."

"Oh, I heard what you just said, there are two possibilities, one is that there is no way to transfer the money in the card, and the transfer will definitely not work, which will leave traces, and you can only find a way to withdraw it. To go to the bank to withdraw large amounts of money, you need to make an appointment, and you also need the ID card of yourself and your agent, which is a self-imposed net. The same is true for ATM withdrawals, the amount is small and you can't withdraw much money at a time, again and again, the risk is also high, and today's goods are a catch, so you can only give up. The second is that he cares about this wallet, think about it, the password on the paper sleeve was left by this person, the relationship between him and Ye Mengyin is definitely not ordinary, this wallet is meaningful to him, maybe the wallet is what he gave to Ye Mengyin, so the money is not the target, but suddenly he felt that it was not good, so he disposed of it. ”

"The analysis makes sense, but you have to be careful." Li Yi said.

"Notice what?" Qin Gang was confused.

"Don't communicate with people involved in the case at night, and if necessary, visit with your partner, especially the relevant female people involved. The text of our country is broad and profound, and it is easy to make people think about it with the scene, you know what I mean. ”

"Understood, be cautious in what you say and do."

Qin Gang nodded, thoughtful.

“078264，078264，078264。”

Qin Gang repeatedly muttered the withdrawal password of the bank card in his mouth, and stood up from his chair, "Guess what I thought." ”

"Comrade, sit down and speak."

"It's a birthday, 078 is August 7th, Ye Mengyin's birthday, 264 is April 26th, another birthday, the little sheep in the mobile phone memo, 4.26, just right, set the password of the bank card like this, they must be lovers." Qin Gang looked very excited.

"That's right, there are years in the computer. Month. Date format of day, there are also date formats like day/month/year, and the person should have some computer knowledge. ”

Li Yi nodded, "I'll just say that going here is more inspirational than being in the office." ”

Qi Guobin's guess is right, Ye Mengyin has a close relationship with her, to be exact, she is in love. But this person never appeared, as if it had never existed. This seems to be the starting point, and unlike in the past, the person's birthday is now known.

"Let's start with the birthday and look for it from the household registration system?" Qin Gang said.

Li Yi smiled, "You are not good at math, the population born every day in the country is not less than 30,000, Ye Mengyin is 25 years old, let's assume that this person is also between 25-35, such an age difference is appropriate, this is 300,000 people, which is also a comparative amount of the sea." ”

"Ye Mengyin is a girl, that one is a man."

"You can't be sure if it's male or female based on birthdays, and statistics show that the current proportion of homosexuals is about 5%, half male and half female, and we assume that they are just lovers, but we don't identify them as male and female lovers."

"So where to start, the role of this message can't be extended, and it's not of much positive significance." Qin Gang was a little disappointed.

After a few seconds of silence, Li Yi spoke.

"The wallet may have been thrown last night, and Zhuo Yi will cross the road from that place tomorrow, not sooner. The best way to do this is to slow down a little while driving past and throw it away, which can be very smooth without pauses, but the location of the wallet may not be captured by the camera, but I'm sure it's not for money. ”

"Are you sure?" Qin Gang said.

"In addition to bank cards, there are also ID cards, bus cards, business cards, etc., in fact, there seem to be a lot of them. Since the wallet was taken away at the scene, it must not be found by the police. This person knows the password of the bank card and Ye Mengyin's ID card, so he should have time to deal with the money in the card before we receive the police. But what is the intention of this kind of confusion at present, which is the opposite, never touching a penny, and throwing the wallet in a place that is relatively easy for people to see? ”

"This person is worried that the police will not be able to find the wallet and will be in a hurry." Qin Gang joked.

"Well, I'm worried that the police won't be able to withdraw the money and then attach the password, right?"

Qin Gang patted his head, then stood up again.

"I still have a brain hole."

"Well, I've pricked up my ears." Li Yi said.

"We are sure that this person is not for money, and we have also determined that this person is in a relationship with Ye Mengyin, and now Ye Mengyin is dead, but the money belongs to Ye Mengyin. He felt that this was Ye Mengyin's relic and should be given to her family. He can neither express these cards to Ye Mengyin's parents, nor can he hand them over to them personally, now this method is a good trick, borrow our hands to return the card to Ye Mengyin's parents, and the loss of money on the card will not be large, as long as the police act fast enough, maybe there will be no loss at all. ”

Qin Gang's brain hole is really very big, but it is not unreasonable.

"Then he can leave his wallet on the spot, there is no need to take it with him."

"If our reasoning is true, this person entered after Qi Guobin, I believe he spent time looking for the phone, because he had been taken away by Qi Guobin, and he couldn't find it, out of safety, he had to take away his wallet, maybe he finally thought of a way to deal with it in the past two days, and finally threw his wallet into the green belt."

Li Yi suddenly found that Qin had just begun to grow, and bold thinking was a necessary quality for a criminal investigator, before closing the case, there was no absolute right or wrong in all the directions of thinking, and the whole process was often crossing the river by feeling the stones.

"It's very logical, there are multiple personalities, but it's too complex to analyze and write this book, we presume that 1503 is a love murder case, first set this tone, and then find a breakthrough direction. Mobile phone information and wallets can only provide us with analysis, what we need now is how to start taking the next step. ”

The atmosphere returned to silence, Qin Gang turned on his phone, selected a song in the music player, clicked on it and played it in an infinite loop.

"The story can be reversed, and the case can be reversed." Li Yi broke the silence.

"New ideas?"

"We are doing investigations, and we have already checked the people directly related to Ye Mengyin at least twice, and the current harvest is that she is sure that she has a boyfriend, and there seems to be no direction on the road here. But it can be the other way around, to commit murder and deal with the scene, he must enter the scene, with Qi Guobin as the intermediate point, the murderer may not have to avoid the whereabouts of the route too much, anyway, there will be no traces at the scene, and he will not have time. But the person who deals with the scene should enter the scene relatively secretly, because he needs to take a lot of items with him, how does he choose to enter, and then how does he leave? Let's set the tone in that direction. ”

"Vehicles, paths of action, we think about these two points." Qin Gang said.

"We should also go to a place and bring a flashlight, a bag, and a few containers." Li Yi stood up.

"Midnight treasure hunt?"

"Yes, the Beltway."
