The mobile phone was soaked in the sewage of the river for a long time, and the technical team did its best to only recover most of the memo data, but unfortunately, no chat messages were recovered, which reminded Li Yi of what Team Liu said, but it was rare.

Li Yi and Qin Gang looked at each other intently, word by word, and one of the records attracted his attention:

Mom: 9.23

Dad: 11.25

Lamb: 4.26

This should be a record of birthday information.

Lamb? Li Yi looked up at the sun outside the window that was gradually beginning to sink in the west.

"I think Xiao Yang should be that ghostly Ye Mengyin's boyfriend."

Li Yi didn't answer, obviously, he also thought that it was almost two weeks since Ye Mengyin was killed, this person hadn't even bubbled, and people who like to hide in the dark night and hide in the shadows may not necessarily be a bad person, but they must be someone with a problem.

Thankfully, it was just a simple birthday message, but it finally brought the ghost to the surface. This person close to Ye Mengyin was silent during the period of her death, maybe he was the real murderer.

"I'm sure the problem now is, how do we paint a portrait of him?" Li Yi said.

"Is it the surname Yang or the sheep? Or the homonym of sheep. ”

"The memo says sheep, but it doesn't mean that his surname is sheep. This surname is easy to check, there are about 200,000 people in the country, if the target is placed in the range of 25-35, according to the birth rate of these years, the proportion of population and the proportion of men and women, the number is really small, about 35,000 people, it can be screened according to the household registration information, but put these 35,000 heads on the heads of the two of us, this amount is not small, but it can be expected. ”

"What if the surname is Yang?" Qin Gang continued to ask.

"That would be very tragic, the surname Yang is about 45 million, according to the proportion of the surname of the population and the proportion of the age group, there must be about 11 million, according to the ratio of men to women 1.06:1, 25-35 The male root is 5.66 million, this is the workload of our two lives, if we live long, we should see the dawn of the next new century."

"What if it's surnamed Yang?"

Li Yi quickly typed the word Yang in the search engine, "The surname Yang is about 500,000, to put it simply, multiply the surname of the sheep just now by 2.5, 87,500, this number is also within our reach." ”

"Isn't that a 4.26 birthday, that's a pretty precise range." Qin Gang said.

"You got to the point, according to the daily population of the country, there are about 3 people with the surname Yang born on this day, about 7 and a half people with the surname Yang, and only 669 people with the surname Yang, spanning ten years, and the total number of people is not more than 7,000, so I feel hope."

"That's an acceptable amount."

However, Li Yi prefers that Xiaoyang is a nickname between young couples, not a surname.

The clues must be in it, and his mind is like a CPU, constantly calculating, stacking, and constantly swallowing.

"Then do we need to apply to Team Liu to check the household registration information?" Qin Gang asked.

"It's better not to be in a hurry, this kind of accurate query, according to the national population data volume to do computer retrieval, the result is out in seconds, so whether they visit or not. There are the city, the province, and the province, and the geographical scope may involve the entire land area of our country, but the scope is still too large, and the matter will be multiplied without success. There is another point that we have not taken into account, love is coming, no one can stop it, maybe Ye Mengyin is a sister and brother love, maybe this invisible boyfriend, who is 40 years old or older, is possible. Then we are going in the wrong direction. ”

Li Yi asked Qin Gang to continue to flip down the memo information, there are records of work reminders, there are records of meeting reminders, and there are ...... records of remittance reminders, except for birthday records, other information is completely unhelpful and instructive, no wonder Team Liu said it so vaguely.

"Hey, can't the technical team give some more effort, I hope that we can always encounter this kind of thing."

Qin Gang no longer had the demeanor that he had just said about brainstorming, and his disappointment overflowed.

4.26 is undoubtedly a birthday, but who is he, Li Yi checked all the male identity information related to Ye Mengyin that he had received in the past few days, and did not find it.

However, this piece of information is helpful to Qi Guobin, he is not within the scope of this information that needs to be locked, there is neither time to clean up the scene, nor any motive for committing the crime, nor is he a lamb, let alone traces of the scene, he can indeed rule it out.

Li Yi and Qin Gang conducted a surprise attack on Qi Guobin, focusing on Xiao Yang and Zhuo Yiming.

Qi Guobin made it clear that he didn't know Zhuo Yiming, let alone heard of Xiao Yang, nor did he hear Ye Mengyin and Feng Hui say it, and his every answer no longer had the previous hesitation and panic, but his expression gave people a feeling of discouragement, obviously, his whole person looked very haggard.

Li Yi took Qi Guobin and walked until he reached the gate of the police station, the viciousness of the sun had faded slightly, the air was still stuffy, his eyes were astringent and his throat was dry at this time, what made him a little disappointed was that he had found nothing at present, and his mood was heavy and his steps were heavy.

Of course, Li Yi didn't want to say goodbye, but just wanted to knock it one last time, and when he spoke, his expression was serious and serious.

"Look at you, I've been in twice before and after, and I've made it very clear what I should have said, whether you still have reservations about what you should say, I don't know, I really hope not. There are a lot of ifs, you don't grasp it, if you call the police at the scene of the crime as soon as possible, even if you are suspicious, but as long as you are open in your heart and believe in the police's ability to handle the case, the police can arrive at the scene as soon as Ye Mengyin is killed, perhaps, she has been wronged today. If you call the police as soon as possible, maybe Li Yajing still has a chance to survive, she died of excessive blood loss, I can tell you this. ”

Qi Guobin's body trembled, and he didn't know whether he regretted it or was scared.

Li Yi continued, "If you don't take away your phone, the police can find a lot of clues from your phone and track down the murderer in the fastest time." If you don't throw your phone into the stinky river and soak it, the clues on the phone will not be incomplete, and we can also get more evidence from the phone. If you confess about your phone the first time, we won't waste useless time and energy, and the efficiency of chasing the murderer can be improved even more. Think about it for yourself, because you keep making mistakes, and you have always had the slightest concern in your heart, you will die a miserable death. ”

Two lines of tears flowed from the corners of Qi Guobin's eyes, and he didn't hide it.

"We won't tell Feng Hui about the skirt, it has nothing to do with her, whether you tell her yourself or not depends on your thoughts, and it has nothing to do with us. The matter of the relationship between you, you should handle it carefully and well, people should not have too many distractions and desires, I hope you will appear in the Public Security Bureau for the last time. ”

"I've said it all, and I've hidden it all." The senior's face was full of apology and remorse.

"Okay, when I went back, I suddenly remembered something, so contact me as soon as possible." Li Yi waved his hand, signaling that he could leave.

Qin Gang opened his mouth wide, "Convincing, sure enough, the old ginger is spicy enough to hit the heart,"

Either way, birthday information is a glimmer of light in the dark night.
