Hong Jianying was temporarily detained, and he was still under certain suspicion until his alibi was verified.

Then, Han Bin arranged a task to verify Hong Jianying's alibi, and at the same time found Song Jingshan.

came with Song Jingshan, as well as his daughter Song Boxia.

Although the father and daughter came together, Han Bin did not ask questions together, but asked people to take Song Boxia to the technical team to test fingerprints.

"Officer Han, is there a clue to the person who wrote the threatening letter?"

Han Bin replied, "Do you know Hong Jianying?"

Song Jingshan frowned slightly, revealing a look of reminiscence, "I don't have any impression, what does this person have to do with the case?"

Han Bin took out his mobile phone and found a photo of Hong Jianying, "That's this person." ”

Song Jingshan took a closer look and shook his head, "It's a little familiar, but it's not famous." ”

"This afternoon, he voluntarily turned himself in to the police station and admitted that he wrote the first threatening letter, and we verified his fingerprints to match the fingerprints on the first threatening letter, so we can confirm that the first threatening letter was indeed written by him. ”

"Why did he do this, why did he hurt my son. Song Jingshan looked very excited.

He only admitted that he wrote the first threatening letter, but did not admit that he wrote the second threatening letter, let alone that it was related to Song Bochen's death. ”

Song Jingshan clenched his fists tightly, "Why did he write me a threatening letter...... You've seen that threatening letter, and you're going to ruin my family. ”

Han Bin described the reason for Hong Jianying's crime.

Song Jingshan's voice trembled, with a little self-reproach, "Arrears of wages, just because I owe him a few months' wages, he will kill my son......! I ......"

Han Bin said, "Now it can only be proved that the first threatening letter was written by him, and it cannot be proved that he is the murderer of your son." And he claimed that he had an alibi, which the police are verifying. ”

"Who else is there besides? I can't think of anyone who will kill my son?"

Han Bin touched his nose, "I asked you before, who did you show when you received the first threatening letter, you said that there were only Song Bohui and Song Boxia, let me confirm one side, is it only these two people?"

If Hong Jianying told the truth, he only wrote the first threatening letter, and the second threatening letter had nothing to do with him, and the two threatening letters were almost identical, which was enough to show that the person who wrote the second threatening letter had seen the first threatening letter.

Song Jingshan thought for a while, "In addition to Bo Hui and Bo Xia, Bo Chen was also present at the time, but he was already ...... I didn't mention it. Except for the three of them, only the comrades at the police station knew. ”

Han Bin took the opportunity to think that if Song Bochen was also there, then Zhang Li should also know about it.

Not long after, Song Boxia also returned to the office, Song Boxia was the second, younger than Song Bohui and older than Song Bochen.

Although her name is a bit old-fashioned, she is dressed quite fashionably.

Song Boxia's fingerprint comparison was successful, and the fourth fingerprint on the first threatening letter was indeed left by her.

The second threatening letter is the same as the first threatening letter, which means that the person who wrote the second threatening letter is likely to have read the first threatening letter, or at least know the content of the first threatening letter, otherwise it would not have been able to forge it.

In other words, Song Boxia and Song Bohui also have certain suspicions.

Song Boxia is a woman and not a clown who committed the crime directly, what Han Bin has to do now is to rule out the possibility of her delivering a second threatening letter.

"Miss Song, have you seen the first threatening letter?"

"Yes. ”

"Do you remember the contents of the threatening letter?"

Song Boxia thought for a while, "I remember the general meaning, it was to threaten my father and want to seek revenge on my father, but it has been three or four months...... I can't remember the specifics. ”

"Have you ever told anyone else about this?"

"Nope. ”

"Do you live by yourself, or with Mr. Song Jingshan?"

"I'm living outside by myself, what's wrong?"

"It's just a routine inquiry. Han Bin said perfunctorily and continued, "Between September 6th and September 11th, have you ever been to the Rongding Garden Community?"

Song Boxia recalled for a moment, "Yes. ”

"When did you return to the Landing Garden Community?"

Song Boxia's face changed slightly, "What do you mean by asking, I won't sin when I go back to my own house." ”

"Of course, I said, it's just a routine inquiry. ”

Song Boxia was a little dissatisfied, "But your way of asking me makes me feel very uncomfortable, as if I am a prisoner, and now it is my brother who is dead, you will never suspect that I am a murderer, right?"

"On the contrary, we want to prove your innocence. Han Bin said.

"Huh. Song Boxia sneered, "Prove my innocence? What is wrong with me, why do you doubt me." ”

Han Bin explained, "The suspect who wrote the first threatening letter has already turned himself in, but he does not admit that he wrote the second threatening letter, let alone has anything to do with Song Bochen's death." If what he says is true, then the person who wrote the second threatening letter is likely to have seen the first threatening letter and wanted to blame him in this way. ”

Song Boxia argued, "Comrade policeman, this suspect has already written a threatening letter, he may write a second one, would you rather believe the words of a bad person than believe us?"

"The police only believe in the evidence, we will not let go of any clues, no matter what the relationship between you and the deceased, as long as you are involved in the case, we will investigate, this is our duty, and we are also responsible for the deceased. ”

Song Boxia twisted her head to the side and stopped talking.

Song Jingshan pulled his daughter's arm, "Xiaoxia, what does Captain Han ask you, you just answer." What kind of axis did you commit at this time, Captain Han investigated the case seriously and did not let go of any clues, we should thank him for it, don't you also hope to find the murderer who killed Bochen as soon as possible. ”

"Whew......" Song Boxia let out a sigh of relief and hesitated for a moment, "On September 8th, I went home in the afternoon, went to my bedroom to get some things and left." ”

Han Bin confirmed, "Just this once?"

"Yes. ”

"How long?"

Song Boxia pursed her lips, "I didn't look at my watch, but it wasn't long, less than half an hour." ”

"What did you take?"

Song Boxia flattened her mouth, "I took a few clothes." ”

Han Bin's words changed, "Have you been to the playground recently?"

Song Boxia simply said, "No." ”

Han Bin nodded, "I'm done asking, thank you for your cooperation." ”

Song Boxia shook her head, "It's better than anything else to find the murderer of my brother, I wasn't in a good mood just now, please forgive me." ”

Han Bin nodded in understanding.

Then, Han Bin looked at Song Jingshan, "Mr. Song, Song Bohui has also read the first threatening letter, and we want to ask him to make a record." ”

Song Jingshan sighed, "Captain Han, my son is not in Qindao now, he has gone to other places." ”

Han Bin was a little surprised, "His younger brother was killed, such a big thing happened, and he, the elder brother, went to the field?"

Song Jingshan shook his head and said helplessly, "I can't help it, my lover...... The situation was not good, and he was transferred to a hospital in the capital for treatment. ”

"What's wrong with your lover?"

"Excessive grief has triggered cardiovascular and cerebrovascular diseases...... Let her go to the capital for treatment, first, the medical conditions over there are better. Another one, I want her to change the environment. Song Jingshan sighed, "My wife's favorite thing is this little son...... Bo Chen's death hit her very hard, very hard. ”

Han Bin retreated and said, "Then you tell Song Bohui that the affairs of the capital are arranged, and ask him to come to the police station to make a record." ”

Song Boxia replied, "No problem, I have already bought a ticket to the capital tonight, and when I get there, my eldest brother will be able to come back." ”

Han Bin asked a few more words, but without asking for more clues, he let the two leave.

After Song Jingshan's father and daughter left, Han Bin fell into thought, only the three brothers and sisters of the Song family had read the threatening letter, so if the second threatening letter was really faked, it was likely to come from these three people.

Among them, Song Bochen is dead, and this suspicion can be ruled out for the time being.

However, apart from these three people, it does not mean that no one else is not suspicious.

For example, it is likely that the three men told someone close to them about the threatening letter.

And Zhang Li is undoubtedly the person who meets this condition the most!

"Tian Li, summon Zhang Li to come to the police station to make a record. ”

"Yes. ”

As soon as Han Bin finished giving the order, the door of the office was pushed open, and Zeng Ping strode in, "Team Han, we have found traces of the suspect deck car!"
