It was after lunch, when everyone was drowsy.
Unexpectedly, the police station suddenly received a strange phone call. The voice on the phone was a strange baby voice, "I want to report Song Xiaofan now. Song Xiaofan is the murderer of the Xilang Mountain murder case."
Experienced responding police officers felt very uncomfortable when they heard the strange baby noise. Although it is a baby voice, the sound of it makes people feel goosebumps all over their bodies.
At noon, the sun was still shining, but the police officer felt like he was in a dark cellar, and his whole body was uncomfortably cold.
So the call was suddenly hung up, and the police officer who answered the call had no time to ask who the caller was. Seeing the call being hung up suddenly, the police officer who answered the call was extremely upset and felt like he wanted to cry without tears.
Of course, he was also surprised.
The police station was offering a reward for Liu Hu's whereabouts. Unexpectedly, the caller turned around and secretly reported that Song Xiaofan was the murderer of the Xilang Mountain murder case.
hey-hey! interesting.
The police officer who received the call immediately told Lao Sun the news, and also mentioned the uncomfortable baby voice.
When Lao Sun heard this, he asked him to describe the baby sound, but how could a grown man like him learn it?
He couldn't laugh or cry, "That person must have used voice-changing technology."
Lao Sun smiled, "Oh."
Zhu Lan asked: "Oh, Master, I understand. The caller definitely doesn't want us to know his identity, so he needs to change his voice."
"anything else?"
"The caller must know us, or we have seen the caller and naturally heard his voice."
Lao Sun nodded, touched her short hair and sighed, "You are getting better and better, and one day you will catch up with Master."
Who is this person who reported Song Xiaofan? Could it be the missing Liu Hu?
"I don't want it, Master, I want to be your disciple forever." Zhu Lan said coquettishly.
Therefore, the task of tracing the owner of the phone card with these 11-digit phone numbers and the voice-changing software he or she used fell on Xiao Feng.
He complained, "Why is it all my fault?"
Everyone laughed, and he didn't say much and went to work immediately.
After working hard all afternoon, Xiao Feng finally found the clues. The owner of the phone was a thirty-three-year-old man named Xu Da. His family lived in Zhuyu Village, Qingcheng City, where the deceased Zhang Zhen lived.
Could it be that Xu Da not only knew Zhang Zhen, but was also very familiar with him?
Lao Sun immediately went to visit the man named Xu Da, who happened to be resting at home. Unexpectedly, he shook his head vigorously and said: "Impossible, I have never made such a call! I don't know Song Xiaofan at all."
What a strange thing. It was clearly Xu Da's phone number that made the call to the police station. Why is he denying it now?
So, she asked again: "So, have you ever lent your phone to others?"
Xu Da wiped the cold sweat from his forehead, thought for a while and suddenly shouted: "By the way, I remembered that there is indeed such a man. I lent him the phone and he said that he had run out of battery. Just borrowed it."
Lao Sun asked: "Who is he? What is his name?"
"He is new here. He is tall, has a good-looking oval face, and is quite handsome. He is about 35 years old." Xu Da recalled.
"What's new?"
"I work at Feida Express Logistics Company in Qingcheng City, and he has only been here for less than three days."
"So is he still there now?"
"Who knows? You can go find it yourself?" Xu Da shouted.
So Lao Sun immediately rushed to the Feida Express Logistics Company to look for him. He hurriedly hurried but was still a step late. The female proprietress dressed in gold and silver said contemptuously: "Humph! He has only been working for less than three days, and he has already been here." Let me pay my salary and leave. Huh! No wonder you are so poor, you are not lazy!"
Lao Sun and Zhu Lan were both shocked.
"We're a step late again."
"I actually let him run away!"
"By the way, have you registered his personal information?"
"We don't need an ID card to work here, because when he came he said he would be a temporary worker, responsible for loading and unloading."
"oh."
So Lao Sun and Zhu Lan returned to the police station.
Now it seems that even tracing the owner of the phone number is useless. Because the caller did not use his real-name certified mobile phone number to report clues. Unable to verify.
Zhu Lan suggested using surveillance to search.
The landlady reluctantly identified a tall figure from behind and said it was the temporary worker who had left. The man always wears a long peaked cap, and the brim of the hat is deliberately pushed down very low.
The surveillance camera never illuminated his face, so it was impossible to identify who he was.
Lao Sun shrugged and said, "What a cunning person."
So they returned to the police station.
Xiao Feng has not yet found out how to use the voice changing technology.
He went to ask the receiving officer.
The police officer who responded said that the baby sound was familiar, but he couldn't tell where he had heard it. You may have heard it in some scene in your life, but never paid attention to it.
Xiao Feng was racking his brain and couldn't think of where he had heard a special baby sound.
Could it be editing software for editing pictures and processing sounds? Many bloggers now use editing software to create short videos. Once accustomed to using their own voices, bloggers often try using baby sounds.
Xiao Feng suddenly thought of this possibility.
He was trembling all over. Now is the era when everyone is watching short videos. He will also watch short videos when he has free time.
Although he is very busy and rarely views short videos, he has actually heard baby sounds in short videos. He even once made a short video, and the editing software is still stored on his phone.
The baby sound can become sharper depending on the speed of the short video playback, and vice versa!
It's very common and the easiest to ignore.
Could it be that the caller used editing software?
During the process of restoring the original voice of the report phone, Lao Sun and Zhu Lan listened together. The voice was indeed very familiar, it was Liu Hu!
It's a pity that damn Liu Hu can't be found.
They went to Ms. Wang's home again, but Ms. Wang also said that there was no sign of Liu Hu coming back recently.
Lao Sun sent his subordinates to search around the city, and at the same time activated the city's sky eye to assist in the search.
She didn't believe that Liu Hu could spread his wings and fly away. Even if he could escape to the end of the world or the corner of the world, she would definitely catch him back.
So where the hell did Liu Hu go? He pretended to be a temporary loader and deliberately borrowed Xu Da's phone number to report this clue. What was his purpose?
Could it be that there was a deep hatred between him and Song Xiaofan? Or did he really see Song Xiaofan attack Zhang Zhen with a golden switchblade?
