After Han Cheng and Yu Shan had a bowl of mutton noodles at a roadside stall in Yinshi, Guo Yue took them to the place where the mother and daughter were killed by the hammer maniac.
The mother and daughter who were killed were named Ning Xiao. She was only 32 years old when she was killed, and Ning Xiao’s daughter was only four years old!
Ning Xiao was an employee of a textile factory back then. The house she lived in was a dormitory assigned by the factory. Although the dormitory building has not been demolished yet, it has been dilapidated and abandoned for many years.
The strong wind blew into the building, making a whining sound, as if an innocent soul was crying.
From a distance, the dormitory building surrounded by weeds looks like a ghost building.
Han Cheng walked into the dilapidated dormitory building and stood at the door, feeling the strong resentment.
The resentment seemed to have vitality. It turned into a strong wind and blew toward Han Cheng.
It was like Han Cheng told her grievances and asked Han Cheng to avenge him.
"That mother and daughter died so tragically! Ning Xiao's head was smashed with a hammer by the murderer. The girl was only four years old, and her head was smashed to pieces... "
Arriving at the door of the house where Ning Xiao's mother and daughter lived, Guo Yue stood by the door and sighed, his eyes full of pain and regret.
"I will never forget this case for the rest of my life. I swore back then that unless this case was solved, I would never give up investigating this case until the day I die!"
Guo Yue's eyes were reddish and his eyes were sad. He seemed to have seen the scene of the mother and daughter dying tragically here again...
"Was anyone in this building when the crime occurred?" Han Cheng asked.
"Yes! But there were only a few scattered families at home, because it was ten o'clock in the morning, which was the working time of the textile factory, and most people had gone to work!"
"Then why did Ning Xiao and her daughter stay at home?" Yu Shan asked.
"Her husband said that his daughter had a fever that day, so Ning Xiao took leave to take care of her daughter at home!"
While Guo Yue was replying, Han Cheng walked into the house where Ning Xiao's mother and daughter lived, followed by Guo Yue and Yu Shan.
"No one has lived in this room since. After the textile factory closed down, everyone left here, and this building became deserted here!" Guo Yue continued.
"What did the murderer take back then?" Han Cheng asked.
"Basically all the valuables in Ning Xiao's home were taken away by the murderer, including 30,000 yuan in cash, watches, jade bracelets... Even the gold necklace Ning Xiao was wearing was taken away by the murderer!"
"Thirty thousand yuan in cash? How can Ning Xiao, who is just an employee of a textile factory, have so much cash?"
"Ning Xiao is an accountant in a textile factory. She took out the 30,000 yuan and planned to take it to the factory to pay wages to some employees the next day!"
After listening to Guo Yue's words, Han Cheng frowned and fell into deep thought.
Could it be that the Hammer Maniac had followed Ning Xiao in advance and knew that she had a large amount of cash hidden at home, so he chose her as the target of the crime?
Han Cheng thinks this is very likely.
Because he has analyzed more than fifty cases committed by the Hammer Maniac and found that the vast majority of the victims are wealthy people with a little money.
Therefore, for a person with such a high IQ, Hammer Madman should not commit crimes casually. Once he commits a crime, he will definitely pick a "fat sheep" to start with.
But on the surface, Ning Xiao does not come from a wealthy family. She is just an accountant in a textile factory, with a low salary and simple dress.
Why did the Hammer Maniac want to target her?
Han Cheng thought that Ning Xiao was targeted by the Hammer Maniac when he went to the bank to withdraw money, which was why he suffered this misfortune.
From this point of view, banks should be places where hammer maniacs often go to find their targets.
Han Cheng thought while observing the whole room.
After years of erosion, this room has long been beyond recognition. The dark areas on the walls are covered with moss, there are spider webs in the corners, the wooden table is covered with dirt and dust, and a musty smell permeates the air.
"Where were the bodies of Ning Xiao and her daughter when you entered the house?" Han Cheng continued to ask.
"Ning Xiao's body is in the kitchen, and her daughter's body is on the bed in the bedroom!" Guo Yue replied.
"Captain Han, what did you find?" Guo Yue couldn't help but ask when he saw Han Cheng frowning in thought.
"I remember the autopsy report said that Ning Xiao was hit on the head from behind with a hammer?"
"Yeah, three holes were hit in the back of the head!"
"And the place where her body is is in the kitchen!"
Guo Yue nodded, "Does this mean anything?"
"From these two points, it can be inferred that the Hammer Maniac should have first attacked Ning Xiao from behind the house!" Han Cheng said.
"Yeah, why didn't I think of that!" Guo Yue suddenly realized.
"Then who would make Ning Xiao let down his guard and let him enter the house?"
"Acquaintance?" Guo Yue blurted out.
Han Cheng nodded, "It's possible!"
"But we investigated Ning Xiao's social relationships back then, and there was no suspicious person among Ning Xiao's acquaintances!"
"In addition to the people Ning Xiao knows, there is another type of person who might make Ning Xiao let down his guard and let him into the house!"
"What kind of people?"
"Uniformed staff, such as police, or reading water meters, etc.!"
"Han Cheng is right. Psychologically speaking, ordinary people like me will have a sense of trust in certain groups of people wearing uniforms and will relax their guard!" Yu Shan said!
"This hammer maniac is too cunning!" Guo Yue said angrily.
"Have you ever checked which bank Ning Xiao withdrawn money from back then?" Han Cheng asked.
"No! At that time, we thought this was a random home invasion and robbery case, so we focused our investigation on the released persons with robbery records in Yin City!"
"I haven't checked the other details in detail, but it's not difficult to know which bank the textile factory drew the money from back then. Ask the accountant of the textile factory back then and they should know!"
Han Cheng nodded, "It's not too late! Let's go find them and ask them now!"
Although Guo Yue was a little confused as to why Han Cheng wanted to know from which bank Ning Xiao had withdrawn the 30,000 yuan in cash, he felt that Han Cheng was a person sent by the Longguo Criminal Police Headquarters, and he must have something special about him. .
How could ordinary people like him guess the thoughts of an expert?
So he immediately agreed: "Okay! There is an accountant who is close to Ning Xiao and lives not far from here. We can ask her!"
