"Han Cheng is right. People like the Hammer Maniac who are used to living alone and are very suspicious will not be left alive!" Yu Shan said.
Han Cheng nodded, "If Cao Jing's driver is the traitor, this can also explain why he died at the end and why he was attacked on the back of the head by the hammer maniac when he went downstairs..."
"Also, I inspected the wounds on the heads of two security guards in the ice room and found that the murderer of the security guard who died in the security post used a smaller hammer to kill him.
"And the intensity of the murderer's attack was much weaker than the previous attacks by the Hammer Maniac on his victims."
"This means that the person who attacked the security guard at the security post should be Cao Jing's driver!"
"Let me try to reconstruct the events of this case for you!"
"On the night of the incident, Cao Jing's driver secretly put sleeping pills into everyone's meals. Everyone fell asleep deeply after eating the meals containing sleeping pills. At around 1 a.m., he used a hammer to hit the sleeping security guard at the security post. Kill him, and then open the door to let the Hammer Maniac enter the villa."
"Then, he took the Hammer Maniac to the room where other people lived and asked the Hammer Maniac to kill everyone one by one. But he didn't expect that the Hammer Maniac would eventually kill him too when he was not prepared!"
........
"Han Shen, how should we investigate next?" Hong Xi asked.
Han Cheng pondered for a moment, "Now we can only find clues from the dead driver!"
"Since Hammer Crazy and Cao Jing's driver know each other, maybe the driver's friends may have met Hammer Crazy."
"Then let's investigate driver Cao Jing's social connections now!" Hong Xi looked a little excited.
Because this time is the closest they have come to revealing the true face of the Hammer Mania.
After some investigation by Han Cheng and others, they learned that Cao Jing's driver was named Bai Tian. He was 30 years old when he was killed and was unmarried. He had a girlfriend named He Bing whom he had been with for many years.
In the eyes of outsiders, Baitian is an honest and responsible person, and it is precisely because of this that Cao Jing chose him as his driver.
Baitian is an only child, his parents are now deceased.
If you want to know more about Baitian's personal information, it seems that you can only go to his ex-girlfriend He Bing to inquire!
After all, the two had been together for several years, and He Bing should know Baitian better than anyone else.
However, when Han Cheng and the others found He Bing, she was unwilling to mention Bai Tian, saying that she was now a married woman and she did not want to talk about her ex-boyfriend to avoid her husband being angry.
Although Han Cheng and the others were a little disappointed, they couldn't force He Bing.
Seeing that the case was about to make major progress, unexpectedly it got stuck at He Bing's place.
Yu Shan was unwilling to give in, so she went to find He Bing alone.
He was moved by reason and affection towards He Bingxiao, and told her about the heinous cases committed by the hammer maniac.
In the end, He Bing was finally persuaded by Yu Shan, and she was finally willing to accept Han Cheng's inquiry.
Pau police station, interview room.
He Bing is being questioned by Han Cheng and Yu Shan.
"He Bing, do you still remember the friends around Bai Tian? Is there anyone 1.8 meters tall?" Han Cheng asked.
"Baitian is a boring person. He doesn't have many friends. He only has one or two close friends. They are all his childhood friends. They are all southerners and not tall. He has no friends who are 1.8 meters tall!"
"Did he have any unusual behavior before he was killed? What was his financial situation at the time? Was he short of money?"
Han Cheng asked because he wanted to understand Baitian's motive for committing the crime. For a person with no robbery record to suddenly reach this point, it must be that something happened in his life.
"I didn't see any abnormal behavior. To say that I was short of money, it was considered a shortage! At that time, we were already talking about marriage, and my family asked him to give a gift of 100,000 yuan! But he only had 50,000 yuan in hand at that time, and the money was not enough. , our marriage had to be put on hold for the time being! But he said he would make money soon!"
"What happened next? Did he make money?"
"No! Not only did he not make any money, he also used the 50,000 yuan he saved to speculate in futures. In the end, he lost even his principal! I was very disappointed with him at the time, so I broke up with him decisively!"
"Have you had any contact since then?"
"We had contacted each other a few days before he was killed. He took the initiative to find me and said that he wanted to get back together with me. He also said that he would make a fortune in a few days. Not to mention a gift of 100,000, it was a million. The bride price is no problem for him!"
"Then have you asked him how he made a fortune?"
"No, I just thought he was crazy and crazy. He was just a driver and his salary was just that little. How could he earn a million right away?"
Thinking of this, Han Cheng had already guessed what Baitian's plan to get rich was.
He must be trying to rob his employer, Cao Jing, by joining forces with the Hammer Madman.
"When he last met you, was there anyone following him?"
"This... let me think about it!" He Bing recalled for a while and suddenly said, "I remembered that there was actually a person following him. That person seemed to be quite tall. Judging from his body shape, He looks a bit like a Northeastern person! But after he saw me, he walked aside. Could he be the hammer-headed maniac you are looking for?"
He Bing's face changed in shock.
"He Bing, think about it carefully, do you still remember what that person looks like? This is very important to us!" Yu Shan asked hurriedly.
"The man looked to be in his thirties, with a square face, a short haircut, wearing a pair of camouflage shoes, and a mole on the corner of his right eye..."
While He Bing was telling the story, Han Cheng started drawing on the paper.
After He Bing finished describing the tall man's appearance, Han Cheng had already drawn a portrait.
"He Bing, look at it, does it look like this person?"
Han Cheng handed the portrait to He Bing.
He Bing looked at it carefully and said, "It looks like it! I think it looks very similar!"
"Are you sure?" Yu Shan was dubious.
After all, more than twenty years have passed, and most people rarely remember the appearance of a stranger they have only met once.
"I work in the beauty industry, and I pay special attention to people's faces. That person's face looks very special, so I have an impression!" He Bing affirmed.
Hearing what He Bing said, Han Cheng and Yu Shan were very excited.
Because this means that after searching for so long, they finally found the key information about the Hammer Maniac, his appearance.
