Hearing this conclusion, Sun Bingxin did not show a too surprised expression. The corpse looked terrible, as if killed by a car, but could not conceal his knowledge.

I took a look at the wound near the temple, and it felt like a round object with edges and corners. My first reaction was the ashtray, but judging from the background sound during the call, it was on the road, and a man was holding the ashtray on the road to commit assault?

Sun Bing stunned: "The murderer smashed him to death on the road, which is too arrogant!"

I said, "More exaggeratingly, the weapon may be an ashtray ..."

"Really?" Sun Bingxin was surprised for a while: "Do you think this murderer is that murderer?"

"Perhaps there are no chances, otherwise he has no meaning."

I groaned. The murder was heard on the phone, but I got this conflicting information. What went wrong?

I looked at the body and suddenly said, "Right hand!"

In the two previous cases, the murderer was undoubtedly left-handed, but it was the right-hander who killed the fat man. The murderer 20 years ago was also right-handed.

Although the murderer wrote the words "I am back" on the body, I was never convinced that he was the person. If it was him, he had deliberately trained his left hand for 20 years, but Jiang Shan was easy to change his nature. In very urgent situations, he still used his right hand.

This makes perfect sense.

I quickly took off the rubber gloves and said, "I have to go back and listen to the recording!"

Sun Bingxin asked, "What does this man do? It's not true."

I said, "There is no need to continue the examination. The corpse will be returned later. The forensic doctor in the bureau wants to dissect freely."

As I was about to go out, Song Heting suddenly said, "What did you forget?"

Then I remembered burning paper. I burned it every time. The only time I forgot to get caught was Song Heting. I took out the yellow paper with embarrassment on my face and lit the deceased. When it was burned, Song Heting also folded his palms and chanted the curse of life with me.

We first went to the bridge to find Huang Xiaotao. She was holding a mobile phone and taking pictures. She was surprised to see us coming and asked, "You're done so soon."

I said, "That man was murdered, not a car accident!"

"Really?" Huang Xiaotao raised an eyebrow. "No wonder I found no trace of the accident for a long time."

The bridge is very old, and some of the railings were damaged, but it can be seen from the rust on the fracture that it was not damaged yesterday. Sun Bingxin looked around and said, "There is no place to hide."

I looked at the passing cars and analyzed: "There is also a lot of traffic. I am afraid that there are more cars at 8 or 9 pm ... The place of murder is not on the road, it should be elsewhere."

Huang Xiaotao asked, "Why not another road?"

I smiled bitterly: "Use an ashtray as a weapon on the road?"

Huang Xiaotao said: "It may not be an ashtray, such as a flower pot on the roadside."

I shook my head: "It must be an ashtray, I won't even recognize this."

Sun Bingxin interrupted us and said, "There is no way to argue here, isn't it to go back to the recording and go!"

Song Heting smiled when he left, and I asked curiously: "Aunt, what are you laughing at?"

She said, "You think the three of you are quite tacit, oh, it's nice to be young!"

I caught the opportunity and praised it: "I don't think my aunt is old at all."

Although Song Heting denied it by mouth, she could see that it was very useful from the expression. Sure enough, women love to listen to such words. I am proud of the growth of my emotional intelligence.

Back in the bureau, we asked the technician to tune out the recording and listen to it. The 28-second recording was input into the program and turned into several tracks, which were slowly played. No matter how you listened, the road in the background The sound was clear, as if on the road.

I asked, "Can you separate these voices?"

"It will take time!" The technician replied, "But I have found that the curve of these car sounds is relatively smooth."

"What do you mean?" I frowned.

"The sound of the car itself is noise, which is a dissonant sound wave, but the recorded part seems to have been subjected to noise reduction." The technician was puzzled.

Sun Bingxin slaps his hands and suddenly realizes: "I see. It was intentionally faked by the murderer. This car sound was actually released by him."

I laughed: "Who has such great patience, knowing that the police will call in advance? The reason for the noise being reduced is very simple, because the sound is filtered by a layer of glass, and the murder location is actually indoors."

I asked the technician to play it again. When I heard it at the end, I called and stopped. I said, "Notice that when the phone landed, there would have been a loud crash, but it was not in the recording."

Huang Xiaotao said, "You mean, there is a blanket on the ground."

I nodded: "It is possible, there is another possibility, the dead is sitting, such as sitting on the sofa, the mobile phone is cushioned by the cushion."

Huang Xiaotao said: "Or have both a blanket and a sofa."

The technician played it again. When the murder happened, the harsh blind sounds drowned everything, but there was still a muffled sound from it, which should be what I said was that the mobile phone fell on a soft object.

Sun Bingxin asked, "What about this particularly harsh sound?"

Huang Xiaotao laughed: "That's not easy. The murderer broke his phone with his shoes."

"So it is!"

This is a subversive discovery, which means that the murderer was sitting face to face with the deceased at the time, and they were very familiar with each other until the murderer approached behind him with an ashtray, and the deceased would not doubt it.

Huang Xiaotao stood up in excitement and shouted: "Walk around! While they are catching the unlucky child and searching for it, let's accidentally get rid of the real murderer!" She also told the technical police who released the recording and called He couldn't reveal a word.

When we came out, we all felt inexplicably excited. The ghost-like murderer was so close to us for the first time in history!

On the way to the deceased's house, Huang Xiaotao called Wang Yuanchao, who did not know where to go, and asked him to come over to help him, but Wang Yuanchao said he had something important, and Huang Xiaotao complained after hanging up.

The deceased named Wang Wuxi, a section chief of a grain and oil company. We spent a day visiting his home, his company, and learned that he and his wife had been separated for a year. No one knew where he went last night. In fact, he has always been a very serious and decent person in front of his colleagues. No one knows that he has S-M preferences, let alone his relationship with Li Lanlan.

With great expectations, we took a break, and that kind of psychological gap can be imagined. Just then, we got the news that there was significant progress over the fat police officer, and Ma Qiaojun had pleaded guilty!
