It makes sense for the delivery boy to appear at the crime scene, right?

"Teacher Du, this is my brother, today he sent me to class... You don't mind if he sits in, do you? He can also play the piano..."

Chen Xiao looked at Du Min a little nervously, fortunately Du Min did not pay attention to her.

Du Min smiled and said, "Is it? Why haven't I heard you say it before, come in quickly... Why didn't Fang Chengcheng come with you..." At

this time, Du Min's phone rang, it was Fang Chengcheng who called, asking for leave.

Su He smiled and walked into the house, there were two pianos in a small living room, the room was very neat, the curtains were open, the sun was shining, and the flowers on the dining table exuded a faint fragrance.

Su He sat on the sofa, and Du Min poured her a glass of water.

"Chen Xiao, first play the song from last week..." Du

Min took a few fruits from the refrigerator and went to the kitchen, Chen Xiao saw this, pointed to another piano, and immediately began to play.

"Wrong, start over!"

As soon as Chen Xiao started, Du Min's voice came from the kitchen.

Su He got up and walked to another piano, gently stroked the keys, and sat down.

This

was Su He's first time playing the piano, and on the wall, a yellowed sheet music was only half written.

Du Min stood at the kitchen door, looking at Su He playing the half of the song on the wall in amazement, Su He played more and more smoothly, but as the score ended, he did not stop.

The tune of one part chases the other until the last bar, the last chord, merges together.

The sunlight shone on Su He's face, and Chen Xiao watched mesmerized on the side, and the recurring notes sounded in her ears like gentle whispers.

Before you know it, the melody has risen an octave, and then subtly replies.

Finally, the piano sound stopped abruptly, Su He shook his head regretfully, and sighed: "The lingering and ultimate music is like two souls blending together... Teacher Du, what makes you unable to let go?

Du Min's face changed instantly, and he glared at Su He and asked, "What do you mean?"

Su He got up and pressed a black key on it and said: "If a key is broken, the song will be incomplete, Mr. Du, do you think what I said makes sense?"

At this time, someone knocked on the door, and Chen Xiao ran to open the door.

"Hello, Ms. Du, we are from the Criminal Investigation Detachment, and we have searched your residence according to the law, this is a document, I hope you will cooperate..." Officer Rong stood heroically at the door, and then several policemen walked in.

The fruit plate in Du Min's hand fell to the ground, the fruit rolled everywhere, she tugged on the corner of her clothes, and said nervously: "Officer, be careful, don't break things..." Rong

Xue walked to Su He's side, glared and said: "Who let you act without permission?"

Su He smiled and pulled Chen Xiao out.

Outside the door, Su He touched Chen Xiao's head and said, "Go back!"

Chen Xiao looked up at Su He and said with a smile: "I completed the task, is there no reward?"

Su He took out two dollars from her pocket and put them in her hand, and said: "Go, buy a popsicle in the supermarket downstairs to eat, pay attention to safety on the road..."

Not long after, as the piano was opened, Rong Xue was stunned.

A dry corpse of a baby!

"Nope! ... I beg you... Give my daughter back..." Du

Min was taken into the police car.

Back at the Public Security Bureau, Du Min refused to answer any questions, just repeated: Give me my daughter back.

Rong Xue took a stack of materials and handed it to Su He and said: "Five years ago, Li Di domestic violence Du Min, who was eight months pregnant, caused the baby to be born prematurely and eventually died... The obstetrician-gynecologist violated the operation, did not follow the hospital process, and should have been handed over to the funeral home for cremation, but privately traded to Du

Min..." ""At the murder scene, the murderer was wearing Li Di's shoes, Li Di's shoes were 43 yards, Du Min's feet were 37 yards, and the footprint identification results showed that the murderer's feet should be around 42 yards..." Different size feet, wearing 43 size shoes

, the footprints left behind are not the same, in the wasteland, the depth of the footprints, in the economic investigation technology, Information such as height and weight can be roughly restored.

Li Di's domestic violence against Du Min led to the death of the child in Du Min's womb, Du Min held a grudge, and the motive for killing was established.

But the motive for killing alone is not enough, and there is no evidence to identify Du Min.

Size 42, size 43 is a common size for men's shoes, depending on the size, there is no way to locate the suspect.

Du Min kept silent and refused to cooperate with the police's questioning.

Not long after, Du Min's boyfriend was summoned by the police.

He Zhengchu, male, 34 years old, attending physician of a pet hospital, and Du Min are college classmates, after Li Di and Du Min divorced, the two lived together and have not yet obtained a license.

In the interrogation room, Officer Zhao asked, "He Zhengchu, do you know that Du Min's piano is hiding something?"

He Zhengchu shook his head and replied, "I don't know." "

How did the injury on the back of your hand come from?"

He Zhengchu smiled, raised his hand and said: "Last night, a customer's dog was delivered, and it was not saved... In the end, the customer made trouble and got into a fight... All police records were dispatched, and I also compensated 2,000 yuan..."

After some questioning, Officer Zhao walked out of the interrogation room.

Glaring at Su He, he said, "Why are you still here?"

"Officer Zhao, I... I do not share heaven with sin!

"Okay, this clue of Du Min, if you can finally lock the murderer... The 100,000 yuan clue collection reward is yours, go back first! "

Okay, Officer Zhao, then you are busy, I won't disturb your work..." As

soon as Su He left the Public Security Bureau, Officer Zhao brought a few police officers to the pet hospital where He Zhengchu was.

"Hello officer, this is the dispute that happened last night... But we have dealt with it, and the parties have accepted our apology and compensation..." The head of the hospital called up the video and handed over the settlement between the two parties.

In the surveillance video, a man ran into the hospital holding a puppy, and soon He Zhengchu began to treat the puppy, but the treatment room was not monitored, and 27 minutes later, He Zhengchu came out and told the dog owner that the dog died.

The dog owner couldn't accept it for a while, and made a fuss in the hospital, He Zhengchu stepped forward to persuade, and after a few words, the two fought.

Then the front desk called the police, the police came, and after some mediation, both parties apologized, and the hospital compensated the dog owner for 3,000 yuan.

Among them, there were 2,000 yuan, which He Zhengchu compensated.

It seemed that this was an ordinary treatment dispute, and Officer Zhao suddenly said when he played the second video: "Stop! Go back five seconds... Two more seconds back... That's it! In

the picture, He Zhengchu took off his gloves before fighting with the dog owner, and it can be vaguely seen that there are blood-red marks on the back of his hands.

Officer

Zhao looked back at the person in charge of the hospital and asked, "Last night, was there anything wrong with He Zhengchu?"

"Nothing... Oh, by the way, under normal circumstances, in this case, the attending physician will not show up, Dr. He, he is indeed a little abnormal, and he fights with customers..."
