"Officer Su, Zhong Zhixin's mother said that the piano teacher lives in Anding Square in the center of the city, and it will take about twenty minutes for us to go there." Zhou Li hung up the phone and said quickly.

Su Tong nodded, "Let's go." ”

After the order was given, everyone was ready to go. When passing by Xu Sa's side, Su Tong whispered: "When the case is over, I will definitely give you the answer, wait for me." ”

Xu Sa didn't answer, just turned around and walked towards his office.

"Officer Su!" The police officer at the door was already calling for her.

Su Tong looked at Xu Sa's back steadily, and then walked to the door.

In the cold key prison, an armed policeman knocked on the stainless steel door with a baton in his hand. "Shang Minghua! Someone has come to see you. ”

Shang Minghua, who had a neat head, put down the glasses that were reading the newspaper and looked at the armed police suspiciously.

The only sound of shackles and handcuffs striking was the empty walk, stiff and harsh.

"It turned out to be Captain Xu, who did I think it was?" Shang Minghua looked at Xu Sa with a smile.

Xu Sa glanced at Shang Minghua and said lightly, "Dean Shang, I haven't seen you for a long time." ”

"I didn't expect you to be the first person to come to see me." Shang Minghua shook his head, with a sigh in his tone.

"Why can't I come and see you? You've taught a good apprentice, and you've tried to get you out of prison. Xu Sa didn't miss the puzzlement in Shang Minghua's eyes, "I'm really curious, how did you start a class in prison?"

"Captain Xu, if you hadn't destroyed my work in the first place, maybe I could have taught him more." Shang Minghua pretended to smile mysteriously and said.

"Who is he?" Xu Sa didn't go around in circles with him, and asked him the question he wanted to know the most.

"You don't know how to appreciate, but a lot of people know how to appreciate, you ask me who I am? I have so many followers, I don't know which one, hahahaha" Shang Minghua let out a wild laugh, "It seems that he is also blue, otherwise you wouldn't have come to me." Good! Good!"

The two prison guards behind him stepped forward to signal Shang Minghua to calm down, but Shang Minghua did not restrain his wild laughter.

Shang Minghua also slapped the table even harder.

Xu Sa watched Shang Minghua being dragged back by two prison guards, and the terrible laughter still lingered for a long time.

Several police cars were parked near the lively Anding Square, and Su Tong and others wore body armor and approached the suspect's residence.

He Xingchen walked to the door of a unit with a pistol, leaned his back against the wall, and counted down to three, "Three, two, one!"

The armed police detachment kicked the wooden door open, and what caught his eye was the living room with the lights dimmed, and directly opposite the door was a curtain of light veil, and the red light on that side was faintly seen.

Su Tong slowly approached, stretched out his hand and lifted the light yarn violently.

Everyone was stunned by what they saw, a large table stacked with glassware and tiny hearts.

"Oh my God." He Xingchen believed that he would be chilled when he recalled it for the rest of his life.

"Clear the scene, call forensic evidence and trace examination." Su Tong made a gesture, all the team members entered, and the voice of the team members came from the ear back, "The investigation is complete, there is no abnormality." ”

"Ding-" Su Tong glanced at his phone, "Hello, I'm Su Tong." ”

"Officer Su, Shang Minghua is dead." The policeman's voice was a little urgent.

"What?" Su Tong's voice caught the attention of Zhou Li and He Xingchen.

"Dead in prison, Sun Ju asked you to go to the prison as soon as possible to understand the situation." Su Tong hastily answered and hung up the phone.

"Officer Su, what's wrong?" Zhou Li asked.

"Shang Minghua died in prison." Su Tong frowned and looked at Zhou Li.

"Isn't it??!" Zhou Li said in shock, "Why did we copy the apprentice's hometown here, and the master over there died?"

"Let's go over and talk about it first." Su Tong said as he unloaded the pistol and put it back into the pouch.

"So where does the medical examiner go first?" He Xingchen asked embarrassedly.

"Let Chen Lao go to prison, and the trace inspection must come here first." Su Tong said calmly.

In the city's key prison for convicts, a single residence for a prisoner was cordoned off in yellow and black, and a small room was pushed open behind the iron gate.

The corpse was sitting with his back to the doorway, his right hand sticking out of the edge of the table, and his right wrist was still dripping with blood.

Elder Chen also arrived not long after, "Elder Chen, I'm sorry for you." Su Tong's earnest tone made Chen Lao want to complain a few words, but he couldn't hold back.

"How could Shang Minghua suddenly commit suicide?" Su Tong asked the prison guard. "Has he had anything unusual lately?"

The prison guard thought for a moment, "Prisoners usually just read the newspaper and say the most unusual things... Captain Xu from your police station came to visit the prisoner this morning. ”

Su Tong looked at the prison guard in surprise, "Captain Xu?!"

The guard nodded and recalled, "Well, I remember that the two of them didn't say a few words, and the prisoner started laughing and banging on the table, and it was me and another colleague who brought him back. ”

"Do you know what they said?" Su Tong immediately asked, and even unconsciously pulled his palm on the other party's sleeve.

"Officer Su, you—" The prison guard pointed to Su Tong's hand in embarrassment.

"I'm sorry, but do you know what they said?" Su Tong hurriedly let go and said embarrassedly.

"I didn't care about listening, but I saw that Captain Xu's expression seemed to be very angry." The prison guard shook his head.

"And when did you find out that he cut his veins?" Su Tong looked in the direction of Old Chen's corpse and asked softly.

"Just an hour after we locked him in his room, because it was time for lunch, our patrolman passed by and found him lying motionless on the table, not even answering his shouts, and as soon as he opened the door and came in, he saw this." The prison guard pointed to the patrolman who was recording a confession next to him.

Su Tong looked in the direction of the prison guard's finger. "Aside from Captain Xu, has anyone else visited him?"

The prison guard shook his head, "Generally, felons are not allowed to visit their families, and the prisoner has been in for so long, and only Captain Xu has come to visit him so far." The prison guard kept trying to recall.

"Did anyone send him a letter or something? Otherwise, where did he get the tools to cut the veins?" Su Tong directly pointed out the loopholes in the prison.

"Well, well, we also often conduct surprise inspections from time to time, and given that the prisoners have always maintained a good obedience record, we do have too negligent supervision of the prisoners." The prison guard said with a grim face.

Su Tong waved her hand, indicating that she didn't want to pursue this. It seems that some questions are better to clarify Xu Sa in person.

Chen Lao quickly walked up to Su Tong and said eagerly, "Officer Su, come with me." ”
