Chang Ping and the three of them walked to the entrance of the alley and saw Zhang Xing and the three of them standing in the alley, and they heard the footsteps and looked at them.

"What kind of clues?" Chang Ping looked at Zhang Qi.

"You can see it from the door!" Zhang started to turn around and pointed to the courtyard with the door open, and Chang Ping turned on the mobile phone flashlight again and shone it into the courtyard.

"There are traces of dragging, although some of the footprints have disappeared, but some places can still see the footprints of two people when they go in, but there are no footprints when they come out!" Liu Yang pointed to the ground and said.

A man-wide trail of dragging on the ground faintly showed intermittent footprints underneath the trace. The footprints are large and small, and it can be inferred from this that they are two people.

"Judging from the footprints, one person's height is around one meter seventy-five, and the other should be between one meter six and one meter seven!" Tuya looked at the footprints on the ground and reasoned herself.

"What's going on inside?" Chang Ping looked up and shone a flashlight at the house.

"The traces of waiting inside are similar to the outside!" Zhang started to reply.

"Let's go, go in and have a look!" Chang Ping said and walked towards the house. The door was open, and I tried to bypass the marks on the ground and entered the house, only to see some marks in the doorway, and a string of them went inside.

Chang Ping looked at these traces and a scene appeared in his mind. The man hurriedly ran over after receiving the call, the caller waited at the door, and when the man arrived, he walked to the house with him, and after opening the door, the man went into the house first, and the caller directly knocked the man unconscious with a prepared blunt object at this time, and then went into the house and took out the prepared rope to tie the man up, and then dragged the man out.

"From the footprints, it can be inferred that the culprit should be a woman!" Tuya looked at the crowd and said.

"That's right, if it's a man, he should have a lot of strength, in order not to leave a trace, he will definitely resist the fainting person, a woman of one meter six to one meter seven does not have so much strength, so she will drag the victim out!" Chang Ping nodded. "Are there any other clues?"

"Yes, there must have been fingerprints left on the doorknob, and someone from the Evidence Department has been contacted to collect it!" Zhang Qiqi nodded and said.

"There were no clues in the house, because they didn't linger after knocking people unconscious." Liu Yang said.

"Who is this householder?" Li Chaonan asked.

"I asked, it's an old man named Wu Yongfu, who was picked up by his son and never came back to live!" Tuya replied.

"Do you know where to stay?" Xiao Lizi asked.

"Know, I'll go over when I'm done collecting fingerprints!" Liu Yang replied.

"Don't wait, leave two to wait here, the others will go directly to investigate, tonight's toss will be over if the suspect knows!" Zhang Qiqi looked at the crowd and said.

"Then Xiao Lizi and I are waiting here, you guys hurry over!" Liu Yang glanced at everyone and said. Xiao Lizi still wanted to refute it, but when he saw these people, he closed his mouth, one was the captain, the other was Chang Ping, and there were two women, so it was not appropriate for any of these people to stay.

"Okay, let the Evidence Section make the fingerprints as soon as possible!" Zhang started to explain.

"Okay, got it!" Liu Yang and Xiao Lizi nodded at the same time.

"Jingle jingle bell" A doorbell rang in the corridor, and Zhang started the four of them standing in the corridor staring at the door.

The faint sound of footsteps walked to the door and opened the door, and a man in his thirties looked at several people with sleepy eyes. "Who are you? Who are you looking for? ”

"You're Wu Yongfu's son, right? We are from the Municipal Public Security Bureau! Zhang Kai showed his ID.

"What's the matter?" The man asked, frowning.

"That's right, your father's house is involved in a kidnapping case, and we're here to investigate!" Li Chaonan looked at the man and said.

"My father's house? Kidnapping? The man looked at the crowd in bewilderment.

"Yes, we need to investigate!" Zhang started nodding. "Can we go in?"

"Oh, wait a minute, everyone in the family is asleep!" After the man finished speaking, he turned over and entered the house, Zhang started and the four of them followed into the house and stood in the living room, the man stood at the door of a bedroom and called his father, and a woman in her thirties came out of the other bedroom, and looked at the four people standing in the living room and asked the man what was going on.

"Investigating the case? What case is being investigated? The woman looked at the four of them.

"A kidnapping case, clues were found in your father's yard!" Li Chaonan replied.

"Ouch, it wasn't my father who did it, he's so old and doesn't have the strength!" When the woman heard this, she hurriedly defended.

"It's still investigating, so you'll need your father's cooperation!" Zhang started to reply. When the woman came out, Chang Ping and Tuya both looked at her, measured their height and looked at her feet.

"How is this?" An old man with half-white hair walked out of the bedroom, looked at his son and asked, and after asking, he saw Zhang Qixing and the four people standing in the living room.

"Your old house is involved in a kidnapping case, they are the police, come to investigate!" The man who opened the door earlier replied, Chang Ping and Tuya stared at the old man again, and after reading it, they shook their heads slightly.

"What? Kidnapping? What the hell is going on? The old man's eyes widened instantly, and he looked at the four of them.

"Old man, how long has it been since you been back to that house?" Zhang Qiqi looked at the old man and asked.

"My dad hasn't been back since he moved to me!" The man replied.

"Does anyone prove it?" Zhang Xingxing looked at the man.

"Yes, the old men and old ladies in this community can prove that my dad will exercise with them tomorrow morning and move together in the evening!" The woman replied.

"Have you two been there, then?" Li Chaonan looked at a man and a woman and asked.

"We haven't been back, we can't get in even if we do, the key has always been with my dad!" The man replied.

"The keys are always with you?" Zhang Qiqi looked at the old man again.

"Yes, it's always been with me!" The old man nodded back.

"Have you ever given it to someone else?" Chang Ping asked.

"To someone else?" The old man wrinkled in thought. Everyone in the room looked at him. "I gave it to someone."

"To whom?" Zhang Qiqi's eyes immediately lit up.

"About a month ago, my daughter asked me for it, saying that one of her classmates wanted to use it, and she sent it to me when she ran out!" The old man looked at Zhang Qi and said.

"Do you know who your daughter's classmate is?" Li Chaonan asked excitedly.

"I don't know, I have to ask my daughter!" The old man shook his head.

"I'll call my sister!" The man said as he walked to the bedroom.

"Don't fight!" Zhang Qiqi called out to the man. "If you call your sister now to alert the criminal, it won't be easy to find!"

"What then?" The woman asked eagerly.

"In this case, please follow me to your sister's school to find her!" Zhang Xingqi looked at the man and said.

"Okay, I'll go change my clothes!" After the man finished speaking, he entered the bedroom, and waited for the man to change his clothes and leave the community.....
