The man looks honest, and his eyebrows and eyes are somewhat similar to Rui'er.

Therefore, Su Jin guessed his identity at a glance.

The man hesitated in his eyes and did not open the door, looking back and forth at them.

"Police, open the door!" Yuan Ke flashed his police ID.

The man's face was shocked, and he immediately opened the security door, "Two police officers, what's the matter?" ”

"Are you Manager Qin?" Yuan Ke looked at him.

"What kind of manager, it's the cleaning department in charge, and it's just a cleaner." He is very modest, has a simple smile, and looks like an honest man.

"Are you familiar with Cheng Fangfang?" Yuan Ke took out the record book and asked while remembering.

"We're all colleagues, of course we know each other."

"Do you know that Cheng Fangfang was arrested?" Su Jin spoke, and she stood at the top of the stairs, two or three meters away from the door.

"Yes." Speaking of this, Qin Dongyang's face became heavy, "Rui'er came back and said, I didn't expect that such a kind person would actually kill someone...... Alas, she also has a son with autism, who is also a poor woman......"

He sighed, his words full of regret.

"Just now your daughter said that you went back to your hometown, why did she lie?" Yuan Ke asked with a calm face, feeling more and more that there was something wrong with the father and daughter.

"Officer ......" Rui'er in the house ran out, stood beside the man, and explained, "I quarreled with my father, and I was angry that I said so!" ”

"Angry?" Yuan Ke sneered, "Lie to the police, do you know what the consequences are?" ”

"I'm sorry, I'm sorry, this kid of hers is used to being willful, please forgive me comrade police." The father bent down to apologize and was sincere.

Yuan Ke frowned, and Su Jin, who was behind him, suddenly said: "If it's really a quarrel, it's good, I'm afraid that someone will deliberately lie." ”

The father and daughter looked at her, and Su Jin stood there, her eyes staring at them closely, her dark eyes shining with essence, enough to penetrate people's hearts.

"Manager Qin, where are you on August 2nd?" She asked.

"I'm ...... in my hometown," Qin Dongyang replied, "Wushi Liyang County." ”

"It's two or three hundred kilometers away from the Imperial City." Yuan Ke had excellent geographical knowledge and immediately told Su Jin the distance.

"When did you come back?" Su Jin continued to ask.

"This morning."

"Are you sure?"

"Yes, I have a high-speed rail ticket, I can prove it." Qin Dongyang said, turning around and going to the living room.

Soon, he came out with a train ticket.

Yuan Ke took it back and nodded.

Su Jin squinted, she didn't speak, and turned around and went downstairs.

After walking a few steps, she turned back and stared at the man, "I hope you are telling the truth." ”

Then, step downstairs.

Yuan Ke put away the pen and paper and said to the father and daughter: "If you have any questions, I will talk to you again." ”

She walked downstairs quickly to see that it was still early, and Su Jin asked her if she had Manager Yin's phone number?

Yuan Ke had his business card, and Su Jin used her mobile phone to call the manager and obtained the contact information of a cleaner from the manager.

She immediately called the phone, called the other party several times before answering, and heard that it was from the police station, and the other party was very cooperative and gave her home address.

The male cleaner does not live in the city, and his home is in a small town between the club and the city, which is about an hour's drive.

At nine o'clock in the evening, the town was deserted, and families stayed at home.

Close to the mountains, the night in the town is quite cool, cool and breezy, away from the hustle and bustle of the city, a single family, and a comfortable life.

Yuan Ke found the home of the male cleaner and parked the car on the side of the road.

The male cleaner was already waiting at the door of the house, and when he saw them, he ran up to greet them enthusiastically.
