After Ling Fei thought about it for a moment, she nodded: "Okay, I'll notify the people in the trace department."
"Yeah!" Forensic Doctor Li nodded.
Ning Fan followed Ling Fei out and arrived at the police station where prisoners were held.
The place was cordoned off. Ling Fei put on gloves and shoe covers and asked, "Have you found anything?"
"Captain Ling, we haven't found any clues so far," the police officer said.
"Well, let me go in and take a look!"
Ning Fan also put on his shoe covers and followed Ling Fei in. He started to look around and asked, "Where are the police officers on duty?"
"Hu Ba's death time was around three o'clock in the evening. At this time, the police officer went out to get a glass of water. When he came back, he saw Hu Ba dead on the bed."
"What's the time between going out and coming back?" Ning Fan asked again.
Ling Fei continued: "The police officer went to the office building to collect water, and the round trip only took five or six minutes. He himself said it took less than five minutes."
"This time is enough for a master."
"That's enough? The doors from that door to this are strictly locked. How can it be possible to open them all within five minutes?" Ling Fei expressed her doubts.
"Well, because he didn't come in from the main entrance at all, but from here..."
Ning Fan pointed to a window in the detention room. This window was so small that even a woman like Ling Fei couldn't get through.
"Forensic Doctor Ning, is this impossible? The hole is so small that even a child can't get in, right?" Forensic Doctor Li said.
"It's indeed impossible to be a normal person, but what if it's a person who doesn't grow up?"
"A person suffering from dwarfism?" Forensic Doctor Li asked.
Ling Fei paused thoughtfully, then immediately picked up the walkie-talkie and said: "Immediately call out the panic around you to see if there is a person with dwarfism passing by, especially at the intersection behind the police station."
"Let's go, let's go out and see for ourselves!"
Ning Fan and Ling Fei were about to go out, but they stopped just as they reached the door and turned back.
"Ning Fan, what's wrong with you?"
"No, why is there a strange smell here?" Ning Fan smelled it in the room.
"What's wrong?"
Ning Fan smelled the scent of Ling Fei, and Ling Fei was so frightened that she took a step back, covered her chest, and said unhappily: "What are you doing?"
"It's not the smell you carry, but it comes from outside..."
After saying that, Ning Fan walked outside again. This position was already hundreds of meters away from the detention room on the other side, which was beyond the scope of the investigation.
"By the way, do you have a cleaner here?" Ning Fan asked.
"Yes, I have!"
Ning Fan nodded and said, "I made a mistake just now. This person is not a dwarf but a person in disguise. I saw slight marks on the window just now, so my direction was wrong."
"Then what do you want to say?" Ling Fei was a little anxious.
"What time do they start working?" Ning Fan asked.
"Usually at seven o'clock in the evening, they will come to clean the place, and these cleaners have been strictly investigated and screened."
Ning Fan said with a smile: "Hehe, I'm hungry!"
"you......"
These words made Ling Fei blush instantly and said: "Ning Fan, can you help others? If you can't help us, why don't we just waste it with you?"
"Eat first, I'm hungry!"
"Forensic Doctor Li, you should get off work and take him to have something to eat. It's on me." Ling Fei was already disappointed.
"Sister Police Officer, you have to believe me. I can't find anything out now. How about we go have a meal first?"
"If you have no appetite, go alone!" Ling Fei waved her hand.
