Chapter 172 The Missing Hard Disk

As Qin Ruonan walked towards Anchangpu, he took out the small plastic bag that he often carried with him because of his professional habits, and carefully put the things in his hand into it.

"Look," she handed the plastic bag to An Changpu, "I'm sure it's definitely not Song Chengliang's."

An Changpu took it from her hand, one second he was wondering why her tone was so firm, and the next second he couldn't help laughing.

There are a few strands of hair in the plastic bag, the hair is very long, at least fifty or sixty centimeters long if straightened, and the hair is brownish red. Obviously, the owner of the hair is a woman, and a young woman who has dyed her hair—— That bright reddish-brown color is definitely not something that ordinary middle-aged women can dare to challenge.

"Where did you find it?" He asked Qin Ruonan.

Qin Ruonan pointed to the bedroom: "I just checked the gap between the bedside table and the bed. The top of the bed and the pillows were all tidy and clean, so I moved the bedside table a little. That place is a It was a place where dirt and dirt were often hidden, and people often neglected to clean it, but I did not expect to find something.”

"Smart! Now it's your turn to see what I found." An Changpu praised Qin Ruonan, turned around and walked to the sink in the bathroom, pointed to the small table where the sundries were placed, several bottles of men's cleansing and skin care He had just moved away the supplies, revealing an empty space.

Song Chengliang's sink is covered with some kind of black matte stone. Qin Ruonan leaned over to look, but found no obvious traces. She turned her head and looked at An Changpu with questioning eyes. An Changpu didn't reveal the answer. , just motioned her to take a closer look.

She had no choice but to turn her eyes to the small empty space vacated by An Changpu again.

Qin Ruonan leaned down and took a closer look. The matte black material has a very good concealment effect. Slight stains or even damage may not be so easy to be seen. She looked at it and felt that there seemed to be some traces on it. He couldn't see clearly, so he squatted down halfway, so that his line of sight was almost parallel to the countertop, and then he saw that there were two inconspicuous, even incomplete, circular marks on it.

"The bottom mark of the cup?" She stood up and asked An Changpu.

"Yes, I think so, but look," An Changpu took the cup with a toothbrush inserted in it and put it on the place with the mark on the bottom of the cup, "No matter the shape or size, it is obviously not suitable. .”

There is only one cup in the bathroom of Song Chengliang’s house, with a toothbrush and a tube of toothpaste inside. This is the state of people who obviously live alone, and the cup is a square cup with rounded corners, thick on the top and thin on the bottom. The bottom of the cup is the same rounded square shape, and it is absolutely impossible to leave such a standard round mark.

"It doesn't seem impossible if you change the toothbrush cup." Qin Ruonan was a little uncertain about An Changpu's discovery, "Also, it's impossible for everyone to put their cups regularly every time. Put it back to a fixed position, so the two bottom marks on the cup can't mean that it must be related to his cohabitant?"

The reason why Qin Ruonan was obsessed with such details was not for nothing. She found the long dyed hair, which only showed that Song Chengliang once brought a woman home to spend the night, but he couldn't deduce from this that the woman must have lived with him. , but if the trace of the water cup found by An Changpu obviously could not be formed in a day or two, if he can prove his conjecture, then it is almost certain that Song Chengliang had a cohabitant in the first place.

Therefore, the question of whether the inference can be established must be cautious and rigorous.

An Changpu shook his head, motioned Qin Ruonan to lean down again, and revisited the two round marks with himself, and showed her with his fingers: "Look, there is a gap between the two somewhat incomplete round marks on the bottom of the cup. There is a very short distance, they are not close together, and there is no overlap. If you, unconsciously, place the water cups randomly as you just assumed, it may leave a difference The two bottom marks of the cup, but can you guarantee that the two marks are completely non-overlapping and intersecting?"

Qin Ruonan thought for a while, then quickly shook his head.

"So, unless that's the case." An Changpu clenched his empty fists with both hands, gestured as if they were two water glasses, and then put them together on the table. It is a cup with the same diameter from top to bottom, and because of the thickness of the cup wall, the bottoms of the two cups cannot be completely joined together, if you don’t believe me, you can try it at home.”

"Why are the traces so shallow and incomplete?" Qin Ruonan felt that An Changpu's analysis was reasonable, and at the same time she was curious about the traces that were almost hard to detect, "Do you think it was done on purpose, or was it cleaned?" because of?"

"It's really hard to say. You see, just like the last toothbrush cup used by Song Chengliang before his death, there are two possibilities. One is that someone took away the old cup in order to cover up the past cohabitation life, and replaced it with a new one. I bought a new one and wiped the traces, but the cleaning was not thorough. Another possibility is that the cohabitant and Song Chengliang broke up and moved out, so the original pair of cups were replaced. As each episode was cleaned, The traces are gradually fading. But since we can infer that there is a woman coming and going in Song Chengliang's house, this question can be verified after we find the cohabiting woman." An Changpu is not in a hurry to find out a conclusive answer.

"Then let's take a look around."

The two looked around the house again, and soon they discovered another thing, something that hadn't been highlighted in the photos of the scene before.

Song Chengliang’s house has two bedrooms and one living room. Besides the bedroom, there is a small room with a computer desk, a chair, and a small bookcase beside it. These three things are The room is almost full.

The situation in that small room was as tidy and clean as the outside. If Qin Ruonan and An Changpu hadn't checked carefully this time, they would have almost ignored the problem that should have been discovered long ago.

"Where did the hard disk of Song Chengliang's computer go?!" An Changpu was the first to discover this problem. He squatted down, pulled out the main chassis that had been pushed deep, and removed the main chassis that was not fixed with screws but was only concealed on it. box panel.

Song Chengliang's computer desk is a large and luxurious desk that can almost be called the boss desk. The desktop is very wide, and the space under the desk is naturally deep. The power cords are entangled and stuffed in the deepest place under the desk. The box was also pushed into the corner under the table. If An Changpu hadn’t pulled away the thick and high back of the boss chair and bent over to check it, he might have overlooked the main box in that corner, let alone Says if the top panel is secured with screws.

Qin Ruonan also walked around behind the table and squatted down to take a look. Sure enough, there was an empty space on the main box where the panel was removed by An Changpu. She didn't understand the structure of the computer, but she just instinctively felt that something appeared in a computer. It is wrong to have a large vacancy. If An Changpu hadn't said that, she probably wouldn't know that the space was for installing a hard disk.

"Here," An Changpu knew that she didn't understand computers. Although he was not an expert, at least he knew a thing or two compared to Qin Ruonan, so he explained to her, "The hard disk of the computer should be installed in the first place. The ones here must have been dismantled, not only the hard drive, but also the hard drive bracket that houses the hard drive!"

When they took over the case, they had already obtained information from the colleagues who accepted the case and showed up at the scene. Like ordinary murder cases, Song Chengliang's house was wiped and sorted out, leaving no obvious clues of fingerprints and footprints. The lock of the anti-theft door is just like what they saw when they came here just now, it has not been pried or forcibly broken, and the lock is intact.

Therefore, the person who can remove the hard drive is either the owner of the house, or the person who can freely enter and exit here, and there is no third possibility.

"Afraid that the things on the computer will be seen by others?" Qin Ruonan guessed.

"That's for sure, but what exactly is it that people are afraid of being seen, is Song Chengliang tearing it down because he was afraid of being seen, or is it someone else who is afraid of being seen, we have to find out again!" An Chang Po squatted there again to check for a while, "The person who removed the hard drive, whether it was Song Chengliang or someone else, must have been in a hurry at the time. You can see that there are cracks in some places on the panel, obviously the screws have not been fully unscrewed before thinking The panel was forcibly pulled off, and the guy didn't even seem to have time to remove the hard drive from the bay."

As he said that, he wanted to stand up. He didn't know whether it was because he ran a lot today, or because he squatted down for a long time. The left leg used to support the weight of his body was a little too strong, and when he was halfway up, he suddenly lost his center of gravity. He swayed, thanks to Qin Ruonan who supported him with his arms.

Qin Ruonan was sure that he had stabilized his body, immediately let go of his hand, turned and walked away.

It's all because of that Tao Yinyin!She is definitely a big evil star of her own vitality!Ever since she appeared, my life, mood, thinking, and everything have been messed up, which made me who didn't have much self-confidence even more disgusted with my inborn, seldom seen. The indecisive personality known to outsiders comes!

An Changpu looked at Qin Ruonan who suddenly turned and left, and frowned. He moved a little at the ankle that was suddenly weak just now, and almost made him fall. Text messages come in.

In fact, it was true. There was a text message on the phone, which was sent by Zhong Han, asking him about his health. By the way, he asked Qin Ruonan to say hello to Qin Ruonan, and told Qin Ruonan to ask her to have dinner with her another day.

An Changpu stared at the message on the phone, the sender was indeed Zhong Han, but, with his personality...

He was a little confused.

"What are you thinking about?" Qin Ruonan turned back at this moment, stood at the door of the small room and looked at An Changpu, pouted behind him, "I heard voices from the neighbors next door, I think we should go and talk to them .”
