Ling Xu stepped on the chair and carefully checked the glass above the door frame, although there were obvious wiping marks on the glass, it was not wiped clean, seeing Ling Xu's expression looking at the glass seriously, Chen Shaochun glanced at him: "Do you think there is a problem with this glass?" ”

"Isn't it suspicious that such a clean and tidy room, even the foot of the bed is wiped clean, but only this piece of glass is not wiped clean?" Speaking of this, Ling Xu pointed to the small stain on the glass surface:

"There's a wipe on this piece of glass, but I don't know why? The person who cleaned the glass didn't wipe it clean, was he too lazy to wipe it? Still don't have time to rub? According to the degree of cleaning in this dormitory, the cleaner is obviously a person who loves cleanliness, so Pie ruled out the factor of "too lazy to wipe".

Since it's not that the cleaner is too lazy to wipe the glass, it's that the other party doesn't have time to wipe it, so the problem arises, the other party has time to clean even under the bed, how can there be no time to wipe this piece of glass?

Also, according to Li Yanxin's former roommate Liu Xia, the deceased Li Yanxin was not a person who liked to clean the dormitory, she never did these jobs, and often supported others to clean the dormitory.

The people of the criminal police team also investigated similar clues, after Li Yanxin moved to dormitory No. 49, she had many conflicts with her roommate because of cleaning, and the roommate moved out of the dormitory when she couldn't bear it anymore.

Therefore, Li Yanxin, a lazy young lady, cannot take the initiative to clean the dormitory, and even if she cleans the dormitory on a whim, it is impossible to clean it so cleanly and thoroughly, this level of professionalism is already comparable to the cleaners of the cleaning company. Ling Xu said lightly.

"What do you mean?" Chen Shaochun looked at Ling Xu.

"The sanitation of this dormitory was cleaned by the murderer." Ling Xu said in a solemn tone: "After the murderer killed someone from here, in order to cover up the evidence, this dormitory was cleaned in all directions.

The killer cleaned all the corners, but for some reason, she didn't have time to wipe the glass, which left many small stains on it, and although these small stains were inconspicuous, they were the only traces that the killer did not wipe off. ”

Speaking of this, Ling Xu became more and more serious about the glass inspection: "Since the murderer left traces on this piece of glass, it means that this piece of glass is not ordinary, and there must be something we need on it." ”

Seeing Ling Xu's actions, Chen Shaochun sighed: "You don't have to look for it, I saw the report and photos of the on-site inspection last night, and this piece of glass is also within the scope of the technician's inspection, and after technical inspection, there are no fingerprints on it." ”

"I didn't look for fingerprints, since the murderer wiped this piece of glass, he must have wiped off her fingerprints." After answering this, Ling Xu stopped speaking, and continued to carefully inspect the piece of glass, when Ling Xu checked the corner of the glass, suddenly, he found an inconspicuous small eye in the gap under the glass.

After careful observation, Ling Xu recognized that this was a nail eye, when installing glass on the door frame at the beginning, in order to fix the glass, the workers would nail several small nails around the glass, and this small eye was a nail eye.

He checked the nail eye with his hand and found that the scraps inside were very new, and then, Ling Xu's eyes suddenly lit up, he seemed to think of something? Start inspecting those little nails around the glass one by one.

After the inspection, Ling Xu looked at himself, then at Chen Shaochun, and saw that Chen Shaochun was holding a stainless steel water cup in his hand, he took the water cup over, made a nail posture, and knocked the door frame under the glass with the glass.

When the water cup hit the wooden door frame, there was a "knock knock" sound.

As soon as this voice came out, Mo Wanqing rushed out of the dormitory opposite, and she looked at Ling Xu with an excited expression: "This is the voice, the knock on the door I heard that night is this voice." (To be continued.) )
