crime profiler in the dark

three days later

During these three days, Bai Haolin's mind was full of "voluntary policemen". He had too many worries and worries, but he also had more reasons to take this risk. After three full days, now it's finally time to see the outcome! !

At eight o'clock in the evening, Bai Haolin returned home.

Everything in the house was as usual, and there was no sign of forced entry. Bai Haolin observed every inch of the house, but did not see any clues. Could it be that the "violent policeman" was not fooled?Or can't find a way to get in?

Bai Haolin walked into the study room full of doubts. The documents were still lying on the corner of the table, in the same position as when he left, without any trace of movement.

Did I guess wrong?Bai Haolin began to question his actions.

He walked to the desk with some frustration, and when he saw the document, his glum mood disappeared immediately, and the corners of his mouth turned up slightly——Bai Haolin clearly remembered that he had slightly opened the document before leaving, and put it away. The paper on it happened to cover the characters "人" in the first row and the word "可" in the last row, and now, these two characters jumped into my eyes, which meant that someone had touched his document. , just put it back in place with the utmost care! !

Bai Haolin hurried to the bookshelf. At first glance, although the books did not show signs of being moved, Bai Haolin was sure that the "violent policeman" must have opened the frosted sliding door.

The sliding door of the bookshelf is very distinctive. In order not to spoil the beauty, the handle of the sliding door is not protruding outward, but concave inward, and the recess is extremely shallow. If the "vigilante" wears gloves, they must be removed In order to ensure that there would be no deviation, Bai Haolin had already cleaned up all the original fingerprints in the room before leaving.Presumably, when Bai Haolin's father ordered this bookshelf, he did not expect that this ingenious design would turn things around for his son now!

Bai Haolin removed the sliding door, took out the black powder borrowed from the support department, and gently brushed it on the recess with a paint brush. After a while, a clear fingerprint appeared in front of his eyes. Since the recess was extremely shallow, the fingerprint was only 2/3 of the portion was left.

Bai Haolin took a sample of this half of the fingerprint and carefully placed it close to his body.This is the first step for him to know the "violent policeman". If his information can be found in the police's fingerprint identification system, it will be the greatest progress for him! !
