Lu Jinping leaned over to check the jewelry box, which was made of wood. The black paint strokes are also exquisite. He groaned slightly, and said to Patriarch Jin and Mrs. Jin next to him, "Please give me a separate room, I will use the Dao method to inspect this box." ”

"Daofa?" Patriarch Jin was puzzled.

Xiong Zhutou, who followed behind, said triumphantly: "You don't know, our lord has learned a special method of solving cases from the Yunyou Daoist, which is very powerful, the lord has used this method to solve several cases!" Our Luo Judiciary, including Feng Tingshi, are very appreciative, so Feng Tingshi approved the document to let the lord assist us in Luo's judicial investigation of the case, and was specifically responsible for the autopsy. Awesome! ”

Xie Zheng and their head catchers next to him all showed a look of amazement, and Patriarch Jin and Mrs. Jin were even more round-eyed with admiration. Of course, most of these looks are flattering exaggerations.

Lu Jinping smiled and said, "Now I want a room to test with the Dao method, and when I use the Dao method to test, no one can watch from the sidelines." ”

"Okay, I have a dressing room in the back room, I don't know if it's okay?" Mrs. Jin said with a smile.

"I'll see."

Lu Jinping came to the inner room and checked it, this house was actually the bathroom used by Mrs. Jin for bathing. There was only a large wooden barrel and a few round stools. There is also a screen for dresses. The windows are all closed. He nodded and said, "It's just right for me." ”

Lu Jinping first said to Xiong Zhutou: "You immediately send someone to extract the palm prints of all the people who have been in and out of the inner house on the day of the crime." Write your name and send it to me! ”

In ancient China, there was a sense of individual identification of palm prints very early. It's just that the comparison of palm prints in ancient times is actually mainly a comparison of the size of palm prints, rather than a detailed comparison of fingerprints on the palms, and it is not fingerprint technology in the modern sense, but extracting palm prints has been a common practice in ancient times. Therefore, these people were not surprised by Lu Jinping's instructions to extract the palm print.

Xiong Zhutou hurriedly agreed and hurriedly arranged.

Lu Jinping asked Mrs. Jin to take a clean handkerchief, wrapped the box whole, carefully carried it into the dressing room, put it on the stool, and then took the forensic investigation box wrapped in green cloth from Ye Qingqing's hand and entered the locker room, and tied the door.

He opened the forensic investigation box, took out fluorescence-enhanced protective glasses and put them on, and then, taking out the ultraviolet laser forensic scanner, he began to scan the jewelry box.

Because ultraviolet light can cause damage to the cells in the fingerprint, if the DNA in the fingerprint needs to be detected in the next step, it is possible that the cells in the very small amount of body fluid contained in the fingerprint can be damaged due to ultraviolet irradiation, and the DNA test will fail. He didn't know if there would be a need for testing later, so he had to minimize the damage to his fingerprints from ultraviolet light.

Therefore, he prayed that the fingerprints would be found as soon as possible. Fortunately, he soon found several clear fingerprints on the box. Taking a closer look, there are a total of four fingerprints available for detection.

Overjoyed, he immediately took out his digital camera from the box and loaded it with a UV macro lens and a bandpass filter. The ultraviolet light in your hand moves at a 45-degree angle to show your fingerprints, and after looking for the best angle, you take a few fingerprints one by one.

This ultraviolet laser imaging device is also the latest portable criminal investigation photographic imaging equipment, which can directly take pictures of fingerprints exposed by ultraviolet light and extract and fix. His forensic investigation box is used for field detection and examination, so it is also equipped with these commonly used portable forensic equipment.

He took out the digital camera memory card and inserted it into the microcomputer card reader in the forensic investigation box, and immediately, a clear fingerprint image was displayed on an LCD screen on the back of the case cover.

At this time, the bear catcher had already sent the palm prints of all the people who had entered and left the inner house. Because the catch brought this time is much faster, it is carried out separately, so the speed is very fast.

Lu Jinping took pictures one by one with a digital camera and then entered them into a microcomputer.

This microcomputer is equipped with the most advanced fingerprint retrieval and comparison system software, which can quickly and automatically retrieve tens of thousands of fingerprints to find the same fingerprint.

Because there are only dozens of fingerprints, it hardly took a second to freeze with a snap, and the fingerprints on the screen kept flashing, prompting that the same fingerprint was found.

But seeing that the name showed that it was Mrs. Jin herself, Lu Jinping shook his head. Her own jewelry box, of course, will have her fingerprints.

Then, another fingerprint was identified, and the identification result was also found to be the same, but it was Mrs. Jin's personal maid, and the third fingerprint was another personal maid's.

Only the last fingerprint remains.

When he entered the last fingerprint into the computer and compared it with the dozens of fingerprints extracted, he swept it over and showed that the same fingerprint was not found.

This comparison result made Lu Jinping happy, that is to say, a stranger's fingerprint appeared on Mrs. Jin's gold bracelet box, this person is sure that he is not from the inner house, then it is likely to be a thief.

Lu Jinping came out quietly and ordered the Jin Patriarch to extract all the palm prints of the servants of the outer house. At the same time, as much as possible, the fingerprints of the guests and villagers who came to or stayed in the Jinjia Mansion that day were also collected as much as possible. Some people who have already returned from a long distance cannot be extracted for the time being, so they can only check the fingerprints of those who can be extracted first.

The extracted fingerprints were continuously handed over to Lu Jinping, and every time he got a stack, he went in to scan it and compare it.

Suddenly, the picture snapped and froze, prompting that the same fingerprint had been found.

Lu Jinping looked at the name, it was an old woman in the kitchen in the front yard, Mrs. Qian.

Lu Jinping smiled, packed up his things and came out. Tell Mrs. Jin and Patriarch Jin to find this Qian Po, and at the same time, send a few trustworthy personal maids to his residence to search.

After the Qian Po came, she knelt on the ground with a nervous expression. Lu Jinping said: "Let me ask you, Mrs. Jin's bracelet is missing, do you know?" ”

The little eyes of the Qian woman rolled for a moment, and said, "You know, didn't the lady who was rich in gold steal it?" The lord and wife have already locked her in the firewood room and are ready to send her to the official. ”

"Bastard!" Patriarch Jin was annoyed and embarrassed, and interrupted her sharply. Because the news has not yet spread, the people in the village still don't know that Jin Dafu's wife is the sister of the baron of Kaiguo County, and the previously broken lord has turned over at the moment.

Qian Po was reprimanded a little inexplicably, because everyone in Zhuangzi said this and knew about it, so why can't they say it now.

Lu Jinping said: "Then let me ask you, where were you on the day Mrs. Jin's bracelet was stolen?" ”

Mrs. Qian looked nervous and said, "I, I am helping in the kitchen in the front yard, there were many guests that day, I was busy, and many daughters-in-law and girls in the village came to help." ”

"Have you ever been in the inner house?"

Qian Po's slightly rickety body trembled obviously, and quickly shook her head and said, "No, I haven't come in." ”

Lu Jinping sneered and said, "You really haven't come in?" I'll call the porter to confront you, and they'll see it if you come in, and I'll have two porters that day, and I'm going to ask each of them, and I'll be able to ask them." Are you going to make me struggle or are you confessing yourself? ”

Lu Jinping has already locked that this Qian Po should be the one who stole the gold bracelet, and she doesn't look like a person with martial arts, so it is unlikely that she will sneak in through the wall. If you want to enter the inner house, you must enter through the courtyard gate. The concierge was added that day, and there should be an impression.

Sure enough, as soon as these words came out, Qian Po suddenly broke out in a cold sweat on her forehead, thought about it, and said, "I remembered, I came in." At that time, ** milk was entertaining guests in the front yard, and after being busy, a coat on her body was a little hot, so she took it off, and I just came over with food, so she asked me to help her send the coat back before putting it in the house, don't get dirty. So I took the garment and went into the inner house, put it in the bedroom, and went out and did nothing else. ”

The second aunt of the Jin patriarch, who was following Master Jin, nodded and said, "There is such a thing, I asked her to take it back." ”

Lu Jinping looked at Mrs. Qian and said, "Are you really sure that you only went to the house of the ** grandmother, and did not go to the old lady's room?" ”

Mrs. Qian shook her head and said, "I didn't go, I really didn't." ”

"Then have you ever entered the old lady's house before, and have you ever touched the lady's jewelry box?"

Mrs. Qian hurriedly shook her head and said: "No, we only work in the front yard, and we can't enter the inner house without the permission of the old lady, let alone touch the old lady's jewelry box, how can the old slave have that blessing?" ”

Lu Jinping said: "When I sent you just now, I already asked someone to search your house. Do you guess there will be a discovery? ”
