Chapter 810 (1/2)
Officer Liu is an old police officer sent by the provincial department and the leader of the special task force. He has understood what Long Fei means. If the fingerprints on niutouqin are not only Qian Wanqiang's and an Meimei's, but also those of other people within 40 days, it means that an Meimei is lying! Even if she didn't switch the piano, she must have let others touch it!
However, there is a problem. With the police's current technology, it is impossible to accurately determine the exact time of fingerprints left on erhu!
For example, the police can detect a person's fingerprint on it, but they can't accurately judge when the fingerprint was printed. The longer the time, the more unable to judge!
In this way, Long Fei's idea can not be realized at all! Because the police are likely to judge the fingerprints of 40 days ago as those of 40 days later! Forty days ago, of course, many people came into contact with Niutou erhu.
Police officer Liu just wanted to tell Long Fei that his idea is unrealistic. At present, their technical strength can't reach this level, but he found that although Long Fei was talking to him, his eyes glanced at an Meimei beside him! But an Meimei's eyes glanced at her intentionally or unintentionally, and her face was a little nervous, as if she was very concerned about her answer!
Police officer Liu is also a human being with rich experience in handling cases. He immediately understood what Long Fei meant. Perhaps Long Fei also knows that the police don't have such high technology. His only purpose is to test an Meimei!
If what an Meimei said was a lie, she would be very nervous when she heard that the police had such technology! Because this technology can easily expose her lies. And an Meimei is obviously a daughter who can't hide things in her heart. Her psychological activities will be shown on her face!
These psychological activities just flashed away in officer Liu's mind. He immediately said, ”of course, it's very simple for modern technology to identify the specific time when fingerprints are left on objects. As long as we take this piano back, we can tell who moved it in 40 days, except Qian Wanqiang and miss an! ”
In order to be more similar, officer Liu confirmed to Qian Wanqiang again: ”Qian Wanqiang, are you sure that since you put the piano here, no one has touched it except you and miss an?”
”I'm sure! I was going to take out my things after brother Zhou's pawn deadline. ” Qian Wanqiang said.
”That's good. In that case, if we judge through fingerprint detection that there are other people who have touched the piano in the past 40 days, then the piano will be suspected of being switched! At that time, miss an will have to give us an explanation! I hope miss an will cooperate with us in the investigation
When officer Liu speaks, his eyes look at an Meimei, and Long Fei's eyes also look at an Meimei!
Although an Meimei tried her best to cover up the confusion in her heart, they both saw the abnormality on her face. Long Fei could even feel the confusion in her heart!
”There's something wrong with an Meimei! Even if she didn't switch the bullhead erhu, she must have let other people touch it! I've got to figure out what he knows! ” Long Fei thought of it in his heart.
Long Fei wants to find out the secret in an Meimei's heart immediately, but he is with the police after all. It's not appropriate for him to ask many questions, and he can't do anything to an Meimei now. I have to talk to the beautiful miss Ann some other time.
Niutouqin had been taken. Although it was a fake, it was useless for people to stay, so they went back to their home.
On their way back, instead of being a police car, police officer Liu and Li Ping got into Longfei's Mercedes Benz.
”Team Liu, it seems that we don't have the kind of technology you told Dr. long?” Li Ping asked.
”Not really.” Officer Liu replied with a smile.
”But you just said there was? And a serious look? ” Li Ping doubts a way.
Officer Liu and Long Fei looked at each other, and then officer Liu said, ”if not, how do you know if an Meimei has lied?”
Although Li Ping still didn't understand the key, she didn't ask in detail. She just asked, ”even if we know that an Meimei lied, what's the matter? We have no evidence to take her back to assist in the investigation. ”
”We don't have a way, but I think Dr. long has a way. Right, Dr. long? ”
Police officer Liu was sent by the provincial department and knew more about Long Fei than Li Ping. He knows that the reason why the provincial department will pay direct attention to this case is because of Long Fei! The purpose is to help Longfei find the real Tauren! Although the police due to the rules and regulations, some things can not be done, but Long Fei no such scruples!
”What can Dr. long do?” Li Ping asked.
”Oh, is your mother better?” Long Fei directly changes the topic. He doesn't want Li Ping to know how to deal with an Meimei.
”Well, I won't ask. Since taking Dr. Long's medicine, my mother has been much better. ” Li Ping said.
”Chinese medicine alone can relieve your mother's pain and prolong her life, but it can't make her recover. Therefore, I hope you can send her to Longcheng hospital as soon as possible.” Long Fei said.
