Lies
There were three chairs in the monitoring room, each occupied by a witness. No one was talking and everyone's face looked gloomy. I exchanged a glance with Xu Jianglun, neither of us understanding what Gao Cheng was looking at with such great interest. Suddenly, Gao Cheng asked, "Have your studies reached a conclusion?"
He gradually got used to his mind jumping, so he immediately reacted that he was inquiring about the car thing we discussed earlier Qin Ya Li. Having a precedent, Xu Jianglun hinted at me to speak.
I had to force myself to speak up: "It's not impossible for Qin Yali to raise 50,000 yuan in such a short period of time, but it's not a continuous repayment, but rather a one-time settlement. The source of this money may be problematic."
"It goes without saying, Wu Yan gave the money, let's talk about something else."
He was taken aback for a moment, then found his voice: "How did you know the money was given by Wu Yan?" Gao Cheng looked down at me, "The motive to lie."
I found myself unable to keep up with his rhythm, "What's the motive for telling lies?"
He was speechless: "Where did you wander off to just now? Standing with me watching the entire interrogation process, and yet you didn't notice that the three witnesses were lying?"
"Ah?" The voice of surprise wasn't mine, but Xu Jianglun's beside me. After catching Gao Cheng's sidelong glance, he stuttered and asked: "Gao sir, why did you say... that all three witnesses are lying?"
A few seconds of silence, I thought Gao Cheng would ignore him again, but he said with a proud expression: "To determine whether someone is lying or not, you can observe their body language and gestures. When Qin Ya Li was making the record, she answered almost every question without hesitation." I felt it wasn't right and raised an objection: "She had already made a record before, those questions should have been asked, it's normal for her to answer immediately this time."
But Gao Cheng shook his head, "Wrong! She looked down slightly when answering, not daring to make eye contact with our detectives. This is a sign of guilt. Moreover, even if it's the same question, at different times, the answers can't be exactly the same without any difference."
I immediately reacted: "Have you read her record before?"
"Haven't you seen it too?"
Suddenly, I remembered the stack of materials that were asked to be looked at yesterday in the early morning. The last few pages seemed to be some witnesses' testimony. Because I had read two pages and felt roughly similar, I didn't look carefully. Turning my head to look at Xu Jianglun, he immediately understood and handed over the materials in his hand, and also whispered: "I just compared them, and they are indeed exactly the same."
As Gao Cheng said, no one can answer two records with exactly the same words. This situation usually has only one possibility, that is, this answer was memorized in advance, and Qin Yali was very nervous when answering the police's questions.
I read her statement word by word and then looked for the other two. After finishing, I raised my head: "Ma Tao's statement is consistent with the interrogation just now, Du Xiangyuan has no record, where can you see that they are also lying?"
Gao Cheng's expression became even more bland, but this time he didn't beat around the bush and went straight to the point: "They say that a person's eyes are the windows to their soul, reflecting their mental state. Ma Tao, due to his professional training, answered very smoothly, seemingly without any flaws, but he definitely didn't expect that his overly calm gaze would give him away."
I thought about it and understood what he meant. Ma Tao was interrogated twice, making it clear that the police were focusing on him, and ordinary people would be anxious, tense and uneasy, but Ma Tao was very calm during the interrogation.
