    Chapter 67: Majoring in Applied Psychology? Identifying the Hidden Killer!

    Su Ming’s words caused Qu Wenbiao, who had been silently bowing his head, to suddenly raise it. His eyes trembled slightly, as though he was struggling to maintain his composure.

    He opened his mouth but remained silent for quite a while before finally forcing out a hoarse and trembling voice.

    “I… I don’t know what you’re talking about.”

    “What transfer? I haven’t made any transfers to anyone.”

    “Other than being the murderer of this case, I don’t know anything else.”

    It was evident that, even though Qu Wenbiao was part of a very small group of university students from the previous century, his weak character and lack of wit caused him to react like other criminals in such a situation.

    He could only stubbornly deny knowledge of the situation, clinging to a pointless refusal to admit anything.

    But this case was extremely serious.

    It couldn’t be dismissed simply because Qu Wenbiao said a few words of ignorance.

    Lin Tian, who was sitting next to him, had no expectation that Qu Wenbiao would provide any answers. He turned to Su Ming and asked.

    “Xiao Ming.”

    “Are your sources accurate? Has Qu Wenbiao made any large transfers during this period?”

    Su Ming nodded, handed Lin Tian the phone on the table, and answered with certainty.

    “Yes, Director Lin.”

    “Before coming to the interrogation room, I roughly deduced that Principal Qu may be planning to take the fall for the crime himself.”

    “So.”

    “I believe the mastermind behind this may have been in contact with Principal Qu for a long time, and their relationship is probably not unfamiliar, meaning coercion is unlikely.”

    “Then, after analyzing the reasons and motives behind most people involved in drug trafficking…”

    “Although some might be driven by the thrill of it, I believe money is still the most likely reason.”

    “And as the principal of a private school, even if he isn’t a shareholder in the school’s founding, his financial capacity would still be far from weak.”

    “Since Principal Qu and the mastermind have such a relationship, and he may even be willing to take the fall for this murder, I conclude…”

    “Before joining the drug trafficking organization, he must have contacted Principal Qu for help. When there was no other option, he would have joined the organization.”

    “So checking the transfer records is the best way to validate my assumption.”

    “As for the final result…”

    “Director Lin, just as the text messages on the phone show, there are indeed large transfer records.”

    After listening to Su Ming’s reasoning, Lin Tian nodded in agreement, showing approval but not much surprise.

    As an experienced senior criminal investigator, Lin Tian believed he could have made the same deductions. He looked at the numerous transfer records on the phone and said in a calm voice.

    “Ah Sheng.”

    “What’s the relationship of Principal Qu’s family like? Does he have children studying or working abroad?”

    The seasoned detective quickly deduced from Su Ming’s earlier words, the transfer records on the phone, and Qu Wenbiao’s attitude and behavior, that Qu Wenbiao likely had a child studying or working in another country.

    Without hesitation, Xu Changsheng quickly nodded and replied.

    “Yes! Boss, yes.”

    “Principal Qu has a son studying in the United States, named Qu Pengfei, but we haven’t investigated it deeply yet.”

    “At the beginning of this case, we never expected it would involve so many people!”

    Lin Tian nodded thoughtfully.

    He carefully observed Qu Wenbiao’s expression and noticed he was obviously uneasy but trying not to show it. He kept clenching his fists and then loosening them, his knees tightly pressed together.

    These actions were enough to prove that Qu Wenbiao was in a state of extreme nervousness.

    From his earlier calmness to now being agitated and unable to suppress his anxiety, the dramatic shift in his emotional state made Lin Tian squint thoughtfully.

    He no longer tried to conceal his thoughts from Qu Wenbiao.

    Organizing his thoughts, Lin Tian used his experience to piece together the clues and said.

    “Ah Sheng.”

    “Check the internal database and gather some basic information on Qu Pengfei.”

    “If I’m not mistaken, the mastermind behind this case is likely Qu Pengfei, Principal Qu’s only son.”

    “From the large overseas transfers and Principal Qu being willing to take the fall for the murder, the only person who could be behind this is his son.”

    “Of course.”

    “As a father myself, I can roughly deduce the reason for that six million from the house sale being transferred and then sent back…”

    At this point, Lin Tian paused for a moment and fumbled in his pocket, seemingly wanting to light a cigarette. But then he suddenly remembered they were in the interrogation room.

    With a helpless sigh, he put his index finger, now yellowed from the smoke, to his nose and continued.

    “Principal Qu.”

    “If I’m not mistaken, your son must have gone to Las Vegas in the United States about three months ago?”

    “He probably lost a lot of money and is now in debt.”

    “Otherwise, I can’t think of any reason that would consume such a large amount. Eight million wasn’t enough, and you were desperate enough to sell your house.”

    “When you transferred that six million from the house sale, you must have been furious with your son, telling him never to gamble again.”

    “But your son, being stubborn, transferred the money back to you and then decided to join the drug trafficking organization.”

    “Initially, he probably thought he could pay off his debts with the huge profits from the drug trade, but little did he know…”

    “Once he joined, he fell into the abyss.”

    At this moment, Qu Wenbiao’s face grew even darker, his lips trembling with fear, and cold sweat began to appear on his forehead.

    This was a result of overwhelming internal pressure and panic, but he still managed to force a weak smile and said.

    “Director Lin, you must have misunderstood.”

    “I really… I really don’t know what you’re talking about.”

    “Moreover, Xiao Peng has always been abroad and never came back, how could he have done such a thing here?”

    Lin Tian paid no attention to his forced explanation and comfortably leaned back in his chair, tapping the table.

    “Xiao Ming.”

    “You must have other clues that can further prove this matter, right?”

    “Please help out and make sure Principal Qu stops struggling and cooperates with us.”

    Upon hearing Lin Tian’s words, Su Ming quickly recalled all the earlier clues and lightly tapped the table.

    “First.”

    “Through blood tests on the deceased, we found traces of opiates and drug residues.”

    “We’ve traced the source of the drugs, but we still don’t have specific leads on the opiates.”

    “Because according to our criminal investigation technology department’s careful checks, we found that in the past two months…”

    “Magic City has strict regulations on opiates, with every prescription and medicine collection being logged and uploaded for tracking.”

    “So the possibility of these opiates coming from the hospitals in Magic City is very low.”

    “Whether they come from outside the province or from pharmaceutical production, we still don’t know.”

    “But now that we have an initial suspect, we can roughly judge that these opiates must have been brought back by Qu Pengfei from the United States.”

    “Compared to our country, opiates are in a state of abuse in the United States, and it’s not hard to get hundreds or even thousands of pills.”

    “But bringing so many drugs through customs is impossible, and to reduce his own suspicion…”

    “Qu Pengfei most likely flew from the United States to Myanmar or Cambodia and then sneaked back into the country.”

    “For a drug trafficking organization, human smuggling is an easy task.”

    “And since he brought opiates back, it shows that he chose to commit the crime at that point.”

    “That’s why Principal Qu had to dismiss the psychologist two months ago and replace them with yourself to conveniently find victims.”

    “And one more crucial point…”

    At this point, Su Ming looked at Qu Wenbiao’s trembling eyes and continued with a sharp tone.

    “That is, the ‘Skinny dog’ heard the eye exercise broadcast during the call. As a long-time school principal, I don’t think Principal Qu could forget the time for the eye exercise that happens twice a day.”

    “Only your son, Qu Pengfei, who had been abroad for so long, wouldn’t even subconsciously think about something like eye exercises.”

    “After all.”

    “The United States doesn’t have something like eye exercises, am I right, Principal Qu?”

    At this moment, Qu Wenbiao was completely panicked and stunned, his mouth opened but no words came out.

    In all these years, not even the day his wife was about to give birth had caused him this much panic.

    Just then, Xu Changsheng, who had been searching the database, suddenly slammed the table, excitedly saying.

    “I found it!”

    “Qu Pengfei majored in…”

    “Applied Psychology!!!”
