Wang Shen immediately turned on his computer and logged into his email. Soon after, an email arrived. Wang Shen first opened the medical records of the driver's daughter. The doctor at the hospital must have known the police needed this data, so he had neatly written "leukemia" in large, regular script on the records. Wang Shen felt a pang of sympathy for the driver. Indeed, a strong father deserves everyone's sympathy. Wang Shen scrolled through the data; the next records showed the bank account transactions between the driver and Sang. There weren't any major issues; the driver's data showed normal transactions, with no suspicious large transactions. Wang Shen continued scrolling.

Actually, Wang Shen was more interested in Sang's bank account transactions. If someone deliberately told Sang about Zheng Wu's murder of Han Shuang and demanded that Sang accuse Zheng Wu, then Sang must have received a benefit from that person. In any case, Wang Shen didn't believe Sang would push Zheng Wu into such a predicament without expecting anything in return. No, it wasn't that simple. Sang's transaction records for the past year showed that none of her accounts had received any funds exceeding normal amounts. Of course, there was another possibility: cash transactions. To confirm this possibility, they would have to wait until that evening to conduct an on-site investigation at Sang's workplace.

Suddenly, Wang Shen stopped scrolling the mouse in front of a string of data. Besides his sharp mind, a large part of Wang Shen's ability to solve many criminal cases also stemmed from his extraordinary memory. Wang Shen stared at one of Sang's expenditures. 1500? The last few digits of the remittance account seemed vaguely familiar. Wang Shen immediately swiped the mouse in the opposite direction, returning to the pages about the hit-and-run driver. He slowed his mouse movements, and after about half an hour, he stopped at a data point related to the hit-and-run driver.

Wang Shen noted down the last four digits of the driver's and the remitter's accounts, as well as the time and amount of the payment. The amount matched perfectly at a glance: 1500. To ensure accuracy, Wang Shen moved the data to Sang's page. He compared the two account last four digits and the remittance time and discovered a startling clue. The driver and Sang had actually made a 1500 transaction a month prior. What was the purpose of this transaction? How were they connected? Could this event have been the direct trigger for the traffic accident? The answer lies with the survivor.

Wang Shen called Captain Li again and learned that the driver was still at the traffic police brigade, so he drove there. Unlike the criminal investigation brigade, the traffic police brigade didn't have a dedicated interrogation room, so all questioning had to be conducted in a relatively quiet office. Captain Li had suggested sending the driver to Wang Shen, but Wang Shen refused. After all, before all the clues were clear, Wang Shen didn't want to treat the driver as a suspect.

Before Wang Shen entered the office, the driver who caused the accident was already sitting in a chair. Wang Shen and the driver exchanged a glance. The past half-day seemed to have aged the driver considerably.

“I’ve come to see you today because there are some things I want to ask you about.” Wang Shen took out a cigarette from his pocket, handed it to the driver who caused the accident, and lit it for him. “I hope you can answer my questions honestly, otherwise, you may not be able to clear your name in this traffic accident.”

“I said I would tell you everything truthfully. Just let me leave quickly, my daughter is waiting for me at home. She will cry if she sees that I haven’t come back for so long.” The driver took the cigarette out of his mouth, speaking with pleading, and agreed to Wang Shen’s request.

"Did you know the deceased's name was Sang?"

The driver who caused the accident shook his head.

"After the accident, did you see what the deceased looked like?"

The driver who caused the accident shook his head again.

"You hit someone with your car, didn't you immediately get out and check on the person you hit?" Wang Shen couldn't understand the driver's behavior.

“When we arrived, he was still sitting in the car. He seemed terrified,” Captain Li whispered to Wang Shen, standing next to him.

"This is the person. Take a look. Do you remember him?" After hearing what Captain Li said, Wang Shen nodded, took out Sang's photo from his pocket, and pushed it in front of the driver who caused the accident.

"Huh? This person? I know him."
