Chapter 17 first quarter

Everyone dispersed. Qin Yang looked at Su Yu who was alone by the window, lost in thought. Just as he was about to speak, Su Yu suddenly turned around and said, "Captain Qin, do you want to say that there is a connection between the case of Song Zixin's mysterious falling from the building and the case of Ye Xuan?" The relationship is that someone is avenging Ye Xuan who died unjustly ten years ago?" Qin Yang was a little stunned: "Really, I can't hide anything from you, you even learned mind reading skills." Wang Gang smiled and said, "You kid was born in the present. If you were in ancient times, you would be burned to death as a god."

Su Yu shook her head in confusion: "Actually, ever since I figured out the truth about Michelle Ye's case, I've been thinking about it. Wei Pengfei and Song Zixin haven't been in touch for ten years, yet they both ran to Michelle Ye's cemetery at the same time. It was no accident that I went to pay her respects. Three months later, Song Zixin died strangely. The way of death and the weather at that time were exactly the same as the night of Ye Xuan's death. Three people, there was no one else at the scene at the time. Who would know the truth and hide it for ten years before avenging Michelle Ye?"

Wang Gang speculated: "Wei Pengfei, I think he is the most likely one. He probably wasn't telling the truth. When he ran up to the top of the building, he might have just seen Ye Xuan being pushed downstairs by Song Zixin. Years later, when he was short of money to buy drugs, he remembered it again. So he found Song Zixin's contact information and blackmailed her. Song Zixin had no choice but to pay him again and again. In the end, it was unbearable, and the two There was a dispute, and Wei simply poisoned Song Zixin to death with a toxin he got from somewhere." Qin Yang couldn't help interjecting: "But, don't forget, Wei Pengfei has an alibi witness, that rabbit. Besides, Song Zixin only called him 50,000 yuan in total, which is a drop in the bucket for Song. She wouldn't take the risk of turning against Wei Pengfei just for this little money. She could spend money to find someone in the underworld to settle Wei Pengfei's peace. Anyway, after such a long time, Wei couldn't produce any actual evidence to prove that she had killed someone."

He turned to Su Yu and asked, "Su Yu, tell me your judgment. Is Song Zixin's death related to the Ye Xuan case? Or is it just a separate case?" Su Yu hesitated for a moment, and said: "Qin team, I'm really not sure about this question. My intuition tells me that there must be a close connection between the two, but it's true that Wei Pengfei, the only insider at the moment, has a very clear disagreement. Evidence at the scene. What's even more strange is that the toxin found in Song Zixin's body is said to be strictly controlled in the United States. How could it appear in our small Jiangcheng? I suggest that we do the following things first : First, let Wei Pengfei accept the polygraph as soon as possible. Second, find out the source of the toxin and find out its composition. This may require the help of experts from the Provincial Public Security Bureau. Third, collect information on Song Zixin's falling from the building through the media in Jiangcheng. Clues, especially the employees of the Crown Hotel, nearby residents, and passers-by on the day of the incident, what they may have seen and heard. No matter how small the clues are, they must be collected. These may be the key to solving the case. The last point, investigation Take a look at Professor Ye's medical records to find out if he really suffers from Parkinson's disease."

Wang Gang was startled: "What, you don't suspect Professor Ye, do you?" Su Yu said seriously: "All related persons are objects of suspicion. This is the principle. Professor Ye is the most motivated person to avenge Ye Xuan. Have you ever seen a person who is less like a murderer than Song Zixin? Human nature is the most unpredictable Yes. Especially in the face of greed and hatred, many people are unable to control themselves, and finally embarked on a road of no return." Qin Yang nodded approvingly: "Well said, look at the endless criminal cases now, if there aren't so many people who take risks, we criminal police can have a good rest, and we don't have to be so busy all day that we don't even have time to shave our beards."

Wang Gang stretched out his head and looked: "Captain Qin, you look handsome even without shaving, Su Yu, right?" As he spoke, he winked at Su Yu. Su Yu couldn't help but also smiled: "Of course, our Qin team is the most handsome guy in the criminal police team." "Go, go, go, stop flattering the two of you, everyone has worked hard to solve the case of Michelle Ye falling from the building this time. I will report to the director and try to organize a day trip or something. Relax, come back and make persistent efforts, take The case of Song Zixin." "Ah, it's only a day trip." Wang Gang immediately grimaced.

"Not bad, you boy, you are not satisfied yet." The three of them were talking and laughing, when He Li hurriedly pushed the door in: "Su Yu, hurry up and chase after Zi Yan, she left, crying so much that I can't even stop her." Su Yu's heart sank. Wang Gang sighed: "The elder sister who has been dependent on each other since childhood is a murderer, and no one can accept it all at once." Qin Yang quickly waved his hands and said, "Su Yu, let's go." Su Yu rushed out of the criminal police office building in one breath.The streets are full of people and traffic, where did she go?

"Zi Yan, answer the phone, answer the phone quickly!" Su Yu anxiously dialed the phone while trotting along the side of the road. The late autumn rain, wrapped in wisps of cold air, floated on Su Yu's hair and collar, but he didn't feel the cold at all, because a blazing flame was burning in his heart. Suddenly, a lonely figure flashed in front of his eyes, leaning against a blue Mazda. "Zi Yan—" he shouted across the street. Song Ziyan turned around slowly, and under the blue floral umbrella was a face full of tears. "Su Yu—" she choked up and called softly.

Su Yu stared at her deeply, curled the corners of his mouth, showing an infinitely warm smile.
