Bai Gao and Peng Xiaoyan are both vice presidents of Nanjiang Company, and the relationship between the two turned out to be incompatible, and recently the general manager wanted to return home, and the relationship between the two became dead and alive.
That day, Bai Gao saw a Weibo on the Internet, saying that shrimp contain a large concentration of pentapotassium arsenic compounds, and if taken at the same time as vitamin C, it will be transformed into toxic tripotassium arsenic, which is commonly known as arsenic! Remembering that Peng Xiaoyan often invited him to eat shrimp recently, and brought him fruits with high vitamin C content such as oranges after eating, Bai Gao couldn’t help but be afraid. It seems that Peng Xiaoyan is going to kill him!
Bai Gao decided to fight back, he read a large number of domestic and foreign detective suspense novels and stories, and finally, the crime idea finally came up for him.
On May 5, Bai Gao was going to Qingdao on a business trip, and on this day, Bai Gao booked a ticket to fly to Qingdao at 8 o’clock in the evening and quietly went to Peng Xiaoyan’s dormitory.
Peng Xiaoyan saw that Bai Gao was coming, and specially made him braised abalone and opened a bottle of red wine. Looking at Peng Xiaoyan’s flushed face, Bai Gao almost softened. However, the thought of her going to kill herself, Bai Gao’s heart hardened again.
After the meal, Peng Xiaoyan wanted to send Bai Gao out, and just as he was about to open the door, Bai Gao suddenly returned the horse gun and inserted a scalpel into Peng Xiaoyan’s heart with his gloved hand.
After killing Peng Xiaoyan, Bai Gao carefully took out a cigarette box from his pocket and opened it, and inside were two cigarette butts. Peng Xiaoyan has a classmate named Yan Xiaoyan, who is the vice mayor, and the two of them usually have a close relationship. Bai Gao had previously found an opportunity to pick up the cigarette butt that Yan Xiaoyan had lost, put the cigarette butt into the ashtray, and found Peng Xiaoyan’s mobile phone and the door key and put them in his pocket, before closing the door and leaving.
Getting into a taxi, Bai Gao looked at his watch, and at 7 o’clock sharp, it was a maximum of 30 minutes from Peng Xiaoyan’s house to the airport.
Before boarding, Bai Gao took out his mobile phone and looked at the time, 7:33, so he sent a text message to Peng Xiaoyan’s mobile phone, saying that he would send a text message to report to her after he arrived in Qingdao. After a while, he used Peng Xiaoyan’s mobile phone to send a text message back to his mobile phone, saying to pay attention to safety. Then he turned off both mobile phones and boarded the plane to Qingdao with the flow of people.
When he arrived in Qingdao, Bai Gaoyi opened his mobile phone and found that both mobile phones had received service text messages from mobile companies. He never read this kind of text message, and deleted it all casually.
Bai Gao hurriedly reported to the hotel, put down his luggage, changed into a trench coat, put on a hat and sunglasses, packed a car, and quickly returned to Nanjiang City.
When he arrived in Nanjiang City, it was already 4 o’clock in the morning, Bai Gao got off at the gate of a community not far from Peng Xiaoyan’s dormitory, asked the driver to wait, and he walked quickly to Peng Xiaoyan’s dormitory. He used Peng Xiaoyan’s door key to open the door, and after entering the door, put Peng Xiaoyan’s mobile phone and key into Peng Xiaoyan’s bag. After doing this, he returned to Qingdao City with the car.
Two days later, Bai Gao received a call from the boss, asking Peng Xiaoyan why she had not gone to work in the past few days, Bai Gao said that he was in Qingdao for a meeting, did not know the situation in the bureau, and he had not contacted Peng Xiaoyan for two days, hoping that the director would send someone to her house to take a look.
That evening, Bai Gao received a call from the Nanjiang City Public Security Bureau, saying that Peng Xiaoyan had been killed at home, and hoped that Bai Gao would return home as soon as possible to assist the police in the investigation.
The criminal police captain of the Nanjiang City Public Security Bureau, a master’s degree student in his thirties, named Cui Minqin, listened to Bai Gao’s explanation of the situation in Peng Xiaoyan’s dormitory that day, and then read the text message received by Bai Gao’s mobile phone from Peng Xiaoyan’s mobile phone. The text message was sent at 7:33 p.m. on the day Peng Xiaoyan was killed, which proves that Peng Xiaoyan was still alive at that time; At 8 o’clock, Bai Gao got on the plane to Qingdao, and it took half an hour to get from Bai Gao’s house to the airport at the earliest, so Bai Gao had a clear alibi.
Because Bai Gao’s suspicion of murder was ruled out, Cui Minqin’s attitude towards him was naturally polite, he told Bai Gao that Peng Xiaoyan’s death time was between 5 p.m. and 7 p.m. on May 5, asking Bai Gaozhi if he didn’t know who Peng Xiaoyan had an appointment with at that time period? Bai Gao shook his head blankly.
Cui Minqin asked again: “In the days before May 5th, did Peng Xiaoyan’s classmate Yan Xiaoyan visit her home?” ”
Bai Gao said: “I don’t know. ”
“So how often is the ashtray in Peng Xiaoyan’s dormitory cleaned?”
Finally asked the point, Bai Gao was overjoyed, he deliberately thought for a while, and then said: “I heard Peng Xiaoyan say that she cleans the room every night before going to bed, and she has a cleanliness problem.” ”
Cui Minqin nodded and left.
The cigarette butts found in the ashtray of Peng Xiaoyan’s house contained the saliva of Peng Xiaoyan’s classmate Yan Xiaoyan. Moreover, Yan Xiaoyan’s fingerprints were also found on the doorbell of Peng Xiaoyan’s dormitory. As a result, the criminal police quickly discovered Peng Xiaoyan’s improper dealings with Vice Mayor Yan Xiaoyan. At this point, the facts of the case seem to be obvious, this is a love murder case.
Soon, Bai Gao “turned positive”, and when the boss was in a meeting, Cui Minqin suddenly arrived with two criminal policemen, saying that Peng Xiaoyan’s case had made a new discovery, and they wanted to hear Bai Gao’s opinion.
When he arrived at the general manager’s office, Cui Minqin took out a few pieces of printing paper from his briefcase and said: “In line with the attitude of being responsible for the suspect, we went to the mobile company to call up the detailed list of all the contents of Peng Xiaoyan’s text messages in the past few months, and found an amazing secret!” It turned out that Peng Xiaoyan and Vice Mayor Yan Xiaoyan had been plotting to include you in the list of cadres aiding Xinjiang. ”
After Cui Minqin finished speaking, he handed the detailed list of the text message content in his right hand to Bai Gao’s eyes and said: “What surprised me even more above was this text message that we once ignored, at 10:25 p.m. on May 5, Qingdao Mobile sent a service text message to Peng Xiaoyan!” At this time, Cui Minqin raised his head and looked at Bai Gao’s eyes and said, “This is a service text message sent by Qingdao Mobile to customers entering the market, that is, this mobile phone visited Qingdao City at 10:25 pm on May 5.” Strange, how did Peng Xiaoyan’s mobile phone appear in Qingdao, Mr. Bai, how do you explain? ”
Bai Gao’s usual smiling face in officialdom froze at once, saying in his heart that he was really too clever to calculate and miss Qing Qing’s life!
