At 7:50 a.m. on June 11, Xuan Guang, vice president of the First People's Hospital of Nanshan City, walked into the 15-story hospital building, took the elevator, and went up to the 15th floor. This floor is the office area of the hospital, the offices of the president, vice president, and secretary of the party committee, and the offices of the party and government departments of the hospital.

Xuanguang knocked on the door of Dean Li Chuansheng's office. The dean was on duty last night, and he came to take over. According to the routine, the two of them had to carry out the handover of the leaders of the hospital, and then Dean Li went home to rest.

But there was a few knocks on the door, but there was no response from inside. Vice President Xuan twisted the doorknob, and the door opened. He saw Dean Li sitting crookedly in a leather swivel chair behind the large desk, with his upper body leaning on the desk. He was a little strange, it was already 8 o'clock, could it be that the dean was still asleep? He walked to the desk and called again: "Dean Li, it's time to get off work!" ”

But Dean Li still did not respond. Xuanguang felt that something was wrong, he walked up to Dean Li and touched Dean Li's hand, which was cold. Touching his neck again, it was cold. When I touched my body again, it was already stiff. He, he's dead! Xuanguang is also a doctor, he turned to look at the face of Dean Li who was facing away from him, his face was blue and his convulsions were very hideous, and the blood flowing from the corner of his mouth had coagulated. He immediately felt that Dean Li had died of poisoning. He hurriedly picked up his mobile phone and called 110 to call the police.

After receiving the report, the criminal police of the Criminal Police Brigade of the Municipal Public Security Bureau immediately rushed to the First People's Hospital of the city.

The team leader, Tian Chunda, has rich experience in solving cases, and he looked at Dean Li's face and said to team member Hao Dong: "I think it was poisoning and death." ”

Hao Dong nodded in agreement. They knew that an autopsy would have to be done in the final decision. Whether it was suicide or homicide must also be determined through investigation.

Hao Dong, a young criminal policeman, found that there was leftover coffee in the porcelain cup on the desk, and he carefully put away the cup while wearing gloves and prepared to take it for testing.

Tian Chunda found a one-yuan coin under the leather swivel chair. He also wore gloves and carefully put them away for testing.

The next day the autopsy report came out. Li Chuansheng was arsenic. Frost poisoned him, and the time of death was roughly between 0:00 and 1:00 a.m. on June 11. Arsenic was found in the coffee residue found in the porcelain cup on his office desk. Frost residue. On the one-yuan coin found, a male fingerprint was detected, and after comparison and identification, it was confirmed that the fingerprint was the fingerprint of Chang Xiaowei, deputy director of the Department of Internal Medicine.

The criminal police began to talk to the relevant personnel to investigate and understand the case.

Team leader Tian Chunda and young criminal policeman Hao Dong talk with Xuan Guang, vice president of the hospital, in his office.

"Vice Dean Xuan, when is the last cleaning time in Dean Li's office?" Tian Chunda asked.

"The dean's office is cleaned by the cleaner in the morning. If the dean is on duty at night, he will also be cleaned by a sweeper before he leaves work during the day. ”

"Dean Li, has there been any anomaly recently?"

Xuanguang thought for a moment and said, "I didn't find it." ”

"Is there anything unusual in the hospital lately?"

"Didn't find it, everything is fine lately."

"Does Dean Li have any enemies and people with particularly big contradictions?"

"I didn't notice that either. There are thousands of people in the hospital, and there must be contradictions, but I didn't find anyone who had a particularly big contradiction with President Li. No enemy was found. ”

"Who can get to the dean's office when he's on the night shift?"

"This, generally speaking, cadres above the middle level can come to him if they have something. Sometimes, general medical staff and staff can also come to him if they have urgent matters or major matters. ”

"So, there are a lot of people who come in and out of his office at night?"

"Yes. But after midnight, there were very few people who came looking for him. Because the dean can take a break after midnight. At this time, there were very few people who came to him. ”

"Who in the hospital came to Dean Li's office on the evening of June 10?"

"This still needs to be investigated."

Then, Tian Chunda and Hao Dong talked to Xu Zaishan, the cleaner who cleaned the dean's office.

"Master Xu, did you clean Dean Li's office before you got off work during the day on June 10?" Tian Chunda asked.

Xu Zaishan nodded, "Yes." The dean was on the night shift that night, so I went to clean the dean's office at half past four in the evening. ”

"Did you find anything on the floor while cleaning?"

Xu Zaishan thought for a while and said, "I carefully swept the floor and wiped the floor, but I didn't find anything on the ground except for a little dust." ”

"Didn't you find a single dollar coin?"

"Nope. I swept it so carefully that not a single hair could fall. How can a one-dollar coin not be seen? ”

After talking to Xu Zaishan, Tian Chunda whispered to Hao Dong: "Master Xu cleaned Dean Li's office before the day shift and didn't find a coin, so this coin appeared in Dean Li's office during the night shift." The fingerprints on the coin belonged to Chang Xiaowei, deputy director of the Department of Internal Medicine, so he should have arrived at Dean Li's office during the night shift. We'll talk to him right away. ”

Hao Dong said: "Okay. ”

The two came to the office of Chang Xiaowei, deputy director of the Department of Internal Medicine. They saw Chang Xiaowei nearly forty years old, with very bright eyes, fair skin, medium height, and a well-proportioned body. He was slightly surprised to see the police come to talk to him, but immediately enthusiastically gave up his seat and poured water for them.

Tian Chunda expressed his gratitude and began to ask: "Deputy Director Chang, are you also on the night shift on the evening of June 10?" ”

"Yes."

"Have you ever been to Dean Li's office during the night shift?"

"Nope. I didn't go. ”

"If you think about it, haven't you been?" Tian Chunda asked.

Chang Xiaowei still shook his head: "I haven't been there." ”

"But we found a one-yuan coin under the swivel chair in Dean Li's office, which should have been dropped during the night shift, and there was only your fingerprint on it."

"Coins? A dollar coin? I hadn't been to Dean Li's office that night, so how could a coin be thrown in his office? ”

"We're going to ask you, what's going on?"

Chang Xiaowei thought for a while and said, "There are two possibilities, one is that I went to Dean Li's office during the day and fell off at that time." Also, it was left behind by someone else during the night shift. ”

Sweeper Xu Zaishan carefully cleaned Dean Li's office before the end of the day shift and found no coins on the ground. The coin must have been dropped during the night shift. Tian Chunda stared at Chang Xiaowei's face and said.

"That's someone else dropped."

"But the fingerprints on the coin are yours."

Chang Xiaowei thought for a while and said: "My coat is hung on the wall of my office, and there are many people who come and go in my office every day, so it is easy to take out coins from my pocket." Then I threw it in Dean Li's office at night and planted it for me. ”

Tian Chunda thought that the reason he said could also be valid. He asked, "You said that someone might frame you, but who could that person be?" ”

Chang Xiaowei thought for a while and said, "I still have to think about it." ”

After breaking up with the police, Chang Xiaowei looked at the list of internal medicine staff pressed under the desk and thought: This person here is most likely to frame me. But she has a beautiful face and a very weak personality, can she do something to kill Dean Li and frame me? Say not necessarily. Besides, I can't tell the police about my suspicions about her.
