Yu Chihong's eyes froze, and Qiao Yan hurriedly winked at him and smiled. "I won't say anything, let's go quickly,

"The consequences of offending me are serious, you better be careful." After Wei Chihong finished speaking lightly, he started the car leisurely.

The car was quiet for a while, Qiao Yan remembered what happened to Ye Julie, hesitated to tell Yu Chihong, and finally decided not to say it yet. "I don't know how the case went." She seemed to be talking to herself.

Wei Chihong asked: "Do you mean Yin Xinyue's suicide, or Feng Yanze's murder?" ”

"I think the two cases may be related, but I can't think of where the connection point is for the time being." Qiao Yan had something vague in her mind, but she couldn't grasp it, "Can you find the source of the potassium cyanide capsule that Yin Xinyue used for suicide?" ”

"Investigating." Wei Chihong had already considered this problem, and he also suspected that Yin Xinyue did not commit suicide, "There is a fine powder left in the bottle containing potassium cyanide capsules, and after Cao Chongshan has been tested, it was confirmed that it was a sleeping pill, that is, the bottle was originally filled with sleeping pills. This sleeping pill is a prescription drug, and it is strictly monitored by the State Food and Drug Administration, and it can only be purchased with a doctor's prescription. But Yin Xinyue did not have insomnia symptoms, nor did she go to the hospital to prescribe medicine, it is likely that someone inside the hospital got it. ”

"It's suspicious to tear off the label, because I'm afraid of tracing the source of the drug." Qiao Yan pondered, "If Yin Xinyue asked someone to get sleeping pills from the hospital and wanted to commit suicide, why should he take potassium cyanide again." ”

Wei Chihong nodded in agreement. "I think the biggest possibility is that the person who gave sleeping pills to Yin Xinyue mixed potassium cyanide capsules and sleeping pills."

Could it be that Yin Xinyue originally just wanted to take sleeping pills, but she was poisoned by potassium cyanide capsules? But what's the matter with the suicide note? Qiao Yan was puzzled.

"It's impossible to judge right now." Mr. Wei said that an investigation was underway into Ms. Yin's neighborhood to see if anyone was working in the hospital, that people in the hospital could get sleeping pills, that there were laboratories in large hospitals, and that there was a possibility that they had access to potassium cyanide capsules. ”

Hospital? Qiao Yan's heart "chuckled", and Xiaoqing's words suddenly sounded in her ears. Jing Junbai said that Feng Yan recently hooked up with a nurse...... I don't know if I'm interested in that nurse, and it's normal for them to enjoy a woman together with their virtues......"

If Ye Julie and Jing Junbai also have an improper relationship...... She shuddered, not daring to think about it.

But seconds later, a plan formed in her mind. "Cao Chongshan's wife, what hospital does she work in?"

"At the first hospital in the city." Wei Chihong asked sensitively, "Why did you suddenly ask about this?" ”

"It's nothing, just now when I talked about Cao Chongshan's test powder, I remembered that his baby wife was here." Qiao Yan replied casually, "In what department?" ”

A vague smile appeared on Yu Chihong's lips. "You'll have a place for her in the future."

"What do you mean?" Qiao Yan was a little confused.

"She's in obstetrics and gynecology." Wei Chihong's tone was light, but Qiao Yan clearly heard the ambiguous meaning.

Qiao Yan's face turned red, why was she in such a department, so what could she do with her plan? After thinking about it, it must still be implemented, so I simply put my heart sideways and let it out cheekily!

After returning to the Public Security Bureau, Qiao Yan wanted to ask Cao Chongshan for a phone, but suddenly remembered that Zhong Kai also worked in the First Hospital, so she asked Wan Xing for help and inquired from him about Ye Julie's working hours. Zhong Kai was also refreshed, although he was in surgery and didn't know the nurses in the obstetrics and gynecology department at all, he still learned through his relationship that Ye Julie had work in the afternoon.

Qiao Yan went directly to the hospital and pretended to meet Julie Ye by chance.

"Qiao Yan," Ye Julie greeted Qiao Yan warmly, "why did you get here?" ”

"I ......" Qiao Yan was a little embarrassed.

"Oh-" Julie Ye immediately looked clear, "Is there one?" ”

"Not sure yet...... Just suspicious...... So come to the hospital for a check-up. Qiao Yan was struggling.

"What's so embarrassing about that, it's a good thing." Ye Julie looked at her with a smile, "Why didn't Lord Wei Chi accompany you, he is not too young, he must want this child very much." ”

"He's so busy, where is he free." Qiao Yan smiled reluctantly, she wanted to tell her not to tell Cao Chongshan about this, but after thinking about it, with the relationship between Cao Chongshan and Wei Chihong, it seemed unreasonable to hide it from him, but it was suspicious, so she gave up.

Julie Ye gently grabbed her waist. "I'll take you there, so you don't have to wait in line."

She was so enthusiastic, which made Qiao Yan feel a little guilty, how embarrassed she would be if she suspected the wrong person. When passing by the bathroom on the left side of the corridor, Qiao Yan acted according to the plan, told Ye Julie that she was going to the toilet, and handed over the bag and the thermos cup in her hand to her for safekeeping.

In that thermos cup, Qiao Yan specially wiped the original fingerprints clean, and then put on gloves before touching the thermos cup to prevent her fingerprints from being left.

After entering the bathroom, Qiao Yan took out her mobile phone from her pocket and called Wanxing.

After returning to Ye Julie, Qiao Yan received a call from Wan Xing, saying that there was an urgent matter in the bureau and asked her to go back quickly. She had to apologize and say to Julie Ye that she had a temporary task and had to rush back, so she could only come back another day.

Ye Julie sighed and said: "Your job is really good, you can't even accommodate private matters, then call me in advance next time, and I will contact you all." ”

Qiao Yan thanked her and left in a hurry, and after walking out of the hospital building, she sighed, obviously she was here to perform an important task, why did she feel a little guilty?

After returning to the Public Security Bureau, Qiao Yan handed over the thermos cup to Wan Xing, and she was responsible for asking Cao Chongshan to have his fingerprints checked.

Wan Xing arrived at the forensic science and technology laboratory, handed the thermos cup to Cao Chongshan, and asked him to compare whether the fingerprints on it were consistent with a certain fingerprint on the medicine bottle used by Yin Xinyue to commit suicide.

Without saying a word, Cao Chongshan began to collect fingerprints.

After a while, Yu Chihong and Lu Bin walked in together, they wanted to know if there were any new discoveries in Cao Chongshan.

Cao Chongshan was not calm when he saw Yu Chihong. "Lord Yu Chihong, congratulations."

Yu Chihong was confused. "Where does the joy come from?"

"Your little Joe, do you have it?" Cao Chongshan smiled, "She went to the hospital for a pregnancy test at noon and was bumped into by Lily." Because there is an urgent matter to rush back to the bureau, it has not been tested, but it will be made another appointment. ”

"Why didn't Qiao Yan go until noon, and the news came." Wan Xing was quite surprised, "Cao Curly Mao, are you keeping in touch with your family Lily around the clock?" ”

Cao Chongshan is happy. "I often have to call her to send her my care and love."

Wan Xing's heart was sour, but he didn't dare to reveal anything.

"It's a great event." Lu Bin joined in the fun, "It seems that I will have to change my voice to Qiao Yan 'sister-in-law' in the future." ”

Yu Chihong was very calm, he knew that Qiao Yan was not pregnant at all. His safety measures have always been very good, even if there is an accident, Qiao Yan's menstrual vacation has only ended recently, and it is impossible to know that she is pregnant so soon. It's just that he didn't understand which one Qiao Yan was singing, and he was even more suspicious when he thought of her suddenly asking which hospital and department Ye Julie was in in the morning.

"I'm not sure if I'm pregnant, so don't talk too soon." Wan Xing hurriedly interrupted, "Cao Curly Mao, you hurry up and compare the fingerprints, don't grind." ”

Cao Chongshan snorted, but still started to do business.

Yu Chihong looked at Wanxing suspiciously. "What fingerprints are compared?"

Wan Xing winked at him, put his finger to his lips, and made a booing motion.

Lu Bin also saw the gesture, so neither he nor Yu Chihong made a sound.

Cao Chongshan collected fingerprints and compared them. As a result, the fingerprints on the thermos cup were the same as those of one of the people left on the medicine bottle.

"Whose fingerprints are these?" Cao Chongshan expressed curiosity.

"I don't know, I'm just here to run errands." Wanxing took back the thermos cup and ran away.

Before leaving the laboratory, Wei Chihong solemnly warned Cao Chongshan and Lu Bin that the news of Qiao Yan's visit to the hospital was not allowed to be spread.

After Zeng Jinling and Qiao Yan learned the results of the fingerprint comparison, they both fell into silence, and Wan Xing also sighed.

Wei Chihong walked into the office of the special investigation team and saw the expressions of the three people, and knew that this matter was not trivial. "What's the matter with fingerprints?"

Zeng Jinling and Wan Xing both looked at Qiao Yan, so Qiao Yan pulled over a chair for him to sit down and said to him one by one.

Yu Chihong's face was gloomy, and he held the armrests of the chair tightly with both hands, holding them so hard that the green tendons on the back of his hands were exposed.

"I can't tell Cao Chongshan about this for the time being." Qiao Yan saw him like that, and was very worried that he would go to Cao Chongshan now and tell him everything. Although he and Cao Chongshan get along with each other in a more unusual way, Qiao Yan can feel that they are actually good buddies with deep feelings.

"I know what to do." Yu Chihong didn't have the impulse that Qiao Yan imagined, he stood up, straightened his back, held his head high, and his body was straight, like a statue. After a long time, he finally took a deep breath, barely suppressing his anger, "First go to the First Hospital to investigate the source of potassium cyanide." ”

Yu Chihong immediately set off with Qiao Yan to the First Hospital. They learned that the hospital has a laboratory, but the use of potassium cyanide must be approved, and then it must be registered and signed, and the use and dosage must have strict management requirements, and two people must check, sign, and hand over shifts, and it is impossible for people outside the laboratory to have access to potassium cyanide. Then the problem can only be within the laboratory.
