The next morning, the warm sunlight spread on the streets of City A, waking up the sleeping city.

Qiu Lan, who was asleep, slowly opened her eyes, washed and changed her clothes, sorted out all her things, and left Qingshuiwan and drove to the police station.

Unexpectedly, as soon as I walked into the criminal investigation building, I met Xu Chengyan in the elevator.

Maybe it was because she knew about Qi Mo's pregnancy, so Qiu Lan obviously had a strange feeling in her heart when she saw him.

"Doctor Qiu, it's early. Xu Chengyan pursed his thin lips lightly and nodded slightly,

"Officer Xu is early. Qiu Lan involuntarily moved her eyebrows and responded simply.

After that, the two didn't say anything, just silenced each other, until they were in the elevator, Qiu Lan suddenly remembered the case and asked a few words about the case in a low voice.

"Officer Xu, how is the serial murder case before, is there any progress?"

"Well, I found some information yesterday. Xu Chengyan nodded, raised his hand to look at the time on his wrist, and said in a low voice, "Wait until nine o'clock, in the office of the serious crime team, we will have a meeting with Expert Cao, and I will inform him." ”

"Good. Qiu Lan nodded in response, then left the elevator and returned to the office.

At nine o'clock in the morning, there was a low-pressure atmosphere in the office of the serious crime team, and Xu Chengyan printed the recent materials into paper documents and handed them to the two people in front of him.

"Doctor Qiu, Specialist Cao, based on the information you provided, we have re-investigated the people in the bar, especially the regular customers of the bar and the waiters in it. Xu Chengyan lowered his eyes and roughly scanned the documents in his hand, with a solemn expression.

"Among these people, we found a very suspicious person. He paused and found one of the pieces of information from the document, "This person's name is Huang Weisheng, a waiter in the private room on the second floor of the bar, and his background is very special. ”

Qiu Lan, who had a serious expression, took a serious look at the information in his hand and said indifferently, "His brother is an addict and died because of drug abuse, which is quite in line with our previous inference, the murderer is a person who hates drugs very much, and also hates drug users and drug sellers. ”

"Dr. Cho is right. Xu Chengyan nodded in agreement, his voice was flat, "And not only that, we also learned that this person once reported drug trafficking in the bar, but the colleagues in the anti-narcotics department at that time did not find drugs, but later this person also quarreled with Qiao Peiqin." ”

"Looks suspicious. Qiu Lan's eyes sank, with a hint of chill in her eyes, "Officer Xu, have you asked him to come back to investigate?

"No, we didn't scare the snake for the time being. Xu Chengyan shook his head and moved his eyebrows thoughtfully, "The information we know is provided by the waiters in the bar, there is no substantive evidence, I have discussed it with Zhigao and them, and I still want to find evidence before we do it." ”

Listening to his words, Qiu Lan pursed her red lips, and the expression on her face stiffened a little.

Judging from the previous two crime scenes, the murderer was a very thoughtful person, who did things in an orderly manner, and left almost no clues at the crime scene, in this case, finding evidence became a problem.

Suddenly, a bold idea came out of Qiu Lan's mind.

"Officer Xu, if that person is really the murderer, there is a way for him to show his fox tail. ”

"What way?" Xu Chengyan raised his eyebrows, looked at the person in front of him suspiciously, and asked in a low voice.

"Find someone to pretend to be a rich second generation who is addicted to drugs to go to the bar and lure the snake out of the hole. A few numbers, concise and to the point, Qiu Lan pursed her red lips, her eyebrows and eyes were deep.

"It's a solution, but how do we find the right person to convince the suspect? And it's too dangerous to risk finding a crowd. Xu Chengyan turned the pen in his hand and thought silently.

Cao Fan, who was sitting on the side, also lowered his eyes and thought about this question calmly, but Qiu Lan already had a predetermined candidate in her heart.

"Officer Xu, isn't the most suitable person right in front of you?"

Needless to say, this person is her.

"I've been to that bar before, and I'm still haunting Qiao Peiqin's private room, those waiters at that time should all remember me, and if I appear again, it shouldn't arouse the vigilance of the suspect, and I'm also a police officer, and it's my duty to arrest the murderer. Qiu Lan looked at the two people in front of her, her eyes were firm, and she didn't mean to waver at all.

However, Xu Chengyan was a little worried in his heart, the last time it was already very risky, he didn't want her to be on a risk, and in his eyes, Qiu Lan was a forensic doctor, and he had no power to restrain the chicken, how could he be alone in the tiger's den?

"Doctor Qiu, forget it, I'll apply for my superiors to find a female police officer to do this, if something happens to you, I can't be responsible. Xu Chengyan pursed his thin lips and rejected her proposal.

"It's still me, Officer Xu, this matter is very important, the murderer is a very cautious person, once you startle the snake, it will be even more difficult, I appeared in front of those waiters, I do this, it is much better than a stranger. Qiu Lan, who had a serious face, said righteously, without a trace of fear and timidity.

After listening to their conversation, Cao Fan on the side nodded meaningfully and opened his lips indifferently, "Officer Xu, in fact, I agree with Dr. Qiu's statement, don't look at our Dr. Qiu as studying medicine, but she is smart and in danger, maybe she will really be better than an ordinary female police officer." ”

Their words made Xu Chengyan shake a little, he never wanted Qiu Lan to be in danger.

Qiu Lan saw his careful thoughts, coughed lightly twice, and pretended to be relaxed and teased: "Officer Xu, are you not confident in you or am you not confident in me? Are you absolutely bad at your protective measures? Or do you think I can't handle that suspect?"

"No, of course not. Xu Chengyan shook his head and glanced at her softly.

In the previous case, he had already seen her skills, and there was no doubt about her ability, but this matter was not trivial, it was a psychopathic serial murderer, once there was a little mistake, it was very likely that something would go wrong, but if the murderer was not arrested as soon as possible, the lives of others would be in danger.

After weighing it again, Xu Chengyan nodded, "Doctor Qiu, I will ask my superiors for instructions, don't worry, I will do my best to protect your safety." ”

As soon as the words fell, there was a sudden sound of hurried footsteps outside the office, and then, Pei Pei ran to the door panting, knocked lightly on the door, looked panicked, and hurriedly spoke.

"Doctor Qiu, Chief, Specialist Cao, it's good that you are all here, our colleague just received a call from the police, and a villager found a woman's body in the Houshan District to the west. ”
