"Excuse me, sir, according to the law, you are obliged to cooperate with the police in the execution of their official duties. Xu Chengyan stared at the person in front of him indifferently and seriously, his lips moved slightly, "Xiaotiao, take him to the car, let's go to his house to have a look." ”

"Yes. Xiao Tiao nodded, walked to Li Gang's side, and grabbed his wrist, "Sir, please cooperate." ”

The man pursed his lips uneasily, fine sweat appeared on his forehead, and his eyes were full of trepidation, "I, I, but me." ”

Without waiting for him to say anything more, Xiao Tiao pulled him in the direction of the police car, and the other people followed in the car, ready to go to the suspect's home to check.

The cause of death of the female deceased Xiaocao was drowning in fresh water, and the suspect's home is the most suspicious place of the crime.

Police cars sped along the city's main thoroughfares, sirens blaring silently.

In one of the cars, Xu Chengyan drove the car, Pei Pei sat in the co-pilot, and Qiu Lan and Xiao Cong sat in the back.

"Doctor Qiu. The playful Pei Pei pursed his lips, looked sideways slightly, and looked at the person behind him with interest, "You were so godlike just now, that pier is so far away, people can't see clearly, how are you sure that person is Li Gang?"

"It's actually quite simple. Qiu Lan raised the corners of her mouth and sketched a sweet smile, "The age of the suspect Li Gang is already fifty years old, and the appearance described by the security guard is when he was in his forties. ”

"It stands to reason that it is difficult for an adult to change his body shape after the age of forty, just like the security uncle said, that person looks very iconic, and the body shape is also, about one hundred and sixty-five centimeters tall, but the weight is about one hundred and fifteen. ”

"And the person in charge of the management office said that Li Gang had just completed the resignation procedures, and I happened to notice the mark of a large suitcase at the door of the office, and since Li Gang was leaving, it was likely that he left it. ”

Qiu Lan, who had a calm face, gently twitched her red lips and methodically narrated a series of tight logic in her head, and the other three people in the car were dumbfounded.

"Not only that, but we also need to know that Li Gang is a boatman and is very familiar with the lines on the sea, if he really wants to go, it is very likely that he will choose to take a boat, and it just so happened that I saw this figure at that pier. ”

Qiu Lan tilted her head, her shoulders shrugged slightly, and her voice was brisk, "The similarity is so high, how can I not suspect that that person is the person we are looking for?"

An unbelievable reasoning made Pei Pei's mouth open involuntarily, and his eyes were full of admiration, "Doctor Qiu, you will be my goddess in the future, you are beautiful and capable." ”

"Yes, Dr. Qiu, I'll have to learn from you in the future. Xiao Cong nodded in agreement and praised repeatedly.

"I agree with that. Xu Chengyan hooked the corners of his lips, his gaze swept to the rearview mirror, and his gaze was firmly fixed on Qiu Lan's cheek, "Doctor Qiu is actually quite good at interrogation and criminal investigation. ”

"Peipei, we all have to study hard, otherwise we may be robbed of our jobs by Dr. Qiu one day. He chuckled under his breath, his voice brisk.

"Don't praise me, I'm just a professional habit, and I'm very careful about everything, so I can detect a lot of subtle things. Qiu Lan pursed her red lips lightly, her eyes lowered.

Not long after chatting, the convoy of police cars stopped at the entrance of an alley, which is a flat building area, and the alleyway is narrow, and vehicles cannot drive in.

Everyone got out of the car and walked in, and in front of a red house, they stopped.

Li Gang, who looked panicked, tightened the corners of his lips, his hands kept trembling, and finally took out the key to the door and dropped it on the ground twice.

Qiu Lan's group of people standing behind him silently paid attention to his movements.

Walking into the room, there was a mess inside, the wardrobe door was wide open, dirty clothes were left outside, the sofa was a mess, and the floor was full of garbage and takeout boxes.

"Officer, this, this is my home, there is really nothing to see, and it can't be related to any case, you believe me, I really have something. Li Gang swallowed his saliva and looked at the person in front of him in a hurry, his fingers trembling slightly.

"Sir, whether it matters or not, we will naturally find evidence to prove it. Xu Chengyan pursed his thin lips lightly and responded in a low voice, without a little wave on his face.

"Expert Cao, Doctor Qiu, the scene will be handed over to you. ”

"Good. Qiu Lan and Cao Fan nodded in unison, strode into the room, and began to search for things related to the case.

From a cursory glance, this room is only about twenty square meters, and it is unobstructed, but the sundries are piled up randomly, and it is also difficult to search, and there are many small traces on the body of the female deceased, so Qiu Lan can't let go of a little clue.

Perhaps something found on a small object could be the key piece of evidence.

At this moment, Mo Heng, who was standing in front of the wardrobe, glanced back at Xu Chengyan behind him with a solemn expression, "Officer Xu." ”

She picked up a light pink piece of women's underwear and whispered, "This is not something that will appear in the home of a single man." ”

As soon as he saw that the searchers had found these things, the short and fat man immediately couldn't sit still, his feet kept moving back, and his body was tense.

"Mr. Li, can you explain this?" Xu Chengyan pointed to the underwear and stared back at the man with a heavy face.

"This, isn't this normal?" Li Gang lowered his eyes, his gaze kept scanning the ground, and the sweat on his forehead slipped down one by one, "I'm a normal man, take a woman home, is it illegal?"

"Not breaking the law. Qiu Lan walked over with small steps, the lines on her face were slightly cold, "However, according to a normal woman's thinking analysis, this style and model of underwear should be worn by a little girl." ”

She raised her eyes, her sharp and deep gaze as if she wanted to see through the short and fat man directly, "According to my country's juvenile protection law, if you have a relationship with a minor that should not have happened, you will also be judged. ”

"This, isn't this with minors, it's just a kind of fun?" Li Gang pursed his lips uneasily, and his explanation was slightly pale and weak.

In the following time, Qiu Lan and Xiao Cong also found a lot of items related to the ante-mortem injuries on the body of the female deceased, and the people in the forensic department found a lot of female products or things related to girls.

Although these questions have been prevaricated by Li Gang with the reason of taking the woman home, the final answer will not be known until the police station identifies it, but looking at the current form, Li Gang's suspicion will only increase.

"Mr. Li, I'm sorry, I think I need to ask you to go back to the police station and sit down. ”

Half an hour later, Qiu Lan and his party returned to the police station, Xu Chengyan took the suspect to the interrogation room of the criminal investigation building, while the others returned to the laboratory with evidence.

People lie, so the mystery is revealed by silent witnesses.
