After listening to Qiu Lan's analysis, Xu Chengyan pulled the siren above the police car and returned to the police station as quickly as possible.

In the science and technology testing room of the Criminal Investigation Building, the inspector called up the clip of the restaurant on the night of the crime.

Sure enough, it was exactly the same as Qiu Lan guessed.

The male deceased, Shu Qiming, not only did not take his mobile phone with him when he left, but the surveillance also clearly recorded the footage of Huang Lishan opening his mobile phone.

However, at that time, the people of the serious crime team did not think that the murderer was likely to be the injured, so they did not pay attention to this action.

Unexpectedly, they ignored this important place.

"Officer Xu, now we can be sure that Huang Lishan has a motive for killing. Qiu Lan glanced back at Xu Chengyan, her eyes were meaningful.

Killing people for love is a conclusive motive.

With a motive, it can also be confirmed that there is an element of lie in the confession of the female victim.

Her suspicions are getting bigger and bigger, and the case is gradually getting closer to the truth.

"Dr. Cho, we can now believe that the female victim was the murderer of the male deceased, but we still lack evidence. Xu Chengyan lowered his eyes thoughtfully, his face heavy.

Only the blood stains and fingerprints of the injured and the deceased were found at the scene of the crime, and Huang Lishan admitted that she had been to the scene of the crime and was injured.

Just when the case was at an impasse, the phone call that Qiu Lan answered became the most critical point.

"Hey, Doctor Qiu, I'm Cao Fan, I just re-examined the evidence and found a suspicious point, which was related to the murder knife at the scene. ”

Five minutes later, in the identification room of the Criminal Investigation Building, there was the bloodstained murder weapon on the smooth tabletop, and Qiu Lan and the people from the Serious Crime Team and the Forensic Identification Department were standing next to it.

"When we first inspected the knife, we only determined that it was the murder weapon, and because the knife was very common in the market and had no directionality, we put it aside for the time being. ”

Cao Fan slowly picked up the evidence bag of the murder knife on the other side of the device, and methodically stated the information about it in his mouth.

"But because Dr. Qiu later mentioned the situation of the female injured person, we had to review the evidence, but we didn't expect to find a substance in the place where the folding knife was most likely to hide dirt and dirt. ”

He paused, handed the information in his hand to a few people in front of him, and then made a final decision, "It's perfume." ”

"Perfume?" Pei Pei furrowed his brows suspiciously, and asked in a low voice, "Isn't it normal that the murder knife has injured Huang Lishan and has been stained with perfume?"

"It's not normal. Qiu Lan stared at the ingredient list in her hand solemnly, and shook her head slightly to deny her words.

"The place where the perfume was found was the gap in the folding knife, and when the blade irritated the female wounded woman's body, this gap had no chance to touch her body. Qiu Lan's eyes sank, and she analyzed unhurriedly: "And I remember, here, we haven't even found blood, let alone perfume." ”

"The only possibility is to lift the perfume at other times. ”

The voice settled, and Qiu Lan dropped her slender fingers on the ingredient column again, "There are also the ingredients of this perfume, the first few items are ordinary ingredients, but the Hu Mu fragrance in this one is very different." ”

"I remember that there was a new brand on the market that was the first to add this ingredient, but they haven't had a launch ceremony yet, that is, they can't buy it on the market, and only internal employees can access it. ”

Suddenly, a bright light appeared in Qiu Lan's deep eyes, she was stunned for two seconds, and then said indifferently, "Officer Xu, do you remember the profession of the female wounded?"

"Koryta's sales representative, it just so happens that this perfume is this brand, which means that it is entirely possible for her to get into this perfume. ”

"The knife belonged to the female deceased. Qiu Lan and Xu Chengyan almost unanimously came to this conclusion.

The murder weapon was the female wounded, but according to her confession, the male deceased died in front of her, so how could this knife arrive at the scene of the crime in advance?

There is only one truth, that is, the murderer is the female injured person.

The case suddenly became clear, and all the mysteries were solved.

"Pei Pei, Xiao Tiao, there is enough evidence, immediately apply for a search warrant and an arrest warrant, and we will arrest the suspect Huang Lishan. Xu Chengyan pursed his thin lips, and his deep words were loud.

"Yes!" The two men standing behind him immediately responded, then turned and left the forensic section.

The truth of the homicide case was finally revealed, and a heavy burden was laid down in everyone's hearts.

"Doctor Qiu, thanks to you this time, if you hadn't found the flaw in the female wounded, I'm afraid we would still be in the maze and didn't come out now. Xu Chengyan hooked the corners of his lips at Qiu Lan, and his sunny smile was full of praise.

"It's not just me, it's everyone's. Qiu Lan responded softly, but what she thought about was Li Shanghan's figure.

This case is actually thanks to him, it was he who woke her up from a different angle.

So she still doesn't grab this credit.

Inadvertently, the corners of Qiu Lan's mouth couldn't help but outline a perfect arc, and the sweet smile was particularly moving.

"Look how happy our Dr. Qiu is smiling, I don't know if the case was solved, maybe I think she thought of her sweetheart?" Cao Fan raised his eyebrows and whispered a joke.

Listening to his words, Qiu Lan narrowed the corners of her mouth and lowered her eyes slightly, "Expert Cao, did you say that I laughed stupidly?"

"Not stupid, not stupid, Doctor Qiu is the smartest of us here, if you are stupid, what should we do?" Officer Xu, did you say?" Cao Fan glanced at the person next to him with a smile and said a few amusing words.

"Yes, Dr. Cho is very smart. Xu Chengyan nodded lightly, and a different emotion flashed in his eyes.

At this moment, Qiu Lan felt a vibration on the side of her clothes.

When she took out her phone, it was exactly the person she was thinking about now.

"Hey, what's wrong?" Qiu Lan pursed her red lips and said softly.

The voice settled, and a familiar voice quietly sounded, "I'm in the Ben Hotel now, there is something to do here, if it's convenient for you, come over now." ”

Ben Hotel?

Qiu Lan's brows instantly twisted involuntarily.

That was the place where she arranged for Qi Mo's father to work, and it was very likely that something happened there that was the business of Qi Wen's family.

But how could it be that Li Shanghan called to tell her?

didn't have time to think about it, Qiu Lan hurriedly explained to Xu Chengyan and left with her bag on her back.

When she got off the bus in front of the Ben Hotel, she saw the crowd of onlookers from a distance, and the noise rose and fell.

What's going on?

She trotted all the way over, struggling through the bustling crowd, and Li Shanghan's figure instantly fell into her eyes.

But next to him, there were two other people.

One is a man with a head full of blood and a big belly, and the other is Qi Mo's father, Qi Wen's family.
