Forensic pursuit

Nie Fanxin stayed at the research institute to wait for the results, while Chen Anyou, who was on duty, and Chu Wanning went back to the police station across the street.

Near eleven o'clock in the evening, the detention center with its closed gate suddenly opened, and the last room on the second floor, the policeman shouted into it: "Hu Hua, come out."

A few seconds later, the stubble-faced man walked out of the room tremblingly, stretched out his hands consciously, and the police handcuffed him.

After a criminal suspect is transferred to a detention center for custody, investigators shall interrogate him in the detention center.So when Hu Hua entered the interrogation room, Chu Wanning and Nie Fanxin were already sitting behind the wooden table opposite his chair.

Chu Wanning spoke concisely and asked straight to the point: "Hu Hua, December 12th, where are you after 26pm?"

The man drooped his head, stared at the concrete floor under his feet, his eyes were blank: "At home."

Chu Wanning looked serious: "Who can prove it?"

Hu Hua raised her head slightly: "There is no proof, I am at home alone."

Chu Wanning took the photo: "This Toyota car with the plate number Jiang BZU723, did you lend it to anyone else on the night of the incident?" Then he changed another one, "Look at this zoomed-in picture again, the person wearing glasses is you?"

Nie Fanxin handed over one photo after another, and one question after another came out of Chu Wanning's mouth.Hu Hua first bit her lip and said nothing, then said, "I remember, I went to a massage parlor on Basho Street at about 11:[-] that night."

The woman followed closely and asked, "Which store?"

"I forgot my name, you can look it up yourself." At this time, Hu Hua was a different person when he begged them to take him away two days ago. He didn't cooperate, or talked about him.

Chu Wanning was patient enough to grind with him, holding a photo in a sealed bag: "Why is there Lu Zhenglin's hair in your trunk?"

Hu Hua's voice was low and steady, but the corners of her mouth trembled twice: "Okay, good friend, I accidentally got his hair on my clothes and put them in the trunk, isn't that normal?"

Chu Wanning asked: "What about the sebum secretion?"

Hu Hua majored in biochemistry as an undergraduate. Although he was engaged in education and training, he lost his knowledge for a few years, but he still knew the most basic things.For example, DNA cannot be detected in sebum secretions, so he replied at a moderate speed: "I was drunk two days ago, and I slept in the trunk by myself. Why? No?"

Being cunning, Nie Fanxin's grip increased, and the pen used for recording poked a few small holes in the paper. Without thinking, he asked, "Which day did you get drunk? Who did you drink with?"

The next second, she received Wan Yi's WeChat message, and the two coincided with each other: "Fanxin, ask him which day he got drunk?"

Hu Hua recalled: "On the day Lao Lu died, I came out of the massage shop and bought a bottle of white wine on the side of the road and drank it myself."

Chu Wanning's face was a little sullen: "Didn't you go home?"

"Wake up and go home, it's four or five in the morning."

Wan Yi's message came again: "You guys go to the massage parlor and take me with you."

Nie Fanxin: "Go home and rest. (Super vicious emoji package)"

"Helpful for investigation."

Nie Fanxin: (helpless emoticon package)

Wan Yi: "Good."

Chu Wanning took Nie Fanxin's detailed transcript, confirmed it with the suspect according to the procedure, and after signing it, the police from the detention center took Hu Hua back, and the three drove to Bajiao Street.

In the dead of night, Nie Fan, who was sitting in the back row, felt drowsy and dozed off with her eyes closed. Wan Yi beside her suddenly said, "Sister Wan Ning, send two more people to Hu Hua's house."

Chu Wanning was puzzled: "Why?"

Under Wan Yi's calm face, her thin lips parted slightly: "Does he use essential oil for massage, or what kind of essential oil does he use?"

Chu Wanning looked ahead, and looked back from the front-view mirror from the corner of her eye: "Do you know the reason for this?"

"Sebum secretions in the trunk contain ylang-ylang oil."

"Okay." Chu Wanning informed Lao Yang and transferred two colleagues who lived nearby.

The lights on the side of the road went out one after another, and the carriage became quiet. Nie Fanxin dozed off with her head up, slowly tilted to the left, and finally landed gently on Wan Yi's thin shoulders.In the darkness, Wan Yi lifted the thin blanket that Nie Fanxin had put on her lap, and gently covered her body.

The patrolling police near Bajiao Street had already locked down the massage shop. When they got out of the car, the police stepped forward and said, "Captain Chu, there is indeed a person named Hu Hua who went to their shop for a massage on the night of the incident."

Chu Wanning thanked: "Thank you for your hard work, take us up."

Weixin Massage Room is located on the second floor of an old house in the third section of Bajiao Street. It is not included in the scope of demolition. Because the price is reasonable, it attracts customers from several nearby streets.

Moderately decorated massage room with complete security facilities, one monitor outside the door and one monitor at the cash register inside the house.Chu Wanning was negotiating with the proprietress, Wan Yi began to look around, and her eyes fell on the essential oil cabinet next to the bed.

She then asked, "Boss, do you use ylang-ylang oil for massage here?"

The proprietress replied: "I used it a few years ago, but there were many customers with allergies, so I didn't buy it."

Wan Yi then asked, "What essential oil did Hu Hua use that night?"

"I'll look it up." The use of essential oils in the massage room will be recorded. The proprietress turned on the computer to browse, and then said, "Geranium."

Wan Yi thanked her, and Chu Wanning took the mouse from the proprietress' hand and checked the monitor.At 23:47 on the night of the incident, Hu Hua knocked on the door of the massage shop.The massage parlor was closed, but the proprietress still received him.

Wan Yi, who was staring at the monitor, suddenly reminded: "Sister Wan Ning, click to pause." She zoomed in on the picture captured by the monitor, and found red lumps and bumps on the back of Hu Hua's hands and wrists, and blurted out, "He is allergic. Wan Ning Sister, inform Hu Hua's family colleagues to find this suit."

At 1 o'clock in the morning, Wan Tong turned over and got out of bed, listening to the steady breathing at the pillow.She walked lightly and slowly, walked into the bathroom on the first floor, looked at Wan Yi's number, hesitated for a moment, and finally dialed Nie Fanxin.

"Fanxin, when will you go home, how is Xiaoyu?"

Nie Fan tilted her head, glanced at the woman wearing a white coat and holding a reagent tube, and said in a low voice, "Sister followed me back to the police station, we are now in the research institute."

"Have you eaten tonight? Are you still feeling uncomfortable?"

Nie Fan didn't want to disturb Wan Yi, so she walked to the side and replied: "Eat, she has probably recovered, she looks energetic."

"Your aunt refused to sleep, and fell asleep when she couldn't hold on."

"Lao Wan, let's go to bed too. There is a new development in Lu Zhenglin's case. We must be going home very late."

Nie Fanxin listened to Wan Tong's advice, hung up the phone, turned around, and saw Wan Yi's lips curled up: "Fanxin, Hu Hua's inner shirt is stained with geranium, and her jacket is covered with ylang-ylang oil."

"In other words, Hu Hua is lying. I just received news from Sister Wan Ning that there is a 24-hour convenience store next to Hu Hua's parking lot. The convenience store surveillance saw him sleeping in the driver's cab, not the trunk."

Wan Yi nodded, and Nie Fan waited for her to pack up the equipment on the laboratory table, took off her white coat and hung it up, and said immediately: "Let's go."

"where to?"

"go home."

Wan Yi: "What about you?"

Nie Fanxin helped her turn off the light: "Send you off on the way, and then go to work."

"I……"

Nie Fanxin interrupted what she wanted to say: "No, your body can't stay up late."

Wan Yi bent her lips: "Okay, then trouble the driver."

Nie Fanxin grumbled: "Who let you inherit your aunt's road blindness, luckily it's not that serious."

"Driving one less car, saving fuel and environmental protection."

"Yes, yes, what you say makes sense."

The two jokingly went from the upstairs of the research institute to the parking place in the compound. After getting in the car, Wan Yi was probably tired and soon fell into a deep sleep.

Seeing the lights at home turned on, Nie Fanxin stepped on the accelerator and drove towards the detention center.She arrived 2 minutes later than Chu Wanning. Hu Hua had already been taken out of the cell, and her hands were handcuffed on the chair frame in the interrogation room.

Chu Wanning stood outside the interrogation room, her slender figure reflected in the one-sided glass, and Nie Fanxin approached from behind her.Gazing deeply into the room, he asked for a moment, "How is it?"

Chu Wanning raised her right hand lightly, holding her chin: "It hasn't started yet." She turned sideways, cast a little shadow, and covered Nie Fanxin under it, "Observe first."
