Luan Ping already knew about Zhang Jun's arrest, but neither Chen Yan nor Li Hong asked him to stop the investigation, so Luan Ping naturally wanted to complete the task.

"Jia Xinyi went home after get off work yesterday afternoon. The school surveillance and community surveillance have video evidence."

Luan Ping also checked the video surveillance of the previous month: "Jia Xinyi's work and rest schedule is relatively regular. For some time, he has been painting in the studio every Thursday and Friday, and he has been at home the rest of the time."

Chen Yan and others nodded, which was consistent with the findings of Wang Gang's return.

"This Liu Jingting is a bit special."

"What's so special?" Li Hong asked with a frown.

Luan Ping played a video: "This is a video from 10:50 last night. Qin Xiaoyu came from the dormitory to the teaching building at 10:30, and then came out."

"Captain, Captain Chen, look!" Luan Ping pointed to the blurry figure in the video: "One of these two people is the deceased Qin Xiaoyu, and the other is Liu Jingting. The direction they left is exactly the direction of the teaching building construction site!"

The second shoe print!

Chen Yan immediately thought of the shoe prints on the second floor!

At present, the context of the entire case has gradually become clear in Chen Yan's mind.

Although he couldn't pinpoint the murderer, Chen Yan had a hunch that he was not far from the truth.

"Luan Ping, arrest Liu Jingting and Jia Xinyi immediately!"

"Wang Gang, check the WeChat account under Jia Xinyi's name and the WeChat account registered under Qin Xiaoyu's roommate's name to see if someone has given Qin Xiaoyu another WeChat account to use."

"Also, track down the BMW driver who picks up Qin Xiaoyu every Tuesday, check his WeChat account and chat records with Qin Xiaoyu!"

snort!

Who stipulates that one person can only use one WeChat account?

Especially for female students in art schools, if they only have one WeChat ID, wouldn’t they all be exposed?

"Finally...Zhao Bing, arrange to check Zhang Jun's...private parts, focusing on whether there are any scratches!"

Ga?

Li Hong and others looked at Chen Yan strangely. Everyone knew about the other arrangements, but what about checking Zhang Jun's... private parts?

There was nothing embarrassing about the statement: "The autopsy report showed that the body fluids left in the deceased were mixed with a small amount of soil..."

"There are bodily fluids, which means there was a direct relationship, and no safety measures were taken. But if there is also soil mixed in... Zhang Jun is not an iron man, doesn't he have any scars?"

soil?

Everyone couldn't help but tighten their legs.

If it's dirt... Isn't it painful to death?

Many detectives acted separately, and Zhang Jun was the first to get results.

This guy is very healthy and has no scars at all.

However, during a routine blood draw, a problem was discovered that made Chen Yan a little crazy.

It is precisely this problem that makes the investigation of the case reach a dead end.

Because Zhang Jun was also infected with the antibody deficiency virus.

Judging from the development of the virus, Zhang Jun's infection time was... within one week, which was shorter than Qin Xiaoyu's infection time.

Moreover, the two viruses are homologous.

The same origin means that Zhang Jun's infection with the virus came from Qin Xiaoyu.

Chen Yan was a little confused.

How is this going?

Was it really Zhang Jun who killed Qin Xiaoyu?

However, the situation at the scene...

Did Zhang Jun deliberately confuse the public?

In less than an hour, there was news from Wang Gang and Luan Ping.

Liu Jingting's side went very smoothly. Before catching the first detective team, they all were recruited.

She met Qin Xiaoyu outside the teaching building.

As for why she ran out in the middle of the night when it was raining, it was because of a phone call.

"The phone call said that the monster Qin Xiaoyu went to seduce Professor Jia again. I was so angry that I asked her to argue!"

"Obviously my talent is no worse than hers, but all the school's resources are given to her, and Professor Jia is not willing to teach me alone..."

"Professor Jia wants to hold a solo exhibition for her this time. Why?"

"If she hadn't seduced Professor Jia, how could Professor Jia help her!"

"...I just wanted to scare her. She accidentally fell down from the second floor. I didn't even touch her... Wuwuwu..."

The moment Chen Yan saw Liu Jingting, he knew she was the woman on the teaching floor without comparing her shoe prints. She had the same scent: "Then why didn't you take care of Qin Xiaoyu after she fell?"

"Woo... I was scared, and I heard her scolding me. It must be okay, so I just ignored her..."

"Telephone?"

Chen Yan knew that Liu Jingting was unlikely to lie, but who made that call?

"Liu Jingting's mobile phone has been checked and the number has been traced. The bearer card was sold five years ago and has only been used this time." Luan Ping explained at the side.

The clue...is broken!

Chen Yan squinted his eyes.

He knew that Zhang Jun was definitely not a murderer.

Both he and Liu Jingting are ecstasy bombs.

This murderer planted more than one stun bomb.

However, what kind of murderer is Wu Lu? There must be a motive for killing.

Killing people for no reason is insane.

Moreover, the more the killer does, the more loopholes actually appear.

Even now it seems that all the clues seem to be a mess, and some clues are even contradictory.

It was Jia Xinyi's attitude that surprised Chen Yan.

Although Jia Xinyi is in her 40s, she is well-maintained and looks like she is in her early thirties. Even when she is sitting in the interrogation room, she looks like a gentleman.

"Qin Xiaoyu has a relationship with me and has contact with me every Thursday and Friday."

"I teach her painting in the evening, and she stays with me. We are all voluntary..."

Jia Xinyi's words... were very casual, as if they were taken for granted.

snort!

Chen Yan snorted coldly, not seeing this Jia Xinyi: "Give him a blood test and tell him the results!"

Half an hour later.

In the interrogation room where Jia Xinyi was being held, there was a shocking roar!

Scumbag!

Call the beast!

Two hours later, Wang Gang also came back.

At this time, the sky has brightened, and after dawn, it is dawn.

"Captain, we found it."

The BMW driver has been brought back by Wang Gang and is now in the interrogation room.

As for Qin Xiaoyu’s WeChat...not one, not two,

But three!

Chen Yan is right about one thing.

How many female students in the art college only have a WeChat account?

One of Qin Xiaoyu’s three WeChat messages was for contacting classmates and family members.

In the circle of friends, there are all art exhibitions, dinner parties, charity events, watching movies...

Full of positive energy, yet silly and sweet.

All friend circles are open.

Absolute beauty is the publicity card of Liancheng Art Academy.

As for the other two WeChat...

One was in contact with Jia Xinyi, and the other was in contact with BMW Man.

Interestingly, Jia Xinyi has only one friend on WeChat to contact her.

There are actually many classmates on the WeChat account for contacting BMW men.

Although it is different from the WeChat that Qin Xiaoyu often uses, it is at least half a common account.

Is this girl... really here with the BMW guy?

"died?"

The BMW man still didn’t know that Qin Xiaoyu had been killed.

"Impossible! We met last week. We originally made an appointment to meet today, but she didn't answer my phone calls or reply to her WeChat messages... Wuwu..."

The BMW man actually started crying, he was so sad.

Chen Yan did not go to see the BMW man, but asked someone to draw the BMW man's blood for the same test.

But the result...

Chen Yan was surprised!
