Even Huang Lili could tell something was off.

She looked at Guan Feng and asked in confusion, "Captain, do you mean the murderer isn't actually Yan Jing, but most likely her father, Yan Jiang?"

Guan Feng nodded and said, "I asked Yan Jing for details just now, and several things didn't match up. At first, I thought it might be because Yan Jing was nervous at the time, but when she forgot some obvious details that she shouldn't have forgotten, then something is wrong."

Huang Lili asked, "So what do we do now?"

Guan Feng looked at the group and instructed them, "We can only take two approaches now. On one hand, we need to keep Yan Jing calm and make her think that we've been fooled by her. Gao Dacheng and Zhao Yang will handle the interrogation inside. It'll be a good opportunity to train their micro-expression analysis skills."

"On the other hand, we reinvestigated Yan Jiang. Both the call records and the entry and exit records last night can prove whether he went to the vicinity of Chen Shujuan's rented house. We have temporarily identified him as the prime suspect."

Liu Shengguo volunteered, saying, "Captain, it was my fault for not checking Yan Jing's phone earlier. Leave the checking of the call records to me; I can do it by myself."

Guan Feng nodded and said, "We need to investigate Yan Jing and Yan Jiang's phone calls, especially whether they spoke to each other. The key point is last night. Yan Jing couldn't have gone out without any warning; she must have received a phone call. This is especially important."

Liu Shengguo said, "No problem! I will check it carefully."

Guan Feng said, "You drive one car each and set off first."

Liu Shengguo immediately grabbed his car keys and headed to the telecommunications company.

Guan Feng then looked at Huang Lili, Zheng Hua, Qi Xia, and the others and said, "We still need to investigate the relevant surveillance footage more thoroughly. Zheng Hua and Qi Xia, you two go and investigate the surveillance footage near Chen Shujuan's rented house. Lili, come with me to check the hospital's surveillance footage."

"receive!"

"receive!"

Everyone nodded in agreement.

Next, the group split into two teams.

Guan Feng brought Huang Lili to the hospital's monitoring room.

Guan Feng showed his credentials and said, "We need to access the surveillance footage from the administration building."

When the security guard saw Guan Feng's identification, he shook his head and said, "I'm sorry, officer, we don't have the password to access the surveillance footage from the administration building. Only the security captain has it."

Guan Feng said, "Contact him to come back, but don't say what the specific matter is."

The security guards immediately made contact.

A moment later.

A middle-aged man walked back with a frown and asked, "What's the matter?"

Guan Feng showed his credentials and simply said, "Please retrieve the surveillance footage from the administration building; we need to use it."

When the security captain saw the words "Major Crimes Unit," his eyelids twitched instantly. He then went to the monitor, entered the relevant password, and asked, "Should we leave?"

Guan Feng nodded and said, "Everyone else, leave. You stay."

The security captain immediately nodded.

The other two security guards left the monitoring room.

Guan Feng then asked the security captain, "Do you know why you were asked to stay?"

The security captain shook his head vigorously, saying, "I don't know."

Guan Feng said, "You saw the words 'Major Crimes Team' on my work ID and cracked the code without saying a word. It seems you understand priorities and are a smart person."

The security captain chuckled awkwardly and said, "Mainly, mainly because I've cooperated with you a few times."

Guan Feng said, "Since that's the case, I'll be frank with you. We need to investigate the entry and exit records of your hospital's vice president, Yan Jiang. He should be in a semi-retired state now, retaining his benefits but not involved in any specific leadership work."

The security captain's expression changed, and he asked, "Dean Yan?"

Guan Feng nodded and said, "This investigation is being conducted in secret. You must keep it a secret, and I will keep it a secret as well. So you are a smart person and should know what to do."

The security captain immediately said, "In that case, I'll check the surveillance footage first. I'll see which office Dean Yan is in on the fifth floor!"

He switched the surveillance camera in the administration building to the 5th floor.

The screen was then switched to the time when people were on duty, and facial recognition was activated automatically. A moment later, a figure flashed by. When the security captain saw the second figure, he pointed at him and said, "That's Dean Yan!"

He then looked at the office the other person had entered and said, "It's office number 5."

Guan Feng nodded and instructed, "Lock onto his face and determine when he left the hospital."

The security captain immediately did as Guan Feng asked.

A moment later.

According to relevant surveillance footage, Yan Jiang left the office around 6 p.m.

In the video, he locks the door from the inside, looks around, and then leaves. However, he seems to leave something behind, returns to the room, enters the room, and leaves completely ten minutes later.

Following the route the other party took, Guan Feng continued searching and eventually discovered that after leaving the office, the other party walked out of the hospital building and hailed a taxi on the street.

The hospital's outermost surveillance cameras happened to capture the car's license plate number.

Guan Feng said to Huang Lili, "Write down the license plate number of this car."

Huang Lili immediately took out paper and pen and started writing.

After doing all this, Guan Feng said to the security captain, "The case is still under confidentiality. Yan Jiang doesn't know he's being investigated. You're a smart man; you should know what you can and can't say, right?"

The security captain nodded quickly and said, "Don't worry, I definitely won't risk my job. But please, captains, keep this a secret. Otherwise, I really won't dare to cooperate next time."

Guan Feng nodded and said, "Don't worry, we can definitely do that."

He then took Huang Lili away and drove directly to the monitoring center.

Upon arriving at the monitoring center, Guan Feng presented his credentials, had a brief conversation with the other party, and then asked them to retrieve the time, location, and vehicle information. After some input, it was discovered that Yan Jiang had gotten into the car and headed straight for Chen Shujuan's rented apartment.

As he got closer and closer to Chen Shujuan's house, both of them were on tenterhooks.

With only one intersection left to go before Chen Shujuan's rented house, Yan Jiang got off the bus early and went to a roadside restaurant for a meal.

Fortunately, the store was located at the intersection, and one of the cameras was able to capture the surveillance footage. Guan Feng sped up the progress bar and played the video at double speed, discovering that Yan Jiang was dining in the hot pot restaurant, quietly eating hot pot alone.

The meal lasted for more than an hour, until 8 o'clock, when Yan Jiang finally put down his chopsticks.

Because of the temperature, there was condensation on the glass of the second floor of the hot pot restaurant, and only blurry shadows could be seen. However, it was still clear that Yan Jiang had not left after finishing his meal, and his eyes seemed to be looking outside until he saw a figure before going downstairs.

Guan Feng looked at the time; it was exactly 8:50 PM.

It takes about twenty minutes to get here from Chen Jun's house.

Guan Feng said, "The security cameras here don't cover the first floor. Lily, let's go! Let's go to this hot pot restaurant and see what the father and daughter were talking about."

Huang Lili immediately copied the surveillance videos, saved them, and left the monitoring center with Guan Feng.

And at this time.

Ring ring!

Liu Shengguo called.
