The Forensic Doctor Better Than a Detective Chapter 302 - 192: Clue Broken, Stalemate

"Hmm!"

Jiang An nodded in response.

"I’ll follow Mr. Zhang’s instructions."

Soon, Jiang An, Zhang Yean, and Wan joined the surveillance investigation team.

Jiang An glanced at the surveillance investigation equipnt, which was rely a display screen and had not yet evolved to the level of using software for capturing special elents.

At this mont, the 100-square-ter office fell silent instantly.

Everyone focused their gaze on the display screen.

They didn’t miss a single person in their view.

After two hours, Zhang Feng excitedly said, "Found him!"

"That mysterious man appears in this footage."

Instantly, others moved over.

In the surveillance video, a man was seen wearing a baseball cap and dressed in black, moving suspiciously.

"This person’s attire and the timing of his appearance entirely match the clues provided by Zhang Biao."

Zhang Feng spoke while fixating on the monitor.

At this ti, Jiang An was also closely observing the man’s moving direction.

In the footage, the man’s figure beca increasingly distant until he disappeared.

Imdiately after, based on the man’s movent direction, Zhang Feng moved the mouse and clicked on the next surveillance file.

This was a private cara record of a grocery store owner. The quality of the surveillance footage was not high, but one could see the shape of the person.

One of the officers asked, "Where is this moving towards?"

"Ahead is McDonald’s!"

"On that day, Zhang Biao and Li Lan ate there for lunch."

Five minutes later, the man in black disappeared around the corner.

Then, Zhang Feng moved the mouse to open other video surveillance folders.

After 30 minutes, nothing of the man in black appeared in the video surveillance.

"Strange?"

"Where did he disappear to?"

Mr. He raised his hand to touch his chin, falling into contemplation.

Mr. Zhang once again scanned the location of the surveillance records in the folder.

He squinted slightly, with the road layout where the man in black disappeared vividly in his mind.

The place did not allow motor vehicles, only pedestrians.

In his view, these surveillance cara locations already covered all exits of that place.

"Could it be he has been hiding all along?"

After thinking for a while, Jiang An said, "Mr. Zhang, how did Zhang Biao and Li Lan leave?"

"According to Zhang Biao’s recall, after they ate at McDonald’s, they went down into the basent garage from the store."

Jiang An then asked, "Is the basent garage connected?"

"Not connected!"

As soon as these words were finished, Mr. Zhang suddenly realized.

No, the two places had already connected north and south two months ago.

"Two months ago?"

Zhang Feng instantly stood up and paced back and forth in the office.

After a minute, he muttered to himself, "I rember now!"

"At that ti, the garage had just connected and was in a trial operation phase."

"The man in black could completely enter the basent through the adjacent Chinese restaurant."

No sooner said than done, Mr. Zhang quickly stated, "Mr. He, go and obtain the surveillance from that Chinese restaurant and the garage imdiately."

"Yes!"

Promptly, Mr. He led two officers quickly out the door.

Twenty minutes later, Zhang Feng’s phone rang.

When the call was connected, Mr. He said, "Chief, there’s no surveillance data found here."

"What’s going on?"

"The restaurant’s surveillance system was updated a month ago, and the data was cleared."

"As for the underground garage surveillance, because it was in the trial phase, the system was not compatible and did not save data."

Upon hearing this, Zhang Feng instantly flew into a rage.

The surveillance tracking ended up disappearing here.

Since this man in black entered the basent, it’s highly possible he had a vehicle.

If there were surveillance records, it might lock down this person’s identity.

Just as everyone was feeling a bit disheartened, suddenly, a criminal investigation officer ran in.

"Chief Zhang, there’s a discovery at the entrance surveillance of the campus comrcial street."

Upon hearing this, Zhang Feng quickly turned around.

"Go! Let’s go have a look!"

Soon, everyone arrived at the adjacent office.

Seeing the chief co over, the officer hurriedly said, "We reviewed the monitoring at the entrance of the campus, and in cara 7, shortly after Li Lan appeared, a man wearing black clothes and a black baseball cap walked into the surveillance."

"Moreover, the direction of their movent was entirely the sa."

Mr. Zhang nodded, "This cara is a bit far away. Do we have a better one?"

Subsequently, the officer manipulated the mouse again, opening other surveillance record folders.

An hour later, after observing all the surveillance caras, no sign of that man was seen.

Mr. Zhang glanced at the position of the surveillance records, speaking in a deep voice, "This cara is at a high location, making it hard to see clearly."

"However, judging from the size and physique, it should not be a major issue."

At this mont, Jiang An said, "I rember Zhang Biao said Li Lan walked towards the school after getting out of the car."

The young officer glanced at Jiang An, "The direction both of them moved towards is the direction of the art college."

"Can the school’s surveillance be obtained?"

"Soone has gone to retrieve it!"

As soon as he finished speaking, a slightly chubby man ca running up, panting.

"Mr. Li, we don’t need to personally obtain the surveillance!"

"I’ve asked a friend in the school security departnt to transfer it directly."

"This way, our investigation speed will be faster."

Five minutes later, the computer beeped with an incoming transfer.

"The files are here!"

Soon, everyone once again fixed their eyes on the display screen.

The officer instantly opened the surveillance files.

Five minutes later, the footage showed Li Lan walking alone into the campus entrance with a shoulder bag.

Seeing this, everyone was quite baffled internally.

"Why is there no one else?"

"Could it be that the previous person was not the mysterious man in black?"

"No way!"

....

For a mont, many people started whispering, speculating amongst themselves.

Considering the prior cara’s high position and unclear image of the person, even Zhang Feng felt a bit unsure!

He turned his head to look at Jiang An.

At this mont, Jiang An was closely observing the monitor screen.

Two minutes later, Mr. Zhang asked, "What are you thinking?"

Jiang An answered, "I am comparing and observing Li Lan’s walking posture."

"Walking posture?"

Mr. Zhang was sowhat surprised.

This term was quite novel.

He continued, "I recall from the caras on the pedestrian street, Li Lan walked briskly with confidence, swinging her arms widely."

"Even through the earlier high-positioned cara, you could still see her head held high, walking cheerfully."

"But!"

"From what the school’s surveillance records show, I feel Li Lan’s walking posture becos sowhat heavy."

"Her head lowered, taking small steps, with no visible arm movent."

At this ti, the young officer again brought up the surveillance video of Li Lan entering the school.

With Jiang An’s prompt, everyone focused their observation on Li Lan’s walking posture.

Monts later, one of the officers comnted, "It really is like that! This clearly indicates she’s preoccupied."

Zhang Feng also nodded gently.

"Why would it happen like this?"

"Could sothing have occurred on the way?"

After contemplating for a while, Jiang An said deeply, "I suspect there might have been direct contact between the man in black and Li Lan."

"Direct contact?"

Instantly, everyone appeared surprised.

For Jiang An’s speculation, Mr. Zhang didn’t find it unreasonable.

In the surveillance, the two were walking in the sa direction.

Li Lan’s mood changes could be analyzed and inferred through her physical movents.

Monts later, Zhang Feng said, "It’s entirely possible."

He turned his head and asked, "Is there a cara midway?"

The young officer shook his head, "We looked at the surveillance distribution map of that road, there is no surveillance."

Mr. Zhang furrowed his brows heavily.

How did this lead break again?

Jiang An looked at the surveillance screen and said in a deep voice, "If they made contact, what might have happened?"
