After on-site investigation and evidence collection, it has been confirmed that the deceased is Pan Long.

Based on the degree of body decomposition, the time of death is around five days.

In the two wine glasses at the scene, one of them only had Pan Long's fingerprints and saliva.

In the other wine glass, besides Pan Long's fingerprint, there were also Liu Hu's fingerprints and saliva.

In addition, the wine glass with Liu Hu's fingerprints also detected residual propranolol drug components.

In other words, the person who drugged Liu Hu on July 22 was indeed Pan Long.

This is the conclusion drawn from physical evidence examination. Before the examination report came out, we had already seen the whole process in the monitoring video of Pan Long's home.

The monitoring video at Pan Long's home meticulously recorded everything that happened in the past week.

At 10:05 p.m. on July 22, Liu Hu arrived at Pan Long's home.

The two of them sat in the living room, and Pan Long poured a glass of red wine for Liu Hu.

"Liu Hu, I advise you to stop, you know the boss's power." Pan Long spoke, his tone relatively soft.

"I've lost so much in business, my creditors are pushing me to the edge." Liu Hu shrugged, "Since I'm going to die anyway, I might as well take a risk!"

"Your creditors may not kill you, but if you anger the boss, you have no chance!" Pan Long still earnestly advised.

"I have his leverage in my hands, dare you touch me?"

Pan Long remained silent.

After a while, he picked up the wine glass and clinked it with Liu Hu.

Liu Hu clinked glasses with Pan Long, finished the red wine in one gulp, and then got up and left.

After watching this segment of the monitoring video, we all understood that it was at this moment that Pan Long drugged Liu Hu.

Liu Hu left at 10:15 p.m. on July 22, and he got into a conflict with Pei Jianye at 10:46 p.m. while on the way.

It matches the timing of the blood pressure medication.

"Why did Pan Long drug Liu Hu?"

Was it arranged by the boss?

As we continued to play the monitoring video, trying to find answers from Pan Long's subsequent actions, the next scene exceeded our expectations.

Less than a minute after Liu Hu left, Pan Long suddenly foamed at the mouth and fell onto the sofa.

In the following days, Pan Long's body decomposed and rotted slowly on the sofa.

Pan Long unexpectedly died all of a sudden.

According to the autopsy report by Lao Wu, Pan Long's cause of death was cyanide poisoning.

But according to the monitoring video, Pan Long only had contact with Liu Hu before he died.

Was it the poison given by Liu Hu?

Or did Pan Long commit suicide?

This segment of the surveillance video and Pan Long's death left us with a lot of mysteries.

Who is the boss?

What leverage does Liu Hu have?

Why did Pan Long suddenly die?

All these strange phenomena left us puzzled.

After watching the monitoring video, Chen Wei immediately conducted further investigations into the social relationships between Pan Long and Liu Hu.

They checked all of Liu Hu and Pan Long's contacts, trying to find the whereabouts of the "boss."

They even accessed Liu Hu's personal information to search for the "leverage" he mentioned.They investigated Pei Jianye's situation as well.

However, after investigating for a month, they still couldn't find any useful clues.

The case hit a dead end.

The case couldn't progress further.
