Luke called to report to Red.

Rhett asked Luke to take over the scene and will send forensic and technical teams to the scene for support.

Cyanide is extremely toxic and attacks quickly. Death occurs within seconds to 5 minutes after taking cyanide.

According to the descriptions of two workers, the deceased had been working on the roof for a while, far more than five minutes, so the roof was probably the scene of the first crime.

After being poisoned on the roof, the deceased fell into coma and died within a very short period of time, and fell from the roof to the ground.

Luke inspected the crash site again and found no suspected poisoning tools or items containing cyanide.

Later, Luke climbed up to the roof and asked the deceased's co-workers to identify the location where the deceased fainted.

The house has a conical roof because the house is large and the slope of the roof is not very large, so it can stand firmly.

The Mexican man pointed to the east side of the roof, "Adams was standing here at the time, and he suddenly fell. I didn't even react."

"Why aren't you wearing a safety harness?"

The Mexican man sighed, "The slope of the roof is not big, and we didn't find a suitable place to hang the safety rope. Adams doesn't like to hang the safety rope. He feels that hanging a rope on his body will affect his movement."

It's my fault, I should have advised him, if I insisted that he hang up the safety rope, maybe he wouldn't..."

In Luke's opinion, it doesn't matter whether the safety rope is worn or not, because the deceased did not fall to death, but died of poisoning.

Cyanide is mainly taken through oral administration, respiratory tract absorption and skin contact. Among them, the absorption capacity of skin contact is weak, the dose is generally not too large, and usually it will not cause immediate death.

The deceased was poisoned within a very short period of time, and it was more likely that he had taken an overdose of cyanide orally or inhaled it.

Luke inspected the roof site and found some roof repair tools, but no suspected cyanide poisoning items.

Luke looked at the Mexican coworker on the side and asked, "Did there be anything unusual about Adams before he died?"

"It seems not, at least I didn't see it."

"Did he take anything before he died?"

"I...I don't know." The Mexican worker swallowed.

Luke stared at the other person, "What's your name?"

"Mario."

"Are you feeling unwell?"

"No, I'm fine."

"Then why do you look so nervous?"

"Uh... maybe it's because it's hard for me to accept that Adams is dead."

"Remember carefully, what did Adams do in the five minutes before his death?"

"He just stood on the roof and worked, taking off the broken tiles, cleaning up the construction debris, and then putting the new tiles on... It was just the same job, nothing different."

Luke pointed to his forehead, "You're sweating a lot, do you want to wipe it?"

"Thank you. It's too hot. This season is more suitable for going to the beach for vacation instead of working."

Luke looked at the other party's expression and felt that the other party seemed to be hiding something, "Adams was poisoned to death, not dropped to death.

What he took was cyanide, which is highly toxic and will cause death in a very short time.

Therefore, Adams's death scene should have been on the roof, and there were only you and him on the roof at that time.

Mario, I know you are hiding something, and this is very unwise."

Mario sweated more on his forehead, and his body felt a little weak. He slumped down on the roof and collapsed emotionally, "God, why did this happen?"

"What happened?"

Mario hesitated for a moment and said, "It's very hot today and I need to drink a lot of water, so I brought two bottles of mineral water. I opened one and drank one. Adams saw it and asked me if I had any more.

I handed him another bottle of mineral water.

This is normal, we are co-workers, we cooperate with each other and help each other.

I gave him water and went to work.

Soon, something was wrong with him. He pressed his head and patted his chest, with a painful look on his face, as if he couldn't breathe.

Just as I was about to go over and help him, he fainted and fell from the roof..."

Mario's voice trembled, "I wanted to help him at the time, but I didn't have time, things happened too fast.

I quickly ran downstairs to check, and thought about calling 911 for an ambulance, but when I checked, he was already dead.

That state is wrong, it doesn't look like falling to death...

I thought about his behavior on the roof before, and I guessed that there might be something wrong with that bottle of water."

Luke kept observing Mario's expression, and it didn't look like he was lying. According to what he said, cyanide might have been put into the mineral water bottle, "Where is that bottle of mineral water?"

"In my backpack."

Luke asked, "Why did you poison Adams?"

"No, I never thought of poisoning him. I had no idea that there was poison in the bottle of mineral water, otherwise I would never give it to him."

"You hid the mineral water bottle afterwards, which shows that you were consciously hiding evidence."

"I just don't want to be regarded as a murderer, let alone be arrested and imprisoned. I gave him the mineral water out of kindness, not to harm him.

I am innocent and should not be implicated."

"Are you having trouble with Adams?"

"No."

"Are there any disputes over interests?"

"No, our relationship has always been very good. I have no reason to kill him, and I have never wanted to kill him."

"Where did that bottle of mineral water come from?"

"I picked it up."

"Where did you pick it up?"

"I picked it up in the subway. I took the subway to work today and saw a box of Weissen brand mineral water in the subway passage. There was a note on it saying, "Pick it up for free." I walked over and saw eight bottles of water in the box.

Bottle of mineral water.

I thought someone was doing charity, so I took two bottles of water and put them in my bag to quench my thirst while working.

Who would have thought that it was actually poisoned!" Mario pinched his forehead hard,

"It's not my fault. I didn't expect the mineral water to be poisonous. I'm not a murderer. I'm not... Please don't arrest me.

I am a good person."

Adams is dead, no matter what the difficulties Mario has, he must bear a certain responsibility, and Luke is more concerned about the mineral water box he mentioned.

Luke asked, "How many bottles of water can that mineral water box hold in total?"

"It seems like about twelve bottles."

"Did you also drink a bottle of mineral water?"

"Yes."

"Then why are you okay?"

"I don't know either."

There are a total of 12 bottles of mineral water in a box of mineral water. There were eight bottles left when Mario saw it. There are two possibilities. There are a total of 12 bottles of mineral water in the mineral water box. Before Mario took away the mineral water, four bottles had been taken away.

bottle.

In the second case, there are only eight bottles of mineral water in the box.

In addition, according to Mario, he took two bottles and drank one bottle himself without any problems, which means that his bottle did not contain cyanide.

Luke boldly guessed that the mineral water bottle containing cyanide was not the only one. There might also be mineral water containing cyanide in the box.

It might be one bottle, it might be two bottles, three bottles... or even 11 bottles.

Calculated based on a 50% ratio, the more likely number is four to six bottles.

In other words, there may be more victims.

At this moment, several cars drove to the gate of the yard.

Rhett led a team to the scene, and people from the technical team and the forensic department also came.

Luke told Rhett what he knew, and Rhett looked solemn, obviously aware of the seriousness of the problem.

Luke found two mineral water bottles from Mario's backpack, and sure enough, residual cyanide was found in one of the mineral water bottles. Luke's suspicion was confirmed.

The 'murderer' was found, but the danger was not eliminated, and instead made everyone more worried.

That box of mineral water suspected of containing cyanide was like a time bomb that could kill more people at any time.

In order to prevent more people from being poisoned, Luke led the team and escorted Mario to the subway station where the mineral water box was found.

Everyone rushed to the location mentioned by Mario and found a Wesson brand mineral water box, which also contained two bottles of mineral water. The accompanying technicians conducted tests and found highly toxic cyanide in one bottle of mineral water.

This evidence proves the authenticity of Mario's confession to a certain extent, which means that at least 4 bottles of mineral water were taken away by others!

Luke immediately notified the people at the subway station and asked them to broadcast the situation and ask passengers in the subway to pay attention to safety and not drink mineral water from unknown sources.

Later, Luke reported the situation to Red. As for whether a press conference would be held, that was Red's business.

The focus of the investigation is divided into two aspects. The first aspect is to catch the person who released the poisonous mineral water.

Second, find the person who took the mineral water as soon as possible and remind them not to drink it.

The investigation is mainly divided into two methods. The first method is to check the subway surveillance.
