8 bottles of mineral water kills 3 lives.

Just to the crime scene alone, Luke ran away three times today.

Tom's house was also cordoned off.

The technical team and forensic scientists were short of manpower and were delayed in arriving.

Luke wears gloves to inspect the scene.

Judging from the available evidence, young Tom is likely to be the poisoner, and poisoning requires tools.

As long as the relevant crime tools and cyanide are found, the other party's suspicion of poisoning can be proven.

Luke carefully observed the mineral water bottle and placed it under the sun. There was advertising paper on the outside of the mineral water bottle. Luke faintly noticed that there seemed to be a small black dot on the inside of the advertising paper.

Luke cut open the advertising paper with scissors and found that the mineral water bottle had a pinhole-sized bump, which was sealed with glue on the outside. It was difficult to identify without careful observation.

Luke speculated that this pinhole was probably where cyanide was injected. This would ensure the integrity of the bottle cap and prevent drinkers from becoming suspicious.

Hard to find.

Subsequently, Luke began to search Tom's home, mainly looking for cyanide, syringes, glue...

However, Luke and others searched the house and still could not find these items.

Hidden somewhere else?

If the other party is the real poisoner, what is the purpose?

Why commit suicide by taking poison?

Luke also found no suicide note at the scene.

There are many doubts, and it is difficult to explain based on the physical evidence at the scene alone.

Luke looked at Tom's mother, who looked sad, holding a photo of Tom, sitting on the ground and crying silently...

At this time, Luke did not want to disturb the other party, but the case was urgent and no one knew whether the poisoner placed 9 bottles of water or 12 bottles of water in the subway.

In order to avoid more victims, Luke must find out what happened to Tom.

"Ms. Lewis, please have your condolences."

Tom's mother didn't respond and didn't even look at Luke.

"I know you are sad now, and I understand how you feel. Tom is still young, and he should not leave like this...

We are all very sorry.

But the fact has happened, and all we can do is find the murderer of Tom and avenge him.

This way he can leave with peace of mind."

Ms. Lewis slowly raised her head, "Why did this happen? Why did Tom die? Why?"

"We don't know, we are investigating."

"Liar, you must know this, otherwise why would you come to my house?"

"As I said before, we are investigating a poisoning case. Tom has a certain connection with this case. We are here to investigate him. We did not expect that he would die."

"How did Tom die?"

"Although it has not been technically identified, I speculate that it is probably cyanide poisoning. Do you have similar items at home?"

"I don't know what cyanide is at all. We have never stored any poisonous things in our house. Why is my son related to the poisoning case? How did you find him?"

If Luke wants to get valuable clues from the other party, he must first gain the other party's trust. He said, "We received a call this morning and there was a poisoning incident. According to the investigation, we found that someone put poisonous mineral water in the subway station.

We rushed to the subway station to check the surveillance and found that Tom had entered the subway carrying a box of mineral water.

We suspect that he may be the poisoner."

"Impossible, Tom can't be a poisoner. Although he is a little naughty, he is essentially a good boy. And he is only twelve years old. He doesn't understand anything. He may not even know what cyanide is. And

How is it possible to poison someone with something like that?

Besides, if he was the poisoner, why did he die?"

"Yes, this is what I'm suspicious of." Luke asked, "Has there been anything unusual about Tom recently, such as any trouble or trouble?"

"No."

"Has he been suicidal before?"

"No! He is a very optimistic child. Although our family is not very wealthy, I have always taught him that people can be unsuccessful, but they cannot be unhappy.

He will never commit suicide, absolutely impossible."

"Does Tom have any friends who are dangerous or have antisocial personalities?"

"Not that I know of."

"Has Tom been living with you?"

"Yes."

"When was the last time you saw Tom?"

"Around eight o'clock this morning, I went out to do some errands and went shopping at the supermarket. I bought salmon, which he likes to eat. I originally planned to make salmon sushi for him... I bought it...

God, why are you so cruel!"

"What was Tom doing at that time?"

"He just got up and was having breakfast."

"Did he say where he was going? Who he wanted to meet?"

"I was in a hurry this morning, so I didn't bother to ask. I was too careless."

"We found forty dollars in Tom's pocket. Did you give it to him?"

"No, I only give him ten or twenty dollars each time, and he spends it quickly every time. There is no way he has that much money."

From the interview just now, it seems that Tom's mother doesn't know much.

Luke also found no signs of lying.

However, Tom's mother is now in great sadness and has great mood swings. Even if she lies, it is not easy to tell.

Although he didn't get any clear clues, Luke still extracted some valuable clues from Tom's mother's words.

As the saying goes, a child knows better than his mother. Since Tom has been living with his mother, her mother should be one of the people who knows her best.

Since Tom's mother said that he has a cheerful personality and is unlikely to have suicidal tendencies, the possibility of Tom committing suicide has been reduced a lot.

Assuming that Tom did not commit suicide, it proves that he did not know that the bottle of mineral water was poisonous.

It is possible that he is not a real poisoner, considering the forty dollars in his trouser pocket.

Luke boldly speculated that in order to avoid being photographed by the surveillance cameras in the subway station, the real poisoner hired Tom to put the mineral water box in the subway station, and the forty dollars was a favor fee for Tom.

After Tom put down the mineral water tank, he took a bottle of mineral water and took it home to drink. He was poisoned and died.

According to Mario's description, there were eight bottles of mineral water in the box when he went to get the mineral water. Plus the bottle that Tom took away himself, there should be at least nine bottles of mineral water.

The police have only investigated the whereabouts of eight bottles of mineral water. Tom took one bottle, Mario took two bottles, the homeless man took three bottles, and there are two bottles left in the box.

In other words, at least one bottle of suspected poisonous mineral water was taken away.

Maybe four bottles...

At seven o'clock in the evening.

Robbery and Murder Division Conference Room.

Susan called everyone to a meeting.

Susan put a document on the projector with a solemn expression, "After forensic identification, the three deceased people died of cyanide poisoning.

Judging from the time of death, the first deceased was a homeless man in the subway station. No identification document was found, and the true identity of the other person is not yet known.

Construction worker Adams and teenager Tom died very close to each other, both around ten o'clock in the morning.

The three deceased people all died within a very short period of time after taking cyanide. Among them, Adams, a construction worker, fell from the roof and had some scratches on his body. There were no signs of being tied up or abused.

No obvious injuries were found on the bodies of the deceased Adams and Tom, who probably voluntarily drank mineral water containing cyanide."

Susan changed another piece of information and said, "The technical team investigated the murder scene of the three deceased people and the location where the mineral water bottles were dropped.

Only Tom's fingerprints were found on the mineral water box, and no fingerprints of the suspected poisoner were found on the mineral water bottles.

Poisoners are cunning."

Jackson turned his pen and asked, "Could the poisoner be that young boy Tom?"

Luke said, "I talked to Tom's mother. According to her, Tom is mentally normal, has no suicidal tendencies, and has no reason to retaliate against society. I am more inclined to believe that he was just hired by a real poisoner and was poisoned by a real person."

The person took advantage of it.

If Tom is not dead, we can still find clues to the real poisoner based on his confession, but since Tom is dead, it will be difficult to continue investigating this clue."

The deputy said, "Since we can't find any clues about the poisoner, let's analyze it from the motive.
To be continued...
