"Did you find out who Petyr had contact with before he died?" The officer continued.

Lilith recalled, telling the officer who she remembered, and the officer gradually talked to those who had come into contact with Petyr.

Xia Han eavesdropped on the conversation between the police and the eight people, while analyzing who was the most suspected.

According to surveillance video recordings, Petyr drank water before his death and was seventeen minutes after his last drink.

The last time I drank water, there was no poison, which means that someone poisoned it in the past 17 minutes.

And in these seventeen minutes, there were two hosts, Lilith, a blonde male singer, and a woman who delivered drinks.

Principal Hayin, another male judge, the first female singer to sing on stage, and Lan Pengwei, the cross-scar man, had all come into contact with Petyr seventeen minutes earlier, which can be presumably ruled out based on the time.

Of the nine suspects, only four remain.

So how did the murderer poison the water cup in these seventeen minutes?

Xia Han carefully observed the surveillance video and the video taken by the audience, analyzing it from different angles.

The people who have touched the cup are: the hostess, who stuffed a note under the Petil cup; Lilith, the two cups were so close together that their hands touched; When the blonde singer stepped off the stage to hug Petyr, his clothes touched the cup.

It's strange that there are water cups on the table, why does a female staff member come over to deliver drinks?

The male host had touched Petyr, but he hadn't touched the cup. Can be excluded first.

Xia Han asked Xiong Shuangzhi to check the background of the four people, and the suspect was found, but what was the motive for the crime?

Now the police asked Monica, the female staff member who brought water to Petyr.

"Monica, you're Petyr's assistant, he has a glass of water on his table, why do you want to deliver drinks?" The officer asked.

"Petyr doesn't like to drink plain water, he likes to drink Coca-Cola, and the organizer didn't prepare it, so I went outside and bought it for him." Monica, with curly red hair, replied.

Although she is wearing work clothes, her appearance and figure are also very standard.

"You didn't tell the organizers about Petyr's preferences in advance?" The policeman continued to ask.

"I thought that Petyr also came to be a judge of the competition last year, and the school leaders knew about the arrangement, so they didn't explain it extraordinarily." Monica's eyes twinkle as she spoke.

………………

Xia Han, who practices martial arts, naturally has good eyesight and can see Monica's subtle expression clearly.

"Zhizhi, you check Monica's personal relationship with Petyr." Xia Han said to Xiong Shuangzhi with a headset.

"Well, by the way, I found out that Lilith was Petyr's lover, and the two had a few trysts at the hotel. The blonde male singer is the younger brother of Petyr, and is now the object of cultivation in Petyr's company. Xiong Shuangzhi told Xia Han about the two people he had found.

"Roger."

Xia Han continued to eavesdrop on the police's interrogation of the hostess.

The police did not get the results so quickly when they called up the surveillance and checked the anomaly, and the police did not ask about the hostess stuffing the note.

Xia Han went over and said to the chief of police: "Officer, I remember that I saw the hostess in my seat stuffing a note for Petil and touching this cup. Hope this helps you guys solve the case. ”。

"Okay, thank you, we'll look into the situation." The police chief was deeply impressed by this Chinese female forensic doctor, and the silver needle drug test method also made him gain insight, and he subconsciously had some trust in this female forensic doctor.
