"But are you sure no one else besides your father will come into contact with the collar?"
Xia Zhining's heart skipped a beat when she heard the words "your dad." So...
It was his children who poisoned Mr. Wu!
Doctor Huang tampered with the collar and poisoned it, fearing that other people would be poisoned if they came into contact with it.
Amber once told her that because her collar was inlaid with expensive accessories such as gems and diamonds, the beauticians were worried about not being able to compensate for the damage, so they would wear gloves when putting on and taking off the collar for her.
Dr. Huang is well aware of this, so he can conclude that the staff of the pet hospital will never touch the collar with their bare hands.
What he was really worried about was that after Amber was sent home, the first person to touch the collar was not their target of poisoning, Mr. Wu.
Xia Zhining quickly sent a message to Captain Wang, asking him to bring police officers to the pet hospital quietly to prepare to arrest the person.
While editing the message, Xia Zhining asked the cockatoo, "Sister Feng, did you hear the voice of the person who was on the phone with Dr. Huang?"
"What did that man say?"
The cockatoo shook his head regretfully: "I stretched my neck to listen, but the voice on the other end was too quiet."
Suddenly, his eyes lit up as if he had thought of something: [Oh, right, Dr. Huang said something when he first answered the phone: "The construction work on your end is a bit noisy, I can't hear you clearly."]
construction?
Xia Zhining immediately thought of her designer Bai Xiao, who had been helping Wu's house redecorate the tea pavilion these days.
The tea pavilion at Wu’s house is under construction!
The person who spoke with Doctor Huang was able to ensure that Mr. Wu was the first person Amber came into contact with after returning home because he was also at Wu's house at the time.
"Thank you, Sister Feng. This clue is very important!"
Xia Zhining quickly sent a message to Captain Wang: "Captain Wang, quickly check which of Mr. Wu's two sons and two daughters went to the teahouse at 2:00 PM yesterday!"
The cockatoo curiously watched Xia Zhining's busyness. "Spotting someone doing something sneaky, so this is called a clue?"
Xia Zhining nodded: "Yes! Amber's collar was most likely smeared with poison. We are investigating this poisoning case."
"The police will reward the animals who provide clues!"
The cockatoo suddenly understood, his eyes brightening: "I have another clue!"
[After Dr. Huang finished his phone call, he found a thick black bag and threw a small bottle and the gloves he had been wearing into it.]
[The thick black bag was hidden in the corner of the utility room. He never went in again, so the bag should still be there!]
Xia Zhining stood up immediately: "Where is the utility room? Take me there!"
The cockatoo quickly led the way, and Xia Zhining had already arrived at the door of the utility room.
She had to stay here to prevent Dr. Huang from coming in and destroying the evidence.
Perhaps because the poison was extremely toxic, Dr. Huang didn't dare to throw the thick black bag into the trash can. He could only hide it and then find a way to deal with it.
Four police officers sent by Captain Wang arrived quickly!
They were divided into groups of two and then moved together to find the suspect Huang Li.
The other group was fully armed with masks and gloves and was searching for the thick black bag in the utility room.
With the guidance of the cockatoo, the two police officers easily found the thick black bag!
They opened the thick black bag and found a pair of gloves and a small transparent medicine bottle inside.
One of the older officers twisted the thick black bag's material between his fingers.
He raised his eyebrows. “This bag is very thick and has a grainy surface. It’s high-density polyethylene!”
Xia Zhining immediately remembered: "High-density polyethylene... I often used bags made of this material to package hazardous chemical waste when I was in the lab."
The older police officer nodded, his eyes flashing with appreciation: "That's right, ordinary garbage bags don't use this kind of material at all!"
"This black bag you and the parrot brought us to is very likely the key evidence containing the poison!"
