Disinfectant water ......

I don't know why, Bai Yaqing thought of the hospital, and the bacterial content and some substances in it are all available in the hospital.

Perhaps the killer was a hospital worker who accidentally got on the ...... during work

Hospital staff...... This is also a hospital, so why not start here?

Bai Yaqing thought about it, and immediately went to do it.

Bai Yaqing took the key to the locker and went to find the nurse at the nurse station.

"Miss Nurse, I want to ask, do you recognize this key?"

The little nurse at the nurse's station didn't recognize where the key was, she was just a little nurse who had just come here for an internship, and she didn't know it, and she couldn't recognize it at all.

"This ...... I don't know ......"

"Will you take a closer look?"

"Otherwise, I'll help you find our head nurse."

"Okay, thank you!"

The little nurse turned around and went in to find the head nurse.

"What's the matter? Why are you calling me out in such a hurry? ”

"The head nurse is it? That's right, where do you see this key? Bai Yaqing gave the key to the head nurse.

The head nurse looked at the ziplock bag with the key...... It's a locker's.

"It's a lot like locker keys in our hospital."

"Are you sure?"

"I'll show you there." Because the head nurse also knew that Bai Yaqing was a policeman, he didn't say anything, and took her to see her directly.

"This is it." The head nurse took her into the locker and pointed to the box marked on the key.

"Okay, thanks."

Bai Yaqing put on her gloves and opened the locker.

There are two things in it, it seems to be a diary, and there are some photos on it, which are related to the deceased, and one of them was crossed by him!

"Ahh Over here...... How could there be such a thing in this......" The head nurse was also surprised when she saw the photos.

"These ...... Who is this locker for? Bai Yaqing turned her head and asked the head nurse.

"This ...... This is the anesthesiologist's ......"

Anaesthetist? Bai Yaqing immediately closed the locker, and the photo on the door of the cabinet was the owner of this cabinet.

"Yes, that's him! I didn't expect him, he was actually this kind of person......"

Bai Yaqing immediately took a photo of the cabinet door and sent it directly to Liu Fei at the police station.

"Liu Fei, find out who this person is."

"Okay."

……………………

Ten minutes later, Bai Yaqing received Liu Fei's message and had already found out.

This person is an anesthesiologist in this hospital, and he is also a well-known anesthesiologist, and he has a very good grasp of dosage.

"This man...... Or is it a senior anesthesiologist here, how can he kill people......"

This senior anesthesiologist, who wants to have an income, is a high-income group, how can he be so stupid and do these things...... You know, if these things are poked out, it will ruin your reputation and empty both people and money......

In the ward, Bai Yaqing looked at the information on the mobile phone intently. At this time, Zhang Zijun was sleeping and resting in the police station, and he heard Liu Fei's voice working.

"Liu Fei, what's wrong?"

"The team leader should have found the murderer and sent a photo to check the information."

"I'll see."

When Zhang Zijun saw this person's profession, he had to admire Bai Yaqing's reasoning ability, and he was indeed an anesthesiologist.

"I'll go to the hospital."

……………………

Bai Yaqing was at the hospital, and went over with Shasha to find the anesthesiologist.
