"Captain Li, could this be caused by disinfectant water? After all, disinfectant water is also prone to corrosive effects."
Zhu Tianlei looked at the white spots on the copper sheet, hesitated for a moment and then said.
"Tian Lei, don't you know this in your mind? The ingredients in the disinfectant water simply don't have such strong corrosive power."
Li Min's face was slightly serious.
"Okay, so what do you suspect?"
Zhu Tianlei knew that Li Min's business ability was outstanding. Although he was young, he was definitely outstanding. Otherwise, he would never have become the deputy captain of the county hospital's criminal police team at such a young age.
"I suspect that the drugs that eroded the copper sheets were the drugs that caused Dean Song's poisoning."
Although Zhu Tianlei had already made speculations before, when he heard Li Min express his speculations personally, Zhu Tianlei still felt his heart sinking.
"Isn't this unreasonable?"
"Unreasonable? What do you mean by unreasonable? Is my inference unreasonable or something?"
Hearing Zhu Tianlei's words, Li Min looked at Zhu Tianlei with wide eyes.
"Dean Song's poisoning doesn't happen overnight, but why does he pour the medicine into the sewer every time? Isn't it strange?"
Whether the drug is soluble in water or insoluble in water, it is not necessary at all. Doing so is just setting yourself up for trouble.
"Did you know that Dean Song's family once hired a nurse?"
Li Min did not dwell on this issue anymore, but instead asked about the nursing staff.
"never heard of that."
Zhu Tianlei shook his head. He really didn't know about this matter, and Yang Hua never mentioned it.
"I conducted a survey on the residents of this building before I came here. The residents reported that Dean Song's family hired a caregiver more than three months ago. She was a woman in her 30s and 40s. She lived and ate at Dean Song's house.
This nurse usually does the grocery shopping, cooking, washing and cleaning. The reason why she is called a nurse is because in addition to taking care of the daily life of Dean Song and Zhang **, this woman also needs to help Zhang ** treat the injuries on her feet. However,
Just a week before the incident, this caregiver suddenly disappeared. I have mobilized the police to find this person's whereabouts, but there is no news yet."
Zhu Tianlei couldn't help but admire Li Min even more. He acted vigorously and resolutely and did so much work in just two days.
"Well, I'll go back and find out more about the situation from Director Li. He has a very good relationship with Dean Song in private, so he should be able to get some information."
Li Min nodded, reached out and threw the copper piece into the transparent sealed bag. This was an evidence bag that Zhu Tianlei had seen before.
The two of them left the bathroom together, and Zhu Tianlei subconsciously walked to the north bedroom.
He thought of the photo he saw last time. Maybe this photo could explain the problem.
However, when Zhu Tianlei took down the notebook and opened it, he found that the photos inside were missing.
His hand holding the notebook loosened, and the notebook fell to the table with a clatter.
"Tian Lei?"
Hearing the noise, Li Min turned his head and saw Zhu Tianlei's face not looking good.
"The photos in here are missing."
"Photo? What photo?"
Li Min looked confused. Zhu Tianlei had never told anyone about the photo. First, he didn't think the photo had anything to do with the incident. Furthermore, he didn't know who to talk to about the incident. After all, it happened in Wangwang.
Only Zhu Tianlei, Song Bainian and Zhang ** knew about the incident in Sichuan.
But now, the photo has disappeared, this...
"I once saw an old photo in my notebook. It was a photo of Aunt ** with her classmates when she was young. I didn't expect that it would disappear."
"Did you remember it wrong? Or maybe you dropped it somewhere."
When she heard that it was a group photo, Li Min's nervousness disappeared.
"After I left last time, I put the photos back into my notebook. I won't remember them wrong."
The most important thing is that no one has entered this room since then.
"We haven't checked this house yet, things..."
"I'm not saying you changed the photos, I just...forget it, maybe I just remembered it wrong. There have been so many things recently, so it's not impossible that I remembered it wrong."
Zhu Tianlei waved his hand.
Of course he would not suspect that Li Min and her men had tampered with the photos, because the notebook was still in its original position. He had a photographic memory and clearly remembered the notebook's position and even the tilt angle, and none of this had changed.
This proves that the person who took the photo was very careful. Even the position of the notebook was restored, and probably no clues such as fingerprints were left behind.
Seeing that Zhu Tianlei was a little distracted, Li Min originally wanted to say something more, but finally swallowed his words.
She is clear about the relationship between Zhu Tianlei and Song Bainian. Maybe she can maintain an objective stance on things, but Zhu Tianlei will inevitably have some emotional factors mixed in, which she can understand.
"The house is really clean. I can't even see any oil stains in the sink."
The last place to check was the kitchen. Li Min reached out and wiped it on the sink, and couldn't help but sigh.
Zhu Tianlei had already seen this when he came here last time, and it was indeed spotless.
"Team Li, everything has been checked and there is nothing suspicious."
A male policeman with a Chinese character came over and said to Li Min.
"Okay, I understand. Tell Brother Zhao to arrange for someone to be on duty here. No one can leave here until the case is investigated."
The Chinese-character face nodded and left again.
"Tian Lei, I need to take the things back to the team and hurry up to test them. You still can't relax at the hospital. Don't worry about the health bureau. They are a bunch of losers. They believe that kind of evidence."
Li Min shook the evidence bag containing the copper pieces of the sewer pipe and said to Zhu Tianlei.
Zhu Tianlei couldn't help but laugh when he thought of what Li Min said against Ren Congzhou at the Health Bureau.
"I hope everything goes well for Team Li."
This smoothness, of course, refers to the test results.
Li Min shook his hair, turned around and left without saying anything.
Zhu Tianlei walked around the room again. Except for the disappeared photos, everything was the same as when he came last time.
Who took that photo and why?
Is there really any secret hidden in that photo?
Because Li Min had already left, although the remaining two policemen did not say anything to stop Zhu Tianlei from doing anything, they kept their eyes on Zhu Tianlei, as if they were afraid that Zhu Tianlei would do something to damage the scene.
He was not a policeman, so there was no point in watching more, and it would be embarrassing to stay, so he said hello to the two policemen and left.
Return to the county hospital.
"Director Yang, Dean Song's family once hired nursing workers. Do you know about this?"
"I know, but the several times I went there, the nurse was never there and I never encountered him. What's wrong? Why did he ask about this all of a sudden?"
After Zhu Tianlei returned to the hospital, he couldn't wait to ask Yang Hua.
"You've never seen the carer?"
"No, I just heard what the nurse said. She said that the nurse was good and diligent. Dean Song should also be very satisfied with the nurse. But when you asked me last time, I didn't think it was very important.
I didn’t say..."
Song Bainian explained, but suddenly stopped while he was talking, and then his eyes suddenly widened. (To be continued)
