Officer Feng waved his hand: "We can't confirm anything for now; we're still investigating. However, at this point, it's clear that Zhang Shan is a suspect, while Zhang Yao has been out of town and hasn't come to Beijing."
After deeper investigation, we discovered that Zhang Yao's mother, Shen Zhen, had interacted with Tian Yaru. Additionally, a distant relative, Shen Dahai, runs a general store in Kaihua, which connects many clues back to them."
Li Si thought to herself, so that's how it is. Given how strict Beijing has become about managing dangerous substances, it seems implausible that someone as gravely ill as Tian Yaru could have obtained them. Something just doesn't add up.
So not only Zhang Shan, but even Zhang Yao's mother is involved?
Now that I think about it, perhaps it makes sense. After the forum post incident, Zhang Yao was sent to a psychiatric hospital by Long Wu. Once Zhang Yao came out, it's unlikely she wouldn't have shared it with her closest confidante.
