Zhou Ning hurried over, interlocked his fingers to ensure his gloves were properly fitted, and then cautiously took the tweezers, peering through the magnifying glass for a careful inspection.
The fingernail was crescent-shaped, larger at one end than the other. Half of it seemed to have been constantly exposed on the outer edge of the doorframe's weatherstrip, already showing some dark layering. The other side must have been stuck inside the weatherstrip and thus appeared rather fresh, with faint traces of red nail polish. Of course, there was also a bit of something black at the bottom edge.
Zhou Ning turned back to Xu Dayuan and said urgently,
"Get my phone out for me. I have photos from the crime scene investigation of the April 14 kidnapping case stored there. Find the picture of Fang Yue's severed finger for me."
Xu Dayuan hurried over, took out the phone, scrolled through the album, and before long, found a photo of a severed finger with red nail polish.
